Hi,
I have a fault with my CH that has only started in the last few days and its driving me mad.
My system is set up as follows - CH, HW and UFH.
There are two port valves on each and they all work independently.
CH stat is Salus RF, UFH is Polypipe again RF.
Programmer for CH & HW is Honeywell 7 day.
The system has worked perfectly for 12 months (when it was all installed)
In the last few days the CH has stopped coming on but intermittently. HW and UFH still work fine.
The Salus receiver is picking up the stat signal just fine (light goes green) but the 2 port valve isnt powering up and obviously not calling for heat from the boiler. Sounds like a faulty 2 port you're thinking? Well thats what I thought, but the problem is after hours, sometimes a day the valve will open and the CH works!
There seems to be no pattern to this, it just opens when it feels like it.
For example, not CH all night last night or this morning when it would usually be on, then at 0915 this morning (3 hours after it is meant to come on) the valve decides to power up even though the Salus receiver has had a green light all morning.
We have the CH on constantly on the programmer and the clock in the Salus room stat controls when the heating comes on etc.
I would have thought a 2 port either works or it doesnt. Has anyone come across a fault where the 2 port sometimes works and sometimes doesn't?
I dont want to go replacing the head for no good reason.
Any ideas would be appreciated!
Thanks
