Wyze thermostat HELP!

That’s a 120V oil boiler aquastat, it doesn’t have enough 24v power to run anything. You’ll need an external transformer to run the wyze. If you don’t have somewhere close to the thermostat location to install the transformer, then you can use a 24V relay and a 24V transformer in the boiler room. I have a thread detailing these connections here. Wyze thermostat simplified block diagrams - #10 by speadie
