IntelliPak Chiller Unit Control Module (UCM)

Microprocessor Control

The brain of the 20 to 60 ton air-cooled chiller is its Unit Control Module (UCM). The UCM is an innovative, modular microprocessor control design, which coordinates the actions of the chiller in an efficient manner, providing stand- alone operation of the unit.

Access to the unit controls is via a Human Interface (HI) Panel, a standard component of the IntelliPak chiller. This panel provides a high degree of control. Superior monitoring capability and unmatched diagnostic information is provided through a 2 line 40 character per line, English language display. There are no diagnostic “codes” requiring a translation key for interpretation. All system status information and control adjustments can be made from the onboard Human Interface Panel.

Remote Human Interface (RHI) —The optional Remote Human Interface (RHI) performs the same functions as the Human Interface, with the exception of the service mode. The RHI can be used with up to 4 air-cooled chillers from a single panel.

The Integrated Comfort™ System —The Industry’s MostAdvanced Comfort System

The UCM allows the 20 to 60-ton IntelliPak chiller to be part of the factory installed Integrated Comfort System (ICS). ICS joins theTraneTracer building management systems andTrane HVAC equipment by a single twisted wire pair. This allows bidirectional communication between theTracer system and the unit mounted controls. Connected to the chiller’s UCM, this simple pair allows you to control, monitor, and diagnose your building’s comfort system.The UCM is linked to theTracer system and they electronically “talk” to one another.

Since ICS is factory-packaged, there is no need to install separate sensors to monitor your chiller’s operation. All of the control points are on the controller and ready to go when the unit ships.

Simply hookup theTracer system to the IntelliPak chiller with the twisted wire pair.This feature means lower installed cost, less chance for jobsite errors, less design time on the front end of your project, and fewer callbacks.

ICS gives you the most powerful monitoring and diagnostic system available. Monitoring up to 30 individual points, the ICS can detect and correct problems before a comfort level change is even noticed. Advanced monitoring and diagnostics can help building owners to more effectively market their buildings to prospective tenants.

An ICS system is the most advanced comfort system in the industry. Because Trane has more experience with ICS than all other equipment manufacturers combined, you can feel secure knowing that you are dealing with a proven track record in building management. Trane is the only brand that supplies the entire package.
