Description
The Lennox 79J73 is a Control Limit, an essential component in the HVAC systems, that are used to control the operating temperatures within heating equipment. This product is designed for use with several different Lennox furnaces and is used to prevent the temperatures from getting too high and thus the heating cycle is stopped when necessary. It works through reading of temperature from the furnace and tripping off a switch for the heating element when temperatures have risen to certain levels.
