Wyze Thermostat A/C issues

Hello everyone. I am having some issues with my Wyze thermostat. I am following all the instructions but it will not turn on my compressor.

This is my current setup. It is a simple Trane thermostat. It works perfectly fine.

This is my setup following Wyze’s instructions.

I have an Ecobee thermostat upstairs (separate system but identical wiring that I replaced the same trane thermostat that is downstairs). The wiring is below and it works perfectly.

Notice how the orange wires are different. When I swap the orange wire on the Wyze thermostat, it still doesn’t turn on the AC compressor.

Can someone please help me. I really want this to work so I don’t have to buy another $300 ecobee.

Thanks!

What happens if you put the yellow wire on Y2?

That didn’t work :frowning:

Do you have a heat pump? Orange wire is typically for a heat pump. When you swapped the orange wire, did you reset the thermostat and start over telling the app you have a wire on O?

I live in FL in a newer home (5 yrs old). I have two Lennox Merit Series 2 ton, 1 stage heat pumps outside my house. One for upstairs, the other for downstairs.

I have reset the thermostat multiple times in the app. It still does not work.

Ok time for some investigating if you’re up for it.

Do you have a multimeter and two pairs of alligator clips? If so, take the wyze thermostats off and measure continuity between a few terminals.

I don’t have a Wyze thermostat but I know how thermostats should be working.

Tools:

1 Multimeter
2 alligator clips
The thermostat and your phone
Patience and caution.

Steps:

  1. Clip Rc and C from the wall to your thermostat to power it up and leave everything else disconnected.

  2. Verify that you can see your thermostat in your app as connected. Try not to physically move the device and don’t try to read the screen.

3.Using the app, turn on your AC by lowering the temperature. If your thermostat is working properly, you should hear a relay click.

  1. Measure continuity between Y1 and Rc.

  2. Measure continuity between Rc and G

If everything is working well, you should get continuity between the terminals listed above. If not, submit a bug report to wyze letting them know on as much detail as you can what isn’t working (no continuity between Rc and Y1 when in AC mode) and request a warranty replacement.

Hopefully this helps you or someone else experiencing similar problems.
