The older Carrier systems...GEN1, 2, & 3 plus the newer Carrier Comfort products are very complex.
Advice here would to be not fool around with it unless you have been trained and have adequate experience. I seen plenty of CCN systems that are messed up b/c the installers/servicers do not understand the system.
Having the software simply enables an individual to change parameters. This is a mistake if the serviceer does not have a full understanding of how both VVT & VAV systems differ and should operate, understanding the applications of zone dampers, series boxes, parallel boxes, etc.
CCN is great however b/c so many attempt to work on them/install them w/o the proper knowledge, many customers literally hate CCN.
