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
+
and
must be pressed simultaneously for 3 seconds. Then, the temperature
displayed can be changed by a maximum of +/- 3 Kelvin by pressing the
+
and
-
buttons. Five seconds after the last push of a button, the controller will automatically
return to the normal operational statuses.
If the battery symbol appears, the battery power is almost exhausted and the batteries
should be replaced.
