i-Vu® VAV Zone II Fan Terminal
OPN-VAVB3-02

Product Integrated Controller

The VAV Zone II Fan Terminal controller provides zone level temperature and air quality control for a variety of pressure-independent VAV applications. This advanced controller features a separable actuator for easy installation onto fan-powered or single-duct air terminals. It also features native BACnet communications and plug-and-play connectivity to the Carrier i-Vu Building Automation System.

Application Features

  • Sophisticated factory-engineered and tested control programs provide reliability and energy efficiency
  • Supports modulating hot water, 2-position hot water, single, 2, or 3 stage electric heat, or zone perimeter heat
  • Built-in advanced control routines for zone level humidity control or zone level demand control ventilation (ASHRAE® 62)
  • Adaptive optimal start and PID control for maximum occupant comfort
  • Supports Carrier communicating space sensors, which allow for local setpoint adjustment and local overrides
  • Quick and easy test & balancing process

System Benefits

  • Integrated Carrier airside linkage algorithm for plug and-play integration with Carrier air sources
  • Fully plug-and-play with the Carrier i-Vu Building Automation System
  • Supports demand limiting for maximum energy savings
  • Compatible with i-Vu Tenant Billing for tracking tenants’ after-hours energy usage

Hardware Features

  • Separable brushless actuator for reliability and longevity
  • Capable of system or stand-alone operation
  • Native BACnet MS/TP or ARCnet communications
BACnet Support Advanced Application Controller (B-AAC), as defined in BACnet 135-2012 Annex L Protocol rev. 9
Communication Ports BACnet Port: EIA-485 port for BACnet MS/TP communications (9600 bps, 19.2 kbps, 38.4 kbps, & 76.8) or ARCnet 156 kbps;
Local Access Port: For system start-up and troubleshooting (115.2 kbps);
Rnet Port: For connecting Carrier communicating room sensors and Carrier's touchscreen user interface;
ARCnet Port: For connecting the actuator cable
Integral Actuator Brushless DC motor, torque 35 inch-pounds (4Nm), runtime 205 seconds for 90 degree travel during control.
Integral Pressure Sensor Precision low flow AWM series O-2 in H2O, sensitive down to +/-0.001 in. H2O. Barbed tapered airflow connections accept 3/16 in. (4.75 mm) ID tubing. Allows for readings across the 0-2 in H2O range, accurate to +/-5% of full flow at 2 in. H2O.
Inputs 3 analog inputs: RH/CO2 (0-5V), T55 (10k thermistor), SAT (10k thermistor). AIs have 10 bit A/D resolution.
1 binary input: Remote Occupancy (dry contact).
Outputs 1 analog output: Hot Water Valve/Actuator (HWV/ACT). AO is 0 to 10VDC (5mA maximum) with 8 bit D/A resolution using filtered PWM.
1 binary output: HEAT1. Relay contact rated at 1A max @ 24VAC/VDC, configured normally open.
Protection Incoming power and network connections are protected by non-replaceable internal solid state polyswitches that reset themselves when the condition that causes a fault returns to normal. The power, network, input and output connections are also protected against voltage transient and surge events.
Battery 10-year lithium CR2032 battery provides a minimum of 10,000 hours of trend data retention during power outages.
Status Indicators LED status indicators for BACnet communication, run status, error, power and all digital outputs
Controller Addressing Rotary DIP switches set BACnet MS/TP or ARCnet address
