•
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.
•
If the reference room is equipped with thermostatic radiator valves, they must be set
to their fully open position.
•
If the measured room temperature does not agree with the set room temperature on
the setting knob, the detector should be recalibrated (please refer to "Calibration of
detector").
