Hi
A Honeywell V4043H1056 2-port motorised valve in our CH system has
stuck. I suspect that the synchronous motor has failed.
A replacement Honeywell motor seems to cost around £25. Screwfix do a
Drayton motor for around £13 (page 420 of Spring 2010 catalogue),
which is supposed to fit many valves.
Please can anyone advise whether the Drayton motor is suitable for
this Honeywell valve?
I did see a post on another forum ('diybanter') that stated:
"Change the motor (for Honeywell, they recommend you get a Honeywell
motor as it they are more robust as their valves can remain open (i.e.
powered) to CH if that was the last demand, even if demand has now
ceased, therefore more wear on the motor)."
Is this really true? I would have thought that a microswitch would
stop the motor when it has reached position.
Best regards
David
