EU-290 user’s manual

In the case of wireless connection, the diagrams presented above should be used – the two-core
communication cable should be connected to appropriate sockets in the receiver.
IV. Receiver for wireless controller
EU-290v2 regulator communicates with
the heating device (or the CH boiler
controller) via radio signal sent to the
receiver. The receiver is connected to the
heating device (or CH boiler controller) via
a two-core cable whereas the
communication with the room regulator is
performed wirelessly via radio signal.
The receiver has the following control
lights:
• green 1 – indicates data reception, goes
on during channel change;
• red – indicates receiver operation
• green 2 – goes on when the room temperature fails to reach the pre-set temperature – the
heating device is switched on.
How to change the communication channel
Channel “35” is the default communication channel in the room regulator. The channel may be
easily changed (if the current channel is used by other devices). To change the channel, press
and hold the channel change button for about 10 seconds until the green control light (1) goes
on. Next, change the communication channel in the room regulator following the procedure
described in part VIII.c.10. The green light on the receiver should go off.
