It’s an old system but never had an issue before.
If I turn down the hall thermostat it still runs non stop.
Sliding the switches to off on the Honeywell programmer doesn’t make any difference.
Over the last 2 weeks I could hear a squeak from one of the valves when the heating turned off.
When I turn the hot water off I can hear its valve working.
But when I turn off the heating on the programmer no sound from the heating valve! The pump keeps running, the boiler keep running.
Only way to turn off boiler and pump is by turning off power to the control programmer, then everything stops, but I don’t hear any noise from the valve as I normally would when everything stops.
The hot water valve has some resistance when pushed all the way to the left, but the central heating valve has no resistance at all and moves freely all the way to left and right!
The valves are Honeywell V4043H1056 2-Way Zone
Programmer is Honeywell ST699
Is this maybe just the header or motor problem and I can simply just change that?
Or is it the valve has seized and maybe blown the motor/header etc and I need to swap out for a complete valve and header unit?
Not familiar with heating systems but willing to have a bash at it (without a hammer)!
