GSZ/GTZ Series
Indoor Split
GSZ/GTZ Series splits are designed for indoor installations, and are
connected to an indoor air handler via refrigerant lines and control wiring.
G Series units utilize the ozone-safe R-410A refrigerant to meet the most
stringent EPA requirements now and for many years to come. Easily
accessible controls and connections for refrigerant piping and water piping make this unit simple to install in a wide variety
of applications. Heavy gauge metal cabinets are coated with durable polyester powder coat paint for long lasting beauty and
protection. The GSZ/GTZ Series split will provide exceptional performance and comfort for many years. And because there
is no outdoor blower like ordinary air conditioners or heat pumps, the GSZ/GTZ Series is “whisper quiet”.
GSZ/GTZ Series units are performance-certified to AHRI ISO 13256-1 standards, are ETL safety listed, and are
ENERGYSTAR® qualified.
As a leader in the industry, we are dedicated to innovation, quality and customer satisfaction. In fact, every unit built is
exposed to a wide range of quality control procedures throughout the assembly process and is then subjected to a rigorous
battery of computerized run tests to certify that it meets or exceeds performance standards for efficiency and safety, and
will perform flawlessly at startup. As further affirmation of our quality standards, each unit carries our exclusive Quality
Assurance emblem, signed by the final test technician.

AHRI Data cont.
The performance standard AHRI/ASHRAE/ISO 13256-1 became effective January 1, 2000 and replaces AHRI Standards 320, 325, and
330. This new standard has three major categories: Water Loop (comparable to ARI 320), Ground Water (ARI 325), and Ground Loop (ARI
330). Although these standards are similar there are some differences:
Unit of Measure: The Cooling COP
The cooling efficiency is measured in EER (US version measured in Btuh per Watt. The Metric version is measured in a cooling COP
(Watt per Watt) similar to the traditional COP measurement.
Water Conditions Differences
Entering water temperatures have changed to reflect the centigrade temperature scale. For instance the water loop heating test is
performed with 68°F (20°C) water rounded down from the old 70°F (21.1°C).
Air Conditions Differences
Entering air temperatures have also changed (rounded down) to reflect the centigrade temperature scale. For instance the cooling
tests are performed with 80.6°F (27°C) dry bulb and 66.2°F (19°C) wet bulb entering air instead of the traditional 80°F (26.7°C) DB
and 67°F (19.4°C) WB entering air temperatures. 80.6/66.2 data may be converted to 80/67 using the entering air correction table.
This represents a significantly lower relative humidity than the old 80/67 of 50% and will result in lower latent capacities.
Pump Power Correction Calculation
Within each model, only one water flow rate is specified for all three groups and pumping Watts are calculated using the following
formula. This additional power is added onto the existing power consumption.
• Pump power correction = (gpm x 0.0631) x (Press Drop x 2990) / 300
Where ‘gpm’ is waterflow in gpm and ‘Press Drop’ is the pressure drop through the unit heat exchanger at rated water flow in feet of
head.
Blower Power Correction Calculation
Blower power is corrected to zero external static pressure using the following equation. 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 COPs fairly dramatically over ARI 320, 325, and 330
ratings.
• Blower Power Correction = (cfm x 0.472) x (esp x 249) / 300
Where ‘cfm’ is airflow in cfm and ‘esp’ is the external static pressure at rated airflow in inches of water gauge.
ISO Capacity and Efficiency Calculations
The following equations illustrate cooling calculations:
• ISO Cooling Capacity = Cooling Capacity (Btuh) + (Blower Power Correction (Watts) x 3.412)
• ISO EER Efficiency (W/W) = ISO Cooling Capacity (Btuh) x 3.412 / [Power Input (Watts) - Blower Power Correction (Watts) + Pump
Power Correction (Watt)]
The following equations illustrate heating calculations:
• ISO Heating Capacity = Heating Capacity (Btuh) - (Blower Power Correction (Watts) x 3.412)
• ISO COP Efficiency (W/W) = ISO Heating Capacity (Btuh) x 3.412 / [Power Input (Watts) - Blower Power Correction (Watts) + Pump
Power Correction (Watt)]

NOTES:
* The "Charge Amount with GAH Air Handler" column is based on the charge amount for a GAH Air Handler+Compressor Section/Split.
Additional charge will have to be added accordingly for line set length.
After Charge is added adjustments can be made to get appropriate subcooling and superheat.
Additional charge for R-410A is 0.50 oz. per ft. for 3/8 in. and 1.0 oz. per ft. for 1/2 in. tube.
Longer line sets will reduce capacity and efficiency of the system as well as adversely effect system reliability due to poor oil return.

