Trane

18 available units UniTrane units are individual room air conditioners used in office building, apartments, dormitories, schools, motels and hotels. Product Overview The UniTra fan coil is the leader in these key areas: Energy Efficiency Indoor Air Quality (IAQ) Controls Flexibility Quality Serviceab Energy Efficiency The exclusive use of Electronically Commutated Motors (ECM) incorporates the latest technology for optimized energy efficiency, acousticatement, maintenance free and extended motor life. Each ECM: has a built-in microprocessor that allows for programmability, soft ramp-up, better airflow control, and serial communication. lowers operating costs on average of 50 percent (versus a PSC motor). has a reduced FLA option that allows the unit to ship with a nameplate FLA rating much lower than a typical unit. Indoor Air Quality (IAQ) Standard Closed-cell insulation prevents fiberglass in the airstream. Drain pans are non-corrosive, positively sloped, and cleanable to maximize protection from microbial growth. Easy filter access encourages frequent changing. The auto-economizer damper option allows free cooling and ventilation to help comply with ASHRAE 62—and save energy and operating costs. Controls Available control options: Fan speed control (provided when no control package is selected) Customer-supplied terminal interface (CSTI) Symbio ® 400-B controller with optional factory addressed Air-Fi® Wireless Communications Interface All Trane control options: are factory-mounted, configured and tested to minimize field setup and improve reliability. wired with a 24 Vac transformer to keep only a single source power connection requirement to the unit. automatically determine the unit’s correct operating mode (heat/cool) by utilizing a proportional/integral (PI) control algorithm to maintain the space temperature at the active setpoint, allowing for total comfort control. Monitor unit operation using the Tracer® TU building management system with Symbio® 400-B. To customize unit control, the Tracer® TU will allow field modification of Symbio ® 400-B default settings. Flexibility Two, three, and four-row coils allow greater design flexibility in two and four-pipe systems. One-row steam or hot water reheat coils for dehumidification on units with Symbio® 400-B controls. Fan motors are available for either high static, up to 0.5-inch external static pressure, or free discharge applications. Piping is factory assembled, mounted and tested. Units are also available without piping. Reheat coil piping is available on 2-pipe units with hot water reheat coils and either a fan speed switch or Symbio® 400-B. Control options range from a simple fan speed switch to a DDC controller that can tie into a Tracer SC+ or any building automation system. An 8-inch extended end pocket is available on the piping end of cabinet style units. An additional 8-inch extended end pocket is also available on the controls end of the cabinet style units. Slope-top vertical cabinet units are also available for school and dormitory applications to prevent items from being placed on top of the units. Quality Coils and piping packages are air and leak-tested before mounting on the fan coil. Coil piping connections are also air and leak-tested after mounting on the unit. All control end devices and moving components (fans and motors) are computer-tested after units are complete. Serviceability Touch-safe control box. Integrated user interface with real language LED display. Built-in tachometer. Filters are easily removable and changed without removing the front panel on vertical cabinet units. Motors are easy to disconnect from the fan board, allowing easy service. The main and auxiliary drain pans are easily removable and wipe clean with a wet cloth. The manual output test function is an invaluable troubleshooting tool. By simply pressing the test button on the Tracer ZN520 service personnel can manually exercise outputs in a predefined sequence.
