The recommended mounting height for the indoor climate sensor is between 1.2 m (4 ft) - 1.5 m (5 ft) when mounted on the wall. The positioning of the sensor should be adapted to the application. (e.g. according to what area of a space is generally occupied)

Install the mounting frame at the desired location and connect the power supply (orange/white terminal). When using batteries, remove the orange/white terminal and insert the supplied AAA batteries.

The sensor is then snapped into the mounting frame. For free-standing use, install the supplied back cover instead of the mounting frame.


In delivery state, pairing mode will be active after the power supply has been established. This is indicated by the status LED flashing red/green/orange.

Then follow the pairing procedure

To activate the pairing mode manually, hold down the pairing button for at least 5 seconds after establishing power supply.
