Siemens Room Thermostat RAB10... CE1N3011en
Building Technologies 25.02.2008
Technical design
Key features of the RAB10... fan coil room thermostat:
• 2-position control
• Gas-filled diaphragm
Adjustments
The required temperature setpoint is selected with the setting knob on the front of the
thermostat.
The setpoint setting range can be mechanically limited by means of a setpoint limiter
under the unit cover.
Note
The thermostat should be located where the room temperature can be acquired 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 thermostat can be fitted to most commercially available recessed conduit boxes or
directly on the wall.
Only authorized personnel may open the unit to perform service (Caution: 250 V!).
The unit must be isolated from the mains supply before opening.
When installing the unit, fix the baseplate first, then hook on the thermostat body and
make the electrical connections. Then, fit the cover and secure it (also refer to separate
mounting instructions).
The thermostat must be mounted on a flat wall.
The local electrical regulations must be complied with.
If there are thermostatic radiator valves in the reference room, set them to their fully
open position.
The room thermostat is maintenance-free.
The diaphragm is filled with environmentally friendly gas.
The housing is made of plastic.
