Features and Benefits
Barometric Relief (Option)
The Axiom rooftop line offers an optional barometric relief damper for use in conjunction with the
economizer option.This accessory consists of gravity dampers which open because of increased
pressure. As the building air pressure increases, the pressure in the unit’s return air section also
increases, forcing the dampers open and relieving the conditioned space.
Note: The effectiveness of the barometric relief damper during economizing operation is system
related. Pressure drop of the return-air system should be considered to control building
pressurization.
Clogged Filter/Fan Fail Switches
These sensors allow an Integrated Comfort™ System (ICS) or a zone sensor’s service light to
indicate a dirty filter or a fan that is not working.The high field installation costs of these devices
often eliminate them from consideration. By factory installing these features to the rooftop unit,
these sensors are cost effective and a good investment.
Communication Interface
The direct digital control module may be factory or field installed.This module, when applied with
ReliaTel, easily interfaces withTrane’s Integrated Comfort System
Trane’s micro processing controller provides unit control for heating, cooling and ventilation
utilizing input from sensors that measure outdoor and indoor temperature.
Belt-Drive Motor (Option)
With the easy-adjust idler arm, an option available on 12.5- 25 ton units, the belt and sheaves on
the belt driven units can be quickly adjusted without moving the mounted fan motor.The result is
a major savings in time and money.
Blower Motors
Belt and direct drive motor selections are available in both standard and oversized configurations
to meet a wide airflow range.
Co-axial Water-to-Refrigerant Coil
The internal heat exchanging water coil is a copper or cupro-nickel tube-within-a-tube design.The
inner tube of the coil is deeply fluted to enhance heat transfer, and to minimize fouling and scaling.
Colored and Numbered Wiring
The unit wiring is both numbered and color-coded to save time and money when tracing wires or
diagnosing the unit.
Compressors
The Axiom rooftop contains the best compressor technology available to achieve the highest
possible performance. Our compressor line includes reciprocating and scrolls.
Controls by Trane
Several years ago,Trane was the first to introduce microprocessor controls into the light
commercial market. With this control board, a broad range of applications may be explored.This
range includes setups such as a standalone unit to sensor design, to a complete building control
system provided through an ICS design.
WSHP-PRC021-EN 5
Features and Benefits
Why Trane Controls?
Trane ICS controls are factory tested and commissioned to provide comfort, efficiency, and
reliability, as well as, single-source warranty and service. WithTrane’s integrated controls, the
installed costs are lower because the equipment has turn-key factory controls and every
component has been specifically designed to optimize the units performance. When the Axiom
rooftop withTrane controls arrives to the jobsite, it is completely ready for quick installation and
operation.
MicroControls
The unit microprocessor improves quality and reliability through the use of time-tested
microprocessor controls and logic.
Features for the micro processing controls include:
• Provides heating, cooling, and ventilating by utilizing input from sensors that measure outdoor
and indoor temperature.
• Prevents the unit from short cycling, considerably improving compressor life.
• Ensures that the compressor will run for a specific amount of time, which allows oil to return
for better lubrication, enhancing the reliability of the compressor.
• Reduces the number of components required to operate the unit, thereby reducing possibilities
for component failure.
• Eliminates the need for field-installed components with its built-in anti-short-cycle timer, time
delay relay and minimum "on time" controls.These controls are factory tested to assure proper
operation.
• Requires no special tools to run the rooftop unit through its paces during testing. Simply place
a jumper betweenTest 1 andTest 2 terminals on the low voltage terminal board and the unit
will walk through its operational steps.The unit automatically returns control to the zone sensor
after stepping through the test mode a single time, even if the jumper is left on the unit
• As long as the unit has power and the LED is lit, the microprocessor is operational.The light
indicates that the processor is functioning properly.
• Expanded diagnostic capabilities when teamed withTrane’s Integrated Comfort Systems to
become part of a full building management system throughTracer Summit.
