2 Product information
2.1 Product description
The programming unit makes it easy to operate your Buderus heating system with Energy
Management System (EMS). For example, simply pressing one key starts DHW heating at any time;
alternatively, using the rotary selector can change the room temperature in the entire home. The
thermostatic radiator valves only need to be adjusted if an individual room is too cold or too hot.
The automatic control with the adjustable switching program ensure energy efficient operation by
reducing the room temperature at certain times or by shutting down the entire heating system
(adjustable night setback).
The heating system is controlled in such a way that you benefit from optimum heating comfort and
minimum energy consumption.
2.2 Correct use
The programming unit must only be used to operate and control Buderus heating systems in

4.4 Selecting a heating circuit
What is a heating circuit?
A heating circuit describes the circuit taken by the heating water from the boiler to the radiators and
back again. Multiple heating circuits can be connected to one boiler; for example, one heating circuit
for radiators and another heating circuit for underfloor heating. The radiators are supplied with a
higher flow temperature than the underfloor heating system. The flow temperature is the temperature
of the heating water generated by the boiler as it flows into the heating circuit.
The programming unit can be tied into the Energy Management System (EMS) by two different
methods:
• As the only programming unit in the system (factory setting): the programming unit is installed in
the living space or on the boiler.
Example: detached house with one heating circuit. If DHW is to be controlled, an RC35
programming unit will be needed to comply with part L.
• As a remote control for one heating circuit:
1)
The RC25 programming unit is operated in unison with a higher programming unit (e.g. RC35).
The RC35 programming unit is installed either in the living space or on the boiler, and regulates
one heating circuit (e.g. for the main apartment). The RC25 programming unit captures the room
temperature in a separate living area and regulates this second heating circuit. Basic settings for
the heating system are made at the RC35. Consequently, these settings become available for
the heating circuit with the RC25 programming unit.
Examples: underfloor heating on one floor, radiators on another; or a flat together with a separate
living area or clinic.
1) Not available on boilers with UBA.

Fig. 2 Options for a heating system with one or two heating circuits
1 One programming unit controls one heating circuit. (Must be used in conjunction with RC35 to comply
with part L).
2 Each heating circuit has its own programming unit / remote control unit.
4.5 Shutting down/switching off
The RC35 programming unit is powered via the heating system and remains permanently on.
The heating system is only switched off for maintenance work, for example.
B To start up and shut down the heating system: set the ON/OFF switch on the boiler programming
unit to 1 (ON) or 0 (OFF).
After shutting down or in the event of a power failure, the time and day are retained for
several hours. All other settings are retained permanently.

5 Function control
This chapter describes how you can change the room and DHW temperatures. You control these
functions by pressing a key on the r.h. side or behind the programming unit flap, or by turning the
rotary selector.
5.1 Selecting the operating mode
You may operate the programming unit in two different ways:
• In automatic mode
• In manual mode
You can activate the operating mode directly by pressing the specified key.
Operating mode Key Explanation
Automatic
(recommended setting)
The switching program is active. The system will
change over automatically between day mode and night
mode at the set time (switching point).
1)
At night the
heating system will operate at a reduced room
temperature (factory setting; night shutdown is also
possible).
DHW heating is on during the day and off at night
(factory setting).
The LED for the automatic key illuminates, along with
the LED for either day or night mode, depending on
which is currently active.

Manual daytime operation
Continuous heating
Factory setting: 21 °C.
Manual day mode is useful if you want to heat outside
the usual times. Automatic mode is switched off.
DHW heating is on (factory setting).
Only the day mode LED illuminates.
Manual nighttime operation
Permanently reduced
Factory setting: 17 °C.
The heating system operates with a reduced room
temperature (factory setting). Manual night mode is
useful if you are occasionally absent for long periods.
Automatic mode is switched off.
DHW heating is off (factory setting).
Only the night mode LED illuminates.
1) The automatic day and night modes correspond to the manual day and night modes. The only difference lies
in the automatic changeover.
If the heating system operates under weather-compensated control (Æ Chapter 6.1,
page 25): during spring and autumn, you may feel that your home is too cold, even
though your heating system is in summer mode on account of the outside temperature
(only DHW heating). In that case, select manual mode to heat on an hourly basis.

