We've got a rental house we're fixing up to sell. Probably 15 years ago a previous owner converted a porch to an enclosed bedroom. He ran two furnace duct extensions from the basement, thru a garage, then up thru the floor. Just ahead of that, I notice a plug plugged into a 110-v outlet, that leads to a split, contacted by electrical twist connectors, that lead into the two added furnace ducts. One wire just goes through what looks like a little metal grommet. The other wire goes to the furnace duct thru what looks like a little solenoid-looking thing (about half the size of an automobile thermostat). It appears to even have miniature numbers ..or possibly a dial. (I know I'll at least have to clean up the connections for any electrical inspector that may see it before the sale). Any idea what these are? MB
