The individual room control en:key consists of two communicating system components, the en:key room sensor and the en:key valve controller. Both work by radio in the network.
The room sensor detects whether a room is being used - and then automatically controls the comfort or the saving temperature. In addition, he "learns" how the user behavior is over days and weeks - and agrees to the "heating curve" in the room; This saves more energy.
No battery or wiring is required to operate the equipment.
