Installation and settings

The room thermostat insert has six terminals N, L, heating (output), C (cooling input), 2x external temperature sensor connection for external temperature measurement.

The line conductor is connected to L and the neutral conductor to N. The connection for cooling is made on C and for heating on heating. The external temperature sensor for external temperature measurement is connected to the two external temperature sensor connections.

Note the following for the installation:

Proceed as follows for mounting:

  1. Connect the room thermostat insert according to the wiring diagram.
  2. Mount the room thermostat 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 cover to the room thermostat insert.
  4. Switch on the mains voltage.
  5. With the TEST button, you can switch the load.
    - The LED for the cover is illuminated when the load is switched on.
    - If there is 230 V at input C, cooling is active.

Note

The room thermostat insert only functions with room thermostat covers. All other attachments have no function.
