Siemens Building Technologies Room temperature controllers CE1N3031en
HVAC Products 24.09.2003
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.
