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.
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.
VS Drive and Envelope Control
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.
Loop Pump Linking
This input and output are provided so that two units can
be linked 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 be wired and linked
together in this fashion.
IntelliZone2 Zoning Compatibility
(Optional IntelliZone2 Communicating Zoning)
A dedicated input to connect and communicate with the
IntelliZone2 (IZ2) zoning system is provided on P7 on the
AXB control board. There is a dedicated communication port
using a proprietary ModBus protocol. The AXB is standard
on variable speed systems. Consult the IntelliZone2 literature
for more information.
Advanced Communication Ports
AXB Communication ports P6 and P8 will provide future
expansion via dedicated protocols. These are for future use.
Smart Grid/On Peak (SG) Input
Electronic Expansion Valve (EEV)
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 5 and 7 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.
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.

Home Automation 1 and 2 Inputs
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.
Home Automation 1 - E23 HA1
Variable Speed Pump
With a closed dry contact signal, this input will cause an
alarm and Alert Code 23 to indicate on the stat or flash

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.

‘SuperBoost’ Cooling Mode
Occasionally there can be a requirement for a short term
‘boost’ of cooling capacity during a large party etc. The
7 Series allows the user to select ‘SuperBoost’ mode on
the thermostat which will allow the 7 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.
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 1.5°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 1.5°F below
cooling setpoint, or more than 1°F above cooling setpoint
(normal cooling takes over). In IntelliZone2 systems,
active dehumidification is only enabled when system is
operating on compressor speeds 4 or lower. Once active
dehumidification is activated the main zone and any other
active cooling zone will remain open.
Monitoring Sensor Kits
Energy Monitoring
(Standard on all 7 Series units)
The Energy Monitoring Kit includes two current transducers
(blower and electric heat) added to the existing
compressor drive sensor 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 TPCM32U04A will display
instantaneous energy use while the color touchscreen
TPCC32U01 will, in addition, display a 13 month history in
graph form.
Refrigerant Monitoring
(Standard on all 7 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.

Random Start – 5 to 80 second random start upon power up.
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.

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.
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.
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.
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 selfresetting 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.
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).
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.
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.
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.
Loss of Charge – fault is recognized when the Normally
Closed Low Pressure Switch, P4-7/8 is open prior to the
compressor starting.
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.
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.
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
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.
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.
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.
Aurora Interface and Diagnostics (AID) Tool
The Aurora Interface and
Diagnostics (AID) Tool is
a device that is a member
of the Aurora network.
The AID Tool is used to
troubleshoot equipment
which uses the Aurora
control via Modbus RTU
communication. The AID
Tool provides diagnostics,
fault management, variable speed ECM setup, and system
configuration capabilities to the Aurora family of controls.
An AID Tool is recommended, although not required, for
variable speed ECM airflow settings. The AID Tool simply
plugs into the exterior of the cabinet in the AID Tool port.
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.
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.

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.)
Derating
Cooling Mode
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.
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.
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.

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

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 a 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