• As an energy benefit, the microprocessor based controls soften electrical spikes by staging on
blower fans, compressors and heaters.
• The intelligent fallback or adaptive control is a benefit to the building occupant. If a component
goes astray, the unit will continue to operate at predetermined temperature set points.
• Functioning constantly, the microprocessor and zone sensors work together in harmony to
provide tight comfort control.
6 WSHP-PRC021-EN
Features and Benefits
Convertible Units (3 - 10 Ton)
The units ship in a downflow configuration, but may be easily converted to a horizontal supply by
simply moving two panels.
Condenser Thermostat
A bi-metal element thermostat is installed standard on the water out as a standard option of each
system. This standard option gives extra protection against water freeze due to extreme outside
low temperatures.
Discharge Line Thermostat
A bi-metal element discharge line thermostats installed as a standard option on the discharge line
of each system. This standard option provides extra protection to the compressors against high
discharge temperatures in case of loss of charge, extremely high ambient and other conditions
which could drive the discharge temperature higher.
Easy Access Panels
Easy access panels reduce the number of possible water entry points. By removing only two
screws, entry to the standardized internal components and wiring is possible.All panels are sealed
to prevent water from entering the duct work.
Foil-Faced Insulation
All panels in the air-side section of the unit contain cleanable, foil-faced insulation. All edges are
either captured or sealed to ensure fibers do not get into the airstream.
Quality and Reliability
All Axiom rooftop designs were rigorously rain tested at the factory to help ensure water integrity
Actual shipping tests were performed to determine packaging requirements. Units were test
shipped around the country to determine the best packaging.
Drain Pans
The unit drain pans are of non-corrosive material.They are dual-sloped, and removable for ease
of cleaning.The drain pans are reversible to allow a drain trap installation on either side of the unit.
Duct Flanges
The units come complete with horizontal duct flanges to save additional time and money to the field
contractor during installation.
Easy Access Low Voltage Terminal Strip
The low voltage terminal strip is external to the electrical control cabinet. It is extremely easy
to locate and attach the thermostat wire.
The wiring of the low voltage connections to the unit and the zone sensors is as simple as
matching 1-1, 2-2, and 3-3, which ultimately makes it easier for the installer to wire.
Hinged Access Doors
The hinged access option permits easy access to the filter, fan/air-to-refrigerant coil, and
compressor/control section.This option reduces the potential roof damage that may occur
from fallen screws or access panels. It also provides additional security to the panel during a
high wind situation.
WSHP-PRC021-EN 7
Features and Benefits
Factory shake and drop tests were 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.
We perform a 100% coil leak test at the factory.The air-to-refrigerant coil is leak tested at 470 psig
and pressure tested to 470 psig.
All parts are inspected at the point of final assembly. Sub-standard parts are identified and rejected
immediately.
With verification of total unit performance, our customers can be assured that each unit shipped
will run properly. All equipment is run tested to meet the industry standards developed by AHRI
to insure that global quality standards are met.
Roof Curb
Only one roof curb (both horizontal and down flow discharge) for the 3 through 5-ton or 6 through
10-ton rooftop line simplifies the roof curb selection. Curb selection for the 12 1/2 through 25-ton
equipment is made through only three roof curb combinations.
Safety Devices
All units are equipped with high and low pressure cutout to prevent compressor damage, and
water coil freezing.
The low pressure switch prevents compressor operation under low charge, excessive loss of
charge situations, and under low temperature operation. The high pressure switch prevents
compressor operation during high or excessive discharge pressures.
The following options round-out the complete line of options.
• 0 to 50% manual or motorized outside air
• Electric Heaters
• Supply and/or return smoke detectors
• Discharge air sensor
• Factory built roof curb
• Wide array of zone sensors and thermostats
Single Point Power
A single electrical connection to the contactor powers the unit when unit contains the electric heat
option.
