KNX eTR 101, signal white RAL 9003

Room Temperature Controller


The Room Temperature Controller KNX eTR 101 measures the room temperature and displays the current value. Via the bus the device can receive an external measured value and process it with own data to overall temperature value (mixed value).
The KNX eTR 101 has got an integrated PI controller for a heating and a cooling system (one or two step). The room temperature is adjusted by means of the + and - touch buttons.
