MODE DESCRIPTION
Use the (OK) key to change the mode in the
Operating mode menu. (The active mode is framed)
OFF mode:
Use this mode if the zone managed by the
thermostat needs to be turned OFF.
The display will be turned off and all parameters are
saved. (Careful in this mode your installation can
freeze).
COMFORT operating mode:
The comfort temperature will be followed all the
time. By pressing keys (-Ż)or (Ź+) the comfort
temperature starts to blink and can be adjusted.
The measured temperature
reappears after a few
seconds.

7
REDUCED operating mode:
The comfort temperature will be followed all the
time. By pressing (-Ż)or (Ź+) keys the comfort
temperature starts to blink and can be adjusted.
The measured temperature (OK) reappears after a
few seconds.

INSTALLATION PARAMETERS MENU
Press the (OK) key during 5 seconds, then use (-Ż)
or (Ź+) to select the installation parameter to be
adjusted.
Press (OK) to toggle the parameter setting or edit
the value.
If the value starts to blink you can use (-Ż)or (Ź+)
keys to adjust this value.
Press (-Ż)or (Ź+) keys at the same to reset this
value to the factory default value. Once you have
adjusted the value press (OK) to validate this
parameter value.

rF: Radio configuration mode (see the
corresponding section).
Press (OK) on this parameter to exit the
parameters menu end come back to the main
display.
JO: Type of degrees displayed

J1: Operating mode:
Hot for heating application
CLd for cooling application
CY: Proportional Integral regulation time cycle
value in minutes:
15 slow systems adapted to the regulation of
actuators.

Bp: Value of the proportional band in °C:
2.0 °CAdjustable 1°C to + 7°C
Increase the value if the temperature in the
room is unstable.
J5: Anti-lock-braking function of the pump when
WKHSXPSKDVQ¶WZRUNHG on a particular day, start it
up for one minute each day:
Pmp Function activated

J6: Selection of the sensor used for the regulation:
Air:Room sensor only or room sensor with
floor limitation if the external sensor is
connected.
Flr: External sensor only without
limitations.

12
J7: Selection of regulation type:
rEg:Proportional band (PWM)
hys: Static differential of 0.3°K
Cp: Value of the compensation in °C:
2.0°CAdjustable 1°C to 8°C
* This value must be adjusted by a specialist.
A0: Calibration of the internal sensor
(The calibration must be done after 12Hours
working with the same setting temperature)
- To check the temperature in the room, put a
thermometer at 1.5M distance to the floor in the
concerned room and wait 1 hour to be sure that
the thermometer show the correct temperature.
Then you can enter the value saw on the
thermometer with (-Ż)or (Ź+) keys.

13
F0: Calibration of the external sensor.
The calibration must be done same as described
above if the external sensor is connected and
used like an external ambiance sensor.
If the external sensor is used as floor sensor, the
thermometer should be put on the floor.
FL: Lower limitation of the floor temperature. Only
effective if the external sensor is connected and
selected:
