Preface and Safety regulations
1. Preface
This manual is split up into two parts:
- Manual for the user (chapters 1 up to and including 4)
- Manual for the installer
This manual contains a glossary (chapter 10).The glossary gives a
description of the words which are not used in common
parlance. Also, an index is included.This enables you to easily find
a specific subject in the manual.
After reading the User Manual, you are able to use the IRT 30
clock thermostat.You can enter the desired program, so that you
have the desired temperature at every moment of the day.This
manual gives an answer to the following question:
“What do you have to know to control the IRT 30”.
The more technical issues can be found in the manual for the
installer. In this section you can also find the mounting and
installation instructions.The installer should also set the IRT 30.
In the event of malfunctions, you can find information about this
in chapter 9.You can also contact your installer.
2. Safety regulations
- Never disassemble the thermostat, and do not drop it on the
floor; the thermostat contains vulnerable electronic parts and
sensitive sensors.
- Avoid high temperatures, moist and dusty surroundings.
- Do not use liquids or cleaning agents to clean the thermostat.
- Switch off the power supply of the CH before you install the
thermostat. Make sure the power supply of the CH is actually
switched off.

3. Brief description of the IRT 30
3.1 Introduction
The IRT 30 clock thermostat has been specially developed for the
use with boilers fitted with the universal burner auto unit UBA-
4000.The IRT 30 is designed for wall-mounting and is powered
via a connection to the boiler.Thus, the thermostat does not use
any batteries. By making use of a computer program, the
thermostat continuously receives data from the boiler and the
other way around.With this information, the thermostat is able
to give instructions to:
- comfortably heat your home,
- supply the boiler with hot water at the right time,
- save as much energy as possible.
You can program the IRT 30 with a maximum of 70 switching
points for one week. Furthermore, you can change the switching
points, and remove or insert them.
Switching point
A switching point is a setting in your clock thermostat. It is a moment
in time at which you desire a different temperature.To set this, you
have to enter the desired time and the desired temperature.
(In paragraph 4.4 this will be explained in detail).
In doing so, you can refine the temperature regulation of your
home.
The IRT 30 is suitable for three kinds of temperature regulation:
- room temperature controlled regulation
- weather dependent regulation
- weather dependent regulation with room temperature
compensation.
The kind of temperature control which is applicable to you, is the
starting point for setting the IRT 30.Therefore, the following
paragraphs will describe the three kinds of temperature
regulations.

