Has anyone every hooked up a nest with a zone valve?
I hooked up a Nest 3rd Gen today with a standard Honeywell V8043E1012 24VAC Zone valve and for some reason it would not kick on the zone valve. If I touch the Rh and W1 wires together the zone valve opens and heat turns on.
If I move the Rh and W1 wires over to Rc and Y1 and call for cooling the zone valve opens and the heat turns on.
I am not sure if I did anything wrong but I attached a diagram of basically how it is hooked up.
Maybe one of you encountered this issue before.[Link: drive.google.com]
