Gary your switch for the water heater is on the outside under cover on the water heater it self. I use a satelite. The cable that came with mine would not carry the satelite. Had to run new wire. I drilled thru the cabinet where I put the receiver, to outside & mounted a new satelite box. & ran it direct, to receiver. You should be able to use the cable connection that came on it for the T V upstairs. Hope this helps.
