Hi all, I have a zone valve problem. I have two zone valves on a hot water baseboard heating system. The basement zone valve allways seem to be in 'open' position. Can anyone tell me what the problem might be? I think it is wired wrong. Can anyone tell me how the wires on a zone valve should be wired?
Thanks, Dave.
Most zone vlaves have the wiring diagram printed right on the power head. Check it and see.....
Describe the valves wires or terminals
Sounds like your zone valve is stuck open. You can try hitting it to loosen. If that works it probably will not work for long. Sounds like you need a new zone valve. How old is the one you have, if it is anywhere close to 10 years most likely needs replacing.
check its automatic/manual lever.
