Comments about White-Rodgers F145-1328 White-Rodgers Remote Indoor Temperature Sensor:
It's great. Just drop a wire down and hook it up. The thermostat picks it up when you turn on the little setting for it. Great. Keeps my son's room warm. Before it would get 3 or 4 degrees colder than the rest of the house. His room is a corner and has no insulation in the walls.
