Trane RTAD chillers are extremely powerful pieces of hardware for regulating the indoor temperatures of commercial and industrial buildings, boasting outstanding power, reality, and simplicity. Even the best chillers and HVAC systems, though, are only as good as their maintenance. To make it easy to operate and maintain the chiller, Trane includes the UCM-CLD chiller control system.
This adaptive control system consists of eight interlinked modules that can be observed through the operator’s interface, providing a wealth of information on the chiller itself, the refrigerant, and the compressor. Control panels such as this are incredibly useful tools for monitoring your chiller’s performance. If there is a problem with your chiller, going through the control system can help you narrow down which component is behaving in a problematic way.
Operating the Trane Chiller UCM-CLD Adaptive Control System
In the video embedded below, one of our technicians walks through the log of operating conditions on the Adaptive Control panel for a customer’s Trane chiller.
Through the eight groups in the module—four report groups and four setting groups—you can receive reports on every aspect of the chiller’s function. Basic data such as whether the unit is running currently, the temperature of the water entering and leaving the evaporator, the temperature of the water entering and leaving the compressor, and the outdoor air temperature are all right at your fingertips in the chiller report.

In the refrigerant report, you are provided with a wealth of information regarding the temperature and pressure of your chiller’s refrigerant, such as:
- Evaporator and condenser refrigerant pressure
- Saturated evaporator and condenser refrigerant temperature
- Purge operating mode and status
- Purge alarm message
- Purge suction and liquid temperature
- Purge pump out rate
Moving onto the compressor report, the UCM-CLD module provides detailed information on the compressor, oil tank, and inlet guide vanes.
- Differential and discharge oil pressure
- Oil tank temperature and pressure
- The position of the inlet guide vane
- Compressor line currents by % RLA and amps
- Compressor winding temperatures
- Compressor starts
- Compressor running time
- Bearing temperatures
The operator’s interface on your Trane RTAD chiller is easy to operate, but the wealth of information it provides can be difficult to parse without specialized training. It takes a qualified technician trained in your chiller’s service procedures, such as the expert technician in our video, to dive deep under the hood of your chiller hardware and perform maintenance on the system or diagnose failure points. An untrained operator may miss serious issues, cause a problem where there wasn’t one before, or make an existing problem worse.
The importance of making a maintenance plan
Your chiller system is only as good as the people maintaining it and fine tuning it for optimal performance. Preventative maintenance by professionals is the key to keeping your building’s chiller operating at peak performance for as long as possible.
To keep your chiller running smoothly, your best option is to schedule regular maintenance sessions with qualified professionals. A maintenance plan ensures that your machine is getting examined at regular intervals, so that you can catch and head off potential problems with your chiller’s performance before they start.
