Is the Hunter 42204 replaceable with the Nest Thermostat. I have tried to identify the wires based on online articles but being largely electricity challenged I cannot be sure enough to order the Nest Thermostat. I have taken photos but cannot get a good angle to photograph the wiring from the opening on the sides. Am afraid to tug the cover for fear of loosening something. Next to the Hunter thermostat (which turns on just the furnace and allows programming of the temp) is a separate manual circular Honeywell controller for one HVAC and an identical one upstairs controls the second HVAC (2nd and 3rd floors). There is also a manual circular Honeywell controller that controls the heat for the house addition. In summary a Hunter and a Honeywell thermostat to control heat and two Honeywells to control two HVACs. If compatible with all these how many Nest thermostats do I need if compatible? Hoping to take advantage of Black Friday sales.
