At extract air temperatures < "Set extract air tem-
perature 7D08" minus 1 K, the bypass can be ena-
bled for passive heating. The outdoor air/extract air
is not routed via the heat exchanger.

Note
Further conditions must be met in order for passive
heating and passive cooling to be switched on: See
"Min. supply air temperature for bypass 7D0F" and
chapters "Passive heating", "Passive cooling" in the
"Function description".
