2 zone valves one thermostat........Can this be done.
I am doing a rewire of a squirrels nest of wiring. I am not sure how many hands have been into it. I have some Honeywell zone valves the ones with the 5 screws...2 for end switch and the rest for transformer and Tstats. And one Taco with the 3 screws. Someone prior to us had 2 zone valves on the first floor zone and apparently was trying to run 2 zone valves on the one tstat. The homeowner took the wires off the Honeywell I guess because it was just giving heat when non was wanted.......that is the best he can remember. I want to put the 2 on the one tstat. One is the Honeywell and the other is the Taco. ....Any Ideas???
