Reliable bypass control for stable, energy‑efficient VVT system performance
The i‑Vu® VVT Bypass II Controller (OPN‑VVTBP‑02) provides factory‑engineered control for VVT bypass applications, delivering accurate pressure regulation, equipment protection, and seamless integration with the Carrier i‑Vu® Building Automation System.
Product Integrated Controller
The VVT Bypass II controller is used to regulate the supply duct static pressure for a variety of pressure-dependent VVT applications and allows constant volume HVAC equipment to provide zone level temperature control. This advanced controller features a separable, brushless actuator and an integral pressure sensor for reliability and longevity. It also features native BACnet communications and plug-and-play connectivity to the Carrier i-Vu Building Automation System.
BACnet Advanced Application Controller (B‑AAC)
(BACnet 135‑2012 Annex L, Protocol Revision 9)
BACnet MS/TP via EIA‑485 or ARCNET (DIP‑switch selectable)
Local access port for startup and troubleshooting (115.2 kbps)
1 analog input: Discharge Air Temperature (10k thermistor)
1 analog output: 0–10 VDC for VFD or actuator control
Brushless DC actuator, 45 in‑lb torque, 205‑second runtime (90° travel)
Integral pressure sensor: 0–2 in. H₂O, ±5% accuracy at full scale
It regulates bypass airflow to maintain stable duct pressure and protect VVT airside equipment during changing zone demand conditions.
Discharge temperature protection logic minimizes heating or cooling lockouts caused by unsafe air temperatures.
Yes. A built‑in precision differential pressure sensor measures airflow pressure accurately.
Facilities that need:
