Notes
The room temperature controller should be mounted in a location where the air tem-
perature can be measured as accurately as possible without getting adversely affected
by direct solar radiation or other heat or refrigeration sources.
Mounting height is about 1.5 m above the floor.
The unit can be fitted to a recessed conduit box.
• Only authorized staff may open the controller.
Caution: AC 230 V!
• The cables used must satisfy the insulation requirements with regard to mains
potential
When mounting the unit, fix the baseplate first. Then, make the electrical connections
and fit and secure the cover (also refer to separate Mounting Instructions).
The controller must be mounted on a flat wall and in compliance with local regulations.
If there are thermostatic radiator valves in the reference room, they must be set to their
fully open position.
The controller is maintenance-free.
If the temperature on the display does not agree with the room temperature effectively
measured, the temperature sensor can be recalibrated. For that purpose, both buttons
