0 MAKE` <br /> Features and Benefits <br /> Multiple-Zone VAV Control <br /> A multiple-zone VAV(MZVAV)system consists of a packaged rooftop unit that serves several <br /> individually controlled zones. Each zone is equipped with a VAV terminal unit that varies the quantity of <br /> air delivered to maintain the desired temperature in that zone.The rooftop unit controller varies the <br /> speed of the indoor fan to maintain the static pressure in the supply ductwork at a setpoint,ensuring that <br /> all zones receive the necessary quantity of air. In addition,cooling capacity is cycled to maintain the <br /> supply air temperature at the desired setpoint. <br /> For decades,Trane has been an industry leader in rooftop VAV systems. Now, multiple-zone VAV <br /> control is available in the light commercial rooftop platform(6 to 25 tons). <br /> Other Benefits <br /> • Cabinet design ensures water integrity <br /> • Ease of Service, Installation and Maintenance <br /> • Mixed model build enables`fastest in the industry"ship cycle times <br /> • Outstanding Airflow Distribution <br /> • Symbio Controls <br /> Quick Adapt Curbs <br /> Enables easy upgrade of existing VoyagerTm 6 to 25 tons units to PrecedentTM units on replacement <br /> jobs. <br /> Rigorous Testing <br /> All of the PrecedentTm designs were rigorously rain tested at the factory to ensure water integrity. <br /> Actual shipping tests were performed to determine packaging requirements. Units were test shipped <br /> around the country to determine the best packaging design. Factory shake and drop tests were used as <br /> part of the package design process to help assure that the unit arrives at the job site in top condition. <br /> Rigging tests include lifting a unit into the air and letting it drop one foot,assuring that the lifting lugs and <br /> rails hold up under stress. <br /> We perform a 100%coil leak test at the factory.The assembled unit is leak tested to 465 psig. <br /> All parts are inspected at the point of final assembly.Sub-standard parts are identified and rejected <br /> immediately. <br /> Every unit receives a 100%unit run test before leaving the production line to make sure it meets <br /> rigorous requirements. <br /> Single Zone VAV (SZVAV) <br /> SZVAV is fully integrated into the control system. It provides the simplest and fastest commissioning in <br /> the industry through proven factory-installed,wired,and tested system controllers.All control modules, <br /> logic boards and sensors are factory installed and tested to ensure the highest quality and most reliable <br /> system available.This means no special programming of algorithms,or hunting at the jobsite for field <br /> installed sensors, boards,etc.SZVAV is a quick and simple solution for many applications and is <br /> available from your most trusted rooftop VAV system solution provider-Trane. <br /> Building system modeling in energy simulation software such as TRACE is recommended to evaluate <br /> performance improvements for your application. <br /> 14 RT-PRC098B-EN <br />