Hot water generator performance based on 0.4 GPM flow per nominal unit ton at 90°F entering hot water temperature.
Performance data does not include water pumping watts and are based upon 15% (by volume) methanol antifreeze solution.
Multiple Flow Rates (for EWT) are shown in the capacity data tables. The lowest flow rate shown is used for geothermal
open loop/well water systems with a minimum 50°F. The second flow rate shown is the minimum geothermal closed loop
flow rate. The third flow rate shown is optimum for geothermal closed loop and the suggested flow rate for boiler tower
applications. Interpolation between EWT, GPM and CFM data is permissible. Extrapolation for heating data down to 25°F
is permissible. Catalog illustrations cover the general appearance of products at time of publication. We reserve the right to
make changes in design and construction at any time without notice.

NOTE: Minimum/maximum limits are only for start-up conditions, and are meant for bringing
the space up to occupancy temperature. Units are not designed to operate at the minimum/
maximum conditions on a regular basis. The operating limits are dependent upon three
primary factors: 1) water temperature, 2) return air temperature, and 3) ambient temperature.
When any of the factors are at the minimum or maximum levels, the other two factors must
be at the normal level for proper and reliable unit operation.

ASTON SERIES INDOOR SPLIT SPECIFICATION CATALOG
Microprocessor Control
Startup
The unit will not operate until all the inputs and safety controls
are checked for normal conditions. At first power-up, a four
minute delay is employed before the compressor is energized.
Component Sequencing Delays
Components are sequenced and delayed for optimum space
conditioning performance.
Accessory Relay
An accessory relay on the control board allows for field connection of solenoid valves, electronic air cleaners, etc. The accessory relay has a normally open output and a normally
closed output.
Short Cycle Protection
The control employs a minimum "off" time of four minutes to provide for short cycle protection of the compressor.
Shutdown Mode
A 24VAC common signal to the “shutdown” input on the control
board puts the unit into shutdown mode. Compressor, hot water
pump and blower operation are suspended.
Safety Controls
The G Series control receives separate signals for a high
pressure switch for safety, a low pressure switch to prevent loss of
charge damage, and a low suction temperature thermistor for low
source water temperature sensing. Upon a continuous 30-second
measurement of the fault (immediate for high pressure), compressor operation is suspended, the appropriate lockout LED begins
flashing. (Refer to the "Fault Retry" section below.)
Testing
The G Series control allows service personnel to shorten most
timing delays for faster diagnostics.
Fault Retry
Hot Water Justification
Since compressor hot gas temperature is dependant on loop
temperature in cooling mode, loop temperatures may be too low
to allow proper heating of water. The control will monitor water and
refrigerant temperatures to determine if conditions are satisfactory
for heating water. The DHW limit status LED on the unit illuminates
when conditions are not favorable for heating water.
Heating Operation
Heat, 1st Stage (Y1)
The blower motor is started immediately, the loop pump is
energized 5 seconds after the “Y1” input is received, and the
compressor is energized on low capacity 10 seconds after the
“Y1” input. The hot water pump is cycled 30 seconds after the
“Y1” input.
Heat, 2nd Stage (Y1,Y2) Single-Speed Units
The hot water pump is de-energized, which directs all heat
to satisfying the thermostat, and the blower changes to high
speed 15 seconds after the “Y2” input (ECM only).
Heat, 2nd Stage (Y1,Y2) Dual Capacity Units
The second stage compressor will be activated 5 seconds
after receiving a “Y2” input as long as the minimum first stage
compressor run time of 1 minute has expired. The ECM blower
changes from medium to high speed 15 seconds after the “Y2”
input.
The Comfort Alert will delay the second stage compressor until 5 seconds after it receives a “Y2” from the board.
Heat, 3rd Stage (Y1,Y2,W) Single-Speed Units
The first stage of resistance heat is energized 10 seconds
after “W” input, and with continuous 3rd stage demand, the
additional stages of resistance heat engage 90 seconds after
the first stage.
Heat, 3rd Stage (Y1,Y2,W) Dual Capacity Units
All faults are retried twice before finally locking the unit out. An
