Hysteresis Setting
The room thermostat hysteresis setting determines how often or with how many degree differences the room thermostat will attempt to reach the desired temperature value. The hysteresis setting can be described as the operating sensitivity setting. The factory operating sensitivity of Room Thermostats is 0.5oC. This setting determines the difference between the set temperature on the room thermostat and the current temperature in the room. Operating sensitivity can be changed with hysteresis positive and hysteresis negative settings.
*When the operating sensitivity is 0.5oC, if you set the desired temperature to 23.0oC, your heating unit stops when the room temperature rises to 23.5oC, and your heating unit starts when it drops to 22.5oC.
