Residential Products Technical Guide
Copeland – turned theory into practical
reality, using sophisticated, computer-assisted
design and manufacturing methods to achieve
the critical tolerances required. In the years
since, Copeland has become the leader in
scroll compressor applications, with nine scroll
manufacturing facilities on three continents and
millions of units installed worldwide.
Copeland Scroll compressors employ two
identical, concentric scrolls, one inserted
within the other. One scroll remains stationary as the other orbits
around it. This movement draws gas into the compression chamber
and moves it through successively smaller “pockets” formed by the
scroll’s rotation, until it reaches maximum pressure at the center
of the chamber. There, it’s released through a discharge port in the
fi xed scroll. During each orbit, several pockets are compressed
simultaneously, so operation is virtually continuous.
Recently, Copeland produced its 500,000th Scroll compressor with
the environmentally sound refrigerant HFC-410A. Field results have
shown that HFC-410A units with Copeland Scroll compressors offer
nearly 30% lower failure rates versus existing R-22 units. HFC-410A
units can reach the industry’s highest effi ciency levels. HFC-410A
scrolls also offer sound advantages to other compressor technologies,
typically operating several decibels quieter than comparable R-22
models. The result is unsurpassed reliability and virtually silent
operation.
Other New Features
• Powder coated cabinet, taupe metallic.
• Liftout handles for front access panels.
• Corrosion and stain resistant stainless steel drain pan with extra
slope designed in.
• Factory mounted fi lter drier for trouble free reliability.
• Easy access low profi le horizontal control box.
• Double isolated compressor for quiet and vibration
free operation.
•
Foil faced insulation in air handling compartment to allow easy
cleaning and prevent microfi ber introduction into the air stream.
• Open Service-Friendly Cabinet ( i.e, all components in
compressor section can be serviced from the front).
Puron® Refrigerant
Puron® is a non-chlorine based (HFC-410A) refrigerant, that with
R-407C and R-134A, is seen as the future of all refrigerants used
worldwide. HFC-410A characteristics compared to R-22 are:
• Binary and near azeotropic mixture of 50% R-32 and
50% R-125.
• Higher effi ciencies (50-60% higher operating pressures)
•
Zero ozone depletion potential and low global warming potential.
• Virtually no glide. Unlike other alternative refrigerants, the
two components in HFC-410A have virtually the same leak
rates. Therefore, refrigerant can be added if necessary without
recovering the charge.
MERV 11 2” Pleated fi lter
All GT-PG units include a factory
installed 2” fi lter rack/duct collar
with a 2” pleated high effi ciency
MERV 11 air fi lter. The MERV
(minimum effi ciency reporting value
per ASHRAE Standard 52.2) design
features ultra low velocity (<300
fpm) for extended fi lter life, low pressure drop (0.13 – 0.18 in. wg.)
and high particulate effi ciency (size E1=41%, E2=69% and E3=87%).
The pleated design and low velocity combine to allow the fi lter to
store a large amount of dirt and result in a practical replacement life of
up to 6 months.
Tin-Coated Air Coil
All Bryant Geothermal GT-
PG Series models feature a
tin-coated air-coil. This coating
process will provide years of
protection against corrosion
from airborne chemicals
resulting from modern building
material out gassing and most
environmental chemicals found
in the air. Modern building
materials such as counter-tops,
fl oor coverings, paints and other materials can “outgas” chemicals into
the home’s air. Some of these chemicals are suspected of contributing
to corrosion in the air coils found in both traditional and geothermal
heating and cooling equipment. Corrosion often results in refrigerant
leaks and eventual failure of the air coil costing hundreds of dollars to
replace. Studies have also shown that these air coil coatings improve
moisture shedding and therefore improve a unit’s moisture removal
capability resulting in a more comfortable home. The GT-PG Series is
your assurance of both maximum air coil life and comfort.
Copeland Scroll Compressor
There’s a reason 9 out of every 10 scroll compressors installed
are Copeland. With over 15 years of painstaking R & D and rigid
production controls, Copeland is able to build the most reliable,
effi cient and quiet scroll compressors in the world.
