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.
Adjust the valves in all rooms until the required airflow for each room has been achieved.
Check the main airflows according to the instructions earlier in this procedure, as major
valve adjustment may greatly affect the main airflow.
During regulation, it must be ensured that the extract airflow is always at least 5% higher
than the supply airflow in order to create conditions for mass balance in the system.
