3 Room Temperature Controllers with LCD 031 RDD10... for heating systems 2-position control with ON / OFF output for heating Operating modes: normal operation and energy saving mode Automatic operating mode change over as an option Mains-powered AC 230 V (RDD10) or battery-powered DC 3 V (RDD10.1) Use The RDD10... is used for the control of the room temperature in heating systems.
Functions 3031D01 The controller acquires the room temperature with its integrated sensor and maintains the setpoint by delivering control commands. The switching differential is 1 K. Q14 ON OFF W T[°C] T Room temperature SD Switching differential W Room temperature setpoint Q14 Output signal for heating SD Operating modes The RDD10... provides normal operation and, optionally, energy saving mode or OFF.

If there are thermostatic radiator valves in the reference room, they must be set to their fully open position. Maintenance The controller is maintenance-free. Sensor calibration If the temperature on the display does not agree with the room temperature effectively measured, the temperature sensor can be recalibrated. For that purpose, both buttons + and must be pressed simultaneously for 3 seconds.
