In the position, the input voltage is physically separated from the output voltage. he RAA30... room thermostat has separate ouputs for heating only and cooling only. If the room temperature falls below the selected setpoint, the heating contact will close. If the room temperature exceeds the selected setpoint, the cooling contact will close.

otes Mounting, installation and commissioning he room 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. he 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 (Caution: AC 24 250 V). he unit must be isolated from the mains supply before opening. Maintenance Mechanical design When installing the unit, fix the baseplate first then hook on the thermostat body and make the electrical connections. hen fit the cover and secure it (also refer to separate mounting instructions). he thermostat must be mounted on a flat wall. he local electrical regulations must be complied with. If there are thermostatic radiator valves in the reference room, set them to their fully open position. he room thermostat is maintenance-free. he diaphragm is filled with environmentally friendly gas. he thermostat housing is made of plastic. echnical Data Operational data Environmental conditions witching capacity Voltage RAA30...
