Question about wiring a CT87B Honeywell thermostat
I knew our furnace was not cycling properly, so I decided to move our thermostat to a different wall while also replacing the old T87F Honeywell...and then I discovered what I think is a wiring problem that essentially bypasses the anticipator that had not been set correctly anyway.
note: The old T87F is presently mounted on a newer base plate nearly identical to the plate for my new CT87B.
For a 4-wire heating/cooling system like we have, the instructions say to power Rh and Rc...but my picture shows how the current plate is wired differently. So before I follow the directions, does anybody know a reason I should not?
