Hi
I have just recently installed a new pump, boiler controller, room stat & cylinder stat in my system and now having problems when there is a demand for HW. When boiler programmer demands HW, the mid position valve moves in to CH mode, when demand is cut the valve returns to normal position. The cylinder stat when adjusted up or down ignites/cuts boiler respectively .The CH works fine, and I have rewired the old programmer and is still CH on HW demand. The valve motor is working, is the rest of the valve on its way out? Or have I messed up the wiring somewhere. Any advice would be most helpful. Cheers
Honeywell ST6450 replaced with Drayton LP722 boiler programmer (wired as per instructions and set to P for a pumped system)
Honeywell L641A replaced with Drayton HTS3 cylinder stat
Honeywell T6360 replaced with Drayton RTS1 room stat
Mid position valve Myson MPE 322
Glowworm Economy Plus 30F boiler
