After waiting months to attempt to install the Wyze Thermostat (because after reading reviews I did not want to be without heat during the cold months), I discovered the control board in my furnace only has a R, G, W connector. There is nowhere to connect the yellow or blue. The current programmable thermostat has a G, Y, W, RH and a jumper between RH and RC. The R, G, W from the thermostat all go to the respective connectors on the Controller Board. There is a Blue wire that is not connected to the Thermostat and not connected to anything on the Board end. The yellow from the thermostat is connected directly to a red wire (2 wire cable in brown sheathing) that goes to the Central Air Compressor outside. The other wire coming from the Central Air Compressor is white and is connected to a green wire with a wire tie. This green wire then connects to a bare copper and green wire with a wire tie. The other green wire from this connected appears to be connected with a blue wire to the frame of the blower as a ground.
I am not really sure how to connect the yellow wire coming from the thermostat and if I should do anything with the white wire coming back from the Central Air compressor.
I am thinking that maybe the adapter would be used and the yellow wire would go to the adapter and then the red wire going to the Central Air would be connected to Y wire from the adapter. I’m not sure what to do with the c wire coming from the adapter. I am thinking the R, G, W wires would go to the adapter and then to the R, G, W on the Control Board.
Has anyone dealt with something like this?
