I’m having issues installing my new wyze thermostat and am hoping someone here will be able to help me out. Then I connect the thermostat the screen does not turn on and it repeatedly clicks. Here is what I’ve done:
Old thermostat wiring:
My old thermostat did not have a c wire so I had to use the c wire adapter. My furnace is about 20 years old and the wiring at the control board was a mess. I was able to locate the w, g, and r wires terminals on the control board.
… But there was no c terminal and my thermostat wires were connected via wire nuts outside on the furnace.
I was able to trace the wires from the board to the wire nuts and connect the w, g, r wires to the adapter but I wasn’t sure what to do with the c wire. I connected it to the 24ac terminal on the board (seen on 2nd picture I posted).
I checked the voltage with a multi meter at the new thermostat and was able to measure 27 volts from the red to white, red to yellow, and red to green (labeled c).
Can someone please help point me in the right direction? Thank you!
