I had this unit fitted last April.
However twice in the last few weeks I noticed the heating wasn't on. When I checked the relay box the red led was lit indicating a communication loss.
The Room thermostat has not been moved and batteries are fine. Communication test indicates the signal is being received in the position thermostat is located.
Any suggestions as to what might be wrong?
