Easy startup and commissioning using Carrier’s BACview Handheld Service Tool
System Benefits
Integrated Carrier airside linkage algorithm for plug-and-play integration with the Carrier WSHP System
Fully plug-and-play with the Carrier i-Vu System
Supports demand limiting for maximum energy savings
Compatible with i-Vu Tenant Billing for tracking tenants’ after-hours energy usage
Specifications
| BACNet Support | Advanced application controller (B-AAC), as defined in BACNet 135-2001 Annex L |
| Communication Ports | Network Comm port: EIA-485 port for BACnet MS/TP, Modbus RTU, or N2 communications (protocol and baud rate are DIP switch selectable); Comm Option port: For connecting a LON Option Card; 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 | 4 analog inputs: Dedicated to Relative Humidity, Indoor Air Quality, Supply Air Temperature, and Leaving Condenser Water Temperature. AI’s have 10 bit A/D resolution. 4 binary inputs: Stage 1 Compressor Status, Condensate Overflow, Fire/Smoke Detector, and Fan Status (optional) |
| Outputs | 2 analog outputs: 1 dedicated to Outside Air Damper, and 1 configurable for either Auxiliary Reheat or Waterside Economizer. AO’s have 10 bit D/A resolution. 8 binary outputs: Supply Fan (low, medium, and high), Compressor Stage 1, Compressor Stage 2, Reversing Valve, Auxiliary Heat/2-position Waterside Economizer, and Dehumidification. Relay contacts rated at 3A max @ 24VAC, 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. |
| Real Time Clock | Battery-backed real time clock keeps track of time in event of power failure |
| 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, Modbus, or N2 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 14VA power consumption 26VDC (25V min, 30V max) Single Class 2 source only, 100VA or less |
