Remote Display Panel -- Air-Cooled 130 to 400 tons.

Remote Clear Language Display Panel for 70 to 125-ton air-cooled chillers

Superior Control 

Unit Control Module 

Trane’s new Adaptive Control™ microprocessor control system enhances the air-cooled Series R chiller by providing the very latest chiller control technology. 

The Trane air-cooled Series R chillers ranging from 130 to 400 ton sizes offer an easy-to-use operator interface panel that displays all operating and safety codes with over 60 diagnostics included. Adaptive Control microprocessor features shut down the chiller only if absolutely necessary. The unit control module (UCM) anticipates potential problems and initiates corrective actions to prevent nuisance tripouts.

State-of-the-Art Equipment 

The new 70 to 125 air-cooled chillers offer the exclusive Trane Adaptive Control logic with the Clear Language Display (UCM). The Clear Language Display has various functions that allow the operator to read unit information and adjust setpoints. The Clear Language Display panel has 16 keys, the readout screen is a two-line, 40 character liquid crystal with a backlight. The backlight allows the operator to read the display in low-light conditions. 

Unit Control Module Features

Equal Compressor Sequencing 

Trane maximizes both compressor and motor life by equalizing both the number of starts and the operating hours. The UCM will start the compressor with the least number of starts and turn off the compressor with the most operating hours. Conventional "auto" lead-lag control will equalize starts, but running hours will typically be unequal. Equalizing both starts and running hours will provide equal compressor wear. 

Internal "Built-In" Chiller Flow Protection 
The UCM automatically detects a no waterflow condition. An external flow switch is not required, which lowers costs versus typical chillers. Built-in flow protection also eliminates nuisance flow switch problems.
