LOCAL ACCESS TO THE UPC OPEN CONTROL- LER — The user can use a BACview6 handheld keypad dis- play unit or the Virtual BACview software as a local user inter- face to an Open controller. These items let the user access the controller network information. These are accessory items and do not come with the UPC Open controller.

The BACview6 unit connects to the local access port on the UPC Open controller. See Fig. F. The BACview software must be running on a laptop computer that is connected to the local access port on the UPC Open controller. The laptop will re- quire an additional USB link cable for connection.

See the BACview Installation and User Guide for instruc- tions on connecting and using the BACview6 device.

To order a BACview6 Handheld (BV6H), consult Commer- cial Products i-Vu®Open Control System Master Prices.

CONFIGURING THE UPC OPEN CONTROLLER'S PROPERTIES — The UPC Open device and ComfortLink™ controls must be set to the same CCN Address (Element) num- ber and CCN Bus number. The factory default settings for CCN Element and CCN Bus number are 1 and 0 respectively.

If modifications to the default Element and Bus number are required, both the ComfortLink and UPC Open configurations must be changed.

The following configurations are used to set the CCN Ad- dress and Bus number in the ComfortLink control. These con- figurations can be changed using the scrolling marquee display or accessory Navigator handheld device.

Configuration→CCN→CCN.A (CCN Address) Configuration→CCN→CCN.B (CCN Bus Number)

The following configurations are used to set the CCN Ad- dress and Bus Number in the UPC Open controller. These con- figurations can be changed using the accessory BACview6 dis- play.

19XRV specifications

The Carrier 19XRV is a cutting-edge rooftop chiller designed to provide reliable and efficient cooling solutions for a wide range of applications, including commercial buildings and industrial facilities. This advanced system integrates the latest technologies and innovative features to ensure optimal performance, energy efficiency, and ease of use.

One of the most prominent features of the 19XRV is its advanced inverter-driven compressor technology. This allows the chiller to adjust its capacity seamlessly based on the building's cooling demand. By varying the speed of the compressor, the 19XRV maximizes energy efficiency and minimizes operational costs, especially during partial load conditions. This capability not only enhances comfort but also contributes to reduced energy consumption, making it a sustainable choice for environmentally conscious users.

In addition to the inverter technology, the 19XRV incorporates a microchannel coil design. This design optimizes heat exchange efficiency and reduces the refrigerant charge, which is an essential factor in lowering greenhouse gas emissions. The microchannel coils also allow for more compact dimensions, making installation easier and maximizing rooftop space usage.

Another significant aspect of the Carrier 19XRV is its robust controls system. Equipped with Carrier’s advanced ComfortLink™ controls, this chiller offers precise monitoring and control over its operation. Users can easily integrate the chiller into building management systems for real-time data access and efficiency analytics. This connectivity ensures that operators can make informed decisions to optimize performance continuously.

The 19XRV also includes features aimed at enhancing reliability and durability. Its structural design incorporates corrosion-resistant materials, allowing the unit to withstand harsh environmental conditions. This reliability translates to lower maintenance requirements and extended equipment lifespan, providing excellent value over time.

Moreover, the chiller is designed for quiet operation, making it suitable for applications where low noise levels are essential. Sound-dampening measures ensure that the 19XRV can be utilized in urban environments or near sensitive areas without causing disturbances.

In conclusion, the Carrier 19XRV is a state-of-the-art rooftop chiller that combines efficiency, technology, and durability. Its inverter-driven compressor, microchannel coil design, advanced controls, and robust construction make it an ideal choice for those looking to maintain comfort while minimizing energy usage and environmental impact. Whether for commercial or industrial applications, the 19XRV stands out as a reliable and innovative cooling solution for the modern age.
