There is a circulating pump. I know how to wire it. Also the boiler is controlled by an aqua stat for the glycol temp. The thermostat and contactor I’m asking about are for the room temperature.
I have a homemade boiler, it has two 4500w elements. I want to wire a line voltage thermostat to a contactor to control room temp with in floor heat. What is the correct way to wire it?