Standardized Components
Components are placed in the same location on all rooftop units to provide a repetitious look and
feel to installation and maintenance personnel.
Through the Base Condensate
Every unit includes provisions for through-the-base condensate drain connections.This allows the
drain to be connected through the roof curb instead of requiring a separate roof penetration.
Reversing Valve
A system reversing valve (4-way valve) is included with all heat pump units.The valve is piped to
be energized in the cooling mode to allow space heating if valve failure were to occur.
Units with the cooling only option will not receive a reversing valve.
8 WSHP-PRC021-EN
Features and Benefits
Unit Base
For additional water integrity, the unit contains a raised 1 1/8-inch lip around the unit’s down flow
supply and return to prevent water from blowing into the ductwork.
Water Connection
The water-in/water-out connections to the co-axial coil are located in the refrigerant section of the
rooftop.These threaded and accessible connections provide a quick installation to a hose
Thermal Expansion Valve (TXV)
AllTrane water-source rooftops systems include a thermal expansion valve.This valve allows the
unit to operate under a large range of entering fluid temperature from 25° F to 110° F, and entering
air temperatures from 40° F to 90° F.This wide temperature range allows the unit to run without
a water regulating device through precise metering of refrigeration flow to achieve desired heating
or cooling.This precise metering by theTXV increases the efficiency of the unit.
Through the Base Electrical Utility Access
Factory provided through-the-base-openings simplifies wiring and piping. Because these
utility openings frequently minimize the number of roof penetrations, the integrity of roofing
materials is enhanced.
Unit Cabinet
The compact cabinet of the 3 through 10-ton equipment contains rounded corners to take up
less room. All units incorporate a one-piece top design to ensure superior water integrity. All
access panels are tightly sealed to prevent water from entering the duct work.
Unit Mounted Disconnect or Circuit Breaker
Codes require a method of assured unit shutdown for servicing. Field installed disconnects
sometimes interfere with service access. Factory installation of unit disconnects reduce costs,
assure proper mounting, and provide the opportunity to upgrade to unit circuit breaker
protection.
WSHP-PRC021-EN 9
Application Considerations
Flexibility
The rooftop water-source heat pump system is versatile for installation in boiler/cooling tower
applications, as well as ground-source (geothermal) applications.The system design may employ
either a central pumping design, or a distributed pumping design.
A central pumping design involves a single pump design, usually located within a basement or
mechanical room to fulfill pumping requirements for the entire building system. An auxiliary pump
is typically applied to lessen the likelihood of system downtime if the main pump malfunctions.
A distributed pumping system contains a single pump module connected directly to the unit supply
and return.This module is field installed and piped to the unit.This design requires individual
pump modules specifically sized for each water-source heat pump.
Building Automation
As part of a building automation system, the mechanical HVAC system may be optimized to lower
energy consumption. By running only the mechanical devices that are required to support the
building load at a given time of day or night means true savings for the building owner.
Maintenance and serviceability faults through the unit sensing devices are easily defined and cured
with an automated system.
The factory shipped DDC controls means turn-key installation and start-up.
Performance
Application of this product should be within the cataloged airflow and unit performance.TheTrane
Official Product Selection System (TOPSS™) will aid in the selection process for a set of given
conditions. If this program has not been made available, ask a localTrane sales engineer to supply
the desired selections or provide a copy of the program.
Condensate
The rooftop unit contains a draw-thru configuration. A negative pressure condensate trap must be
field provided prior to start-up for the unit to drain properly. See the installation manual for negative
pressure trapping.
Because the units have a reversible sloped condensate drain pan, the unit must be installed level.
Any unit slope must be toward the side of the unit where the condensate drain is located.
Hose Kits
A flexible stainless steel hose kit is used to connect the supply and return lines to the water-inlet/
outlet.
10 WSHP-PRC021-EN
Selection Procedure
Selection Program
All WSHP products should be selected through the Trane Official Product Selection System,
TOPSS™.
