So, I have the thermostat installed, it powers on, and during the test, phase 2 of the heating does not come on. Originally there was a 6 wire thermostat with no C wire connected. It was only Y,Y2,W,W2,G and Rc. So I tried the C conversion device, and everything worked, except stage 2. So I ran an 8 conductor, and hooked up the C wire as well. As it stands, this is how the thermostat is hooked up:
Your wiring looks correct on both the furnace and Wyze thermostat. During setup, did you choose “Gas” for the type, then “Forced Air”? Push the knob and hold for 10-15 seconds to prompt a reset of the thermostat. Delete it from your app, and re-add it with your new wiring and see if it detects the correct wires.
I did that, and re-added it in the app. Still the same issue.
Update: I just saw another post that showed setting stage 2 as electric, so I tried that, and it is now working. Is that ok, or should it be working properly with propane and forced air as stage 2?
Stage 2 is still not working properly on they wyze. It should start with a stage 1 (W1) call for at least 15 seconds and then also switch on stage 2 (W2). This will cause most furnaces to switch into stage 2 heat. Right now, the wyze turns off stage 1 (W1) when it turns on stage 2 (W2), which confuses most furnaces and they just shut off.
Agree that is how the System Test is working. W1 working. W2 not. That said, I am noticing that after 30 mins on Stage 1 … my furnace is bumping into Stage 2 and off when set point achieved. I spoke to my HVAC installer, and they said that I could disconnect the W2 to thermostat, jump W1/W2 at furnace board, and let the furnace control W2 - w/ dip switch control of 10, 15 or 20min delays to W2. Or leave connect to the Tstat and let it control. So I have W2 connected to Tstat, and then after 30 mins, W2 kicks on. I haven’t checked if Wyze Tstat is energizing W1/W2 when this occurs, but assuming so. It must be doing something, but not sure if it’s intentional. @Chuan is this correct? Thx!
