and press enter� The DucoBox Energy Comfort
(Plus) calibration mode starts up� Do not start manual calibration until you see the
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 Comfort (Plus)� 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 (Plus), the 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.
