Split System Overview
Unlike typical split systems on the market, Odyssey offers easy servicing, built-in reliability, ease of
installation and outstanding customer service. And because today’s owners are very cost-conscious
when it comes to service and maintenance, the Odyssey Split System was designed with direct input
from service contractors. This valuable information helped to design a product that would get the service
person off the job quicker and save the owner money.

Flexible Applications
Odyssey offers outstanding standard features enhanced by a variety of factory and field installed
options, multiple control options, rigorously tested proven designs and superior product and technical
support. Because of this, Odyssey offers ultimate flexibility. Units are built to order in our standard
“shortest in the industry” ship cycle time. Odyssey is available with single, dual and manifolded
compressor options. Single compressor outdoor units feature a single refrigeration circuitry, lowering job
installation costs by requiring only one set of refrigerant lines.
Equally important, Odyssey offers single refrigerant circuit/capacity unloading models. The unloading
units feature dual manifolded scroll compressors with two stages of capacity modulation and a single
refrigeration circuit. Dual compressor/dual circuit models give true stand-by protection - if one
compressor fails, the second will automatically start-up. Also, the first compressor can be serviced
without shutting down the unit since the refrigerant circuits are independent. Dual compressor models
also save on energy costs. During light load conditions, only one compressor will operate to save
energy.
Factory installed VFD is standard with most units. These 2–Speed and Single Zone VAV (SZVAV)
solutions, combined with condensing units that have multiple compressors, provide increased part load
performance (IEER) when conditions are not at the max design condition. Additionally, some states
have adopted codes that require this type of performance. Odyssey units are built with installation in
mind. With a smaller footprint, the outdoor unit takes up less space and weighs less, making its
installation more efficient and economical. Our indoor air handlers are built to be installed in confined
spaces, fitting through standard doorways and freight elevators.

Rigorous Testing
Our units are rigorously rain tested to ensure water integrity. Actual shipping tests are performed to
determine packaging requirements. Units are test shipped around the country to determine the best
packaging. Factory shake and drop tests are used as part of the package design process to help assure
that the unit arrives at the job site in top condition. Rigging tests include lifting a unit into the air and
letting it drop one foot, assuring that the lifting lugs and rails hold up under stress. A 100% coil leak test
is performed at the factory. The condenser coils are leak tested at 660 psig and evaporators to 450 psig.
All parts are inspected at the point of final assembly. Sub-standard parts are identified and rejected
immediately. Every unit receives a 100% unit run test before leaving the production line to ensure it lives
up to rigorous Trane requirements.

Symbio™ 700 to provide supply fan motor speed modulation. For SZVAV control, the drive will
accelerate or decelerate as required to meet the Zone Cooling demand. In order to maximize energy
savings, the VFD will be held at minimum speed until the load in the zone requires the speed to
increase. The supply fan speed will be reduced to a minimum of 58%1 during ventilation and part load
cooling demands, and 80% during full load cooling demands with the ability to fully modulate. The
commissioning maximum and minimum airflow points can be easily set by programming these
parameters at the display on the Symbio control board.
Standardized Components — Components are placed in the same location on all Odyssey units.
Because of these standardized components throughout the Odyssey line, contractors/owners can stock
fewer parts.
Symbio™ 700 — Standard on Odyssey condensers, the Symbio™ 700 controller provides exceptional
machine control with a focus on system reliability and application flexibility. The Symbio controller
provides direct access to the Symbio Service and Installation mobile application for easy setup and

Application Considerations
Application of this product should be within the cataloged airflow and performance considerations.

Clearance Requirements
The recommended clearances identified with unit dimensions should be maintained to assure adequate
serviceability, maximum capacity and peak operating efficiency. Actual clearances which appear
inadequate should be reviewed with the local representative.

180° Blower Rotation

The 5, 6, 7.5, and 10 ton standard air handler blower section can be rotated 180° to change the
discharge pattern. This modification must be done in the field and requires an additional kit. See unit
installation guide.

Low Ambient Cooling

As manufactured, all Odyssey units have cooling capabilities down to 0°F. At temperatures below 50°F,
some reduction in cooling capacity can be expected. When the optional Low Ambient Accessory kit is
field installed, the full capacity of the unit is available down to 0°F. When using these units with control
systems such as bypass changeover Variable Air Volume, make sure to consider the requirement for a
head pressure control to allow low ambient cooling.

