Forc: this item is displayed only when the unit is stopped locally (LOFF). selecting this item authorises turning on the
pump with no delay and for an unlimited length of time. The pump will remain on until any button of the user interface is
pressed: it is then immediately stopped. If the unit is in CCN control, then the pump status is displayed in turn with “Forc” if
