Hi,
I had a 3-way valve V4073A fitted a year or two ago. When there is no power or the hot water is on the lever is in the B position for diverting water into my hot water cylinder.
However if I turn the cylinder thermostat down, and the central heating control up the lever stays in the same place. Should I be able to see the lever move over to central heating position, if it is working properly? I have a 5 wires for the valve, with grey and white wired together.
When I move the lever over there manually with CH on there is no resistance and it stays. When I turn off the CH and just have HW on the lever springs back. This looks as though there is an energizing voltage getting through, but it doesn't move the lever across by itself.
My water seems a bit hot - it was over 62 Celcius, when the tank thermostat is set to 55. I don't generally run HW with no central heating, because I just use the immerser.
Thanks,
Phil
