So to hopefully head off the safety patrol, I have a friend who's an electrician and he has agreed to check my work before final hookup. I'm installing a 240v heater in my workshop and would like to control it with a Wi-Fi thermostat instead of a line voltage model. YouTube has let me down a bit in that the videos I've found on modifying the heater for a 24v control circuit have been contradictory and confusing. I thought maybe someone here would have done this already and could point me towards some reliable diagrams. I'm hoping to get as much done as possible myself before pestering my buddy, his time is pretty hard to come by. Thanks!
