Operation with an odd number of units
Carry out electrical connection on the Fan1 and Fan2 connections.
When connecting 3 or 5 ventilation units:
- connect the larger number of ventilation units (2 or 3) to the “Fan2” group and
- connect the smaller number of ventilation units (1 or 2) to the “Fan1” group.
When operating with an odd number of units, the volumetric flow required of the “Fan2” group is automatically compensated for by the “Fan1” group.
In cross-ventilation operating mode, ventilation units of the Fan1 group (exhaust air) are operated with a higher volumetric flow. Volumetric flow compensation is automatic in demand-driven automatic operation
