Hi all - I have a UFH system in a fairly new house, problem is downstairs (zone 1 is fine) upstairs (zone 2) is cold - not getting up to temp, had a nose at the controls, pump etc and all seems to be ok except the honeywell motorised valve (HMV), when I move the pin to Manual the upstairs warms up in no time...two questions...
Is it just the HMV at fault?
Will it cause any damage by moving the MV to manual?
Hope you can help?:28:
