3.6.8 Setpoints and sequences
On changeover applications, the Comfort setpoints for heating and cooling
sequence are the same (w).
On 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).
The setpoints for Economy and Protection mode are below the Comfort setpoints
(heating) and above the Comfort setpoints (cooling).
They can be set via parameters P11, P12 (Economy mode) and P65, P66
(Protection mode).