Brief description of the IRT 30
3.2 Selecting the correct kind of temperature
regulation
In paragraph 3.1 the three kinds of temperature regulation for
which the IRT 30 is suitable, are mentioned:
- room temperature controlled regulation
- weather dependent regulation
- weather dependent regulation with room temperature
compensation.
For the last two mentioned, it is necessary to place an outside
temperature sensor (which determines the outside temperature
and sends this information to the boiler) on the outside wall of
your house.This must be a wall where the sun does not shine on
directly and where the outside air can freely circulate around the
sensor.
Room temperature controlled regulation
This is the simplest principle of regulation. It gives a high comfort
level and has a high performance.To ensure the installation will
operate according these principles, a number of conditions
should be satisfied.There should be a room in your house in
which the temperature is representative for the temperature in
the rest of your house.This must be a room where, for example,
the fireplace does not burn all day long, or the outside door or
windows are not open very often. Such a room is called a
reference room.
Reference room
A reference room is a room (for example the living room) where
a temperature can be measured which is representative for the
entire house.
We assume that the temperature in other rooms (for example
kitchen or bathroom) is equal to the temperature in the reference
room.
An other reason to appoint a specific room as reference room is that
most of the time will be spent in this room.Therefore, it is important
that the temperature regulation of this room is correct.The other
rooms in the house can have a lower (or higher) temperature.
English - 5
English
Brief description of the IRT 30
What does room temperature controlled regulation mean?
- The IRT 30 continuously measures the temperature in the
room where it is fitted.
- The measured temperature will be compared with the desired
(set) temperature.
- The IRT 30 determines how intensely the boiler has to burn to
heat the CH-water, in order to achieve and maintain the
desired temperature.
- The IRT 30 calculates the lowest possible water temperature,
so that the boiler has to burn no more than necessary.
- In general, the boiler will therefore burn for a longer period at
a lower capacity.
- By means of this principle of control, hot CH-water is available
nearly all the time. If, in another room, a closed radiator valve is
opened, the room will quickly be brought up to temperature as
a result.
When to apply the room temperature controlled regulation?
- When the house is heated only by means of radiators.
When not to apply the room temperature controlled regulation?
- When there is no appropriate reference room in the house to
install the IRT 30.
- When your house is heated (also) by means of floor heating,
air heating or convectors.
In practice, the room temperature controlled regulation is the
principle which will be selected in most cases.
Weather dependent regulation
This is a principle of regulation in which the determination of the
CH water temperature is achieved by the outside temperature
and a number of preset values in the IRT 30.This can be necessary
when no reference room is available. Furthermore, this principle
is used in buildings where it must be possible to heat the rooms
independently from each other (for example old people’s homes
or office blocks). For this principle, the separate rooms should be
equipped with radiators with thermostatic radiator valves, in
order to regulate the temperature in each room.
6 - English
English
Brief description of the IRT 30
In a house which is heated by floor heating, the temperature
fluctuations should not become too large. Furthermore, this kind
of heating heats up and cools down very slowly. In this situation,
weather dependent regulation is a good choice, because with this
regulation the heating intensity of the boiler will only be affected
by the outside temperature. Because of this, changes will take
place relatively gradually.
What does the weather dependent regulation mean?
- The heating intensity of the boiler is determined by the outside
temperature and specific preset values on the IRT 30 clock
thermostat.
- When the outside temperature drops, the boiler will burn
more intensely and heat the CH water to a higher temperature
(up to a preset maximum temperature).
- When the outside temperature rises, the boiler will burn less
intensely and heat the CH water to a lower temperature
(up to a preset minimum temperature).
- The rooms will be heated by the continuously circulating
CH water.
- The temperature in the rooms to be heated can be regulated
by means of thermostatic radiator valves.
When to apply weather dependent regulation?
- When your house does not have a suitable reference room.
- When you want to precisely regulate the temperature in more
than one room.
When not to apply weather dependent regulation?
- When your house does not comply with the above mentioned
criteria.This is a relatively less economical regulation principle,
so you should apply this kind of regulation only if strictly
necessary.
Weather dependent regulation with room temperature
compensation
This kind of regulation is a derivative of the weather dependent
regulation.With this principle, the CH water temperature is
determined, in first instance, by the outside temperature and the
preset values on the IRT 30. However, the thermostat also
measures the temperature in the room where it is fitted.
English - 7
English
Brief description of the IRT 30
This information is used to make minor corrections to the signal
to the boiler, so that the desired temperature can be reached.
The temperature in the room where the thermostat is fitted, is
determined by the thermostat itself.The temperature in all other
rooms can be regulated by means of the thermostatic radiator
valves. Basically, you can choose this kind of regulation in the
same cases as you would choose the weather dependent
regulation without room temperature compensation.A suitable
reference room should be available in the house.
What does weather dependent regulation with room temperature
compensation mean?
-
The CH water temperature will be determined, in first instance,
by the outside temperature and the preset values in the IRT 30.
- The IRT 30 also measures the temperature in the room where
it is fitted.
- On the basis of the measured room temperature, the IRT 30
adapts the water temperature of the CH automatically.
- The rooms will be heated by the continuously circulating water.
- The temperature in the room where the thermostat is fitted
will be determined by the thermostat itself.
- The temperature in all other rooms which must be heated can
be regulated with the thermostatic radiator valves.
When to apply weather dependent regulation with room temperature
compensation?
- When you want to precisely regulate the temperature in more
than one room and there is a reference room available.
When not to apply weather dependent regulation with room
temperature compensation?
- When your house does not comply with the above mentioned
criteria.This is a relatively less economical regulation principle,
so you should apply this kind of regulation only if strictly
necessary.

