Controls Overview
Controls Operator Interface
Information is tailored to operators, service technicians and owners. When operating a
chiller, there is specific information you need on a dayto- day basis such as setpoints,
limits, diagnostic information, and reports.
When servicing a chiller, you need different information and a lot more of it such as
historic and active diagnostics, configuration settings, and customizable control algo-
rithms, as well as operation settings.
By providing two different tools, one for daily operation and one for periodic service,
appropriate information is readily accessible.
Large display™ Human Interface
For the operator, day-to-day operational information is presented at the panel. data
(English or SI units) are simultaneously displayed on the touch-sensitive screen.
Logically organized groups of information such as chiller modes of operation, active
diagnostics, settings and reports put information conveniently at your fingertips. See
Operator Interface Section for details.
UT™ Chiller
For the service technician or advanced operator all chiller status, machine configu-
ration settings, customizable limits, and up to 60 active or historic diagnostics are
displayed through the UT™ interface. Using UT™ , a technician can interact with an
individual device or a group of devices for advanced troubleshooting. LED lights and
their respective UT™ indicators visually confirm the viability of each device. Any PC
that meets the system requirements may download the service interface software and
Tracer AdaptiView updates. For more information on UT™ visit your local Trane Ser-
vice company, or The Trane Company’s website at www.trane.com.
