Thus far I have:
- replaced with new batteries.
- turned down temp and switched the breakers
- turned heat back up, no response
Can a pilot be out for one zone? The other two are warm and cozy. Did the pipes freeze? Or they use same pipes. I answered my own question! I lowered heat in zone 2 and 3 so more would go to zone 1.
Yesterday the power did go out in part of the kitchen. Did that affect zone 1 because the temperature was left at 65 the night before.
