Hi guys,
Having a bit of a headache after attempting to rectify a 'simple' fault on my system.
After having trawled thru pages of posts relating to Drayton MA1 3-port valves, I haven't yet come across the same problem?
After coming home this week to no heating but hot water only, I obviously suspected the 'mid-valve' playing up.
- the actuator was 'clunking' and not moving over to 'H' position so I replaced the head unit like for like.
(Opted for this rather than syncron motor only. - poss false economy if a micro-switch was at fault?)
Now the valve seems to be operating correctly. i.e. the lever indicator is moving to the appropriate positions when heating/HW/both are selected at programmer but I cannot get heating ONLY. - Only with H/W!
I've checked the voltage at the valves orange wire and have NO supply which would obviously indicate a faulty micro-switch? - On a brand new unit??!! (bought yest from City Plumbing)
Is it poss I've been sold a duff unit, or could the fault be something else?
I've yet to disconnect and test the valve wiring independently as per 'doitmyself' posting back in 2009.
But just thought Id ask if anyone else may have had a similar problem?
Incidentally, my system comprises 'Lifestyle' programmer/Drayton room and cylinder stats/controlling brand new Grant, oil-fired boiler.
Hoping someone out there can point me in the right direction!!
