4.7.12 Setpoints and sequences
In changeover applications, the Comfort setpoints for heating and cooling
sequence are the same (w).
In 2-pipe applications with electric heater, the Comfort setpoint is either at the first
heating sequence (in heating mode) or at the cooling sequence (in cooling mode).
In 2-pipe applications with radiator, the Comfort setpoint is either at the radiator
sequence (in heating mode) or at the cooling sequence (in cooling mode).
The setpoints for Economy and Protection are below the Comfort setpoints (for
heating) and above the Comfort setpoints (for cooling).
They can be set via P019, P020 (Economy) and P100, P101 (Protection).

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.
