Volumetric flow of ventilation level

Setting values
● Level 1: 20 m³/h
● Level 2: 30 m³/h
● Level 3: 40 m³/h (nominal ventilation NV)
● Level 4: 50 m³/h (intensive ventilation IV)

For levels 2 to 4, a minimum of 21 m³/h and a maximum of 70 m³/h can be set. The setpoint volumetric flow setting applies to both fans. We recommend setting the volumetric flow for (NV) first.
