CCN Communicating RTU Supply Air Sensor (Use PremierLInk for non CCN communicating RTU) Communication Bus 20/3/shielded cable (See Notes 1,2) 120vac 24vac 40va 24vac 40va 24vac 40va 24vac 40va (See Note 2) Primary Air Sensor Duct Sensor (Locate upstream of damper) 24vac 40va 20/2/s cable (See Note2) (See Note 5) System Pilot 20/3/s cable (See Note2) Bypass VVT Linkage Master (See Note 3) VVT Zone VVT Zone CO2/T55/56 (Optional for DCV) (See Note 2,4) (Optional For Master) T55/56 T55/56 T55/56 Typical 3V VVT System

  4. Typical 3V VVT System Notes • Notes: • 239 devices maximum per bus. Repeater required every 1000’ or 60 devices. Maximum of 3 repeaters per bus. • Communication bus and sensor wiring MUST be separate from AC power wiring • Maximum of 8 Masters per bus. • Combination CO2/T55/T56 sensor may be used in place of T55/56 on any zone requiring DCV. RTU must be capable of controlling economizer for DCV conditions. • Locate PAT in supply air duct from air source unit.
