10.2.3. Operating principle
The pump operates independently as soon as the central ventilation unit is switched on. It is equipped with a level
controller that automatically switches the pump on and off depending on the level of condensate in the tank.
As standard, the pump incorporates a dry NC contact (normally closed) which opens when the water level in the
condensate tray reaches a critical level, see XVIII GENERAL WIRING DIAGRAM. This contact is used to control the
operation of the ventilation unit in case of abnormally high condensate levels and thus protect the equipment as well as
occupants and staff.
