INSTALLATION

SAFETY INSTRUCTIONS

Electrical equipment must only be installed and assembled by expert

personnel.

Before connecting the programmable thermostat, ensure that all associated

utilities (pumps, valves, boiler etc.) are not connected to the supply and that

the load is within the ratings marked on the thermostat.

LOCATION

Install the programmable thermostat approximately 1.5 m above the floor,

and away from sources of heat (radiators, sunlight, cookers) and from doors

and windows.

CLEANING

Clean with a damp cloth only.

IMPORTANT

Do not overtighten the screws when installing, as this may warp the base

and compromise the functions of the touch screen.

CONNECTION DIAGRAM

Fit the batteries in the compartment, ensuring that the polarities are correct

as indicated.

IMPORTANT

- Fitting the batteries with the wrong polarity may damage the

programmable thermostat

- If battery charge drops below the minimum permissible level, the

programmable thermostat switches to OFF state and the relay contact

opens

- Remove the batteries if the programmable thermostat is not used for a

prolonged period of time

The programmable thermostat has the following three different low battery

warning modes:

- Low battery icon displayed STEADY: the functionality of the

programmable thermostat will soon be compromised

- Low battery icon

FLASHING: programmable thermostat requires

imminent battery replacement

- Messages flashing in alternation, programmable thermostat

switches to OFF state and the relay contact opens

NOTE

The correct date and time settings are maintained if the batteries are removed

and replaced within one minute with the low battery icon displaying STEADY.

6 - LOCK FUNCTION (with PIN)

This menu option may be used to enable a LOCK function protected by a

numerical access code to prevent tampering (see page 12).

From the advanced menu, press

repeatedly to view the following

screen:

To set the display lock only, set 000 as the PIN with the and keys.

NOTE

Enter the emergency unlock code 513 if you have forgotten the PIN.

After unlocking the unit with the emergency unlock code 513, it is strongly

recommended to access the advanced menu and check and/or modify the

user-defined PIN set previously.

7 - ENERGY SAVING E1

When the Energy Saving E1(ECO1) function is active, the thermostat

automatically optimises the operation of the system - specifically, using an

internal mathematical algorithm to compensate for inertia and adjust

activation intervals and temperature settings appropriately to improve

perceived comfort. This function also significantly reduces energy

consumption. Once in the advanced menu, press

repeatedly to reach

the E1 function. Use the and buttons to select the following values

as desired.

E1 = 0 Function off

E1 = 1 Function on

E1 = 2 Function on if heating system is equipped with zone selector

valves with opening times greater than 10 seconds and less than

90 seconds

NOTE

This function is not recommended for forced ventilation heating systems

(e.g. fan coil).

8 - ENERGY SAVING E2

With the Energy Saving E2 (ECO2) function active, the thermostat determines

how long it takes the ambient air to reach the desired temperature.

This entirely automatic function adjusts the activation intervals, anticipating

and shortening activation times as necessary to save energy.

If activation times were set manually, in some cases it may be necessary to

anticipate/shorten activation times significantly to reach the desired

temperature at the desired time.

This function also takes the season, insulation and heat losses into account,

adjusting and shortening activation times accordingly. Example. If it takes

1.5 hours to increase the temperature by 4°C in January but only 40 minutes

in March, the ECO2 function will take this time into account.

ENERGY SAVING

NOTE

When the thermostat is automatically anticipating/shortening activation

times (relative to the programmed hour period), the symbol is displayed

in the main menu.

NOTE

When the E2 function is activated, the thermostat takes a few days to

monitor ambient conditions before the function is fully effective.

9 - DELAYED START

This function is used to delay start by 30 minutes after the programmed hour

period.

The following screen is displayed after the ENERGY SAVING E2 menu:

Press one of the two arrow keys to enable the function, and press

to confirm.

To exit the advanced menu, press

repeatedly or press

until the

unit sounds three beeps confirming that the modification has been saved.

The thermostat is now off.

Press to switch the thermostat on, and configure the settings as

indicated on page 22.

10 - RESET

Used to restore all the original factory settings.

Use the and keys to set .

Press

to confirm. The thermostat switches off completely and then

restarts, displaying the software version and then the main screen.

The unit has now been reset and all factory settings have been restored.

NOTE

Resetting does not cancel the time and date.
