i tried wiring both upstairs and downstairs zones. Downstairs worked
fine. Upstairs I followed the wiring from the attached photo, but hot
air is blowing from vents when it should be cooling. does anyone have
any wiring tips?
Thanks, Patrick. The white wire is connected to Y2 in the original
thermostat. i’m attaching the photo again. where do I locate the zone
controller? if my wiring is correct, why is heat coming out of vents on
cool setting? I don’t have a heat pump to...
