What is a Differential? The difference between on and off setpoints on a control. For temperature, it is the difference in degrees between the thermostat's on and off setting. If you set a heating thermostat with a 3 degree differential to 71°, it will supply power at any temperature below 71° and cut off at 74° (3 degrees above the setpoint). A cooling thermostat would cut on above 71° and off at 68°.
