enter image description hereHarper gave me a great answer on how to connect my Lambert high intensity heater to a thermostat in general but I have a follow up question and don’t know how to attach that to my original post so I am creating a new question.
My heater has a transformer connected to the control box and is running blue and yellow wires that attach to the blue and white connectors respectively on the control box. However I have an empty red wire connector on the control box which I assume is for the thermostat but I don’t know where to connect the thermostat’s white wire. Can anyone please help me with this question? Thank you
