5.1 Change temperature setting

Wake-up the thermostat by pressing any key.

Press or , to change the temperature set point (digits starts to blink).

By pressing validation key , temperature set point value is validated.

5.1.1 Boost/Timer mode

In mode boost, set point temperature is applied during a selected time.

After this time, thermostat will return to former mode.

You can first adjust, the desired setting temperature with or , press validation key

, to validate, default value 24°C.

In a second time, you can adjust the du- ration in hours “H” if below 24H, then in day “d”.

With automatic H&C switching configuration, boost/timer mode can’t be selected.

If configuration system is changed by H&C signal, boost/timer mode will be stopped.

Thermostat will return to the previous selected mode.

Default value: “no” (0 minute)

Value range: 1h to 23 hours (step of 1 hour) and 1 day to 44 days (step 1 day).

5.1.2 Comfort mode

In this mode, comfort temperature set point will be followed all the time.

This mode can’t be selected if thermostat is a “slave” product and H&C signal sends

reduced information.

5.1.3 Reduced / ECO mode

In this mode, reduced temperature set point will be followed all the time.

This set point corresponds to comfort set point reduced by an offset (see paragraph 7.2

“User parameter description”).

Reduced/ECO mode is available if if thermostat is in master configuration;

If H&C signal is in ECO mode and the thermostat is configured in slave, the thermostat is

set automaticaly in ECO configuration

Note: In cooling mode, reduced mode acts like the OFF mode (system is stopped, NC

actuators are closed).

Thermostat is in master configuration when logo mode is .

Thermostat is in slave configuration when logo is without the frame .

Important notes:

- With “Floor Limit” regulation, Reduced/ ECO mode couldn’t work properly if “Low limit”

value is too high;

- If system configuration is automatic H&C switching and thermostat is system master,

user can’t set derogation.

- If configuration system is changed by H&C signal, setpoint derogation will be stopped.

5.1.4 Anti-freeze mode

Use this mode if you want to protect your installation against freezing. (default value 7°C).

Remark: in cooling mode, Anti-freeze mode acts like the OFF mode (system is stopped).

If “floor limit” regulation is set by user/ installer, selecting anti-freeze mode stops “floor

limit regulation”.

Antifreeze temperature setpoint is applied when opened window is detected.

5.1.5 OFF mode

Use this mode if you need to switch off your installation.

Be Careful: In this mode your installation can freeze.

- With off mode, “floor limit” regulation is stopped.

5.1.6 Reversible mode

This mode allow to switch between the heating and cooling system, the changeover can

be managed by the thermostat in Master mode (manual or automatic) displayed in Slave

mode (H&C signal at the thermostat input).
