Temperature Controller for Single Room Applications (2 Analog Output)

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.
