Ok, yes good idea - had it for 3 years so might just have gone bad? Anybody else find their contacts have failed???

Briefly turns blue f lol ash for a while, when this happens I can set the system ok. I then walk to the house try to unset and re-set and the error message comes back 'not polling door 8 - all the other door and window contacts are ok and ready to be set, but the system sends the message "cannot...

All the other 22 door and window contacts working ok. Any ideas?

Battery replaced and installed correctly. ????

My Pyronix home enforcer won't set. I recently have an issue getting the system to set, it gives an error message - 1) door 8 - wirles supervn Fl 2) door8 - wirles Poll Fail I've changed the battery in the door contact, I then go to the panel and reset engineer code and it resets at the...

Many thanks I'll give the items a check as suggested.

I'll also check the seemingly offending grey wire for integrity, too, thanks.

Maybe the Drayton motor supply is not quite up to the job, and a Honeywell valve be used. I swapped to Drayton because of the easily replaced actuator head, but see Honeywell now have caught up and market a similar replaceable head only, unit?

However, I will alter the hot water cycle to coincide with the heating-off cycle as suggested as a temporary repair method, untill this issue can be resolved, maybe.

Thanks for the reply and suggestion. Unfortunately, I'm an engineer who insists on knowing how everything works and needs to have systems working correctly! (It's an engineer thing!) - there's no reason why the valve should "stick" - it's all new, and replaced each time. So I need to establish...

Every one of the actuators has behaved in the same way - give the actuator head a clout and the system works again. Funnily enough, the system always comes back on in the morning!

Should I check the supply from the room stat? What sort of issue would a broken room stat display? How to check???

Which wire is responsible for driving the switches to the heating position? (The grey?) Does that get it's supply via the room stat? Do you think the room stat is not sending enough current to move the motor towards the Heating position?

A broken programmer? ( Presumably not that)? as once the 3way activator is clouted it all fires back up!?????

What would cause the microswitches to be stuck ?

Thanks for the reply. I now know how it's supposed to work, but would love to talk to John Ward to discuss why the system is stalling, and a clout with my hand suddenly gets the supply back to the Heating service, after the hot water is switched off by the Potterton Programmer??

I'm on my 4th Drayton mid position MA1 valve in two years and wonder if my problems have been discussed before, with any results or suggestions greatly appreciated..... The pottery on programmer will allow the valve to operate in the normal way, i.e. hot water only, heating only, or mid...

Andrew, Thanks for the reply. Pics of Potterton attached. White taped wires added recently for Burner L, and Frost stat when I moved bOiler outside. Potterton connections at connectors 4&5 are the ones I would like to investigate, as Altech controller only has 4 connectors ( not 5?)...
