Hi,

I attempted to wire up the Wyze thermostat. However, I have not been able to get it to work with my air conditioner and the cooling function. The fan did blow air but it was not cool. The outside unit was also on with the Wyze thermostat. When I wired up my old thermostat, the air conditioning worked perfectly.

Can someone please help?

Thanks!

Do you have the picture of the old thermostat wires connected before the install?
