Trane RT-DS-10 - Manuals

5 Features and Benefits Micro Controls • For over 10 years Trane has been working with microprocessor controls in the applied equipment markets. These designs have provided the technology that has been applied to the Voyager units. • The Micro provides unit control for heating, cooling and ventilati...

6 Features and Benefits Excellent Part-Load Efficiency • The Scroll compressor’s unique design allows it to be applied in a passive parallel manifolded piping scheme, something that a “recip” just doesn’t do very well.When the unit begins stage back at part load it still has the full area and circui...

7 Features and Benefits Serviceability Today’s owners are more conscious of the cost of service and maintenance. Voyager was designed with input from service contractors. Their information helped us design a unit that would get the serviceman off the job quicker and save the owner money. Here is why...
