معرفی

The Siemens RAA21 Room Thermostat has been designed to be used in heating only, or cooling only systems to maintain the designated room temperature. This reliable Room Thermostat is utilised in conjunction with zone valves and thermal valves, fans, pumps and oil and gas burners. This capable device features individual outputs for heating or cooling only, if the room temperature falls below the desired level the heating contact will close, and if the temperature exceeds the predetermined setpoint the cooling contact will close. The setpoints are selected via the front setting dial and the setting range can be mechanically limited by means of setpoint limiters fitted under the front cover. Typical applications for this Thermostat include temperature control use in residential buildings and larger industrial and commercial buildings. Safety standard II to EN60730-1 and the housing is protected to IP30.
