  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").
