Hi my Wyze thermostat does not offer me any cooling options, the fan would not turn on as well. During setup it had detected additional wires that I had not connected so I skipped after a couple of retries.
I will attach Wyze Thermostat wiring pic (please ignore my labels), pics of the old thermostat and the wiring in the control board.
The blue wire seems to be c wire since it has 26 volts with respect to red wire.
the Y1 terminal needs to be wired for AC control. I see on your control board you have 2 wires on Y/Y2, I suspect once of them run out to your outside condenser, do you know where the other runs?
@speadie may be able to recommend a solution
Thank you. It appears that the blue wire at thermostat is actually connected to y on the control board. Pic attached, I will try and reset the thermostat and post back. Please feel free to let me know otherwise meanwhile if that is not the best step.
Ahh, nice. Yeah, reset & delete from app & start over, wiring the blue wire to Y. Just know you’ll need to install the C wire adapter unless you have a spare wire to use a C.
There is a good news and a bad news.
Everything seems to work except for the temperature display. It shows its 32 degrees (F), which is by a big margin incorrect in either unit. It has been that way for half an hour now.
Looks like it is time to replace the unit.
Thank you for your useful help anyways.
