We have hot water baseboard, 1 circulator, 2 zone valves, 2 thermostats (1st flr, 2nd flr), Honeywell. Last week 1st flr heat stopped working. Forecasted to be cold in a couple of days, need to fix this. I think it's the powerhead on the 1st floor zone valve but need to make sure before I buy one.
With the furnace warm, if I manually open the 1st flr zone valve we get heat to the 1st flr.
If the furnace is cold and the 2nd flr stat is NOT calling for heat, if I turn the 1st flr stat all the way up the furnace DOES NOT come on. I thought this might point to a bad stat but if I cross the 1st flr stat wires the furnace still does not come on.
Thanks for any Help