3.3 Operating controls
The IRT 30 can be controlled on two levels (refer to the fold-out
page, figure A and B):
1. With the flap closed (figure A); you now have access to:
- The temperature adjustment knob, for manual adjustment
of the temperature,
- the + and – push buttons, for temporary adjustment of the
temperature within the clock program.
2. With the flap open (figure B); you now have access to
10 operating controls:
- One adjustable program knob, by means of which you can
scroll through a program and raise or lower the values,
- Nine push buttons for several functions like time setting,
day setting, program setting etc.
The principle of this operation is ‘push and turn’:
-
Select the key of the function you want to change and hold it.
- Simultaneously turn the program knob clockwise to raise
the value, or:
- Simultaneously turn the program knob counter-clockwise
to lower the value.
In chapter 4, operation will be explained in detail.
3.4 Information on the display
The screen (also referred to as display) shows information about
the operation of the boiler and the thermostat by means of digits
and symbols.The display in figure 3-1 shows all possible symbols.
Beside this, the meaning of each symbol is described.

4. Operation
4.1 General
Read this manual carefully, so you can operate the IRT 30
correctly.Your installer can inform you in detail about the use of
the clock thermostat.
Efficient heating and ventilation
- Avoid extreme temperature settings and quick changes of
temperature in the program (difference between day and night
temperature may not exceed 5
°C).
- Do not let the temperature of the rooms drop too low during
night setting. (Your CH must burn longer and more intensely to
heat up walls which are cooled down).
- Make sure your house has a good atmospheric humidity,
especially during the cold months.You can achieve this by
placing indoor plants or humidifiers.A good atmospheric
humidity contributes to a pleasant climate in your house.
- Ventilate well (briefly more ventilation takes less energy than
ventilating a little for a long period).
Clock
- Set the clock of the IRT 30 to the correct time (if necessary),
to ensure correct functioning of the clock thermostat (refer to
paragraph 4.3: Setting the clock).
English - 11
English
Operation
Power supply
- The IRT 30 does not use batteries but uses electric power.
- The necessary electric power is supplied via a connection on
the boiler.
- During power failure or when switching off the power supply,
the clock will continue for at least one hour.
- Your clock program will always be maintained.
Maintenance
- Clean the IRT 30 using a dry cloth.
- Do not use any liquid or cleaning agents.This may cause
short-circuiting or damage to the thermostat.
Outside temperature
- If you select the weather dependent regulation (with or
without room temperature compensation), you need an outside
temperature sensor, which is connected to the boiler.
- Without the outside temperature sensor, only the room
temperature controlled regulation can be used.
4.2 Setting the temperature
You can set the temperature in two ways:
1. manually:
- Turn the temperature adjustment knob to the desired
temperature (refer to figure 4-1)
The clock program will be switched off.
2. automatically:
- Turn the temperature adjustment knob counter-clockwise un
-
til the dash points downwards (Auto mode, refer to figure 4-3)
- Raise the temperature by pressing the + key, 0.5
°C per
step, refer to figure 4-3).
- Lower the temperature by pressing the - key.
The clock program will not be switched off, but adjusted
temporarily to your desire. At the next switching point, the
clock program will be activated again.
The display usually shows the measured temperature in the
room and therefore not the set temperature.You can see the
set temperature by pressing the + or – key briefly.The set
temperature will blink for 5 seconds. After that, the measured
room temperature is shown.

If the thermostat is set to weather dependent regulation and you
turn the temperature adjustment knob out
of the AUTO-mode,
the thermostat will function as for weather dependent regulation
with room temperature compensation. On the screen, the symbol
of weather dependent regulation will be replaced by the symbol
for weather dependent regulation with room temperature
compensation (also refer to page 9).
4.3 Setting the clock
For a correct functioning of the clock program, it is important
that the set time is equal to the actual time. Setting the clock is
only possible when the display is in normal mode.
1. Make sure the display is in normal mode (refer to figure 3-2).
Wait 7 seconds until the display returns to the normal mode,
if the display is not in normal mode, for example because you
are programming.
2. Set the correct day:
• Press and hold the DAY key
• Change the day number using the program knob
(Monday = 1,Tuesday = 2 etc.).
• Release the DAY key.
3. Set the correct time:
• Press and hold the TIME key.
• Change the time using the program knob.
• Release the TIME key.
4.4 Clock programs
With the clock programs the IRT 30 can regulate the
temperature automatically throughout the week.The clock
program uses switching points.The program will switch over to
your temperature settings on these points in time.

