Ventilation
When the ventilation function is selected (RAB10.1), the heating and cooling contacts are always open and the
fan operates at the selected speed.
Changeover
Heating or cooling is selected with a switch located on the front of the thermostat.
Adjustments
The required temperature can be selected by a set point adjuster on the front of the thermostat.
The setpoint setting range can be mechanically limited by means of tappets under the unit over.
Mounting, installation and commissioning
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 authorized personnel may open the unit to perform service (Caution:250V!).
The unit must be isolated from the main 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 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.
Maintenance
The room thermostat is maintenance-free.
