- Page 7 Sub-standard parts are identified and rejected immediately. Every unit receives a 100% unit run test before leaving the production line to make sure it lives up to rigorous Trane requirements. Ease of Installation Contractors look for lower installation (jobsite) costs.
- Page 8 Easy to Service Because today’s owners are very cost- conscious when it comes to service and maintenance, the Trane 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.

Page 10: Application Considerations
The experience of The Trane Company is that a non-modulating exhaust fan selected for 40 to 50 percent of nominal supply cfm can be applied successfully. - Page 11 Actual clearances which appear inadequate should be reviewed with a local Trane sales engineer. When two or more units are to be placed side by side, the distance between the units should be increased to 150 percent of the recommended single unit clearance.

Page 28: Controls
VAV Units Only Sequence of Operation Supply Air Pressure Control Inlet Guide Vane Control Inlet guide vanes are driven by a modulating 2-10 vdc signal from the VAV Module. A pressure transducer measures duct static pressure, and the inlet guide vanes are modulated to maintain the supply air static pressure within an adjustable user-defined range. - Page 29 CV heating algorithm is in control until the Morning Warm-up setpoint is reached. The unit is then returned to VAV cooling mode. The RT-PRC007-EN Controls Morning Warm-up setpoint is set at the unit mounted VAV Setpoint panel or at a remote panel.
