Location should have enough space for service personnel to perform maintenance or repair. Provide sufficient room to make water, electrical and duct connection(s). If the unit is located in a confined space, such as a closet, provisions must be made for return air to freely enter the space by means of a louvered door, etc. Any access panel screws that would be difficult to remove after the unit is installed should be removed prior to setting the unit. On horizontal units, allow adequate room below the unit for a condensate drain trap and do not locate the unit above supply piping. Care should be taken when units are located in unconditioned spaces to prevent damage from frozen water lines and excessive heat that could damage electrical components. WARNING: Before performing service or maintenance operations on a system, turn off main power switches to the indoor unit. If applicable, turn off the accessory heater power switch. Electrical shock could cause personal injury. Installing and servicing heating and air conditioning equipment can be hazardous due to system pressure and electrical components. Only trained and qualified service personnel should install, repair or service heating and air conditioning equipment. Untrained personnel can perform the basic maintenance functions of cleaning coils and cleaning and replacing filters. All other operations should be performed by trained service personnel. When working on heating and air conditioning equipment, observe precautions in the literature, tags and labels attached to the unit and other safety precautions that may apply. Installing Vertical Units Prior to setting the unit in place, remove and discard the compressor hold down shipping bolt located at the front of the compressor mounting bracket. Follow all safety codes. Wear safety glasses and work gloves. Use a quenching cloth for brazing operations and have a fire extinguisher available. Vertical units are available in left or right air return configurations. Top flow vertical units should be mounted level on a vibration absorbing pad slightly larger than the base to provide isolation between the unit and the floor. It is not necessary to anchor the unit to the floor (see figure below). Moving and Storage Move units in the normal “up” orientation. Horizontal units may be moved and stored per the information on the packaging. Do not stack more than three units in total height. Vertical units may be stored one upon another to a maximum height of two units. Do not attempt to move units while stacked. When the equipment is received, all items should be carefully checked against the bill of lading to be sure all crates and cartons have been received. Examine units for shipping damage, removing the units from the packaging if necessary. Units in question should also be internally inspected. If any damage is noted, the carrier should make the proper notation on the delivery receipt, acknowledging the damage. Vertical Unit Mounting 2 in.

Use only the bolts provided in the kit to attach hanger brackets. The use of longer bolts could damage internal parts. Installing Horizontal Units Remove and discard the compressor hold down shipping bolt located at the front of the compressor mounting bracket prior to setting the unit in place. Horizontal units are available with side or end discharge. Some applications require the installation of horizontal units on an attic floor. In this case, the unit should be set in a full size secondary drain pan on top of a vibration absorbing pad. The secondary drain pan prevents possible condensate overflow or water leakage damage to the ceiling. The secondary drain pan is usually placed on a plywood base isolated from the ceiling joists by additional layers of vibration absorbing material. NOTE: Left (Right) Return Side Discharge cannot be converted to Left (Right) Return End Discharge or vice versa, without additional custom sheet metal parts. Horizontal units are normally suspended from a ceiling by four (009-060 models) or five (070-072 models) 3/8 in. diameter threaded rods. The rods are usually attached to the unit by hanger bracket kits furnished with each unit. CAUTION: Do not use rods smaller than 3/8 in. diameter since they may not be strong enough to support the unit. The rods must be securely anchored to the ceiling. Lay out the threaded rods per the Hanger Bracket Dimensions table. Assemble the hangers to the unit as shown. Securely tighten the brackets to the unit using the weld nuts located on the underside of the bottom panel. When attaching the hanger rods to the bracket, a double nut is required since vibration could loosen a single nut. To allow filter access, install hanger brackets as illustrated in the Hanger Bracket Locations section.

A flexible connector is recommended for discharge and return air duct connections on metal duct systems. Uninsulated duct should be insulated with a minimum of 1-inch duct insulation. Application of the unit to uninsulated ductwork in an unconditioned space is not recommended as the unit’s performance will be adversely affected. The duct system should be sized to handle the design airflow quietly and efficiently. To maximize sound attenuation of the unit blower, the supply and return plenums should include an internal duct liner of fiberglass or constructed of ductboard for the first few feet. On systems employing a sheet metal duct system, canvas connectors should be used between the unit and the ductwork. If air noise or excessive airflow is a problem, the blower speed can be changed. If the unit is connected to existing ductwork, check the duct system to ensure that it has the capacity to accommodate the air required for the unit application. If the duct is too small, as in the replacement of heating only systems, larger ductwork should be installed. All existing ductwork should be checked for leaks and repaired if necessary. Water Piping All source water connections on commercial units are fittings that accept a male pipe thread (MPT). Insert the connectors by hand, then tighten the fitting with a wrench to provide a leakproof joint. When connecting to an open loop (groundwater) system, thread any copper MPT fitting into the connector and tighten in the same manner as described above. The proper water flow must be provided to each unit whenever the unit operates. To assure proper flow, use pressure/temperature ports to determine the flow rate. These ports should be located at the supply and return water connections on the unit. The proper flow rate cannot be accurately set without measuring the water pressure drop through the refrigerant-to-water heat exchanger. Condensate Drain On vertical units, the internal condensate drain assembly consists of a drain tube which is connected to the drain pan, a 3/4 in. PVC female adapter and a flexible connecting hose. The female adapter may exit either the front or the side of the cabinet. The adapter should be glued to the field-installed PVC condensate piping. On vertical units, a condensate hose is inside all cabinets as a trapping loop; therefore, an external trap is not necessary. On horizontal units, a PVC stub or stainless steel tube is provided for condensate drain piping connection. An external trap is required (see below). If a vent is necessary, an open stand pipe may be applied to a tee in the field-installed condensate piping.

