The CAD mode allows for users to incorporate AutoCAD* into the software for easy customization. This mode features automatic calculation of refrigerant piping length and size based on building layout, system check which ensures piping limitations are followed, and automatic selection of Y-joint and header sized per the system layout. It also generates a wiring diagram for selected Central Control options and provides a print out of equipment specifications, piping and wiring diagrams, and the total equipment cost.

The Sales mode allows users to customize their system based on the information specified. By selecting indoor units and providing accurate piping lengths, the system will help users utilize the combination ratio to pick the best outdoor units and provide piping sizes with corresponding lengths and additional refrigerant. The system will also provide the control and electrical wiring diagram, generate a wiring diagram for selected Central Control options, and delivers a print out of equipment specifications, piping and wiring diagrams.
