I bought a few wyze thermostat some time ago and they have been working great.
I used them to replace the previous “dumb” thermostat that control my gas furnace (and radiators).
Wiring on prev thermostats were R and W.
I needed to add power so the new setup is
RC and c (new wire) and Rh and W1 (existing wire)
The 2nd thermostat was easier as power was already here:
RC + W1 + C
I also have Central air for cooling and never figured out how to add it to these 2 wyze thermostat. So I keep using the old thermostat for the AC only. (Y + G + Rc)
So I have 2 options:
1- Unplug the heat in summer, plug AC and revert in winter
2-hope the wyze community can help me figure out how to have the 2 systems plugged in.
