ACCELERATED SHUT-DOWN
Parameter
number
Description
Accelerated shut-down is used to switch over more rapidly from the Comfort set point to the reduced set
point, keeping the heat pump off.
The function keeps the heating system off until the room temperature reaches the reduced set point or the
frost protection set point.
When reaching one of these set points, the pump and/or the mixer valve in the heating circuit are reactivated.
During the accelerated shut-down phase, the pump in the heating circuit is not operating while, in the case of
circuits with radiant panels, the mixer valve is completely closed.
