Product Integrated Controller

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.

Application Features

Sophisticated factory-engineered and tested algorithms provide reliability and energy efficiency
Pressure dependent space temperature control
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 room sensors, which allow for local setpoint adjustment and local overrides

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	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