5.2 Setting the room temperature
Generally, you can adjust the room temperature using the rotary selector. This can be done in three
different ways:
• Changing the room temperature temporarily. The modified settings are retained until the heating
system changes into a different operating mode (e.g. night mode).
• Changing the room temperature for the current operating mode (e.g. automatic day mode). The
modified setting applies to automatic day mode from then onwards.
• Changing the room temperature for an operating mode that is not currently selected (e.g.
changing the night room temperature during the day). The modified setting applies to this
operating mode from then onwards.
NOTICE: System damage due to frost!
If room temperatures are set below 10 °C, rooms may cool down so much that pipes in
external walls (for example) may freeze in cold weather.
B Set room temperatures higher than 10 °C.
The actual room temperature is shown as the permanent display. Your heating
contractor can also set a different permanent display.

5.3 Setting DHW functions
Risk of scalding from DHW temperatures over 60 °C!
The programming unit also offers you the option of heating DHW in an energy-conscious manner.
The setting is subject to how the programming unit was installed (Æ Chapter 6.1, page 25):
• If the RC25 programming unit operates as the only programming unit in the system, DHW
heating commences automatically 30 minutes prior to the start of day mode of the heating
program. DHW is not produced during night mode. In day mode, the DHW circulation pump is
started twice per hour for three minutes to safeguard the constant supply of taps with hot water.
1)
The DHW temperature can be set to a maximum of 60 °C (= factory setting). For UK an RC35
must be used for DHW control to comply with part L.
• If the RC25 programming unit is installed as a remote control for one heating circuit,
2)
then DHW
heating and the operation of the DHW circulation pump will be set for the entire heating system
with the higher programming unit (e.g. RC30/RC35). The set DHW temperature can be changed
with the RC30/RC35 or the RC25 programming units; however, the setting range of the RC30/
RC35 programming units applies (maximum 80 °C).
5.3.1 Checking or changing the DHW temperature
Initial situation: the flap is closed.
WARNING: Risk of scalding!
The factory setting for the DHW temperature is 60 °C. There is a risk of scalding at the
hot water draw-off points if the temperature is set higher than this and also following
thermal disinfection.
B If the temperature set is higher than 60 °C or following thermal disinfection, never
open any hot water tap without mixing in cold water as well.
1) Function dependent on the boiler used.
2) Function not available on boilers with UBA.
Operation Result
1. Hold down and simultaneously turn rotary selector .
The value can be changed.
2. When you have reached the required DHW temperature,
release the rotary selector.
The modified temperature is saved.
The standard display appears again.

5.3.2 Heating DHW only once
1)
To save energy, during day mode DHW is only reheated automatically when its temperature falls
5 °C below the set DHW temperature.
If you need large amounts of hot water one evening or outside the set times for day mode, you can
heat up the DHW.
Initial situation: the flap is closed.
1) Function not available on boilers with UBA.
Operation
1. The LED of key illuminates if the DHW temperature falls below the set value. To heat
up the DHW manually:
press .
The LED at key flashes. Heat-up starts, and is later terminated automatically.
2. If you want to stop the heating process, press again.
Subject to the size of the DHW cylinder and the boiler output, DHW will be available
after approx. 10 – 30 minutes. With instantaneous water heaters or combi boilers,
DHW is available almost immediately.

