Page 10: Features And Benefits
Features and Benefits Design Advantages The horizontal and vertical configura- tios range in capacities from 1/2 to 5 tons. The innovative designs offers superior field flexibility at the jobsite along with service accessibility. GEH 1/2 to 5-Ton Cabinet The GEH cabinet design includes a modular platform that utilizes similar parts and assemblies throughout the product line. - Page 11 GEH/GEV 6 to 20-Ton Cabinet The cabinet design incorporates sturdy (non painted) galvanized metal form maximum durability and corrosive resistive exterior. The equipment offers superior installation flexibility with service accessibility. The cabinet front allows service access for the controls. The new horizontal and vertical design offers four product vari- ations of return-air and supply-air com- binations.
- Page 12 Features and Benefits Hanging Device: 1/2 to 5-ton The hanging bracket resides in the chamfered corner of the horizontal 1/2 to 5 ton equipment. This partially-concealed bracket design eliminates added height, width, or length to the product. The brackets are factory mounted to shorten job installation requirements.
- Page 13 GEV. Fittings for the supply and return are internally threaded. Expansion Valve All Trane water-source systems include an expansion valve flow metering device. This thermal expansion valve (TXV) allows the unit to operate with an entering fluid temperature from 25 F (3.9 C) to 110 F (43 C), and entering air tem- peratures from 40 F (4.4 C) to 90 F (32 C).
- Page 14 Features and Benefits Blower Motor: 1/2 to 5 ton The supply-air (blower) motor is a multi-speed motor with internal ther- mal overload protection. The motor bearings are permanently lubricated and sealed. All motors are factory wired to the option selected. A high, medium, and low speed tap is provided for field cus- tomization on most voltages.
- Page 15 The ranges are 25, 35, 45, 55, and 60-degrees F (-3 .9 , 1.7, 7.2, 12.8 , 15.6 C). Trane factory sets the controller to 55-degrees F prior to shipment. See Figure 17 for boilerless control/electric heat diagram.
- Page 16 Features and Benefits Hot Gas Reheat (option) For space conditioning and climate con- trol, Trane provides an accurate and cost effective dehumidification control through a hot gas reheat option. This option is designed to accommodate unit sizes 012, 036, 060 and 072 through 240.

Page 17: Controls
Our control options provide a broad range of packages from the most cost efficient 24 volt standalone to a complete building automation solution, Trane is the right choice in comfort gratification. The following chart provides a brief overview in the dif- ferent control combinations. - Page 18 Features and Benefits Basic Controls Figure 20: Basic 24-volt control box. Figure 21: BAsic 24-volt safety devices. Figure 22: 24-volt stand-alone system. Basic 24 Volt Controls The basic 24 V electromechanical unit control provides component protection devices for maximum system reliability. Each device is factory mounted, wired and tested.
- Page 19 With a multiple unit installation, the units may be daisy-chained directly to the Trane Tracer loop controller (TLC), pump(s), boiler, and tower for a com- plete networked water-source system. The TLC provides a night setback out- put, and a pump request input for sys- tem optimization.
- Page 20 The 24 volt deluxe design is a micro- processor-based control board conve- niently located in the control box. The board is unique to Trane water-source products and is designed to control the unit as well as provide outputs for unit status and fault detection.
- Page 21 WSHP-PRC003-EN Features and Benefits ZN510 & ZN524 Controls Tracer ZN510 & ZN524 Controls The Tracer ZN510 and ZN524 are direct digital control (DDC) systems specifical- ly designed for single and dual circuited water-source equipment to provide con- trol of the entire unit, as well as outputs for unit status and fault detection.
- Page 22 Features and Benefits ZN510 & ZN524 Controls Direct Digital Controls When the ZN510 or ZN524 controller is linked directly to the Tracer Summit, each Tracer Summit building automa- tion system can connect a maximum of 120 Tracer ZN510 or ZN524 controllers. See Figure 27 for the Tracer ZN524 board.
- Page 23 More ZN524 Controller Functions: When the building owners choice is Trane Tracer controls, the ZN524 con- troller is required when any of the fol- lowing applications are selected on a single and dual circuited equipment. • Waterside Economizer • Hot Gas Reheat (Dehumidification) •...
- Page 24 This sharing of infor- mation is made possibe via a twisted pair of wire and a building automation system or through Trane’s RoverTM service tool . An advantage of installing a ZN510/ZN524 is its capability to work with other LonTalk certified controllers.

Page 25: Application Considerations
Figure 29: Horizontal unit installation 12”/ 305mm Figure 30: Unit duct collar and hanging device installation. WSHP-PRC003-EN Application Considerations Slope: 1/4” (6.5 mm) Hanging the Horizontal The horizontal unit GEH A is a ceiling hung unit. It is usually applied as a totally concealed unit above an acousti- cal ceiling grid. - Page 26 Application Considerations Condensate Traps When designing a condensate trap for the water-source system, it’s important to consider the unit’s draw through design. Under normal conditions, condensate runs down the coil fins and drips into a condensate pan. In situations where no trap is installed, the water level that would be maintained in the trap to create a seal, backflows through the drainline into the unit.
