=== Hysteresis ===
A thermostat allows to define the target temperature called the setpoint (eg: 25°C) and use an hysteresis range (EG: 2.5°C) to avoids continuous state change around the target temperature.
[[Fichier:heater-hysteresis.jpg]]
With the hysteresis, the heater starts heating from 25-2.5 = '''22.5°C''' and will stop heating when the temperature raised above 25+2.5 = '''27.5°C'''. The temperature will slowly decrease and the heater will start again when temperature falls under 22.5°C.
=== Forced Mode ===
Forced state is canceled when the temperature reach the setpoint temperature corresponding the forced state.
