About Fan and Limit Controls
In many commercial and industrial operations, it’s important to regulate and limit temperature levels for fans, furnaces, HVAC systems and other types of machinery that generate heat. Fan and limit controls are designed just for these purposes, preventing the fan from starting until a certain temperature is reached, and then also shutting off the gas or heat source if the fan fails to start or malfunctions. Thermostats, along with fan and limit controls, help you maintain safe, comfortable conditions in your workplace or residence—while also prolonging the lifespan of your heater or other piece of temperature-regulated equipment. In addition to fan and limit controls, you can also shop for HVACR and appliance controls.
