Important:
The thermostat must be disconnected from its
power supply before its housing is opened.

Loosen the screw on the underside.
Open the housing by removing and then lifting
off the housing lid on the underside.
Now fix the base plate with the screws supplied
on the wall or on the flush mounting box.