The concept of compressing a gas by turning one involute form – or
“scroll” – against another around a common axis is nearly a century
old. It wasn’t until the late 1980s, however that one company –

About AHRI/ISO/ASHRAE 13256-1
About AHRI/ISO/ASHRAE 13256-1
AHRI/ASHRAE/ISO 13256-1 (Air-Conditioning and Refrigeration Institute/American Society of Heating, Refrigerating and Air Conditioning
Engineers/International Standards Organization) is a certifi cation standard for water-source heat pumps used in the following applications:
• WLHP (Water Loop Heat Pump – Boiler/Tower)
• GWHP (Ground Water Heat Pump – Open Loop)
• GLHP (Ground Loop Heat Pump – Geothermal)
The directory at http://www.ahrinet.org/ is constantly being updated and immediately available on the Internet. All ratings are submitted by the
manufacturer for certifi cation, and must be approved by AHRI. Therefore, there is a signifi cant difference between AHRI “certifi ed” and AHRI
“rated.” Thirty percent of a manufacturer’s basic models must be tested each year. AHRI selects models at random from stock for testing on
the basis of its evaluation of a participant’s certifi cation data.
Units that fail one or more certifi ed test (90% of declared performance or lower) may be declared defective. If the initial failure is a
performance test, the manufacturer must obsolete all units within the same basic model group or elect to have a second sample tested. If the
second unit fails a performance test, it must be obsoleted, together with all units within the same basic model group. Bryant Geothermal takes
certifi cation seriously. We were recently awarded a certifi cate for consecutive years of no AHRI failures.
Temperatures used in AHRI certifi cation standards are S.I. (Système International – metric) based. For example, typical catalog data for cooling
is shown at 80°F DB/67°F WB [26.7°C DB/19.4°C] entering air temperature, but the AHRI standard for cooling is 80.6°F DB/66.2°F WB
[27°C DB/19°C], since it is based upon whole numbers in degrees Celsius. Water and air temperatures for the standard are shown below.
Data certifi ed by AHRI include heating/cooling capacities, EER (Energy Effi ciency Ratio – Btuh per Watt) and COP (Btuh per Btuh) at the
various conditions shown above. Pump power correction is calculated to adjust effi ciencies for pumping Watts. Within each model, only one
water fl ow rate is specifi ed for all three groups, and pumping Watts are calculated using the formula below. This additional power is added
onto the existing power consumption.
• Pump power correction = (gpm x 0.0631) x (Press Drop x 2990)/300
Fan power is corrected to zero external static pressure using the equation below. The nominal airfl ow is rated at a specifi c external static
pressure. This effectively reduces the power consumption of the unit and increases cooling capacity but decreases heating capacity.
• Fan Power Correction = (cfm x 0.472) x (esp x 249)/300
Capacities and effi ciencies are calculated using the following equations:
• ISO Cooling Capacity = Cooling Capacity (Btuh) + [Fan Power Correction (Watts) x 3.412]
• ISO EER Effi ciency (Btuh/W) =
ISO Cooling Capacity (Btuh)/[Power Input (Watts) – Fan Power Correction (Watts) + Pump Power Correction (Watts)]
• ISO Heating Capacity = Heating Capacity (Btuh) – [Fan Power Correction (Watts) x 3.412]
• ISO COP Effi ciency (Btuh/Btuh) =
ISO Heating Capacity (Btuh) x 3.412/[Power Input (Watts) - Fan Power Correction (Watts) + Pump Power Correction (Watts)]

Performance Data Selection Notes
For operation in the shaded area when water is used in
lieu of an anti-freeze solution, the LWT (Leaving Water
Temperature) must be calculated. Flow must be maintained
to a level such that the LWT is maintained above 40°F
[4.4°C] when the JW3 jumper is not clipped (see example
below). Otherwise, appropriate levels of a proper anti-freeze
should be used in systems with leaving water temperatures
of 40°F or below and the JW3 jumper should be clipped.
This is due to the potential of the refrigerant temperature
being as low as 32°F [0°C] with 40°F [4.4°C] LWT, which may
lead to a nuisance cutout due to the activation of the Low
Temperature Protection. JW3 should never be clipped for
standard range equipment or systems without antifreeze.
Example:
At 50°F EWT (Entering Water Temperature) and 1.5 gpm/
ton, a 3 ton unit has a HE of 22,500 Btuh. To calculate LWT,
rearrange the formula for HE as follows:
HE = TD x GPM x 500, where HE = Heat of Extraction (Btuh);
TD = temperature difference (EWT - LWT) and GPM = U.S.
Gallons per Minute.
TD = HE/(GPM x 500)
TD = 22,500/(4.5 x 500)
TD = 10°F
LWT = EWT - TD
LWT = 50 - 10 = 40°F
In this example, as long as the EWT does not fall below 50°F, the system will operate as designed. For EWTs below 50°F,
higher fl ow rates will be required (open loop systems, for example, require at least 2 gpm/ton when EWT is below 50°F).

GT-PG ECM Control Features
The ECM fan is controlled by an interface board that
converts thermostat inputs and fi eld selectable CFM
settings to signals used by the ECM motor controller.
