AHRI/ISO 13256-1 Performance Ratings cont.
The performance standard AHRI/ASHRAE/ISO 13256-1 became effective January 1, 2000 and replaces ARI 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 Btu/h 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 (Btu/h) + (Blower Power Correction (Watts) x 3.412)
• ISO EER Efficiency (W/W) = ISO Cooling Capacity (Btu/h) 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 (Btu/h) - (Blower Power Correction (Watts) x 3.412)
• ISO COP Efficiency (W/W) = ISO Heating Capacity (Btu/h) x 3.412 / [Power Input (Watts) - Blower Power Correction (Watts) +
Pump Power Correction (Watt)]

Advanced Hot Water Generator Control
(Domestic Hot Water Option)
An AID Tool selectable temperature limit and microprocessor
control of the process is featured. This will maximize hot water
generation and prevent undesirable energy use. An alert will occur
when the hot water input temperature is at or above the set point
(130°F default) for 30 continuous seconds. This alert will appear
as an E15 on the AID Tool 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.
Since compressor hot gas temperature is dependent 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.

SYCAMORE SERIES SPECIFICATION CATALOG
The Aurora Advanced VS Control System cont.
VS Drive and Envelope Control
Advanced Communication Ports
The VS drive operates the compressor between 20 and 100%
capacity. The VS drive communicates any out of refrigerant envelope
conditions to the Aurora and will attempt to adjust the compressor
speed to keep within the envelope. These conditions are measured
using the discharge and suction pressure transducers, discharge
temperature, and current sensors of the drive.
Communication ports P6 and P8 will provide future expansion via
dedicated protocols. These are for future use.
Smart Grid/On Peak (SG) Input
The 'Smart Grid/On Peak' input was designed to allow utilities to
utilize simple radio controlled switches to control the On Electric
Peak behavior of the Aston and Sycamore Series Geothermal
Heat Pumps and provide demand reduction. With a closed
contact signal, this input will limit the operation and thus the
power consumption of the unit by disabling the compressor and
electric heat as long as the signal is present. Code 7 will flash on
the Green LED signifying the 'On Peak' mode. On Peak will also
display on communicating thermostats.
IntelliZone2 Zoning Compatibility
(Optional IntelliZone2 Zoning)
A dedicated input to connect and communicate with the
IntelliZone2 (IZ2) zoning system is provided on P7. There is
a dedicated communication port using a proprietary ModBus
protocol. The AXB is standard on variable speed systems. An AXB
can be added to other selected ABC only systems as well. Then
an advanced communicating IntelliZone2 zoning system can be
added to ABC-only systems. Consult the IntelliZone2 literature for
more information.
Home Automation 1 and 2 Inputs
The electronic expansion valve is operated by the EEV board and
is set to maintain optimal superheat setting for maximum efficiency.
All operation parameters are communicated to the VS drive and
the Aurora system.
The Home Automation inputs are simple closed contact inputs that
will trigger an AID Tool and thermostat alert for the homeowner.
These would require optional sensors and or equipment for
connection to the AXB board. With two inputs, two different
sensors can be selected. The selected text will then be displayed
on the AID Tool and communicating thermostats. These events will
NOT alter functionality or operation of the heat pump/accessories
and is for homeowner/service notification only.
Variable Speed Pump
Home Automation 1 - E23 HA1
This input and output are provided to drive and monitor a
variable speed pump. The VS pump output is a PWM signal to
drive the variable speed pump. The minimum and maximum
level are set using the AID Tool. 50% and 100% are the default
settings respectively. The VS data input allows a separate PWM
signal to return from the pump giving fault and performance
information. Fault received from the variable speed pump will be
displayed as E16.
With a closed dry contact signal, this input will cause an alarm
and Alert Code 23 to indicate on the stat or flash on ABC.
The AID Tool will allow configuration of this input between the
following selections:
• No Action
• Home Automation Fault [no lockout info only] - Output from
home automation system
• Security Alarm [no lockout info only] - Output from
home security
• Sump Alarm Fault [no lockout info only] - Switch output
from sump sensor
• Smoke/CO Alarm Fault [no lockout info only] - Switch
output from Smoke/CO sensor
• Dirty Filter Alarm [no lockout info only] - Output from dirty
filter sensor
Electronic Expansion Valve
Modulating Water Valve
This output is provided to drive a modulating water valve. Through
advanced design the 0-10VDC valve can be driven directly from
the VS Pump output. The minimum and maximum level are set in
the same way as the VS pump using the AID Tool. 50% and 100%
are the default settings respectively.
Home Automation 2 – E24 HA2
Loop Pump Slaving
With a closed dry contact signal, this input will cause an alarm
and Alert Code 24 to indicate on the stat or flash on ABC.
The AID Tool will allow configuration of this input between the
following selections:
• No Action
• Home Automation Fault [no lockout info only] - Output
from home automation system
• Security Alarm [no lockout info only] - Output from
home security
• Sump Alarm Fault [no lockout info only] - Switch output
from sump sensor
This input and output are provided so that two units can be slaved
together with a common flow center. When either unit has a call
for loop outputs, both unit’s loop pump relays and variable speed
pumps are energized. The flow center then can simply be wired to
either unit. The output from one unit should be routed to the input
of the other. If daisy chained, up to 16 heat pumps can wired and
slaved together in this fashion.

