EDIT: Subject should clearly have been 'Heating not coming ON when it should'
Hi
I've got a Honeywell Evohome system which I've had for about 6 months, on the whole it's been working brilliantly. However, with this snap of cold weather we've had I've noticed the heating in one of the rooms isn't coming on when it should be. The rest of the zones appear fine.
Here's my setup:
- Evohome controller (being used as a thermostat for the zone it's in)
- BDR91 relay
- Infrared (electric) heating panel
- T87 thermostat
So what's happening is the temp is set to 21c at the thermostat, and if I look at the System Summary on the Evohome I can see that the zone in particular is requesting heat (it's set to 100%). The thermostat knows the desired temp is 21c, and the current temp is 18.5c (for example). But the BDR91 relay isn't as on as frequently as it should be. It's not that the heating never works, it's just not heating up enough.
I've done an RF comm check and the comms to that zone checkout ok.
At the moment I've not reset anything, as I said, it works OK for the other zones and this zone does work, it's just not as warm as it should be.
Any advice / extra info I can provide?
Thanks, Matt
