I just bought my condo this summer and have a very old boiler (37 years and counting… part of the reason I wanted Wyze was to monitor output and have a better sense of when it was dying). I hooked up the wires:
Rh - Rc
W - W1
C - C
And it didn’t power on. There was a connecting wire from Rc to Rh on the original thermostat, but dropped it per instructions. I also noticed there’s a wire splice from my furnace to my thermostat so I’m hoping that is not messing up the wiring too much. Any suggestions would be helpful. So far I’ve just gotten a “rewire it” which I would like to not do if possible.
That’s an aquastat, you will need an external transformer to power the wyze, there is not enough power available from the transformer in an aquastat to run a wifi thermostat.
Connect a 24V AC wall thermostat adapter to Rc and C and connect the Wire that is currently connected to R to Rh, and the wire that is currently connected to W to W1 on the wyze.
If you have already started to setup the wyze, you will need to either restart from the beginning, or add a new thermostat, and ignore the partially setup one, depending on how far you got. Tell it you have the following wires during setup: Rc, C, Rh, W. You will not need the wire that is currently connected to C, put a wirenut on it to cap it off, and wrap it in electrical tape to prevent it from shorting against anything else.