Dehumidification – Active
Active dehumidification will only activate during cooling operation
and is based upon the humidity setpoint of the thermostat being
at least 5% below the actual relative humidity and being within the
temperature parameters described here. The green status LED
will flash code 2 when active. The unit can operate a maximum
of 2°F below the cooling setpoint. The compressor will ramp
up and airflow will begin at a low level. Airflow is then reduced
periodically until air coil temperature setpoint is reached. If coil
temperature continues to drop, the airflow is increased until air coil
setpoint is maintained. After 20 minutes of operation in the Active
Dehumidification mode, normal cooling operation will resume for
5 minutes. This cycle continues until the dehumidification setpoint
is reached, room temperature is more than 2°F below cooling
setpoint, or more than 1°F above cooling setpoint (normal cooling
takes over). In IntelliZone2 systems, the main zone will remain
open during active dehumidification.
Monitoring Sensor Kits
Energy Monitoring
(Standard on all Sycamore Series units)
The Energy Monitoring Kit includes two current transducers
(blower and electric heat) added to the existing two compressor
sensors so that the complete power usage of the heat pump can
be measured. The AID Tool provides configuration detail for the
type of blower motor and a line voltage calibration procedure
to improve the accuracy. This information can be displayed
on the AID Tool or selected communicating thermostats. The
TPCM32U04GSR will display instantaneous energy use while the
color touchscreen TPCC32U01GSR will, in addition, display a 13
month history in graph form.
Field Hardware Selectable Options
ABC Field Selectable Options via Button (SW1)
Refrigerant Monitoring
Test/Configuration Button (See SW1 Operation Table)
(Standard on all Sycamore Series units)
The optional Refrigerant Monitoring Kit includes two pressure
transducers, and three temperature sensors, heating liquid
line, suction temperature and existing cooling liquid line (FP1).
These sensors allow the measurement of discharge and suction
pressures, suction and liquid line temperatures as well as
superheat and subcooling. This information will only be displayed
on the AID Tool.
Test Mode
The control is placed in the test mode by holding the push button
switch on the ABC SW1 for 2 - 5 seconds. In test mode most of the
control timings will be shortened by a factor of sixteen (16). LED3
(green) will flash at 1 second on and 1 second off. Additionally,
when entering test mode LED1 (red) will flash the last lockout
one time. Test mode will automatically time out after 30 minutes.
Test mode can be exited by pressing and holding the SW1 button
for 2 to 5 seconds or by cycling the power. NOTE: Test mode will
automatically be exited after 30 minutes.
Performance Monitoring
(Optional sensor kit)
The optional Performance Monitoring Kit includes three
temperature sensors, entering and leaving water, leaving air
temperature and a water flow rate sensor. With this kit heat
of extraction and rejection will be calculated. This requires
configuration using the AID Tool for selection of water or antifreeze.
Variable Speed ECM Configuration Mode
The control is placed in the variable speed ECM configuration mode
by holding the push-button switch SW1 for 5 to 10 seconds, the
high, low, and G variable speed ECM speeds can be selected by
following the LED display lights. LED2 (yellow) will fast flash when
entering the variable speed ECM configuration. When setting G
speed LED3 (green) will be continuously lit, for low speed LED1
(red) will be continuously lit, and for high speed both LED3 (green)
and LED1 (red) will be continuously lit. During the variable speed
ECM configuration mode LED2 (yellow) will flash each of the 12
possible blower speeds 3 times. When the desired speed is flashed
press SW1, LED2 will fast flash until SW1 is released. G speed
has now been selected. Next select low speed, and high speed
blower selections following the same process above. After third
selection has been made, the control will exit the variable speed
ECM configuration mode. Aux blower speed will remain at default or
current setting and requires the AID Tool for adjustment.
Special Modes and Applications
Communicating Digital Thermostats
The Aurora VS controls system also requires either the
monochromatic or color touch screen graphic display thermostats
for user interface. These displays not only feature easy to use
graphical interface but display alerts and faults in plain English.
‘SuperBoost’ Cooling Mode
Occasionally there can be a requirement for a short term ‘boost’
of cooling capacity during a large party etc. The Sycamore Series
allows the user to select ‘SuperBoost’ mode on the thermostat
which will allow the Sycamore Series VS to ramp up an extra 30%
of cooling capacity if needed. This extra ‘SuperBoost’ will only be
available for a 24 hr period and then the unit will revert to normal
operation. The short term boost does not affect ground loop sizing
since it is limited in operation. Continuous use of SuperBoost will
result in overheating of the ground loop.

