2 First Installation
This section will guide you to set up your thermostat for the first time.
2.1 Batteries installation
- Open the two side’s covers and insert the 2 AAA Alkaline supplied batteries (or remove
the small protection sticker if the batteries are already installed in the compartment)
- Close the two side’s covers.
2.2 RF installation
Please have a look at the list of all receivers compatible with this thermostat in Technical
Caracteristics section.
2.2.1 With receivers
- First of all to configure your thermostat with the receiver, you must put your receiver in
RF init mode. (refer to the receiver leaflet, only the RF receivers of the same range are
compatibles)
- Press and maintain the edition key ( ) during 5s, then the parameter « INI » must be
displayed.
The thermostat will send now the radio configuration signal to the receiver.
- After few seconds, the thermostat and the receiver should exit by their self the RF init
mode, this is the normal procedure to confirm a correct pairing.
- You can check the RF distance. Go to the room which must be regulated. Put your
thermostat on the final position (On the wall or table...), then put the thermostat in
Comfort mode (setting temperature position 37°C). Close the door and go to the receiver
to check if the new thermostat status has received.
- Return to the thermostat and switch it off. Check on the receiver again if it’s also
switched off.
If the RF signals were received correctly, adjust your setting temperature as you want.
If the RF signals weren’t received correctly, check the installation (Receiver position,
distance...) or restart the RF init rules to be sure.
Remark: To make the installation easier, it will be better to have the thermostat near to
the receiver during the configuration mode (a minimal distance of 1 meter must be
respected).
2.2.2 Case of central (BT-CT02)
The link is done with central (BT-CT02).

simultaneously on the edition key ( ).
- The “ ” logo will be displayed on the screen.
Repeat the same procedure to unlock the key board.
4.2 Open window function
This function is able to stop heating if thermostat detects an unusual decrease of
temperature (open window).
Principle:
If the displayed temperature (internal or ambient sensor) decreases by 3°C or more
during a 5 minutes period (or less), the thermostat stops heating for 15 minutes. If the
temperature continues decreasing, it continues to stop.
During this stop, the room temperature will blink.
Return to normal mode:
The thermostat returns automatically to normal mode after the stop period.
The function can be overridden by pressing the (OK) button during the stop heating
phase.
The blinking temperature should stop to indicate the end of the detection.
Special cases:
- This function doesn't work if Thermostat is in Floor regulation
- This function doesn't work if Thermostat is in OFF / Antifreeze Mode
- If temperature is less than 10°C, thermostat will regulates at 10°C during the stop
phase (refer to chapter 5, parameter 06)
- This function doesn’t work in cooling configuration
4.3 Humidity measurement (*)
Thermostats measure the humidity in the air. This measure allows:
- To regulate the humidity in the air (refer to parameter 34 chapter 8)
- To protect your system against condensation (refer to parameter 35 chapter 8).
4.4 Visualization
With this function, you can quickly view the current temperatures of the different sensors
connected to your thermostat (floor, remote, external). On the main screen, press
several times on the escape key ( ). This “scroll function” is only available on the main
screen:
You will see in the order of each press:
1/ the setting temperature followed by the thermostat
2/ the ambient temperature
3/ if the external sensor is connected: the outside temperature
4/ the humidity percentage (*)
Remarks :
- refer to chapter 1.2 for icon meanings
- if Parameter “Sen” is set on “Air” (refer to chapter 8), the remote sensor will be used as
an external sensor.