5.5 Heating program selection
Automatic mode ensures automatic changeover between day and night mode at defined times.
The factory settings means 21 °C or 17 °C are set for day or night mode.
Before you select a heating program, consider the following:
• At what time in the morning should your home be warm? Is this time also subject to the day of
the week?
• Are there days when you don't want to heat during the day?
• From what time in the evening do you no longer need to heat? This may also depend on the day
of the week.
If the RC25 programming unit is installed as a remote control unit in conjunction with an RC30/
RC35 programming unit, heating programs from the RC30/RC35 can be used by the RC25
programming unit (so-called “Own programs”, Æ Tab. 5, page 24).
The programming unit has eight different, preset heating programs. See the following Tab. 5,
page 24 for a summary of the times of these preset heating programs.
Please check which heating program best meets your requirements to optimise heating comfort and
energy efficiency. Primarily check the number and times of the switching points for day and night
mode. Program Pr1 (“family” program) is preset at the factory.
Operation Result
1. Open flap.
2. Hold down . The currently selected heating program is
displayed.
3. Select the required heating program using rotary selector
(Æ Tab. 5, page 24).
4. Release . The selected program is saved.
The permanent display will then appear again.
The selected heating program will only be effective if automatic mode has been selected
(Æ Chapter 5.1, page 15).

6 Information on setting the programming unit
6.1 Types of control
The heating system can be operated in three control modes. Depending on your requirements, your
heating contractor will select and set up one of these options:
Room temperature control
With this control mode, the programming unit must be fitted in a room that is fairly typical for the
home. The programming unit records the room temperature in this “reference room”. Control of the
flow temperature is determined by the set room temperature and the actual room temperature.
Consequently external temperature influences in the reference room (e.g. open windows, sunlight
or heat from a fireplace) will affect your entire home.
Set the room temperature of your home or reference room at the programming unit. You can
produce higher or lower temperatures in the other rooms by adjusting the thermostatic radiator
valves.
Weather-compensated control
The temperature of the heating water in the boiler is defined by the heating curve. You can select
whether this heating curve will be influenced solely by the outside temperature, or whether the
temperature in the reference room should also have an influence.
• Purely weather-compensated control:
The outside temperature is captured by a temperature sensor. The flow temperature is calculated
solely on the basis of the outside temperature in accordance with the set heating curve.
You can set the room temperature for the entire home at the programming unit (which will shift
the heating curve up or down). You must adjust the thermostatic radiator valves in every room in
order to achieve the required room temperature.
• Weather-compensated control with room temperature hook-up:
With this control mode the flow temperature is primarily determined by the outside temperature,
but is also influenced by the room temperature to the extent selected by your heating contractor.
The following applies to room temperature control and for weather-compensated
control with room temperature hook-up:
The thermostatic radiator valves in the “Reference room” (the room where the
programming unit is installed) must be fully open! Control of the flow temperature is
determined by the room temperature recorded there. It must not be limited by closed
thermostatic valves.

6.2 Tips for energy efficiency
• You can save around 6 % on your heating costs by reducing the daytime
room temperature by 1 °C.
• Only heat if you need warmth. Use the switching programs for automatic
night setback.
• Air your home wisely: leave the windows wide open for a few minutes
rather than leaving them slightly open all the time.
• Close the thermostatic radiator valves while airing rooms.
• Make sure that your windows and doors form a proper seal.
• Never position large objects such as a sofa immediately in front of radiators (maintain a clearance
of at least 50 cm). Otherwise, the heated air cannot circulate and heat the room adequately.
• You can also increase the energy efficiency of your DHW heating: compare the times when you
want your rooms to be warm with the times when you need hot water. It may be practical to use
a separate switching program for DHW heating.
• Arrange for your heating contractor to service your heating system annually.

8 Troubleshooting
This chapter deals with frequently asked questions about your heating system. This will in many
cases enable you to eliminate suspected faults. At the end of the chapter you will find a table listing
faults and corresponding remedies.
8.1 Frequently asked questions
Why do I set a room temperature, even though it is not recorded?
When you set the room temperature – even if it is not recorded, as with weather-compensated
control – you are changing the heating curve. This changes the room temperature, because the
temperature of the heating water changes and with it the temperature of the radiators.
Why does the room temperature measured with a separate thermometer not correlate
with the set room temperature?
The room temperature is influenced by a number of different variables. If the RC25 programming
unit is installed on a cold wall, it will be influenced by the cold temperature of the wall. It will be
influenced by the heat from a fireplace or chimney, for example, if it is installed in a warm part of the
room. Therefore, a separate thermometer can indicate a different room temperature than that set at
the RC25 programming unit. To compare the actual room temperature with the values measured by
another thermometer, the following is important:
• The separate thermometer and the room controller must be physically close to each other.
• The separate thermometer must be accurate.
• When comparing, do not measure the room temperature when the heating system is heating up,
as the two devices may react at different speeds to the change in temperature.
If you have followed these instructions and you can still detect a discrepancy, you can calibrate the
room temperature display (Æ page 17).
Why do the radiators get too hot when the outside temperature is relatively high?
If you have a heating system with one heating circuit and no mixing valve (heating circuit 1), this is
normal. The pump only starts up when the boiler reaches a predefined flow temperature. If the flow
temperature is higher than required based on the outside temperature, the radiators may get hotter
for a short time. The heating control unit detects this and responds accordingly after a short time.
Do not adjust the thermostatic valves on the radiators and wait until the set room temperature is
reached. Even in summer mode, radiators may be heated briefly under specific circumstances:
namely when the pump is started up automatically at a predefined interval to prevent it from “seizing
up” (jamming). If the pump happens to start immediately after DHW heating, the unusable residual
heat is dissipated via the heating circuit and the radiators.

Why does the pump run at night, even though the home is not being heated at all or only
very little?
This depends on the setting chosen by your heating contractor for night setback.
• Reduced operation: The pump still runs even if the home is only being heated a little to achieve
a low room temperature.
• Shutdown mode: The heating system (and therefore also the pump) is automatically shut down
in night mode. If the outside temperature falls below the frost protection temperature, the pump
is automatically switched on by the “Frost protection” function.
• Shutdown mode and Room setback mode: The heating system is switched on automatically
when the captured temperature falls below the set value. The pump will then also start.
The actual room temperature is higher than the set room temperature. Why is the boiler
still running?
The boiler may be running to heat up DHW. Your heating system can be set to three possible control
modes (Æ page 25):
• Room temperature control: The boiler shuts down when the set room temperature has been
reached.
• Weather-compensated control: The heating system runs on the basis of the outside temperature.
• Weather-compensated control with room temperature hook-up: The heating system takes
advantage of both the above control modes.
The boiler can still operate in the latter two cases, even if the captured room temperature is higher
than the set room temperature.

8.2 Fault and service displays
The programming unit makes a distinction between three types of messages:
• Service message
• Fault message (= system fault; incorrect settings on the programming unit, or component faulty)
• Service messages (indicating that some maintenance work is required)
“Code” column in Tab. 6
The messages are identified by codes. These inform your heating contractor about the possible
cause.
The codes are issued in two parts. The first indicates the service code (display code) (e.g. A01).
Turning the rotary selector clockwise displays the fault code (e.g. 816).
By means of the service code, the display indicates, whether a Fault Condition (= system fault) or
service message is currently active.
1. In case of a fault message, turn rotary selector clockwise.
The fault code will be displayed.
2. Check whether you can eliminate the fault yourself with a reset (Æ Chapter 8.3) or by means of
the explanations in Tab. 6.
3. Otherwise notify your heating contractor immediately (stating the code).
4. In case of a service message, check whether the message can be cleared with the aid of the
explanations in Tab. 6.
5. Otherwise notify your heating contractor immediately (stating the code).
NOTICE: System damage due to frost!
The heating system can freeze up if it has been switched off through a fault shutdown.
B Try and clear the fault.
B If that is not possible, notify your heating contractor immediately.
The faults depend on the boiler used. Information about the faults can be found in the
boiler documentation.