Switching point
A switching point is a setting in your clock thermostat. It is a point in
time at which you desire another temperature.To set the switching
point, you have to enter the desired time and the desired temperature.
You can check the switching points by slowly turning the program
knob.You will see the day number, time and temperature for each
switching point. Looking to the clock program, you can see a
clock in the left upper corner of the display.As soon as you change
a setting in the clock program, the clock symbol starts blinking.
The IRT 30 is supplied with a standard clock program.
This program looks like this:
This program is activated, when the temperature adjust knob is in
AUTO (refer to figure 4.2).
ECO means the setting of the night temperature (standard set to

Operation
In the standard clock program for the weather dependent
regulation you do not find temperatures, but scale points. One
point of the scale corresponds with a temperature range of
0.5 °C to 2 °C.The calculation starts at 0, which corresponds
with a standard room temperature (20 °C).
Consequently:
– 1 means 18 - 19.5°C and
+ 1 means 20.5 - 22°C.
1 point does not
correspond with 1 °C.
Where setting or changing of the temperature is mentioned
in the text, you must change the scale points for the
weather dependent regulation.This is possible with
steps of 0.5 points.
4.5 Your own clock program
Instead of using the standard clock program, it is also possible to
create your own clock program. In doing so, you can create a
clock program appropriate for your daily schedule. For each
switching point you can adapt the time and the temperature.
Furthermore, you can insert or remove switching points.

interest to some users.
5.1 Mounting
1. Check the contents of the package
The package should contain the following:
- 1 clock thermostat IRT 30 with mounting plate
- 1 bag with 2 screws, 2 washers and 2 plugs
- this manual.
2. Find a suitable mounting position
The thermostat should be mounted to an inside wall at a distance
of approximately 150 cm above the floor. Consider the following
when searching for a suitable mounting position:
- There should be enough air circulation around the thermostat,
but no draught!
- The air temperature should be representative for the whole
room.
- Do not mount the thermostat too near heat sources like
radiators, hot water pipes, tv sets, radios, fire places, lamps or
incoming sunlight.
- Do not mount the thermostat too near cold sources like walls
of unheated rooms, cold water pipes and draught.
- Do not mount the thermostat in a blind corner of the room.
- Mount the thermostat on a flat surface.
3. Install the wiring
Switch off the power supply of the boiler before you install the
wiring!
Install the cable between the boiler and the thermostat. Do not
connect the cable yet!

6.1 Selecting a temperature control
The IRT 30 thermostat is suitable for 3 kinds of temperature
control:
- Room temperature controlled regulation (RR)
- Weather dependent regulation (WD)
- Weather dependent regulation with room temperature
compensation (WD + RTC)
Select one of these control before you continue. Chapter 3
describes the points of attention for making your choice.
You have selected room temperature controlled
regulation (RR)
Set the thermostat as follows:
1. Go the CH menu; refer to paragraph 6.2.
2. Set room temperature controlled regulation.
3. Leave the CH menu.
4. Continue with setting the hot water supply; refer to chapter 7.
You have selected weather dependent regulation
(WD or WD + RTC)

Only change the settings mentioned below!
2. Set weather dependent regulation.
3. Select the correct installation type.
4. Leave the CH menu.
5. Wait for 3 or 4 hours.
Firing characteristic
The firing characteristic is a line which shows the temperature
of the CH water at a certain outside temperature.You can set
the firing characteristic with the help of 2 points:
- the desired water temperature at +20 °C outside
temperature;
starting point
- the desired water temperature at -10 °C outside
temperature;

