The room temperature controller should be fitted in the main living room.
•
The place of installation should be chosen so that the sensor can capture the room
temperature as accurately as possible, without being affected by direct solar radia-
tion or other heating or cooling sources.
•
Mounting height is approx. 1.5 m above the floor.
•
The unit can be fitted to most commercially available recessed conduit boxes or di-
rectly on the wall.

When installing the room temperature controller, the base plate must first be fitted
and wired. Then, the unit is engaged at the top, swung downward and secured with a
screw.
•
For more detailed information, please refer to the installation instructions supplied
with the controller.
•
For the electrical installation, the local safety regulations and standards must be
complied with.

The control characteristics can be changed with the help of the DIP switches located
at the rear of the unit. For detailed information, please refer to the commissioning in-
structions.
•
If the reference room is equipped with thermostatic radiator valves, they must be set
to their fully open position.
