Mode of operation

The ventilation system is switched on with the mains fuse and started with ventilation level 2 and continuous ventilation with heat recovery operating mode.

RV 2 ventilation units run in push-pull mode and ensure a continuous supply of fresh air with heat recovery in operation with heat recovery mode. The cross-ventilation operating mode (without heat recovery) ensures that the rooms are ventilated in one direction.

In push-pull operation, there is a constant change from the exhaust air phase to the supply air phase and vice versa every 30 seconds.

To reverse the direction, the fan unit in each ventilation unit is rotated in a drum. When the ventilation unit is switched off, the air path is closed by a transverse drum.