continuous or pulsed output for both the LO and ALM
Outputs. On = Continuous; Off = Pulsed
NOTE: SW2-7 is not applicable to the Sycamore Series
Future Use
Fuse – a 3 amp automotive type plug-in fuse provides protection
against short circuit or overload conditions.
Anti-Short Cycle Protection – 4 minute anti-short cycle protection
for the compressor.
Random Start – 5 to 80 second random start upon power up.
Alarm Jumper Clip Selection
Fault Retry – in the fault condition, the control will stage off the
outputs and then “try again” to satisfy the thermostat VS call.
Once the thermostat input calls are satisfied, the control will
continue on as if no fault occurred. If 3 consecutive faults occur
without satisfying the thermostat VS call, then the control will go to
Lockout mode.
From the factory, ALM is connected to 24 VAC via JW2. By cutting
JW2, ALM becomes a dry contact connected to ALG.
Variable Speed ECM Blower Speeds
The blower speeds can be changed either by using the variable
speed ECM manual configurations mode method or by using the
Aurora AID Tool directly (see Instruction Guide: Aurora Interface
and Diagnostics (AID) Tool topic).
Lockout – when locked out, the blower will operate continuously in
“G” blower speed setting. The Alarm output (ALM) and Lockout output
(L) will be turned on. The fault type identification display LED1 (Red)
shall flash the fault code. To reset lockout conditions with SW2-8 On,
the demand call must be removed for at least 30 seconds. To reset
lockout conditions with SW2-8 Off, the demand call must be removed
for at least 30 seconds. Lockout may also be reset by turning power
off for at least 30 seconds or by enabling the emergency shutdown
input for at least 30 seconds.
CAUTION: Frequent cycling of power to the drive
can damage the drive! Wait at least 5 minutes
between cycles (connecting and disconnecting
power to the drive).
16
SYCAMORE SERIES SPECIFICATION CATALOG
The Aurora Advanced VS Control System cont.
Lockout With Emergency Heat - if the control is locked out in
the heating mode, and a call for emergency heat is received,
the control will operate in the emergency heat mode while the
compressor is locked out. The first emergency heat output will
be energized 10 seconds after the W input is received, and the
blower will shift to high speed. If the control remains locked out,
and the W input is present, additional stage of emergency heat will
stage on after 2 minutes. When the W input is removed, all of the
emergency heat outputs will turn off, and the variable speed ECM
blower will shift to low speed.
Other Lockouts and Alarms
Several other lockouts and alarms are shown in the Status LED1
(LED1, Red) table with the associated codes visible on the
thermostat, ABC Fault LED, and in text in the AID Tool.
Operation Description
Power Up - The unit will not operate until all the inputs and safety
controls are checked for normal conditions. The unit has a 5 to 80
second random start delay at power up. Then the compressor has
a 4 minute anti-short cycle delay after the random start delay.
High Pressure – fault is recognized when the Normally Closed High
Pressure Switch, P4-9/10 opens, no matter how momentarily. The
High Pressure Switch is electrically in series with the Compressor
Contactor and serves as a hardwired limit switch if an overpressure
condition should occur.
Standby - In standby mode the compressor, pump, and blower
motor are not active. The RV may be active. The blower and
compressor will be off.
Heating Operation - The unit will operate based upon demand as
calculated by the room setpoint algorithm. The resulting compressor
speed (1-12) will also select an appropriate blower speed for the
selected compressor speed. Aux Heat will not be available (on
IntelliZone2 Aux Heat is available on compressor speeds 10-12) until
after the 12th compressor speed has been operational and still is not
satisfying the thermostat, then auxiliary electric heat will be activated.
Low Pressure - fault is recognized when the Normally Closed
Low Pressure Switch, P4-7/8 is continuously open for 30 seconds.
Closure of the LPS any time during the 30 second recognition
time restarts the 30 second continuous open requirement. A
continuously open LPS shall not be recognized during the 2 minute
startup bypass time.
Condensate Overflow - fault is recognized when the impedance
between this line and 24 VAC common or chassis ground drops
below 100K ohms for 30 seconds continuously.
Emergency Heat (W) - The blower will be started on G speed,
10 seconds later the first stage of electric heat will be turned on.
5 seconds after the first stage of electric heat is energized the
blower will shift to Aux speed. If the emergency heat demand is
not satisfied after 2 minutes the second electric heat stage will be
energized.
Freeze Detection-Coax - set points shall be either 30°F or 15°F.
When the thermistor temperature drops below the selected set
point, the control shall begin counting down the 30 seconds delay.
If the thermistor value rises above the selected set point, then the
count should reset. The resistance value must remain below the
selected set point for the entire length of the appropriate delay to
be recognized as a fault. This fault will be ignored for the initial 2
minutes of the compressor run time.
Cooling Operation - The unit will operate based upon demand
as calculated by the room setpoint algorithm. The resulting
compressor speed, speeds 1-9, (speeds 10-12 are reserved for
SuperBoost mode only) will also select an appropriate blower
speed. The blower mode will also have the cooling airflow
adjustment applied. 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.
Freeze Detection-Air Coil - Air Coil Freeze Detection will use the
FP2 input to protect against ice formation on the air coil. The FP2
input will operate exactly like FP1 except that the set point is 30
degrees and is not field adjustable.
Blower (G) - The blower will start immediately upon receiving a
thermostat G command. If there are no other commands from the
thermostat the variable speed ECM will run on low speed until the
G command is removed. Regardless of blower input (G) from the
thermostat, the blower will remain on low speed for 30 seconds at
the end of each heating, cooling, and emergency heat cycle.
Loss of Charge – fault is recognized when the Normally Closed Low
Pressure Switch, P4-7/8 is open prior to the compressor starting.
Over/Under Voltage Shutdown - An over/under voltage condition
exists when the control voltage is outside the range of 18 VAC to
30 VAC. If the over/under voltage shutdown lasts for 15 minutes,
the lockout and alarm relay will be energized. Over/under voltage
shutdown is self-resetting in that if the voltage comes back within
range of 18 VAC to 30 VAC for at least 0.5 seconds, then normal
operation is restored.
Emergency Shutdown - Four (4) seconds after a valid ES input,
P2-7 is present, all control outputs will be turned off and remain
off until the emergency shutdown input is no longer present. The
first time that the compressor is started after the control exits
the emergency shutdown mode, there will be an anti-short cycle
delay followed by a random start delay. Input must be tied to
common to activate.

