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).

Calibration of internal room sensor (remote)
This menu is only displayed if parameter rEG (#20) is set with
“Air” or “Fll”.
Calibration must be done after a given order has been
operating for a day. Place the thermometer in the middle
of the room at about 1.5 m above the floor. Record the
temperature shown after 1 hour. When you enter calibration
mode, displaying of logo means no calibration has been
performed yet. Enter the reading on your thermometer using
minus and plus keys (step of 0.1°C).
The setting is validated with validation key. logo
appears to indicate that calibration.
If user press simultaneously minus and plus keys,

Important note: a large temperature deviation may indicate an
inappropriate installation of the thermostat. If the temperature
difference is too big, this could mean your thermostat was not
installed properly e.g. in the right place.

9. Temperature sensors used for regulation
9.1 Temperature sensors
Thermostat can measure temperature from two different sensors:
-
Internal sensor: this sensor is embedded on thermostat.
-
External sensor: This sensor is plugged at the back of thermostat. It can be used as
“ambient” temperature sensor or as floor temperature sensor depending of regulation
configuration.
9.2 Description of regulation configurations
Heating and cooling regulation can use two different temperature sensor. With respect
of external sensor connection, installer can choose a regulation type in parameter 20 in
installer menu (see paragraph 8 “Installer parameters”).
Important points:
-
to be able to select “Amb”, “FLR” or “FLL” regulations in installer menu, external sensor
has to be connected to thermostat.
-
If there is an error with external sensor and if installer/user goes to parameter menu
n°20, “AIR” regulation will be selected automatically and external sensor error could
be deleted if thermostat is turned off.
Regulation
configuration Sensor LCD displaying Description
AIR Internal
Air regulation is done with internal
sensor.
Sensor measures temperature at the
thermostat position.
Amb External
Ambient regulation is done with external
sensor.
Sensor measures at a different position
than thermostat position.
FLR External
Floor regulation is done with external
sensor.
External sensor is connected to digital
thermostat and placed “in the floor”.
FLL Internal &
external
Floor limit regulation with external sensor
and internal sensors.
External sensor is connected to digital
thermostat and placed “in the floor”.
This measurement permits to check floor
temperature limits. Internal sensor is
used to do temperature regulation.
