EXHAUST CHECKING:
Remarks
In automatic mode, remove all BXC hygro modules in order to set them at the
max airflow point (max opening).
- Measure each BXC airflow (must be registered in the commissioning
document) and check measured airflow is compliant with theorical airflow.
BXC1 max airflow
BXC2 max airflow
BXC3 max airflow
BXC4 max airflow
- Check the sum the amount exhaust airflow (full opened BXCs +
Compensation valve) is compliant with the exhaust airflow displays on the
synoptic (+/- 20%).
This test allows to assess the air leakages in the Exhaust network. If too many
spillages, check the exhaust ductwork.
Then, place again the hygro modules in each BXC and clip the front cover.
Unclip the hygro module to make the mobile damper fully open (BXC at its max airflow)

SUPPLY CHECKING
Remarks
In boost mode, after 5mn (regulation stabilisation) check on the synoptic
the compensation valve is not fully closed. If the compensation valve is fully
opened, remove on 1 BXC the hygro module in order to set it at the max
airflow point (max opening). So, the compensation valve shouldn’t be fully
opened anymore.
- Measure each pipe airflow and check measured airflow is compliant with
theorical airflow.
Pipe 1 max airflow =
Pipe 2 max airflow =
Pipe 3 max airflow =
Pipe 4 max airflow =
Pipe 5 max airflow =
Pipe 6 max airflow =
Pipe 7 max airflow =
Pipe 8 max airflow =
- If measurements are not compliant with max airflows (28m
3
/h +/- 20%),
change in the WIZARD the pipe length (Short / Medium / Long) and if too
many airflow, use a piece of foam glued into the pipe to reduce max airflow.
And measure again all the 8 pipes.
- Check the sum the amount supply airflow (measured at the end of each
supply pipe) is compliant with the supply airflow displays on the synoptic
(+/- 20%).
This test allows to assess the air leakages in the Supply network. If too many
spillages, check the exhaust ductwork.
