  2. Carrier Comfort Network • Carrier Comfort Network (CCN)is a controls concept thatconsist of Carrier control products and Carrier equipment that are stand alone as well as designed to function together on a Digital Control System. CCN_BUS

  3. CCN BUS ARCHITECTURE CCN PRIMARY BUS • For General CCN Type Devices: Theoretical Maximum of 239 Devices on any bus. • For CCS type Devices: A Maximum of 32 33CS Devices or 8 Scanning Devices (Monitor Stat’s) on any bus. • This is a Local Area Network (LAN) not a Wide Area Network (WAN) (3 Conductor Shielded stranded wire cable 18 ga.) Comfort Controllers Or FID’s (CCN) TEMP (CCS) VVT (CCS) PIC (CCN) CIO (CCN) CCN_BUS

  4. CCN BUS ARCHITECTURE PIC’s Product Integrated Control • Is Factory Mounted On Carrier HVAC Equipment With Sensors • VAV Air Terminals • Air Handling Units • Chillers • Rooftop Units CCN_BUS

CIO M o d u l e • Some CIO’s: • Data Collection • Tent Billing • Auto Dial Gateway • Chiller Visor • Alarm Printer Interace • Loadshed Module • Flotronic System Manager CCN_BUS

  11. CCN BUS ARCHITECTURE The Key to the CCN BUS is Addressing: • An address is required of all devices on the bus. • No two devices on the same CCN system may ever have the same address. • A CCN and CCS address consists of a 3 digit bus number and a 3 digit device number. CCN_BUS

  12. Example Address: ( 024 , 127) Device Number Bus Number CCN BUS ARCHITECTURE CCN BUS is Addressing: • Legal bus numbers are 0 to 239 inclusive • The primary bus number is always “0” • Secondary bus numbers are 1 to 239 inclusive. • Legal device numbers are 1 to 239 inclusive. • A repeater module and NAM configured to work with a computer are not addressed.
