Description
The Lennox 49L87 200-230F Auto Limit Switch 3 Inch Insert is among the safety devices in HVAC systems used to control and measure temperature in heating appliances. This switch used with furnaces and other heating units turns on or off the heating system depending on the temperatures set at the range of 200°F to 230°F. Its main function is to protect the heater from overheating and, therefore, shut down the circuit once the temperatures go high. In maintaining acceptable temperature standards, the 49L87 Auto Limit Switch reduces the risk in the HVAC system and its environment, hence excluding the chances of equipment failure or explosion.
