The Zone Controller II provides zone level control for a variety of pressure-independent VAV and pressure dependent VVT applications. This completely programmable 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.
| 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 |
| Separable Actuator | Brushless DC motor, torque 45 inch-pounds (5Nm), 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 | 4 inputs: Configurable for thermistor or dry contact. Inputs 1 and 2 are also configurable for 0–5 Vdc 10 bit A/D resolution. Binary input pulse frequency 10 pulses per second. Minimum pulse width (on or off time) required for each pulse is 50 msec |
| Outputs |
1 analog output:0 to 10VDC (5mA maximum) with 8 bit D/A resolution using filtered PWM 3 binary outputs: Relay contacts 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 or ARCnet 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 |
