6.1 Setting Fan speed

The speed of the unit can be adjusted during installation according to required ventilation rate. 

Figure 6.a 

below shows performance curves (for supply air and extract air) at different settings of the 0-10V signal to the motors. Airflow and consumption 

refer to one single motor. 

Table 6.b

 indicates the sound level at the different speed.
