As you are choosing the best product for your application, you will notice that we talk a lot about temperature differential of a line voltage thermostat, or hysteresis. So, what is temperature differential? A Line Voltage Thermostat Differential is when a switch changes states from Open to Closed. The difference between those two points is the differential, or hysteresis.

With a line voltage thermostat, it kicks your fan on once air temperature rises to 70°F (contacts close), and once the air temperature falls to 65°F the fan turns off (contacts open). Given this example, the differential of this thermostat is 5°F. Different thermostats could have different options for temperature differentials, so it’s good to evaluate what the thermostat is capable of to ensure that it will work for you.

Tempro Thermostats Temperature Differential

Line Voltage Thermostats Differential

Our line voltage thermostats are available with a fixed or adjustable temperature differential. Our fixed line voltage thermostats have a hysteresis of 2°, and if the application requires a wider range we offer an adjustable model up to 12°F.

Additionally, our electronic temperature controller offers an adjustable differential up to 30°F.