Selection Procedure
Cooling Capacity
1. Calculate the building’s total and sensible cooling loads at design conditions, using standardized
calculation methods.
2. Size the equipment using the gross cooling capacity tables. Match the cooling loads at design
conditions. For example, if the following specifies the building cooling requirements:
Electrical Characteristics: 460/60/3
Summer Design Conditions: Entering Evap Coil—80°F DB/67°F WB , Outdoor Ambient—95°F
Total Cooling Load: 82 MBh
Sensible Cooling Load: 60 MBh
Airflow: 3000 cfm
External Static Pressure: 0.77 inches of water gauge
3. Use to determine that TWA09043A with TWE09043A has a gross cooling capacity of 94.7 and 75.6
sensible capacity at 95°F DB ambient and 3000 cfm with 80°F DB/67° F WB air entering the
evaporator.
4. To find the net cooling capacities, fan motor heat must be subtracted. Determine the total unit static
pressure:
External Static Duct System: 0.77
Standard Filter: 0.10 in.
Supplementary Electric Heat: 0.23 in.
Total Static Pressure: 1.10 in.
Notes:
• The Evaporator Fan Performance Table has included the effect of a 1 in. filter already.
Therefore, the actual Total Static Pressure is 1.10 - 0.10 = 1.00 in. . With 3000 cfm and
1.00 in., Table 37, p. 49 shows 1.97 Bhp (high static drive kit required).
• This formula can be used to calculate Fan Motor Heat:
3.15 X Bhp = MBh
3.15 X 1.97 = 6.2 MBh
Net Total Cooling Capacity = 94.7 MBh - 6.2 MBh = 93.2 MBh
Net Sensible Cooling Capacity = 75.6 MBh - 6.2 MBh = 75.6 MBh

Heating Capacity
1. Calculate the building heating load using the Trane calculation form or any other standard accepted
method.
2. Size the equipment using to match the heating loads at design conditions. For example, if the
following specifies the building heating requirements:
Total Heating Load: 95.0 MBh
Outdoor Ambient (Winter): 17°F DB
Indoor Return Temperature: 70°F DB
Airflow: 2625 cfm
3. indicates the mechanical heating portion of the heat pump will provide 54.3 MBh for the winter
design conditions. Full heat load must be carried by the supplementary heater in the unlikely event
the heat pump malfunctions. From , the 34.88 kW heater at 460V has a capacity of 119,045. From ,
the 34.88 kW heater at 460V indicates the heater model is BAYHTRL435.

 Selection Procedure

Air Delivery
1. The external static pressure drop through the air distribution system is 0.77 inches of water gauge,
use to determine that the static pressure drop through the electric heater is 0.23 inches of water
(0.77 + 0.23 = 1.00 in.).
2. Enter Table 37, p. 49 for TWE09043A at 2625 cfm and 1.00 static pressure. The high static motor at
995 RPM gives the desired airflow.

Notes:
1. Assumes incompressible and adiabatic flow through grille.
2. Throw distance values are based on a terminal velocity of 75 FPM.
3. Throw distance values at other terminal velocities may be established by multiplying throw distances in the table above by throw
factor as follows: for 50 FPM terminal velocity, multiply by 1.50 throw factor; for 100 FPM terminal velocity, multiply by 0.75 throw
factor; for 150 FPM terminal velocity, multiply by 0.50 throw factor.
4. SZVAV/2-Speed VFD available for 6–25 ton only.

Notes:
1. When electric heater accessory is used, single point power entry or dual point power entry is
field optional. Single point power entry option is through electric heater only.
2. *Choose only one of the following; Thermostat, Mechanical Zone Sensor, Programmable
Zone Sensor Panel or BAS Zone Sensor.
3. **

WARNING
Electrical Shock Hazard!
Failure to follow instructions below could result in death or serious injury.
Properly connect the system’s oversized protective earthing (grounding) terminal.

4. Once power wire connections are complete inside the air handler control box, seal the sheet
metal entry points of the control box by using parts (neoprene gasket, grommet, and plug)
shipped along with the air handler unit package.
Important: For the EDC switch to be functional and thereby facilitate reliable unit operation, make the
EDC connections from the indoor to the outdoor control boxes.
