On 4-pipe applications, the Comfort setpoint (w) is in the middle of the dead zone,
between the heating and cooling sequence.
The dead zone can be adjusted via parameter P33.
If manual changeover is selected, then either the cooling sequence or the heating
sequence is released. In this case, the Comfort setpoint is at the selected heating
or cooling sequence.
