Features and Benefits

Micro Controls

Several years ago,Trane was the first to introduce microprocessor controls into the Light Commercial Market.That design, along with immeasurable experience, has provided the technology forTrane’s second-generation ReliaTel™ microprocessor controls in Odyssey split unit systems — the first in the industry.

ReliaTel™ Micro:

•Provides unit control for heating and cooling, by utilizing input from sensors that measure indoor temperature.

•Improves quality and reliability through the use of time-tested microprocessor controls and logic.

•Prevents the unit from short cycling, considerably improving compressor life.

•Ensures that the compressor will run for a specific amount of time, which allows oil to return for better lubrication, enhancing the reliability of the compressor.

•Reduces the number of components required to operate the unit, thereby reducing possibilities for component failure.

•Eliminates the need for field-installed components with its built-in anti-short- cycle timer, time delay relay and minimum ‘’on’’ time controls.These controls are factory tested to assure proper operation.

•Requires no special tools to run the unit through its paces during testing. Simply place a jumper betweenTest 1 andTest 2 terminals on the LowVoltageTerminal Board and the unit will walk through its operational steps.The unit automatically returns control to the zone sensor after stepping through the test mode a single time, even if the jumper is left on the unit.

•As long as the unit has power and the LED is lit, the Micro is operational.The light indicates that the Micro is functioning properly.

•Features expanded diagnostic capabilities when used withTrane’s Integrated ComfortTM Systems.

•As an energy benefit, softens electrical ‘’spikes’’ by staging on fans, compressors and heaters.

•The Intelligent Fallback or Adaptive Control is a benefit to the building occupant. If a component goes astray, the unit will continue to operate at predetermined temperature set points.

•Intelligent Anticipation is a standard feature of the Micro. Functioning constantly, the Micro and zone sensors work together in harmony, to provide tight comfort control.

Electromechanical Controls

•For the simpler job that does not require a building automation system, or expanded diagnostics capabilities, the unit offers electromechanical controls. This 24-volt control includes the control transformer, contactor pressure lugs for power wiring.
