3.6.9 Setpoints and sequences
Comfort setpoint (w) is in the currently active heating or cooling sequence.
∂
If the supply air temperature is available (via KNX), the air
flow may also increase when the room temperature is
below the heating setpoint
∂
If no supply air temperature is available, the sequence for
air flow control is cooling only
The setpoints for Economy and Protection mode are below the Comfort setpoints
(heating) and above the Comfort setpoints (cooling).
They can be set via P11, P12 (Economy) and P65, P66 (Protection).
