In 4-pipe applications, the Comfort setpoint (w) is in the middle of the dead zone,
between the heating and cooling sequences.
The dead zone can be adjusted via P055.
If manual changeover is selected, either the cooling sequence or the heating
sequence is released. In this case, the Comfort setpoint is at the selected heating
or cooling sequence.
