Easy Chiller System Logging
The UCM displays data required to log
the chiller system. The following
information is available either as
standard or as an option with the Air-
Cooled Series R
™
Chiller microprocessor:
• Entering and leaving chilled water
temperatures
• Ambient air temperature
• Evaporator and condenser refrigerant
temperatures and pressures
• Compressor suction temperature
• Percent RLA for each compressor
• Percent line voltage
• Compressor starts and running hours
• Active setpoints:
chilled water setpoint
current limit setpoint
ice termination setpoint
low ambient lockout setpoint
• Over 90 diagnostic and operating
conditions
• Part failure diagnostics:
water temperature sensors
refrigerant temperature sensors
compressor contactors
Remote Display Panel
Trane air-cooled Series R
™
70-125 ton
chillers are available with a twisted pair
connection to an optional remote display
panel. Chiller operation can be controlled
similarly to the control interface on the
chiller itself. Through a twisted pair of
wires the unit can be turned on or off,
change the chilled water setpoint, and
display over 90 operating and diagnostic
conditions. The remote display panel can
be mounted indoors so access to chiller
information is just steps away,
eliminating any need to go outdoors or
on the roof.
The clear language display for chiller
sizes of 70-125 tons has the ability to
control multiple units. In a multiple unit
configuration, the Remote Clear
Language Display Panel has the
capability to communicate with up to
four units. Each unit requires a separate
communication link with the Remote
Display Panel.
Easy Interface To The Building
Management System
