Hi all, hoping someone can help me. My home is heated by FHW baseboard and gas. I have 4 zones. The one zone that is giving me issues is for my living room. It doesn't happen all the time.
I have the thermostat set to 72, heat comes on then the heat stays on and CRANKS. Seems the zone is staying open and keeps pushing hot water through the pipes until I physically have to take the wires off the zone valve to shut it off.
If I leave the wires off for a while it will return to normal most times. This has happened maybe 4 or 5 times last year. I'd like to try to figure it out before I have to turn the heat on this year.
A friend of mine mentioned that maybe it the transformer. He also mentioned changing out the transformers to something simpler but not sure what that would be.
Anyone ever experience anything like this? No I have not had a chance to put a meter on the valve when this happens as I don't own one.
Thanks.
