Hysteresis algorithm uses a temperature difference (against setpoint temperature) to switch heating device ON and OFF. If thermostat works over
hysteresis and it is used in a slow response system (e.g. underfloor heating), cycles of underheating and overheating cannot be avoided. It is difficult to
maintain a constant temperature in the room because the thermostat is activated when the temperature drops below the setpoint temperature. In a
system with high thermal inertia, the room temperature may still drop after the thermostat is turned on. Conversely, the thermostat switches off when
the temperature is higher than the preset temperature. After the thermostat is turned off, the room temperature continues to rise because the heated
concrete floor has to give off heat to the surroundings. The hysteresis value can be changed in steps of 0.1 from ± 0.1°C to ± 0.5°C - the lower the value,
the thermostat will react faster to temperature changes in the room. For example, if you set the temperature to 20°C and if the hysteresis is 0.5°C, the
heating will be turned on when the temperature drops to 19.5°C and turned off when the temperature reaches 20.5°C.
From this point on, the thermostat will start working according to the hysteresis set on the internal or external sensor.
How to set the hysteresis on the internal or external sensor:
Select „Settings”.
Select „Settings”.
Select the „Hysteresis” option.
Use the slider to select hysteresis value.
