Tier 3: 1/1/2012 – No Effective End Date Published EER COP Closed loop water-to-air 17.1 3.6 Open loop water-to-air 21.1 4.1 Closed loop water-to-water 16.1 3.1 Open loop water-to-water 20.1 3.5 7 5 SERIES 500R11 SPECIFICATION CATALOG 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)] Comparison of Test Conditions Conversions: Airflow (lps) = cfm x 0.472; WaterFlow (lps) = GPM x 0.0631; ESP (Pascals) = ESP (in wg) x 249; Press Drop (Pascals) = Press Drop (ft hd) x 2990 ARI 320 ISO/AHRI 13256-1 WLHP ARI 325 ISO/AHRI 13256-1 GWHP ARI 330 ISO/AHRI 13256-1 GLHP Cooling Entering Air - DB/WB °F 80/67 80.6/66.2 80/67 80.6/66.2 80/67 80.6/66.2 Entering Water - °F 85 86 50/70 59 77 77 Fluid Flow Rate * ** ** ** ** ** Heating Entering Air - DB/WB °F 70 68 70 68 70 68 Entering Water - °F 70 68 50/70 50 32 32 Fluid Flow Rate * ** ** ** ** ** Note *: Flow rate is set by 10°F rise in standard cooling test Note **: Flow rate is specified by the manufacturer Part load entering water conditions not shown.

On = Single Stage; Off = Dual Capacity SW2-7 Lockout and Alarm Outputs (P2) – selection of a continuous or pulsed output for both the LO and ALM Outputs. On = Continuous; Off = Pulsed SW2-8 Future Use Alarm Jumper Clip Selection From the factory, ALM is connected to 24 VAC via JW2. By cutting JW2, ALM becomes a dry contact connected to ALG. 13 5 SERIES 500R11 SPECIFICATION CATALOG The Aurora ‘Base’ Control System cont. Safety Features The following safety features are provided to protect the compressor, heat exchangers, wiring and other components from damage caused by operation outside of design conditions. 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. Fault Retry – in the fault condition, the control will stage off the outputs and then “try again” to satisfy the thermostat Y input 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 Y input call, then the control will go to Lockout mode. Lockout – when locked out, the blower will operate continuously, and PSC blower motor output will remain on. 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, thermostat inputs “Y1”, “Y2”, and “W” must be removed for at least 3 seconds. To reset lockout conditions with SW2-8 Off, thermostat inputs “Y1”, “Y2”, “W”, and “DH” must be removed for at least 3 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 3 seconds. 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 hard- wired limit switch if an overpressure condition should occur. 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. Loss of Charge – fault is recognized when the Normally Closed Low Pressure Switch, P4-7/8 is open prior to the compressor starting. 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. 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. 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. Standby In standby mode, Y1, Y2, W, DH, and G are not active. Input O may be active. The blower and compressor will be off. Heating Operation Heating, 1st Stage (Y1) - The blower is started immediately and the compressor is energized 10 seconds after the Y1 input is received. Heating, 2nd Stage (Y1, Y2) - The compressor will be staged to full capacity 20 seconds after Y2 input is received. The ECM blower will shift to high speed. Heating, 3rd Stage (Y1, Y2, W) - The hot water pump is de- energized and the first stage of electric heat is energized 10 seconds after the W command is received. If the demand continues the second stage of electric heat will be energized after 5 minutes. Emergency Heat (W Only) - When the unit is matched with an air handler listed in the Air Handler Compatibility table, the thermostat will send the "W" input to the air handler's control board. 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. Cooling, 1st Stage (Y1, O) - The blower is started immediately and the compressor is energized 10 seconds after the Y1 input is received. Cooling, 2nd Stage (Y1, Y2, O) - The compressor will be staged to full capacity 20 seconds after Y2 input is received. The ECM blower will shift to high speed. Blower (G) - The blower will start immediately upon receiving a thermostat G command. If there are no other commands from the thermostat the ECM will run on “G” speed until the G command is removed. Regardless of blower input (G) from the thermostat, the blower will remain on for 30 seconds at the end of each heating, cooling, and emergency heat cycle. 14 5 SERIES 500R11 SPECIFICATION CATALOG The Aurora ‘Base’ Control System cont.

