Features and Benefits
The primary advantage of Trane’s zoning systems is that they are completely integrated systems with Trane’s unitary equipment. Another benefit is that these systems are so simple to install, operate and service, that contractors and installers can take advantage of the delivered concept versus the applied world of design, engineering, and programming. For more information, refer to the table below which describes and compares the features and benefits of Trane’s newest
