7. Calibrating flow rates
Close all windows and doors. Ensure that all duct openings in the DucoBox Energy Premium are fully closed
and that the DucoBox Energy Premium cover is closed. Avoid air leaks in the ventilation ducts. Open all
interior doors between the various zones.

message on the display and follow the instructions on screen. Enter the flow rates
for each zone if asked to do so.

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 Premium. 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 Premium, User controller or making
large changes at the vent. The flow rate cannot be measured correctly until after
this time has elapsed.
