Description
The Lennox 56W21 Limit Switch 160°F-30°F is an essential part of HVAC systems. Intended to control temperature, it provides safety by avoiding excessive temperatures. This switch operates by sensing the temperature of the system and breaking the circuit if the temperature rises beyond the limit which is usually between 160°F to 30°F. This switch is used on furnaces and boilers, where an accurate control of temperature is desired for operation efficiency and safety. It encompasses the protection of some equipment from getting damaged, its fuel conservation, and its capacity to make occupants comfortable by controlling the room temperatures.
