5 This integratedsystem provides total building comfortand control. The primary motivation forbuilding owners/managers in makingthe purchasing decision of an HVAC controls system is no longer just savingenergy; it is having the ability toautomate their facilities and theconvenience of interface to The Comfort SystemAt Trane, we think new technology andinnovation should bring you morecapabilities, more flexibility and at thesame time be able to give youequipment and systems that are easierto use, easier to install, commission andservice. The self -contained IntegratedComfort system saves you time andmoney by simplifying system designand system installation.

6 When used withTrane s DDC/VAV boxes (VariTrane ),system balancing almost goes awaybecause each VAV box is commissionedand tested before it leaves the the status information and editingdata from the self -contained units, VAVboxes, lighting and other auxiliaryequipment are available from Tracer forcontrol, monitoring and service supportof your facility. Tracer, a family ofbuilding automation products fromTrane, is designed with robust,application specific software packagesto minimize custom programmingrequirements and enable system setupand control through simple editing ofparameters in the standard applicationssoftware. Should you select anIntegrated Comfort system for yourfacility, the accountability for equipment,automation and controls is Trane s!
