1.4 Functional description
Recirculation module for 100 % recirculation of the extract air into the building. Multi-leaf dampers are also required
for recirculation operation. The module consists of a recirculation damper including drive. The recirculation module is
installed between the heat exchanger segment and the supply air segment of the AIR1 RH ventilation unit.
If the unit is in "recirculation regulation" mode, the multi-leaf dampers close automatically. It must be ensured that the
multi-leaf dampers are properly installed for this reason.