If this program has not been made available, ask a localTrane sales engineer to supply the desired
selection or a copy of the program.
Required Fields
The first step in the selection is to determine either:
• Total cooling capacity
• Sensible capacity
• Heating capacity
Note: The maximum allowable water pressure drop and selection ranges can also be identified.
TheTOPSS screen for the product is color coded to help identify field requirements.Fields
shadowed in red identify what is required to run aTOPSS calculation.The selection folder is
divided into five fields to allow ease of input for the selection process.These fields include:
• Fan information
• Cooling input information
• Heating input information
• Hose kit information
• All fields information
New Rating
The performance standard AHRI/ASHRAE/ISO 13256-1 became effective Jan. 1, 2000. It replaces
AHRI standards 320, 325 and 330.This new standard has three major categories which include:
Water Loop (AHRI 320), Ground Water (AHRI 325), and Ground Loop (AHRI 330).
The differences in ISO 13256-1 and the old AHRI ratings include:
• Cooling efficiency measurement is a watt per watt measurement similar to the widely used COP
measurement
• Entering water reflects the centigrade temperature scale at 68º F (20º C)
• Entering air reflects the centigrade temperature scale at 80.6º F (27º C) dry bulb and 66.2º F (19º
C) wet bulb.
• Pump power correction factors are added onto the existing power consumption
• Fan power is corrected to zero external static pressure
The rooftop water-source heat pump performance is rated in accordance to the AHRI/ISO 13256-
1 standard.This new standard has three major categories: Water Loop (AHRI 320), Ground Water
(AHRI 325), Ground Loop (AHRI 330). Although these standards are similar there are some
differences.
The cooling efficiency is measured in EER but includes a Watt-per-Watt unit of measure similar to
the traditional COP measurement.
The entering water temperature has changed to reflect the centigrade temperature scale. For
instance the water loop heating test is performed with 68ºF (20ºC) water instead of 70ºF.The cooling
tests are performed with 80.6ºF (27ºC) dry bulb and 66.2ºF (19ºC) wet bulb entering air instead of
the traditional 80ºF dry bulb, and 67ºF wet bulb entering air temperatures.This data (80.6/66.2) may
be converted to 80/67 by using the entering air correction table.
WSHP-PRC021-EN 11
Selection Procedure
A pump power correction has been added onto the existing power consumption. Within each
model, only one water flow rate is specified for each performance category, and pumping watts are
calculated utilizing the pump power correction formula: (gpm x 0.0631) x press drop x 2990) / 300.
Note: GPM relates to water flow, and press drop relates to the drop through the unit heat
exchanger at rated water flow in feet of head.The fan power is corrected to zero external
static pressure.The nominal airflow is rated at a specific external static pressure.This
effectively reduces the power consumption of the unit, and increases cooling capacity but
decreases heating capacity.These watts are significant enough in most cases to increase
EER and COP over AHRI 320, 325, and 330 ratings.
Cooling Dominated Applications
If humidity levels are moderate to high in a cooling dominated application, the heat pump should
be selected to meet or exceed the calculated sensible load. Also, the unit’s sensible capacity should
be no more than 115% of the total cooling load (sensible + latent), unless the calculated latent load
is less than the latent capacity of the unit.
The sensible-to-total cooling ratio can be adjusted with airflow. If the airflow is lowered, the unit
latent capacity will increase. When less air is pulled across the DX coil, more moisture will
condense from the air.
Heating Dominated Applications
Unit sizing in heating dominated applications is based upon humidity levels for the climate, and
goals for operating cost and installation costs.
If humidity levels are moderate, the heat pump should be selected with the heating capacity equal
to 125% of the cooling load.
If humidity levels are low in the application and low operating cost is important, the heat pump and
ground loop should be sized for 90% to 100% of the heating load.
