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.

CPP 60 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 40 seconds.
