In the ‘Adjust the supply vents’ step, select the duct with the highest flow rate
and resistance and, using a pressure-compensated air flow meter, measure the
flow rate at this vent� If the flow rate is too high or too low, you can adjust it using
the arrow keys on the DucoBox Energy Comfort� Depending on the user controller
version, this can also be done by pressing the (lower) and (higher) buttons on
a paired user controller� Adjust the flow rate so as to obtain the desired flow rate at
this vent� The flow rate can be fine-adjusted at the vent�
NOTE
: The system needs around ten seconds to run stably when adjusting the
flow rate using the buttons on the DucoBox Energy Comfort, User controller or
making large changes at the vent. The system will indicate when the calibration
is stable. The flow rate cannot be measured correctly until after this time has
elapsed.