Setting the temperature control
6. Check the temperature in the coldest room.
7. Set the firing characteristic using the CH menu when the
temperature in the coldest room is too cold or too warm
(refer to paragraph 6.2). For example, if it is too cold or too
warm in a room during winter, the firing characteristic can be
adjusted according to the following diagram.
Outside temperature is less then 0 °C:
Warmer: raise the end point of the firing characteristic
Colder: lower the end point of the firing characteristic
Outside temperature is between 0 °C and 10 °C:
Warmer: raise the starting point as well as the end point of the
firing characteristic
Colder: lower the starting point as well as the end point of
the firing characteristic
Outside temperature is above 10 °C:
Warmer: raise the starting point of the firing characteristic
Colder: lower the starting point of the firing characteristic
8. Continue setting the hot water supply; refer to chapter 7.
If floor heating is used, we recommend to reduce the maxi-
mum temperature of the CH water.This can be obtained with
the UBA of the boiler. Reducing the maximum temperature of
the CH water prevents too hot water in the floor heating.

If the advanced heat-up is set to off, the boiler
starts heating at the moment when the clock
program switches over from a low temperature
setting to a higher temperature setting.
If the advanced heat-up is set to on, the
thermostat takes care that the boiler starts
heating earlier, so that the desired temperature is
reached at the switching point of the thermostat.
The thermostat learns in the long term how
much earlier the boiler must start heating.
Standard, the advanced heat-up is set to on
(yes = 1).
Kind of temperature regulation
The kind of temperature regulation which is
selected.
The set regulation can be recognised by the

To each type of installation, a special firing
characteristic is attached (starting point, end
point, room influence); refer to table 6-1.
Starting point
The desired CH water temperature at +20 °C.
This is called the starting point of the firing
characteristic.
End point
The desired CH water temperature at -10 °C.
This is called the end point of the firing
characteristic.

Setting the hot water supply
7. Setting the hot water supply
This chapter is only necessary if the boiler also supplies hot
water.
If the hot water supply is set to automatic (refer to chapter 4),
the thermostat takes care that the water in the boiler will only
be heated during the day. With the ‘advanced hot water heat-up’
and the ‘hot water stop delay’, the start and stop points for
heating the water can be set:
- The advanced hot water heat-up determines how long before
the switching point from ECO to another temperature in the
clock program the boiler starts heating the boiler water.
- The hot water stop delay determines how long after the
switching point to ECO in the clock program, the boiler stops
heating the boiler water.
If advanced heat-up is set to on (refer to chapter 6), the
advanced hot water heat-up starts heating the hot water,
calculated from the moment, the CH installation starts
advanced heating up the house.
7.1 Checking and/ or changing the settings
- Check with the hot water menu (refer to paragraph 7.2)
whether the advanced hot water heat-up is set correctly.
Change the advanced hot water heat-up if necessary.
- Check with the hot water menu whether the hot water stop
delay is set correctly. Change the hot water stop delay if necessary.
- Leave the hot water menu.
The IRT 30 thermostat is now ready for use.

Configuration and calibration of the IRT 30 thermostat
8. Configuration and calibration of the
IRT 30 thermostat
This chapter is intended for the installer.
Configuration and calibration of the IRT 30 thermostat are
only necessary in exceptional situations.
8.1 Adapting the configuration
The IRT 30 thermostat can be adapted, with a few settings, to the
speed and the capacity of the CH installation.These settings are
included in the configuration menu. In this menu you can:
1. Change the heat-up speed setting (PID).
2. Adjust the clock speed.
3. Switching the slow temperature rise on or off.
4. Reset the thermostat.
The configuration menu appears in the display when you first
press and hold the MENU key and the INSERT key and after
that, press and hold the REMOVE key. You now press and hold
3 keys at the same time.
You can scroll through the configuration menu by pressing only
the INSERT key.
1. Change the heat-up speed (PID) setting
If the thermostat is set to room temperature controlled
regulation, you can adapt the heat-up speed of the CH
installation.This is necessary if the temperature in the room
where the thermostat is fitted, during heat-up, rises to a higher
temperature then the set temperature and then drops to the set
temperature.
There are 3 possible settings:
- PID 1:This is the standard and also the fastest setting.This
setting satisfies almost all of the cases.
- PID 2: This is a slower setting.This setting is intended for a
‘fast’ house, that means a CH installation with a large boiler
and radiators with a large surface.
- PID 3: This is the slowest setting.This setting is meant for very
fast houses.
34 - English
English
Configuration and calibration of the IRT 30 thermostat
You can adapt the heat-up speed as follows:
1. Simultaneously press the MENU, INSERT and REMOVE key.
PID appears on the display.
2. Hold the INSERT key and release the other keys.
3. Turn the program knob, while holding the INSERT key, until
the desired PID number appears in the display.
4. Release the INSERT key.
2. Adjust the clock speed.
The IRT 30 thermostat has a internal clock.This clock can lose or
gain some time in the long term. You can adjust the speed of the
clock.When you enter a correction of ‘+1’, the clock will run
1 minute per year faster.
You can adjust the clock as follows:
1. Simultaneously press the MENU, INSERT and REMOVE key,
and release them.
2. Press an hold the INSERT key again. On the display, ëcorrí
appears.
3. Turn the program knob, while holding the INSERT key, until
the desired clock correction appears.
4. Release the INSERT key.
3. Switching the slow temperature rise on or off.
If you have a boiler with a high capacity, this can cause the CH
water to heat up too fast.This can result in a ticking sound in the
tubes.To prevent this, you can set the slow temperature rise to on.

