4.4 Setpoints and sequences
4.4.1 2-pipe and 2-stage applications
On changeover applications, the Comfort setpoints for heating and cooling
sequence are the same (w).
On 2-pipe applications with electrical heater, the Comfort setpoint is either at the
first heating sequence (in heating mode) or at the cooling sequence (in cooling
mode).
On 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 Energy Saving and Protection mode are below the Comfort
setpoints (heating) and above the Comfort setpoints (cooling).
They can be set via parameters P11, P12 (Energy Saving mode) and P65, P66
(Protection mode).
