Technical Manual Glass Room Temp. Contr. SCN-RT1Gx.01
6.4.4.1 Hysteresis
The setting of the hysteresis is used for calculating the points of switching on and off. This occurs
under consideration of the current adjusted setpoint.
Example: The controller is adjusted as heating with and a basic comfort setpoint of 21°C and
a hysteresis of 2K. So the controller switches the control value, at the mode comfort, on at
20°C and off at 22°C.
To note is that a big hysteresis generates big differences of the room temperature. A small hysteresis
can generate an almost permanent switching process, because the points for switching on and off
are very close to each other. This can generate a fast consumption of the control value.
