Move the ΔPa meter across the
extract air path as shown. This
example is based on the unit being
in operation mode A.
Adjust the extract fan speed, according the guide in the PC Tool on your computer .
The goal is to adjust the fan until the ΔPa meter shows the pressure drop value that was
read in point no 2, deducted a few percent, in order to create a small under pressure
inside the house.
Disconnect the ΔPa meter, as well as the computer. Adjust the balancing of the valves
in every room in order to make sure that the desired air flow rate can be supplied in
every room.
Check the nominal air flow rates based on earlier instructions in this procedure, as radi-
cal adjustments (balancing) will influence the nominal air flow rates.
