D0A Flow Rate Reduced Ventilation - Viessmann VITOTRONIC 200 Service Instructions Manual

Parameter group Ventilation
7D08 Set room temperature
Set extract air temperature for ventilation mode.
■ At extract air temperatures < "Set room tempera-
ture 7D08" minus 1 K, the bypass can be activated
for passive heating. The outdoor air/extract air is
not routed via the heat exchanger.
At extract air temperatures > "Set room tempera-
■
ture 7D08" plus 1 K, the bypass can be activated for
passive cooling. The outdoor air/extract air is not
routed via the heat exchanger.
