I have 2 zone oil heat in my new/old home (1952). I added the 2nd zone in threw a professional plumber. My question is it seems like it's only working 1 zone at a time? I've been waking up to 58 degrees on zone 1, can you help? Zone 2 is upstairs.

((I added the 2nd zone in threw a professional plumber)). If the plumber did the work lately I believe he should look at it first. He may have made a mistake in wiring.

You were right it was a wiring issue my uncle is a lic. Elec. And he looked at it it's all set now thanks.

He was right, wiring issue.