If humidity levels are low and lower initial cost is important, then the heat pump and ground loop
should be sized for 70% to 85% of the heating load, with the remaining load to be treated with
electric resistance heat.
Installation cost will be reduced in this approach because of the smaller heat pump selection and
less loop materials.
In general, the system will not use enough electric heat to offset the higher installation costs
associated with a fully sized or oversized system.
Finally, a unit sized for the entire heating load in a heating dominated application will be oversized
in cooling. Comfort is reduced from increased room humidity caused by short-run times. Short
cycling will also shorten the life expectancy of the equipment and increase power consumption and
operating cost.
Many rebate incentives require the heat pump and ground loop to be sized for the entire heating
load. Check with you local utility for their requirements.

Performance Data
Operating Pressures in Cooling/Heating
There are many variables (airflow, air temperatures) in an air conditioning system that will affect
operating refrigerant pressures and temperatures.The charts below shows approximate
conditions and is based on air flow at the rated SCFM, entering air at 80.6°F(DB), 66.2°F(WB) in
cooling, 68°F(DB) in heating. (+)Heating data with 35°F EWT is based on the use of an anti-freeze
solution having a freezing point 20°F lower than the minimum expected entering temperature.

Performance Data
Example 1 (Ethylene Glycol):
The antifreeze solution is 20% by volume of Ethylene Glycol. Determine the corrected cooling
capacity and waterside pressure drop for a GERA036 when the EWT is 86°F and the GPM is 9.0.
From the catalog data, the cooling capacity at these conditions with 100% water is 39.6 MBTUH,
and the waterside pressure drop is 11.5 feet of head. At 20% Ethylene Glycol, the correction factor
for cool capacity is 0.9912 and the pressure drop is 1.068.
The corrected cooling capacity (MBTUH) = 36.9 * 0.9912 = 36.58.The corrected water side pressure
drop (Ft. head) = 11.5 * 1.068 = 12.23.
Example 2 (Propylene Glycol):
The antifreeze solution is 30% by volume of Propylene Glycol. Determine the corrected heating
capacity and waterside pressure drop for a GERA048 when the EWT is 45°F and the GPM is 12.0.
From the catalog data, the heating capacity at these conditions with 100% water is 49.1 MBTUH,
and the waterside pressure drop is 11.0 feet of head. At 30% Propylene Glycol, the correction factor
for heat capacity is 0.9603 and the pressure drop is 1.174.
The corrected cooling capacity (MBTUH) = 49.1 * 0.9603 = 47.15.The corrected water side pressure
drop (Ft. head) = 11.0 * 1.174 = 12.91.

System balancing hose kit
For automatic system balancing of a water source heat pump, the Mesurflo® self-balancing hose
kit provides a constant flow rate over the pressure differential rage of 2 to 80 psid. As system
pressure changes (through further addition of heat pumps, for example) each individual flow
control valve will automatically adjust to the new system conditions. In variable water volume
applications, a self-balancing hose kit can provide continuous balancing because of its ability to
automatically adjust to the varying system conditions.
Note: At low differential pressure the flow area required to achieve higher flow can exceed the
flow area available for the respective series.Therefore, the minimum pressure differential
requirement is increased for the higher flow ranges of each series Mesurflo valve.
Thermostat/Sensor Location
Location of thermostat or zone sensor is an important element of effective room control and
comfort.The best location is typically on a wall, remote from HVAC unit’s supply/return-air grille.
Readings at this location assure the desired setpoint is achieved across the space, not just near the
unit. It may be necessary to subdivide the zone to ensure adequate control and comfort is
accomplished. Figure 32 indicates areas where thermostat or zone sensor should not be mounted.
These include:
• Near drafts or dead spots (e.g. behind doors or corners)
• Near hot or cold air ducts
• Near radiant heat (e.g. heat emitted from appliances or the sun)
• Near concealed pipes or chimneys
• On outside walls or other non conditioned surfaces
• In air flows from adjacent zones or other units
