Hi All,
I've just moved house, and used it as an excuse to upgrade our old B&W evotouch to the latest wifi version, along with 8 new HR92 valves (purchased from the evohome shop). 4 HR80s are carried over from the previous installation.
The problem I'm having is that the boiler cycles every 10 mins, whether there is heat demand or not. It appears to be the failsafe kicking in, however failsafe is disabled in the evohome head unit.
I've tried to be methodical with trying to figure out what's going on:
I've tried multiple factory resets + batteries out of the controller.
Reset all of the HR units. When active the HR units respond to changes of temp from the controller the HR92s report overrides back to the controller.
Reset the BDR91 multiple times.
Changed the BDR placement - moved the controller to be 3m line of sight from the BDR, moved the BDR91 so it's sat in 50cm of free air dangling by the cable, even tried the old BDR91.
Wondering if it was a rogue HR unit, I have pulled the batteries out of each one by one to see if one of them is triggering it, but even with all of the HR's with no batteries it still triggers once every 10 minutes.
If I unplug / take the batteries out of the controller (so there are no active evohome devices at all bar the BDR) it will still trigger once every 10 minutes.
Signal strength between the controller in it's normal location is reported as excellent, 5 flashes on the BDR.
No comms failure logs are created.
We are in a rural location so I don't think that neighbours etc could be interfering with comms.
If I do a full reset and set up a single zone (default of the living room) with a single HR92, it *seems* to behave itself. If I add more zones that's when the boiler cycling seems to start. I've gone though both the guided setup and manually adding zones and end up with the same result both times - boiler failsafe.
I've got it all unplugged with the batteries out for yet *another* full reset, but does anyone have any suggestions?
