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 contractors 

Remote Display Panel 

Trane air-cooled Series R^® 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. 

Remote display panels designed for air-cooled chillers of 130-400 ton ranges can control one unit. However the newly designed 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 

Controlling the air-cooled Series R chiller with building management systems is state-of-the-art yet simple. 

Chiller inputs include:

• Chiller enable/disable
• Circuit enable/disable
• Chilled water setpoint 
• Current limit setpoint
• Ice making enable

Chiller outputs include: 

• Compressor running indication
• Alarm indication (CKt 1 /CKt2)
• Maximum capacity 

Trane Chiller Plant Manager/lCS 

The Tracer^® Chiller Plant Manager Building Management System provides building automation and energy management functions through stand-alone control. The Chiller Plant Manager is capable of monitoring and controlling your entire chiller plant system. 

Application software available:

• Time-of-day scheduling
• Duty cycle
• Demand limiting 
• Chiller sequencing
• Process control language 
• Boolean processing
• Zone control
• Reports and logs 
• Custom messages 
• Run time and maintenance 
• Trend log 
• Totalizing 
• PID control loops 

And of course, Trane’s Chiller Plant Manager Panel can be used on a stand-alone basis or tied into a complete building automation system.
