Evening,
So, ive had the evohome system for over 2 years trouble free. Yesterday an issue occurred:
- 1 Room didnt fire to the schedule, lets refer to that as living room, all other rooms fine (i have 7 TRVs in total)
- Now with that room i cannot get the TRV to work in conjunction with the call for heat. If i do an override on the evohome controller it changes on the screen and on the TRV screen to the requested temp, calls for heat say at 100% on the boiler and shows the same on the TRV (in the controller menu)
I had a spare TRV so i swapped it out, unbound and re bound the new one successfully - RF comms are strong with both the TRV and the BDR91. Same issue. All displays show its working but no heat.
If i hold the radiator pipe, its hot but no heat in the radiator. If i then remove the TRV and twist the black dial manually fully open, the radiator heats up :/ - ive requested upto 35 degrees so should definitely fire over room temp
The valve isnt stuck, the TRV is fine as i have also tested on another radiator which is actually working.
An issue just started this evening is that any override on the controller is showing a call for heat, changing the TRV but no heat is generated at all so the boiler isnt firing. Just happened the once - seems to be taking an age to influence the boiler (again RF comms is strong)
Its a pain this one, anyone any ideas - im thinking next steps may be to factory reset and rebind from the beginning
Probably makes little sense as its confusing me so no doubt the above will confuse everyone else :?
Any help is appreciated
Thanks in advance
