Minimum distance

The adjustable parameter "minimum distance between heating and cooling"
is enabled with both dependent and individual setpoints.
The minimum distance is always between "heating setpoint comfort mode"
and "cooling setpoint comfort mode". It acts as a buffer zone to prevent
the two setpoints from overlapping.
Example:
Individual setpoints are selected. "Heating setpoint comfort mode" is set
to 21 °C and "cooling setpoint comfort mode" is set to 26 °C. The dead zone
between heating and cooling is 3 K. If the heating setpoint is moved up,
the dead zone is also moved up. If the adjustment exceeds a temperature
of 23 °C, "cooling setpoint comfort mode" is also adjusted up to ensure that
there is always a minimum distance of 3 K between heating and cooling.
If the cooling setpoint is moved down, the dead zone is also moved down.
If the adjustment exceeds a temperature of 24 °C, "heating setpoint comfort
mode" is also adjusted down to ensure that the minimum distance is also
retained in this case.
