 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.

must only be adjusted at the vents themselves. Adjusting vents will not alter the flow of 

previously calibrated vents�
