VVT® pressure independent system overview
Pressure Independent VVT systems are used when the air-
flow into the zone is critical and must be maintained. With
a pressure independent strategy, zone damper position is
modulated to maintain zone airflow at a cfm flow rate
calculated by the controller, based on space temperature
variation from set point. Therefore, even though the sup-
ply duct static pressure changes, the airflow volume at the
zone remains constant.

NOTES:
1. 239 devices maximum per bus. Repeater required every 1000 ft or 60 devices. Maximum of 3 repeaters per bus.
2. Communication bus and sensor wiring MUST be separate from AC power wiring.
3. Up to 32 total zones per system. Maximum of 8 Linkage Coordinators with a total of 128 devices per single bus.
4. Combination CO

/T55/T56 sensor may be used in place of T55/T56/T59 on any zone requiring DCV. RTU must be capable of controlling
economizer for DCV conditions.
5. Locate PAT in supply air duct from air source unit.
6. VVT zone controller is required for Linkage Coordinator functions if all zones are pressure independent.
7. System Pilot can share power with Bypass Controller or VVT Zone Controller.
