Operator Interface
The Trane CenTraVac chiller control
panel, UCP2 is easy to use, understand,
to access information, to read, to change
setpoints, to diagnose problems, to
maintain, and to reset after shutdown.
Convenience
•
Enunciation of all information is at the
front panel display (including power,
voltage, amps, purge, pressures,
refrigerant monitoring, and number of
starts data)
•
Messages displayed using clear
language
Readability
•
LCD multi-language display that is
easy to read from a distance anywhere
within a 60 degree angle.
•
LCD backlight so that the display can
be read in a variety of equipment room
lighting.
