i-Vu® UV Open
Technical Specifications
Features
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
Specifications
| 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 rates 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 Addressing | Rotary DIP switches set BACnet MS/TP MAC address of controller. |
| Listed By | UL-916 (PAZX), cUL-916 (PAZX7), FCC Part 15-Subpart B-Class A, CE EN50082-1997 |
| Environmental Operating Range | Operating: 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-condensing |
| Power Requirements | 24VAC +/- 10%, 50-60Hz 18VA power consumption 26VDC (25V min, 30V max) Single Class 2 source only, 100VA or less |
