Bgriff Posted April 8, 2017 Share Posted April 8, 2017 i'm having an issue with my thermostats. They are both wired the same. The upstairs thermostat works without battery. The thermostat wired the same way will not work without a battery? Any suggestions as to what is going on? Link to comment Share on other sites More sharing options...

Sounds like the one that needs a battery is not getting the proper 24VAC from the unit. Likely that the common wire is connected at the thermostat but not actually connected to the proper terminal at the unit. Link to comment Share on other sites More sharing options...

I've run into that before where the HVAC guys will terminate on the t-stat side but not on the unit. Link to comment Share on other sites More sharing options...

He had to put them both in the same port. Link to comment Share on other sites More sharing options...
