Have HVAC Questions? Ask an HVAC Expert for Answers
Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. First I’ll need some more info so I have a more complete picture of you situation.
Do you have zone valves?
If you have 3 zones you either have zone valves or a circulator/pump for each zone. I need to know which type of system you have. You can't get a reliable 24 v common from the aquastat relay
Can you give me a picture? you can post pics here by clicking on ADD FILES next to the SEND button.
If you can't post a pic I need the brand of the zone valves and you need to locate the transformer that powers them.
That's OK, I'm usually online between 8 am & 7 pm EDT (more or less, I do take breaks). I'll respond as soon as I can.
