Features and Benefits

Easy to Service

Because today’s owners are very cost- conscious when it comes to service and maintenance, theTrane Voyager was designed with direct input from service contractors.This valuable information helped to design a product that would get the serviceman off the job quicker and save the owner money. Voyager does this by offering:

A Simpler Design

The Voyager design uses fewer parts than previous units. Since it is simpler in design, it is easier to diagnose.

Micro

The Micro requires no special tools to run the Voyager unit through its paces. Simply place a jumper betweenTest 1 andTest 2 terminals on the Low Voltage Terminal Board and the unit will walk through its operational steps automatically.

—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 “system on” LED is lit, the Micro is operational.The light indicates that the Micro is functioning properly.

The Micro features expanded diagnostic capabilities when utilized withTrane’s Integrated Comfort™ Systems.

Some Zone Sensor options have central control panel lights which indicate the mode the unit is in and possible diagnostic information (dirty filters for example).

Easy Access LowVoltageTerminal Board

Voyager’s Low VoltageTerminal Board is external to the electrical control cabinet. It is extremely easy to locate and attach the thermostat wire.This is another cost and time-saving installation feature.

Value

Low Ambient Cooling

All Voyager Commercial units have cooling capabilities down to 0 F as standard.

Power Exhaust Option

Provides exhaust of the return air when using an economizer to maintain proper building pressurization. Great for relieving most building overpressurization problems.

Micro Benefits

The Micro in theVoyager units has built- in anti-short-cycle timer, time delay relay and minimum “on” time controls.These controls are functions of the Micro and are factory tested to assure proper operation.

The Micro softens electrical “spikes” by staging on fans, compressors and heaters.

Intelligent Fallback is a benefit to the building occupant. If a component goes astray, the unit will continue to operate at predetermined temperature setpoint.

Intelligent Anticipation is a standard feature of the Micro. It functions constantly as the Micro and zone sensor work together in harmony to provide tighter comfort control than conventional electro-mechanical thermostats.

Horizontal Discharge with Power Exhaust Option
