OPN-VVTZC-02
  • California Prop 65

OVERVIEW

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.

FEATURES

FEATURES & BENEFITS

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

  • 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

SPECIFICATIONS

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 45 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.
