The VVT Zone II controller provides zone level temperature and air quality control for a variety of pressure-dependent VVT applications. This advanced controller features a separable actuator for easy installation onto single duct and parallel fan-powered air terminals. It also features native BACnet communications and plug-and-play connectivity to the Carrier i-Vu Building Automation System.
Product Integrated Controller
| BACnet Support | Conforms to the Advanced Application Controller (B-AAC) Standard Device Profile 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 |
| Separable 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 input:Hot Water Valve (HWV). AO is 0 to 10VDC (5mA maximum) with 8 bit D/A resolution using filtered PWM. 3 binary outputs: HEAT1, HEAT2, and FAN. 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 MS/TP communication, run status, error, power and all digital outputs |
| Controller Addressing | Rotary DIP switches set BACnet MS/TP address of controller. |
| Listed by | UL-916 (PAZX), cUL-916 (PAZX7), FCC Part 15-Subpart B-Class A, CE EN50082-1997, UL94-5VA plenum rated enclosure |
| Environmental Operating Range |
Operating: 32° to 130°F (0° to 54°C) 10 to 90% RH, non-condensing Storage: -24° to 140°F (-30° to 60°C) 10 to 90% RH, non-condensing |
| Power Requirements | 24VAC +/- 10%, 50-60Hz, 14 VA power consumption, 26VDC (25V min, 30V max), single class 2 source only, 100 VA or less |