SYCAMORE SERIES SPECIFICATION CATALOG
The Aurora Advanced VS Control System cont.
Continuous Blower Operation - The blower output will be
energized any time the control has a G input present, unless the
control has an emergency shutdown input present. The blower
output will be turned off when G input is removed.
Aurora Advanced VS Control LED Displays
These three LEDs display the status, configuration, and fault
codes for the control. These can also be read in plain English via
the Aurora AID Tool. See the LED tables for further explanation.
Load Shed - The LS input disables all outputs with the exception

Operation Logic
Heating Mode
Variable Speed Loop Pump
When the variable speed controls determine that heating is
needed in the space the blower will be turned on, the compressor
will be ramped to speed 6 and the loop pump will be started. The
compressor will continue to run at speed 6 for 60 seconds for oil
circulation. During the 60 second oil circulation the controls will
calculate what speed the compressor will need to operate at to
maintain the set point in the space. If the compressor is operating
at speed 12 and the unit is unable to maintain set point the controls
will stage on the electric heat. Electric heat will not operate unless
the compressor is already running at speed 12. Every 30 minutes
if the compressor has been operating lower than speed 6, the
controls will increase the compressor to speed 6 for one minute for
oil circulation.
The variable speed controls will operate the variable speed loop pump
similar to the way the ECM blower motor operates. The speed of
the pump will be increased as the compressor speed is increased to
maintain adequate water flow.
Safe Mode
The system has encountered an unsafe operating condition that
prevents automatic speed control, e.g. lost a sensor signal. To
avoid damage to the system, the drive is running the compressor
at a fixed speed of 2400 rpm awaiting the problem to be solved
and eventually returning to normal operation. If the problem
cannot be solved the drive stops and issues an alarm. (See fault/
alarm table.)
Cooling Mode
Derating
When the variable speed controls determine that cooling is
needed in the space the blower will be turned on, the reversing
valve will be enabled, the compressor will be ramped to speed 6,
and the loop pump will be started. The compressor will continue
to run at speed 6 for 60 seconds for oil circulation. During the 60
second oil circulation the controls will calculate what speed the
compressor will need to operate at to maintain the set point in the
space. The compressor will be limited to a maximum of speed 9
for cooling. If additional capacity is needed SuperBoost mode can
be enabled from the thermostat allowing the compressor to run at
speeds higher than 9 for a period of 24 hours. Every 30 minutes
if the compressor has been operating lower than speed 6, the
controls will increase the compressor to speed 6 for one minute
for oil circulation.
The VS compressor utilizes ‘envelope control’ to maintain
performance within operational limits and improve reliability. To
accomplish this, pressure sensors for discharge and suction
pressure as well as hot gas temperature sensing are used to
monitor the conditions in which the compressor operates. The
envelope does vary based upon operating speed (rpm). When
operating out of these limits the control will attempt to improve
the situation by moderating the compressor speed for a larger
envelope. When this occurs it can be observed on the Aurora
control as an ‘E’ code. The control will automatically try to resolve
the situation. If the situation progresses, a fault and lockout will be
generated by the control.
ECM Blower Motor
The variable speed controls will vary the ECM blower output to
maintain optimum air flow at each of the 12 compressor speeds. If
dehumidification mode is selected during the cooling operation the
airflow will be varied to allow for maximum moisture removal.

SYCAMORE SERIES SPECIFICATION CATALOG
Water Quality
In ground water situations where scaling could be heavy or where
biological growth such as iron bacteria will be present, a closed
loop system is recommended. The heat exchanger coils in ground
water systems may, over a period of time, lose heat exchange
capabilities due to a buildup of mineral deposits inside. These
can be cleaned, but only by a qualified service mechanic, as
special solutions and pumping equipment are required. Hot water
generator coils can likewise become scaled and possibly plugged.

In areas with extremely hard water, the owner should be informed
that the heat exchanger may require occasional flushing.
Units with cupronickel heat exchangers are recommended for
open loop applications due to the increased resistance to build-up
and corrosion, along with reduced wear caused by acid cleaning.
Failure to adhere to the guidelines in the water quality table could
result in the loss of warranty.

** VS Compressor speed is given for the factory default cfm settings. When the cfm default settings are changed it will change the relationship to the
compressor speed that is shown in the table. In cooling mode compressor speeds 10-12 are only available when SuperBoost mode is selected at the
thermostat.
* Optional 1 hp ECM
Factory settings are at recommended L , H and Aux positions
“G” may be located anywhere within the airflow table
“L” setting should be located within the boldface cfm range
“H” setting MUST be located within the shaded cfm range
“Aux” setting MUST be equal to or greater than “H” setting
“Aux” setting MUST be equal to or greater than the minimum allowable cfm for the auxiliary heater kit (see auxiliary heat ratings table)
Cfm is controlled within 5% up to the maximum ESP
Max ESP includes allowance for wet coil and standard filter
ECM Speed Setup - These screens allow the technician to select
the G, low, high, and auxiliary heat blower speed for the ECM
blower motor. Change the highlighted item using the ▲ and ▼
buttons. Press the ◙ button to select the speed.
Setting Blower Speed - ECM
The ABC board’s Yellow Config LED will flash the current ECM
blower speed selections for G, low, and high continuously with a
short pause in between. The speeds can also be confirmed with the
AID Tool under the Setup/ECM Setup screen. The Aux will not be
flashed but can be viewed in the AID Tool. The ECM blower motor
speeds can be field adjusted with or without using an AID Tool.

ECM Setup without an AID Tool
The blower speeds for G only, Low (Y1), and High (Y2/Aux) can be
adjusted directly at the Aurora ABC board which utilizes the push
button (SW1) on the ABC board. This procedure is outlined in the
ECM Configuration Mode portion of the Aurora ‘Base’ Control System
section. The Aux cannot be set manually without an AID Tool.

Notes to Performance Data Tables
The following notes apply to all performance data tables:
• Performance ratings are based on 80°F DB/67°F WB EAT for cooling and 70°F DB EAT for heating.
• Three flow rates are shown for each unit. The lowest flow rate shown is used for geothermal open loop/well water systems with a minimum
of 50°F EWT. The middle flow rate shown is the minimum geothermal closed loop flow rate. The highest flow rate shown is optimum for
geothermal closed loop systems and the suggested flow rate for boiler/tower applications.
• The hot water generator numbers are based on a flow rate of 0.4 gpm/ton of rated capacity with an EWT of 90°F.
• Entering water temperatures below 40°F assumes 15% antifreeze solution.
• For non-standard EAT conditions, apply the appropriate Correction Factor tables.
• Interpolation between EWT, gpm, and cfm data is permissible, extrapolation is not.

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.

WARNING: Gray area represents antifreeze concentrations greater than 35% by weight and should be avoided
due to the extreme performance penalty they represent.
Antifreeze Correction Example
Antifreeze solution is Propylene Glycol 20% by weight. Determine the corrected heating and cooling performance at 30°F and 90°F respectively as well as pressure drop at 30°F for Model 036 operating at 100% capacity.
The corrected cooling capacity at 90°F would be: 35,200 MBtu/h x 0.969 = 34,109 MBtu/h
The corrected heating capacity at 30°F would be: 37,400 MBtu/h x 0.913 = 34,146 MBtu/h
The corrected pressure drop at 30°F and 11.5 gpm would be: 7.9 feet of head x 1.270 = 10.03 feet of head
