I have single heat pump with a zonal control diverter box with two of these thermostats controlling heat and cool in a single story home. They were working fine with my Vera Plus but when I excluded them from the Vera I had to do a factory reset to work with HA. When I reset them I set them to Heat Pump Mode but they wouldn’t cool the house when installed earlier this year in the summer so I reset them again and set them to work as a conventional gas FAU. This worked all summer just fine. Now that it is cooling down I set them to heat. The fan came on but not the Heat Pump so all it did was blow cool air in the ducts around the house. I tried setting them to Heat Pump control to no avail. Any suggestions on how to fix this?
