1. Connect the room thermostat insert according to the wiring diagram.
2. Mount the insert in a wall box. In doing so, the connection terminals must be facing down.
Sufficient connection space remains thanks to its installation depth of only 24 mm.
3. Attach the frame and attachment to the insert.
4. Switch on the mains power.
5. The load can be switched using the TEST push-button.
− The attachment LED lights when the load is switched on.
− Cooling is active if 230 V is applied to input C.
Note: The insert only functions with room thermostat attachments. All other attachments have
no function.
6.3 Functional description
With the Standard display for room temperature control, you control the room temperature
manually and time-controlled according to your wishes. The other functions such as tempera-
ture drop detection or heating optimisation are described below.
6.3.1 Heating or cooling operating mode
Modern heat pump heating systems often also enable rooms to be cooled. The room thermo-
stat attachment supports this function with the “heating or cooling” operating mode.
In this operating mode, continuous regulation to the specified cooling temperature takes place.
There are no time programs in cooling mode. Any change of the cooling temperature can only
be made via the temperature parameters and not via the Plus and Minus buttons.
In combination with a room thermostat insert, cooling mode is activated by applying mains
vol-tage to input terminal
C . For switch inserts, cooling mode is activated by applying mains
voltage to the satellite unit input “1”. The heat pump usually has a corresponding output or an
installation switch can be used.
6.3.2 Frost protection and temperature drop detection
The frost protection temperature is the minimum temperature that is regulated to prevent frost
damage. In the event of a sharp drop in temperature, e.g. after a window is opened, the insert
regulates the temperature to the frost protection temperature for a maximum of 30 minutes.
The temperature drop detection parameter must be activated for this.
