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
