Temperature controller for single room applications with twoanalog output:
- The analog output ao1 can be used in VAV applications to control one or more VAV controllers
- The analog heating output a03 supplies a 3-point signal
Features:
- Energy Hold Off - In energy saving mode, the room temperature is reduced to building protection level, i.e. either the heating setpoint is significantly reduced or the cooling setpoint is significantly increased, for instance in a room with an open window.
- Stand By - The room temperature is reduced to stand-by level, i.e. either the heating setpoint is slightly reduced or the cooling setpoint is slightly increased, for instance in a room that is temporarily unoccupied.
- Frost - The frost protection function is activated if the actual room temperature falls below 10°C.
- Air Flush - The room can be ventilated with the
maximum volume flow, for instance
in order to purge conference rooms, hotel
rooms etc.
- External Temperature Sensor - An external temperature sensor can be connected to the analog input ai1, for instance in order to measure the average room temperature in the exhaust air duct.
- External Setpoint Shift - An external DC 0...10 V signal at the analog input ai2 can be used to shift the basic setpoint 0...10 K, for instance for the summer/winter compensation.
