As you are choosing the best product for your application, you will notice that we talk a lot about line voltage temperature differential, or hysteresis, with our thermostats. So, what is temperature differential? When a switch changes states from Open to Closed. The difference between those two points is the differential, or hysteresis. Here’s an example for line voltage thermostat differential…
A line voltage thermostat 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 the line voltage thermostat is 5°F. Different thermostats can 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 and your application. If not, it could fail to keep your application at the right temperature, or fail overall.