again (refer to paragraph 5.2).
You can reset the thermostat as follows:
1. Simultaneously press the MENU, INSERT and REMOVE key,
and release them.
2. Again press the INSERT key three times and hold it. On the
display, tESt appears.
3. Release the INSERT key.
8.2 Calibration
Although the sensors of the IRT 30 thermostat are of high-
quality, some irregularities can not be avoided in the long term.
You can recalibrate the sensors then. Only recalibrate the sensors
when the measurement deviation becomes clearly evident and
irritating.
Incorrect calibration may have serious consequences to the
operation of the thermostat. Preferably, let the installer
recalibrate the thermostat during a service visit.

Configuration and calibration of the IRT 30 thermostat
Calibration of the temperature sensor of the thermostat
The temperature sensor in the IRT 30 thermostat should be
calibrated when the measured temperature, shown on the display,
deviates from the actual temperature.
It is no simple task to determine the actual temperature in
the room.The position you are measuring and the accuracy of
the thermometer you are using may influence the result. It is
also important to measure the temperature when the tempe-
rature is stable, (i.e. not during the heat-up periods etc.).
You can recalibrate the temperature sensor as follows:
1. Make sure the display is in normal mode (refer to figure 3-2).
2. Press and hold the MENU and then REMOVE key. Hold both
keys. In the middle of the display, the temperature which is
measured by the sensor in the thermostat is shown. On the
right side, a blinking temperature, which you can alter, is
shown.
3. Turn the program knob, while holding the MENU and
REMOVE keys, until the blinking temperature indicates the
actual temperature.
4. Release all keys when you are finished.
Calibration of the temperature adjustment knob
Calibration of the temperature adjustment knob of the
thermostat may be necessary when the actual temperature
deviates from the temperature which is set manually with the
temperature adjustment knob. For example, the temperature
adjustment knob is set to 20 °C but in the long term the actual
temperature never rises above 19 °C.
You can calibrate the temperature adjustment knob as follows:
1. Make sure the display is in normal mode (refer to figure 3-2).
2. Simultaneously press the MENU and REMOVE keys twice and
hold them.To the right on the display, the TEMP symbol appears.

temperature onto which the temperature adjustment knob is
set.
5. Release all keys when you are finished.
Calibration of the outside temperature sensor
The outside temperature sensor should be calibrated when the
measured temperature shown on the display, deviates from the
actual outside temperature at the outside temperature sensor.
Note: The outside temperature sensor can only be calibrated when it
is connected to the boiler, and the weather dependent
regulation (WD or WD + RTC) has been set.

