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 efficiency of the heat exchanger and of the condensation produced in different climatic conditions, to help the installer or the designer
of the ventilation system to decide if to connect one or both condensation drainages.
High production of condensation is the direct consequence of a high efficiency level as well as of the humidity rate.
Table 6.c
indicates the sound level at the different speed.
