    Turn on switch 1 and then wait for an hour. Shut off switch 1, then immediately turn on switch 3 and open the door. Touch the light. If the light is off and hot, switch one controls it. If it's off and cold, switch 2 controls it. If it is on, switch 3 controls it.

    I'm on both COM01 Steam Boiler and COM02 Firebox. If I have to choose one, my preference is for Firebox.
