Key features of the RAB31.. fan coil room thermostat:
• Two-position control
• Gas-filled diaphragm
Adjustments
The required temperature can be selected by a setpoint adjuster on the front of
thermostat.
The setpoint setting range can be mechanically limited by means of setpoint limiter
under the cover.
Notes
The thermostat should be located where the air temperature can be sensed 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 most commercially available recessed conduit boxes or directly
on the wall.
Only authorised personnel may open the unit to perform service.
The unit must be isolated from the mains supply before opening.
When installing the unit, fix the base plate first then hook on the thermostat body and
make the electrical connections. Then fit the cover and secure it (also refer to seperate
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.
