Put the carrier unit back on the wall and connect the colored wires to the designated terminals.
R-Red, G-green(fan), Y- yellow and so on until they are all reconnected.
Manufacturers controls are designed to operate their units and sometime have more control options that require the extra wire you experienced with the off brand unit you purchased. Take it back and get the instruction manual out for the Carrier unit and learn to like it. If you have aZone System it is the only cotrol that will work with your system.
