Meh. Sometimes an idiot light is convenient. I designed 5 idiot lights in my air conditioner so it tells me whether it has a drain problem, a fan motor problem (two motors), or a Freon problem (High pressure safety-out or Low pressure safety-out).What kind of 240 volt equipment are you powering that doesn't indicate it has no power and needs a secondary indicator to show it is not working?
