The UniTrane fan-coil meets thestandards of todays market, as well asthe anticipated needs of tomorrowsmarket. The tradition that companyfounder Reuben Trane began 60 yearsago continues with the latest generationof fan-coils from The Trane Company.
The UniTrane fan-coil is the leader inthese key areas: Indoor Air Quality (IAQ) Controls Flexibility Quality Serviceability
Todays HVAC market is concerned withissues such as indoor air quality (IAQ) andCFCs that demand a change in HVACproducts. In addition, renovation hasovertaken new construction in the fan-coilmarketdemanding a design that catersto renovation issues. Trane is concernedwith these issues, too. Thats why wedesigned the UniTrane fan-coil as anintegral part of the companys systemsolutions with standard IAQ-relatedfeatures that fully comply withASHRAE 62.
IAQ Design Closed-cell insulation is standard on all
units to help prevent fiberglass in theairstream.
The main and auxiliary drain pans areconstructed of a noncorrosive engi-neered plastic (ABS and CyColac T).
The main and auxiliary drain pans arepositively sloped in every plane toassure proper drainage and helpmaximize protection from microbialgrowth.
The drain pans are removable forcleaning.
Easy filter access encourages frequentchanging.
The auto-economizer damper optionallows free cooling and ventilation tohelp comply with ASHRAE 62andsave energy and operating costs.
UniTrane fan-coils have a blow-thrudesign. Low vertical units are draw-thru.
Controls All controls are factory-mounted and
tested to minimize field setup.
Controls are wired with a 24 VACtransformer to keep only a singlesource power connection requirementto the unit.
All wall-mounted zone sensors requireonly low voltage control wiring from thedevice to the unit control box. (No linevoltage.)
The Tracer controls family introducesthe latest in control technology with theZN.010, ZN.510, and ZN.520 controllers.
The controller automatically determinesthe units correct operating mode (heat/cool) by utilizing a proportional/integral(PI) control algorithm to maintain thespace temperature at the activesetpoint, allowing total comfort control.
Entering water temperature samplingeliminates the need for inefficientbleedlines to sense automaticchangeover on two-pipe changeoverunits.
The random start-up feature helpsreduce electrical demand peaks byrandomly staggering multiple units atstart-up.
Occupied/unoccupied operation allowsthe controller to utilize unoccupiedtemperature setpoints for energysavings.
Warm-up and cool-down energyfeatures are standard with Tranecontrols.
Continuous fan or fan cycling is availablewith ZN.010 or ZN.510.
Monitor unit operation using TracerSummit building management systemwith ZN.510 or ZN.520.
To customize unit control, Tracer Summitor Rover software will allow fieldmodification of ZN.510 and ZN.520default settings. For ZN.010, use Roverto field modify default settings.
Maximize fan-coil system efficiency withfree cooling economizers and modulat-ing valves on units with ZN.520.
Flexibility Two, three, and four-row coils allow
greater design flexibility in two andfour-pipe systems.
One-row steam or hot water reheatcoils for dehudification on units withZN.520 controls.
Fan motors are available for either highstatic (0.4-inch external static pressure)or free discharge applications.
Piping is factory assembled, mountedand tested. Units are also availablewithout piping. Reheat coil piping isavailable on 2-pipe units with hot waterreheat coils and either a fan speedswitch or Tracer ZN.520.
Factory piping options include intercon-necting piping, control valves, and endvalves. Deluxe piping also has unionsand a strainer.
Control options range from a simple fanspeed switch to a DDC controller thatcan tie into a Tracer Summit buildingautomation system.
An 8-inch (20 cm) extended end pocket isan available option on the piping end ofcabinet style units.
Slope-top vertical cabinet units are alsoavailable for school and dormitoryapplications to prevent items frombeing 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 andleak-tested after mounting on the unit.
All control end devices and movingcomponents (fans and motors) arecomputer-tested after units arecomplete.
Serviceability Filters are easily removable and
changed without removing the frontpanel on vertical cabinet units.
Motors are easy to disconnect from thefan board, allowing easy service.
The main and auxiliary drain pans areeasily removable and wipe clean with awet cloth.
The manual output test function is aninvaluable troubleshooting tool. Bysimply pressing the test button on theTracer ZN.510, ZN.520, or ZN.010;service personnel can manuallyexercise outputs in a pre-definedsequence.
