HINWEIS

ºº

NOTE

In the event of a power failure or if the ventilation unit is
switched off, the filter time is not reset.

Bypass

The bypass directs the outside air past the heat exchanger and
directly into the building. Heat recovery is deactivated. In sum-
mer, this function can be used to direct cool outside air (e.g. at
night) into the rooms.

Sensor

The control sensitivity of the connected air quality sensors (op-
tional) can be changed in a range of -10…0…+10.
The sensitivity can be increased, e.g. for a duct sensor
(+1…+10), or decreased e.g. for a room sensor
(-1…-10). The factory setting is 0.