Units manufactured before July 2005 have version I (P/N
69243707). Units manufactured between July 2005 and
May 11, 2009 have version II (P/N 17B0019N01). Fan
speeds are selected with jumpers for version I or via a
nine position DIP switch for version II and III. To take
full advantage of the ECM motor features, a multi-stage
thermostat should be used (2-stage heat/2-stage cool or
3-stage heat/2-stage cool).
HFC-410A packaged units built after May 11, 2009 have
a ECM controllers version III (P/N 17B0034N01). This
controller includes logic and a relay to control the HWG
functions.
Note: Power must be off to the unit for at least three
seconds before the ECM motor will recognize a speed
change. The motor will recognize a change in the CFM
Adjust or dehumidifi cation mode settings while the unit
is powered.
There are four different airfl ow settings from lowest airfl ow
rate (speed tap 1) to the highest airfl ow rate (speed tap 4).
The charts below indicate settings for both versions of the
ECM interface board, followed by detailed information for
each setting.
Cooling Settings: The cooling setting determines the
cooling (normal) CFM for all units with ECM motor.
Cooling (normal) setting is used when the unit is not in
dehumidifi cation mode. This setting also determines the
heating CFM for GT-G (50YC) units. Tap 1 is the lowest CFM
setting, while tap 4 is the highest CFM setting. To avoid air
coil freeze-up, tap 1 may not be used if the dehumidifi cation
mode is selected. Consult submittal data or specifi cations
catalog for the specifi c unit series and model to correlate
speed tap setting to airfl ow in CFM.
H
eating Settings
: The heating setting determines the
heating CFM for GT-PX (50YD) and GT-PG
(50YE) units.
This setting is not used for
GT-G (50YC)
units. Tap 1 is
the lowest CFM setting, while tap 4 is the highest CFM
setting. Consult submittal data or specifi cations catalog for
the specifi c unit series and model to correlate speed tap
setting to airfl ow in CFM.
Auxiliary/Emergency Heat Settings: The auxiliary/
emergency heat setting determines the CFM when the unit
is in auxiliary heat or emergency heat mode. This setting
is used for residential units with internal electric heat.
When auxiliary electric heat is energized (i.e. compressor
and electric heat), the greater of the auxiliary/emergency
or heating setting will be used. A “G” (fan) signal must be
present from the thermostat for electric heat to operate.
Consult the submittal data or specifi cations catalog for the
specifi c unit series and model to correlate speed tap setting
to airfl ow in CFM.
CFM Adjust Settings: The CFM adjust setting allows
four selections. The NORM setting is the factory default
position. The + or – settings adjust the airfl ow by +/- 15%.
The +/- settings are used to “fi ne tune” airfl ow adjustments.
The TEST setting runs the ECM motor at 70% torque, which
causes the motor to operate like a standard PSC motor, and
disables the CFM counter.
Dehumidifi cation Mode Settings: The dehumidifi cation
mode setting provides fi eld selection of humidity control.
When operating in the normal mode, the cooling airfl ow
settings are determined by the cooling tap setting above.
When dehumidifi cation is enabled there is a reduction in
airfl ow in cooling to increase the moisture removal of the
heat pump. Consult submittal data or specifi cations catalog
for the specifi c unit series and model to correlate speed
tap to airfl ow in CFM. The dehumidifi cation mode can be
enabled in two ways.
1. Constant Dehumidifi cation Mode: When the
dehumidifi cation mode is selected (via DIP switch or
jumper setting), the ECM motor will operate with a
multiplier applied to the cooling CFM settings (approx.
20-25% lower airfl ow). Any time the unit is running in
the cooling mode, it will operate at the lower airfl ow
to improve latent capacity. The “DEHUM” LED will be
illuminated at all times. Heating airfl ow is not affected.
NOTE: Do not select dehumidifi cation mode if cooling
setting is tap 1.
2. Automatic (Humidistat-controlled) Dehumidifi cation
Mode: When the dehumidifi cation mode is selected
(via DIP switch or jumper setting) AND a humidistat is
connected to terminal DH (version II) or HUM (version
I), the cooling airfl ow will only be reduced when the
humidistat senses that additional dehumidifi cation is
required. The DH (or HUM) terminal is reverse logic.
Therefore, a humidistat (not dehumidistat) is required.
The “DEHUM” LED will be illuminated only when
the humidistat is calling for dehumidifi cation mode.
Heating airfl ow is not affected. NOTE: Do not select
dehumidifi cation mode if cooling setting is tap 1.
