UW Credit Union

Controls streamline management, conserve energy at UW Credit Union branches

Various Locations, WI

Project Objective

UW Credit Union is a growing, federally insured financial institution committed to the financial well-being of their more than 173,000 members. The credit union has 20 locations across the state serving the Madison, Milwaukee, Whitewater, Green Bay, Oshkosh and Stevens Point areas. The facilities staff sought to integrate the heating, ventilation and air conditioning (HVAC) controls at numerous locations in order to maximize occupant comfort and minimize energy usage through total building control. The facilities staff also wanted access to all building controls from the corporate office in Madison. The existing control system featured a combination of Carrier variable volume/variable temperature (VVT®) controls, including earlier 3V® controls and more recently installed BACnet® VVT® controls, so the total control solution needed to combine all of these systems into one.

Project Solution

Over the years, Temperature Systems, Inc. (TSI) has supplied UW Credit Union with numerous Carrier 48 series constant volume rooftop units (RTUs) that provide occupant comfort at the credit union’s branch locations, along with the corresponding VVT control systems to monitor and control the RTUs. To accommodate the facilities staff’s desire to expand their control capabilities beyond HVAC, TSI recommended utilizing the BACnet controls’ ability to interface with other applications. TSI further suggested the Carrier i-Vu® Pro web-based user interface to provide access to controls at many of the credit union’s locations. This enabled the facilities staff to troubleshoot distant equipment directly from their office, reducing calls to the local HVAC contractors who service those locations for the credit union.
