Siemens Room temperature controllers CE1N3036en
Building Technologies 13.10.2008
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 authorised staff may open the controller.
Caution: The switching output voltage is from AC24V up to AC250V
• 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
+
and must be pressed simultaneously for 3 seconds. Then, the temperature
displayed can be changed by a maximum of +/- 10 K by pressing the
+
and
-
but-
tons. Five seconds after the last push of a button, the controller will automatically return
to the normal operational status.
The setpoint limitation is used in some specific applications where the setpoint tem-
perature is required to be above 35°C (Less than 60°C). For that purpose both buttons
+
and
-
must be pressed simultaneously for 5 seconds. The top row of the LCD will
then display 35°C to signify the default setpoint limitation whereas the bottom row will
display SPLt to signify the setpoint limitation mode. The temperature limitation can be
changed by pressing the
+
and
-
buttons. Five seconds after the last push of a but-
ton, the controller will automatically saved the value and return to the normal opera-
tional status.
If the battery symbol appears, the battery power is almost exhausted and the batteries
should be replaced. Only AAA alkaline batteries have to be used.
To reset, first press and hold the button
, then press the two buttons
+
-
simultane-
ously for 3 seconds. All individual settings will be reset to their standard values.
