Hey, I've got a zoned system that serves the kitchen and upstairs and is controlled by 3 thermostats.

Recently I swapped the old stats out with Amazon WiFi thermostats and yesterday despite the temp setting it was 91* upstairs.

Thinking I did something wrong with the wiring bc the old stats had jumpers between a couple of the terminals but I just plugged the wires into the corresponding terminals on the new ones with no jumpers. With a set up like this, where would I need a jumper to make the system work properly?

Never mind, had a buddy who runs an HVAC company come by and he determined it was a bad capacitor that was causing the condenser fan to run backwards.
