tions
•This product should be installed preferably
by a qualified professional. Subject to obser-
vation of the above terms, the manufacturer
shall assume the liability for the equip-
ment as provided by legal stipulations.
•All instructions in this Installation & Operation
manual should be observed when working
with the thermostat. Failures due to improp-
er installation, improper use or poor main-
tenance are voiding manufacturer liability.
• Any
attempt to repair voids the responsibili-
ty and the obligation to guarantee and
replacement from the manufacturer.
•Do not cover the thermostat for accurate mea-
surement of ambient temperature. Therefore
the sensor must never be hidden behind
thick curtains, furniture, etc… Alternatively,
a remote sensor should be used.

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 tem-
perature 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 select-
ed 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 thermo-
stat 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

9
Deutsch | Français | Nederlands |English
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 heat-
ing 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).

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.