output signal is made available for a fault LED at the thermostat.
The “fault retry” feature is designed to prevent nuisance service
calls.
The hot water pump is de-energized which directs all heat to satisfy the thermostat. The 1st stage of resistance heat is energized 10 seconds after “W” input, and with continuous 3rd
stage demand, the additional stages of resistance heat engage
90 seconds after the first stage.
Diagnostics
Emergency Heat (W only)
The G Series control board allows all inputs and outputs to be displayed on the LEDs for fast and simple control board
diagnosis.
Hot Water High Limit
(Domestic Hot Water Option)
This mode occurs when the hot water input temperature is at or above 130°F for 30 continuous seconds. The DHW limit status LED on the unit illuminates and the hot water pump de-energizes. Hot water pump operations resume on the next compressor cycle or after 15 minutes of continuous compressor operation
during the current thermostat demand cycle.
The blower is started on high speed, and the first stage
of resistance heat is energized 10 seconds after the "W"
input. Continuing demand will engage the additional stages of
resistance heat 90 seconds after the first stage.
Cooling Operation
In all cooling operations, the reversing valve directly tracks the “O” input. Thus, anytime the “O” input is present, the
reversing valve will be energized.
Cool, 1st Stage (Y1,O)
The blower motor and hot water pump are started
immediately, the loop pump(s) is energized 5 seconds after the
35
ASTON SERIES INDOOR SPLIT SPECIFICATION CATALOG
Microprocessor Control cont.
“Y1” input is received. The compressor will be energized (on
low capacity for Dual Capacity units) 10 seconds after the “Y1”
input. The ECM blower will operate at 85% of medium speed if
in dehumidification mode.
Comfort Alert lockouts cannot be reset at the thermostat.
All other lockout modes can be reset at the thermostat after
turning the unit off, then on, which restores normal operation
but keeps the unit lockout LED illuminated. Interruption of
power to the unit will reset a lockout without a waiting period
and clear all lockout LEDs.
Cool, 2nd Stage (Y1, Y2, O) Single Speed Units
The blower changes to high speed (85% of high speed if in
dehumidification mode) 15 seconds after the “Y2” input (ECM
only).
High Pressure
This lockout mode occurs when the normally closed safety
switch is opened momentarily (set at 600 PSI).
Cool, 2nd Stage (Y1, Y2, O) Dual Capacity Units
Low Pressure
The second stage compressor will be activated 5 seconds
after receiving a “Y2” input as long as the minimum first stage
compressor run time of 1 minute has expired. The ECM blower
changes to high speed 15 seconds after the “Y2” input (85%
of high speed if in dehumidification mode). The Comfort Alert
will delay the second stage compressor until 5 seconds after it
receives a “Y2” from the board.
This lockout mode occurs when the normally closed low
pressure switch is opened for 30 continuous seconds (set at 40 PSI).
A low pressure fault may also be indicated when a Comfort Alert
lockout has occurred.
Freeze Detection (Water Flow)
This lockout mode occurs when the freeze detection
thermistor temperature is at or below the selected point (well
30°F or loop 15°F) for 30 continuous seconds.
Blower (G only)
The blower starts and operates on low speed.
Lockout Conditions
During lockout mode, the appropriate unit and thermostat
lockout LEDs will illuminate. The compressor, loop pump, hot
water pump, and accessory outputs are de-energized. The
blower will continue to run on low speed. If the thermostat calls
for heating, emergency heat operation will occur.

ComforTalk
Fault Flash
When using a TA32W02 or TP32W03 thermostat and SW28 is in the pulsing “L” position, FaultFlash will enable a user
to view the thermostat and count the fault indicator flashes to
determine the lockout condition the unit is experiencing.
When using a TP32U03, 04 or 05 thermostat and SW2-8
is in the pulsing “L” position, ComforTalk will enable the user
to view the thermostat and determine the fault. The thermostat
can be configured to show either lockout text or lockout codes.
The LED board on the front of the unit will display all lockouts.
The Low Pressure LED will flash for a low pressure condition
or a Comfort Alert fault. If the low pressure lockout was caused
by Comfort Alert codes 4, 6 or 7, then the Comfort Alert will
be flashing. If no Comfort Alert code is visible, then it is a low
pressure lockout.
The following tables show the codes that will be displayed on the different ComforTalk and FaultFlash thermostats.
