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.

6.2 Before Starting the System
When the installation is finished, check that:
• Filters are mounted correctly.
• The unit is installed in accordance with the instructions.
• The unit is correctly wired.
• Eventual outdoor and exhaust air dampers and silencers are installed and that the duct system is correctly connected to the unit.
• All ducts are sufficiently insulated and installed according to local rules and regulations.
• Outdoor air intake is positioned with sufficient distance to pollution sources (kitchen ventilator exhaust, central vacuum
system exhaust or similar).
• The unit is correctly set and commissioned.
