IV. WIRELESS CONTROLLER RECEIVER
The EU-297v2 regulator communicates with the heating device (or the CH boiler controller) by means of a radio signal
sent to the receiver. Such a receiver is connected to the heating device (or the CH boiler controller) by means of a two-
core cable, and communicates with the room regulator using a radio signal.
The receiver has three control lights:
• red control light 1 – signalises data reception;
• red control light 2 – indicates receiver operation;
• red control light 3 – goes on when the room temperature fails to reach the pre-set value – the heating device is switched
on.
NOTE

In case of no communication (e.g. due to discharged battery), the receiver automatically disables the
heating device after 15 minutes.
V. FIRST START-UP
