I-VU® UV OPEN OPN-UV PRODUCT INTEGRATED CONTROLLER
Application Features
- Controls modulating hot water/steam valves or up to 3 stages of electric heat to maintain space temperature setpoint
- Controls modulating chilled water valves or a single stage of DX cooling to maintain space temperature setpoint
- Supports 2-pipe changeover or 4-pipe system combinations
- Controls up to 3 fan speeds
- Built-in advanced control routines for zone level demand control ventilation (ASHRAE® 62)
- Optimal start and PID control for maximum occupant comfort
- Automatic fan speed control for matching fan speed to actual cooling or heating requirements, thus allowing the fan to run at the lowest capable setting to maintain room setpoint
System Benefits
- Fully plug-and-play with the Carrier i-Vu Building Automation System
- Supports demand limiting for energy savings
- Compatible with i-Vu Tenant Billing for tracking tenants’ after-hours energy usage
Hardware Features
- Compatible with 40UV (vertical) and 40UH (horizontal) unit ventilators
- Integrates easily into any BAS using the BACnet MS/TP protocol
- On-board hardware clock, remote occupancy input, and support for Carrier communicating and thermistor sensors provide stand-alone operation
- Thermostat linkage allows up to 8 unit ventilators to operate from 1 sensor
- Easy startup and commissioning using Carrier’s i-Vu user interfaces
| BACNet Support | Advanced application controller (B-AAC), as defined in BACNet 135-2001 Annex L |
| Communication Ports | Network Port: EIA-495 port for BACnet MS/TP communications (baud rate is SIP switch selectable) Comm Option port: For connecting a LON Option Card (future) 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 |
| Inputs | 2 binary inputs: Remote Occupancy Contact/Fan Status and Low Limit Thermostat 4 analog inputs: RAT (10k thermistor), SAT (10k thermistor), OAT (10k thermistor) and Changeover Switch (dry contact)/changeover sensor (10k thermistor). AIs have 10 bit A/D resolution. |
| Outputs | 5 binary outputs: High speed fan, Medium Speed Fan (or Stage 3 Electric Heat), Low Speed Fan (or Stage 2 Electric Heat), 2-Pipe Valve/Heating Valve/Electric Heat Stage 1, and Cooling Valve/Electric Heat Stage 1 with 2-Pipe Electric Heat. Relay contacts rated at 1 A max. @ 24VAC/VDC, configured normally open. 3 analog outputs: Mixed Air Damper, Two-Pipe/Heating Valve/F&B Damper, and Cooling Valve. AOs rated at 0-10VDC 5mA max with 8 bit D/A resolution using filtered PWM. |
| Protection | Incoming power and network connections are protected by non-replaceable internal solidstate polyswitches that reset themselves when the condition that causes a fault returns to normal. The power, network, input, and output connections are also protected. |
| Real Time Clock | Battery-backed real time clock keeps track of time in event of power failure against voltage transient and surge events. |
| Battery | 10-year Lithium CR2032 battery provides a minimum of 10,000 hours of trend data & time retention during power outages. |
| Status Indicators | LED status indicators for communications, run status, error, power, and all digital outputs.Controller AddressingRotary DIP switches set BACnet MS/TP MAC address of controller.Listed ByUL-916 (PAZX), cUL-916 (PAZX7), FCC Part 15-Subpart B-Class A, CE EN50082-1997Environmental Operating RangeOperating: 0° to 140°F (-18° to 54°C), 10-90% relative humidity, non-condensing Storage: -24°F to 140°F (-30° to 60°C), 10-90% relative humidity, non-condensingPower Requirements24VAC +/- 10%, 50-60Hz 18VA power consumption 26VDC (25V min, 30V max Single Class 2 source only, 100VA or less |
Integrated Controller for Unit Ventilators Capable of Stand-Alone Operation or Integrated with Carrier’s or any Building Automation System using BACnet®, Modbus® or Lonworks® Protocol
Carrier’s Unit Vent Open controller is an integrated component of a Carrier unit ventilator. The Unit Vent Open controller continuously monitors and regulates unit ventilator operation with reliability and precision. This advanced controller features a sophisticated, factory engineered control program that provides optimum performance and energy efficiency.
For added flexibility, the Unit Vent Open controller is capable of stand-alone operation, or it can be integrated with any Building Automation System utilizing the BACnet protocol.
