1 3 003 Room hermostat RAA30 Adjustable room thermostat for heating only or cooling only systems Room thermostat with manual O/OFF switch wo-position control witching voltage AC V Use he RAA30 room thermostat is used in heating only or cooling only systems to maintain the selected room temperature ypical use: Residential buildings ight industrial buildings In conjunction with zone valves, thermal valves gas or oil burners fans pumps Functions OFF O he front of the unit carries an O/OFF switch In the OFF 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 CE13003E iemens Building echnologies HVAC Products

3 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 15 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 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 RAA3016/GR / 3026/GR Power consumption of each ED Current Frequency witching differential D etpoint setting range 8 30 C Operation Climatic conditions emperature Humidity Pollution degree ransport / storage Climatic conditions emperature Humidity Mechanical conditions Packaging AC V AC 230 V +10/-15 % 05 VA (Only RAA3016/3026) 02 6 (2) A 50 or 60 Hz 1K to IEC class 3K C <95 % rh ormal, to E to IEC class 2K3/1K C <95 % rh class 2M2 single packaging / min order 20 pieces iemens Building echnologies Room hermostat RAA30 CE13003E HVAC Products /6
