Question about Honeywell CT3600 7 Day Electronic Programmable Thermostat Heater
I have a Florida Geo heat pump 2 stage with no aux.heat. It is controlled by a Zone Perfect Two-Zone Unit hooked up to two Totaline P274-0300-C thermostats. Everything works great this way.
I was talked into buying a Honeywell VisionPRO TH8320U1008 to replace the Totaline on zone-1. They said the Honeywell can be wired for any system. Anyway, I can't take it back and I can't get it to work properly.
The Totaline is wired as follows BLK-0/W2/B RED-R BRN-C BLU-Y/Y2 YL-Y1 GRN-G WHT-W/W1. A total of 7 wires hooked up.
The Honeywell only calls for 6 wires to be hooked up in the 2H/2C Heat Pump mode with [no auxiliary heat] I hooked the wires up as follows BLU-Y2 RED-R/RC Note, R+RC are jumpered. BLK-0/B YL-Y GRN-G BRN-C. I stored the WHT wire. Wired this way the heat pump would work, but would not control the reversing valve when when calling for heat.
The Florida Geo heat pump has the the reversing valve energized in the cooling mode.
Any help with this problem will be greatly appreciated.
On the honey well tstat you have to go into the installer set up and set the swithover valve for energized in cooling
