Volumetric flow per ventilation level
WS 170 … | Min. | Factory set | Max. |
|---|---|---|---|
Reduced ventilation RV | 40 m³/h | 60 m³/h | 160 m³/h |
Nominal ventilation NV | 40 m³/h | 90 m³/h | 160 m³/h |
Intensive ventilation IV | 40 m³/h | 120 m³/h | 160 m³/h |
The volumetric flow setting applies to both fans. With humidity protection ventilation, the fans run in intermittent operation. We recommend setting the volumetric flow for NV first.
The RV and IV volumetric flows are set automatically by the control on the basis of the NV reference value 1/3 less than (RV) and 1/3 greater than (IV).
Example: NV 90 → RV 60 → IV 120
The IV and RV control values can then be set manually.
Condition: Volumetric flow > Intensive ventilation > Nominal ventilation > Reduced ventilation.
