INSTALLATION PARAMETERS MENU
Press the (OK) key during 5 seconds, then use (-◄)
or (►+) 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 (-◄) or (►+)
keys to adjust this value.
Press (-◄) or (►+) 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.

11
PARAMETERS
Default value & other possibilities
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
°CCelsius
°FFahrenheit
J5: Anti-lock-braking function of the pump when
the pump hasn’t worked on a particular day, start it
up for one minute each day:
Pmp Function activated
no Function deactivated
J6: Selection of the sensor used for the regulation:

12
Air:Room sensor only or room sensor with
floor limitation if the external sensor is
connected.
Flr: External sensor only without
limitations.
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 (-◄) or (►+) keys.
F0: Calibration of the external sensor.
The calibration must be done same as described
above if the external sensor is connected and

13
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:
5°CAdjustable From 5°C to „FH“
FH:Upper limitation of the floor temperature. Only
effective if the external sensor is connected and
selected:
28°CAdjustable From „Fl“ to 37°C
J7: Selection of regulation type:
rEg: Proportional band (PWM)
hys: Static differential of 0.3°K
CY: Proportional Integral regulation time cycle
value in minutes:

14
15 slow systems adapted to the regulation of
actuators.
on: Minimum starting time in minute
02 Adjustable 0 to CY /2
Of: Minimum off time between 2 regulation cycles
02 Adjustable 0 to CY /2
Bp: Value of the proportional band in °C:
2.0 °CAdjustable 1°C to + 7°C
* This value must be adjusted by a specialist.
Cp: Value of the compensation in °C:
0.0°CAdjustable 1°C to 8°C
* This value must be adjusted by a specialist.
Clr: All parameters are reloaded with default
setting values.
End: Press on the (OK) key to exit the parameter
menu.

„RF“ CONFIGURATION
The WFHTRF-HC was designed to manage the
Heat & Cool changeover of your installation.
First of all, turn off your thermostat.
The RF installation will be split in two parts.
1- Standard RF initialisation (Zone
control)
To learn (*) the RF thermostat with the receiver
you must put the receiver in “RF init” mode
(please refer to the receiver leaflet).
On the receiver, choose the zones which must be
managed by the WFHTRF-HC.

16
Once, on the thermostat you have just pressed
on the (OK) key during 5 sec, then the display
„RF“ must be appears.
The thermostat sends its configuration address by
radio signal.
oThe thermostat will send now the RF signal to
the receiver. Check on the receiver the good
configuration.
oIf the RF learning is not made correctly, check
the installation (antenna connection, supply
voltage...)
oIf the RF learning between the thermostat and
the receiver is good, put your thermostat in the
off mode
oOn the receiver you can exit the “RF init” mode
or configure another standard thermostat.
(Please refer to the receiver leaflet for this)

17
2- MASTER HC RF initialisation
To learn (*) the RF thermostat with the receiver
you must put the receiver in “MHC init” mode
(please refer to the receiver leaflet).
Once, on the thermostat you have just pressed
on the (OK) key during 5 sec, then the display
„RF“ must be appears.
oThe thermostat will send now the RF signal to
the receiver. Check on the receiver the good
configuration.
oOn the receiver you can exit the “MHC init”
mode.(Please refer to the receiver leaflet for
this)
Now you can check the RF distance, go to the
room which must be regulated. Put your
thermostat on the final position (On the wall),

18
then put the thermostat on the heating Hot mode
(setting temperature position 37°C). Close the
door and go to the receiver to check if the new
status of the thermostat has received.
oIf it’s good, adjust your setting temperature as
you want.
oIf it’s not good, check the installation (Antenna
position, distance...)
* To make the installation easier it will be better to
have the thermostat near to the receiver in learning
mode.
* Only one WFHTRF-HC thermostat must be
installed on the master WFHCRF-HC to manage
the heating & cooling change over.