Malfunctions and the display codes of the boiler
9. Malfunctions and the display codes of the
boiler
In this chapter, some possible problems/malfunctions will be
described. Furthermore, the possible solutions will be given.You
can always contact your installer if the problems persist.
For some items, the solution depends on the set kind of
regulation.This will be reflected by the following abbreviations:
- RR = room temperature controlled regulation
- WD = weather dependent regulation
- WD + RTC = weather dependent regulation with room
temperature compensation
9.1 Malfunctions
During heat-up, an annoying ticking sound is heard in the
pipes.
At the beginning of the day, the water will be heated-up as quickly
as possible, to enable the radiators to warm up the rooms as
quickly as possible.The metal tubes will expand because of the
sudden temperature rise, which may result in a ticking sound.
1. Increase the PID setting to reduce the heat-up speed of the
installation
2. Set ‘slow temperature rise’ to ON.
3. If the capacity of the boiler is much higher then necessary, the
water will be heated-up too fast. By means of the partial load
potentiometer on the UBA, the maximum capacity for heating
up the water can be reduced, so that the water will be heated
up more slowly.
4. If the rooms have been equipped with too many or too large
radiators, the house can also be heated with water of a lower
temperature.The maximum temperature setting of the water
can be reduced on the UBA.
In the morning, heating up takes too long
1. Set the ‘advanced heat-up’ to on
(only for RR and WD + RTC).
2. Advance the switching point to give the installation more time
to heat up the house.
3. We advise not to let the difference between the day and night
temperature exceed 5 °C (for floor heating we advise a
maximum difference of 2 °C).
English - 39
English
Malfunctions and the display codes of the boiler
At the beginning of the day, the installation is heated up
too far, too long.The rooms become too warm.
1. Lower the temperature in the clock program, for the
switching point of the beginning of the day.
2. Raise the PID setting, so that the installation will burn less
intensely.
3. If the capacity of the boiler is much higher then necessary, the
water will be heated up too fast. By means of the partial load
potentiometer on the UBA, the maximum capacity for heating
up the water can be reduced, so that the water will be heated
up more slowly.
4. If the rooms have been equipped with too many or too large
radiators, the house can also be heated with water of a lower
temperature.The maximum temperature setting of the water
can be reduced on the UBA.
The room becomes too warm (warmer then the set
temperature).
1. Is the IRT 30 thermostat able to measure the correct
temperature (only for RR and WD + RTC)? Is the IRT 30
thermostat installed on a cold outside wall or in stream of
draught?
2. If the rooms have been equipped with too many or too large
radiators, the house can also be heated with water of a lower
temperature.The maximum temperature setting of the water
can be reduced on the UBA.
3. Are the thermostatic radiator valves installed correctly?
(Is cold air streaming around the thermostatic radiator valves)?
It is too cold (colder then the set temperature) in the
room.
1. Is the IRT 30 thermostat able to measure the correct
temperature (only for RR and WD + RTC)? Is the IRT 30
thermostat installed between cupboards (no natural airflow)
or in the vicinity of heat sources (tv, refrigerator, radiator,
etc.)?
2. Are the thermostatic radiator valves completely open in the
room where the thermostat has been installed?
3. Check the setting of the maximum CH water temperature on
the UBA (90 °C maximum).
4. Has the pump switch on the UBA been set to position 2 (only
for WD and WD + RTC)?
40 - English
English
Malfunctions and the display codes of the boiler
Energy consumption is too high (higher then old boiler) /
the boiler burns too often or too long.
1. Is the room heated while it is not in use?
Insert more switching points with a lower temperature to the
clock thermostat.
2. Is the capacity of the new boiler higher then the capacity of
the old boiler?
3. Have you replaced an old geyser by a combi boiler? A combi
boiler can produce more hot water (more comfort) but also
uses more energy.
4. Is the ECO setting too high, as a result of which the room
temperature is too high during the night?
5. (Only WD and WD + RTC) Are the values for the starting
point and end point set in the CV menu not set too high?
The display shows an incorrect temperature
1. Is the IRT 30 thermostat able to determine the correct
temperature? Is the thermostat installed on a cold or warm
wall? Is it installed in direct sunlight or in draught? Is the IRT
30 thermostat installed near an open window or near heat
sources (tv, refrigerator or lamps)?
2. If you are convinced that the indication of the temperature is
incorrect (most of the times it is correct!), the temperature
measurement can be calibrated (refer to chapter 8).
Outside temperature indication is incorrect (only for WD
and WD + RTC) /display shows --- on the position of the
temperature indication
1. Is the outside temperature sensor able to determine the
correct outside temperature? Installed on a warm or cold
spot on the outside wall, (influenced by sun, wind, snow, ice or
rain)?
2. Has the correct wiring (preferably 0.75 mm
2
) been used. Does
the wiring run along a 230 V power supply cable?
3. Is the wiring connected to terminal 7 and 8 of the terminal
block in the boiler?
4. If necessary, the outside temperature sensor can be calibrated
(refer to chapter 8).

2. (only for WD and WD + RTC) Has the correct wiring
(preferably 0.75 mm
2
), for connection of the outside
temperature sensor, been used. Does the wiring run along a
230 V power supply cable?
3. Is the cable defective? You can check this by connecting the
IRT 30 thermostat directly to terminal 3 and 4 of the boiler,
using a short cable.
9.2 Boiler display codes
When you press the HEATING key, a boiler display code appears
in the display for 3 seconds.This code is shown on the position
of the temperature indication. A boiler display code consists of
two symbols:
- The first symbol indicates the current function of the boiler,
- the second symbol indicates which part of the function is
active, or in some cases, is not active.
In case of a malfunction, the display shows the symbol of a
mechanic (refer to figure 9-1). Press the reset button on the
boiler when an error code appears on the display of the
thermostat.
If the malfunction keeps repeating, you should contact
your installer.

Malfunctions and the display codes of the boiler
Other codes:
- Malfunction of the sensors.
On the display appears:
- the symbol of the mechanic
- three blinking dashes (on the position of the temperature
indication).
- the symbol of the room temperature, or the symbol of the
outside temperature, indicating which sensor is
malfunctioning (refer to figure 9-2 and 9-3).
figure 9-2 Room temperature sensor
figure 9-3 Outside temperature sensor
- Malfunction of the communication with the UBA
On the display appears:
- the symbol of the mechanic
- blinking text: UbA (refer to figure 9-4).

Switching point
A switching point is a setting in your clock thermostat. It is a
moment in time at which you desire a different temperature.
To set this, you have to enter the desired time and the desired
temperature.
Reference room
A reference room is a room (for example the living room) where
a temperature can be measured which is representative for the
entire house.
We assume, that the temperature in other rooms (for example
kitchen or bedroom) is equal to the temperature in the reference
room.
A room where the temperature is not representative for the
house, due to open windows or the use of a fire place, is not
suitable as a reference room.
An other reason to appoint a specific room as reference room is
that most of the time will be spent in this room.Therefore, it is
important that the temperature regulation of this room is correct.
The other rooms in the house can have a lower (or higher)
temperature.
Room temperature controlled regulation
This is one of the principles of regulating the temperature in your
house. According to this regulation, the thermostat measures the
temperature in the room where it is fitted.This measured
temperature will be compared with the set (desired)
temperature.The thermostat now determines how intensely the
boiler must burn to reach or maintain the desired temperature.
Weather dependent (temperature) regulation
This is a principle of regulation in which the determination of the
CH water temperature (and the intensity of burning of the boiler)
is achieved by the outside temperature and a number of preset
values in the IRT 30.With this, the desired temperature will be
reached as close as possible.You can influence the temperature in
the rooms by using radiators with thermostatic radiator valves.

Glossary
Weather dependent (temperature) regulation with room
temperature compensation
This is one of the ways to regulate the temperature in your
house.With this principle, the CH water temperature (and the
intensity of burning of the boiler) is determined, in the first
instance, by the outside temperature and the preset values on the
IRT 30. However, the thermostat also measures the temperature
in the room where it is fitted.The temperature in the room
where the thermostat is fitted is determined by the thermostat
itself.This measured temperature is compared with the set
(desired) temperature.The thermostat can now correct the
preset values to ensure the desired temperature can actually be
reached or maintained.
Firing characteristic
The firing characteristic is a line which shows the temperature of
the CH water at a certain outside temperature.You can set the
firing characteristic with the help of 2 points:
- the desired water temperature at +20 °C outside temperature;
starting point.
- the desired water temperature at -10 °C outside temperature;
end point.
