Hi Retired, trust you're enjoying retirement like me, but have to keep our hands in!!!! (I'm a retired Mech' engineer)
Many thanks for the advise, I assume changing the CH motorised valve is needed or can the micro switch be replaced in isolation?
Regards DRTGET
Hi,
I have a problem where the CH only works when the HW is on!!!!
I have changed the system programmer from a Danfloss CP715 (fitted in 1999) to a Danfloss FP715Si thinking the programmer was at fault - still have the problem.
The system is pumped with motorised valves on both CH & HW, both...
