Unit ventilation mode

Parameters: Ventilation mode

Setting value: min (comfort = factory setting) / max (efficiency)

This parameter is used to set the operating mode for summer or winter.

In operating mode Summer (comfort), the fans run in an automatic operating mode or with the manually set ventilation level.

In operating mode Winter (efficiency), the fans run at ventilation level 1 (reduced ventilation) or the manually set ventilation level.

Ventilation level 1 (reduced ventilation) is automatically activated, if:

• in winter, the temperature falls below the temperature set with the outside air efficiency temperature min. parameter or
• in summer the temperature set with the outside air efficiency temperature max. parameter is exceeded. The conveying of warm outside air into the living spaces is reduced.
• LED III flashes. Intermittent ventilation (intensive ventilation with timer). After the time interval has elapsed, the ventilation unit switches back to automatic mode.

During operation in unit ventilation mode, higher ventilation levels can also be switched on manually, e.g. intermittent ventilation (intensive ventilation with timer). After the time interval has elapsed, the ventilation unit switches back to the unit ventilation mode.
