My Evohome install has been fine since I installed it in mid Feb however over the past week or so the BDR91 has been showing a solid red led and this can only be cleared by removing the front panel and resetting it.

There is no fault logged in the fault log any time this occurs (I am leaving it for a few hours tonight to make sure) and a comms check fails even if the controller is within a few inches.

When the BDR91 is working normally it is fine, no faults logged at all. This appears to be the opposite to what a lot of others have seen (comms check good but failing to trigger). The mounting doesn't quite make the 30cm rule but is close.

Is this a comms fault or do I have a faulty unit?
