Description
The Lennox 66463 Relay Potential is parts used in most HVAC systems that include furnaces and air conditioners. It works like a switch, controlling the amount of electricity that is to be supplied to the various parts of the system depending on instructions from your thermostat. When the thermostat senses a change in temperature and sends a signal, the relay potential sets off the right response, including switching on the furnace or air conditioner to regulate the temperature indoors that you prefer. A well-working Lennox 66463 Relay Potential helps to regulate the temperatures in your home and keep your HVAC system running smoothly.
