Braemar Adjust Capcity

When my Braemar unit was installed the capcity was reducted because I bought a bigger unit than I needed at the time. Now the the renovation is complete I want to adjust the unit to full capacity. I know the installer used the Specrolink controller to make the adjustment in the first place, but I think it's a hidden feature since it's not covered in the manual.

What is the difference between the system now and when it was initially commissioned...? Have extra outlets been added...? Do you have zones...? You will probably need someone back to commission it again as things have changed...