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, ECM setup, and system configuration capabilities to the Aurora family of controls. An AID Tool is recommended, although not required, for ECM airflow settings. The AID Tool simply plugs into the exterior of the cabinet in the AID Tool port. ABC Control Board Layout 15 5 SERIES 500R11 SPECIFICATION CATALOG 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 Water Quality 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.

Units are not designed to operate at the minimum/maximum conditions on a regular basis. The operating limits are dependant 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. 23 5 SERIES 500R11 SPECIFICATION CATALOG Operating Parameters NDZ026 thru NDZ072 (with NAH Series Air Handler) First Stage Operation Cooling -- No Hot Water Generator Entering Water Temp °F Water Flow gpm/Ton NDZ026 thru NDZ064 NDZ072 NDZ026 thru NDZ072 Suction Pressure PSIG Discharge Pressure PSIG Suction Pressure PSIG Discharge Pressure PSIG Superheat Subcooling Water Temp Rise °F Air Temp Drop °F DB 50 1.5 130-150 193-230 130-150 200-245 8-16 7-14 7-20 18-24 3.0 128-153 190-230 125-140 205-240 8-16 3-10 9-14 18-25 70 1.5 130-150 238-282 135-150 240-280 6-16 4-16 9-18 18-25 3.0 130-155 238-262 125-145 245-270 6-18 5-11 5-10 18-24 90 1.5 133-148 308-340 130-155 300-365 7-16 6-18 4-11 19-25 3.0 138-153 303-333 130-165 305-350 7-18 7-14 5-9 17-22 Heating -- No Hot Water Generator Entering Water Temp °F Water Flow gpm/Ton NDZ026 thru NDZ064 NDZ072 NDZ026 thru NDZ072 Suction Pressure PSIG Discharge Pressure PSIG Suction Pressure PSIG Discharge Pressure PSIG Superheat Subcooling Water Temp Drop °F Air Temp Rise °F DB 30 1.5 78-100 275-325 85-105 325-385 6-11 4-16 2-8 20-29 3.0 78-110 285-325 90-120 335-375 6-11 4-16 3-7 20-32 50 1.5 105-120 305-350 100-130 340-400 5-12 4-16 5-12 24-32 3.0 110-125 305-355 110-125 345-395 9-15 2-14 4-9 20-34 70 1.5 140-155 305-355 130-165 370-430 5-12 2-14 8-12 24-39 3.0 145-160 330-360 140-160 375-425 7-17 7-15 4-9 24-39 Second Stage Operation Cooling -- No Hot Water Generator Entering Water Temp °F Water Flow gpm/Ton NDZ026 thru NDZ064 NDZ072 NDZ026 thru NDZ072 Suction Pressure PSIG Discharge Pressure PSIG Suction Pressure PSIG Discharge Pressure PSIG Superheat Subcooling Water Temp Rise °F Air Temp Drop °F DB 50 1.5 120-140 200-245 105-150 210-270 7-17 6-14 7-16 19-26 3.0 115-140 195-290 110-130 215-260 7-15 4-11 8-12 20-24 70 1.5 121-136 265-310 105-150 280-350 9-15 6-18 7-15 19-25 3.0 123-139 265-310 110-140 285-320 10-16 8-16 8-12 18-24 90 1.5 122-140 310-360 115-140 325-385 8-14 6-18 10-16 18-24 3.0 123-139 310-350 120-135 330-355 8-14 7-15 8-12 17-23 Heating -- No Hot Water Generator Entering Water Temp °F Water Flow gpm/Ton NDZ026 thru NDZ064 NDZ072 NDZ026 thru NDZ072 Suction Pressure PSIG Discharge Pressure PSIG Suction Pressure PSIG Discharge Pressure PSIG Superheat Subcooling Water Temp Drop °F Air Temp Rise °F DB 30 1.5 72-89 295-350 70-100 320-370 7-18 10-20 4-13 18-24 3.0 73-87 305-330 75-90 315-365 7-18 10-20 4-16 18-27 50 1.5 100-120 320-365 95-130 375-430 6-14 6-18 4-10 23-34 3.0 105-120 355-365 100-125 370-420 6-14 6-18 4-9 20-37 70 1.5 142-158 360-380 130-165 400-470 6-12 4-15 6-15 28-38 3.0 138-152 365-390 135-160 405-465 7-14 4-15 6-12 24-42 NOTES: Cooling performance based on entering air temperatures of 80°F DB, 67°F WB.
