Due to the time profiles stored, the weekly programme mode controls the air performance for supply and extract air.

Weekly programme P1 is factory-set. This can be adjusted only with the help of the profi-air cockpit 

app, the profi-air cockpit pro software, or the optional wireless remote control.
