Control characteristics

The hysteresis controller is factory-set. The hysteresis value influences the
starting and stopping point for "Heating" or "Not heating".
Example:
Set room temperature: 21 °C
Hysteresis: 0.6 °C
Heating stops as soon as the actual
room temperature exceeds 21.3 °C.
Heating starts as soon as the actual
room temperature falls below
20.7 °C.
You can change the control character-
istics by changing the hysteresis
value. In the delivered condition, the
hysteresis is set to 0.6 °C. Select a
lower value if your system responds
too slowly.