Drain NOTE: Check dimensional data for actual PVC sizes. 12 RG SERIES INSTALLATION MANUAL 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. Material pH Scaling Acidity/Alkalinity Calcium and Magnesium Carbonate Hydrogen Sulfide Corrosion Iron Fouling (Biological Growth) Sulfates Chlorine Chlorides Carbon Dioxide Ammonia Ammonia Chloride Ammonia Nitrate Ammonia Hydroxide Ammonia Sulfate Total Dissolved Solids (TDS) LSI Index Iron, FE2+ (Ferrous) Bacterial Iron Potential Iron Oxide Suspended Solids Erosion Threshold Velocity (Fresh Water) NOTES: Grains = ppm divided by 17 mg/L is equivalent to ppm In areas with extremely hard water, the owner should be informed that the heat exchanger may require occasional flushing. Failure to adhere to the guidelines in the water quality table could result in loss of warranty. 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.

Test the system water for acidity and treat as required to leave the water slightly alkaline (pH 7.5 to 8.5). The specified percentage of antifreeze may also be added at this time. Use commercial grade antifreeze designed for HVAC systems only. Environol™ brand antifreeze is recommended. Cleaning and Flushing Prior to start up of any heat pump, the water circulating system must be cleaned and flushed of all dirt and debris. If the system is equipped with water shutoff valves, the supply and return runouts must be connected together at each unit location (This will prevent the introduction of dirt into the unit, see Flushing with Water Shutoff Valve Equipped Systems illustration). The system should be filled at the water make-up connection with all air vents open. After filling, vents should be closed. Once the system has been filled with clean water and antifreeze (if used), precautions should be taken to protect the system from dirty water conditions. Dirty water will result in system-wide degradation of performance, and solids may clog valves, strainers, flow regulators, etc. Additionally, the heat exchanger may become clogged which reduces compressor service life and can cause premature unit failure. Flushing with Water Shutoff Valve Equipped Systems In boiler/tower application, set the loop control panel set points to desired temperatures. Supply power to all motors and start the circulating pumps. After full flow has been established through all components including the heat rejector (regardless of season), air vented and loop temperatures stabilized, each of the units will be ready for check, test and start up and for air and water balancing. Return Runout Supply Runout Ground Source Loop System Checkout Mains Rubber Hose Once piping is completed between the unit pumping system and ground loop, final purging and charging of the loop is needed. A high pressure pump is needed to achieve adequate flow velocity in the loop to purge air and dirt particles from the loop itself. Antifreeze solution is used in most areas to prevent freezing. Flush the system adequately to remove as much air as possible; then pressurize the loop to a static pressure of 40-50 PSI (summer) or 50-75 PSI (winter). This is normally adequate for good system operation. Loop static pressure may decrease soon after initial installation, due to pipe expansion and loop temperature change. Running the unit for at least 30 minutes after the system has been completely purged of air will allow for the “break-in” period. It may be necessary to adjust static loop pressure (by adding water) after the unit has run for the first time. Loop static pressure will also fluctuate with the seasons. Pressures will be higher in the winter months than during the cooling season. This fluctuation is normal and should be considered when charging the system initially. Runouts Initially Connected Together The contractor should start the main circulator with the pressure reducing valve makeup open. Vents should be checked in sequence to bleed off any trapped air and to verify circulation through all components of the system. As water circulates through the system, the contractor should check and repair any leaks found in the piping system. Drain(s) at the lowest point(s) in the system should be opened for initial flush and blowdown, making sure water fill valves are set at the same rate. Check the pressure gauge at the pump suction and manually adjust the make-up water valve to hold the same positive pressure both before and after opening the drain valves. Flushing should continue for at least two hours, or longer if required, until drain water is clean and clear. Ensure the pump provides adequate flow through the unit by checking pressure drop across the heat exchanger. Usually 2.25-3.0 gpm of flow per ton of cooling capacity is recommended in earth loop applications. The supplemental heater and/or circulator pump, if used, should be shut off. All drains and vents should be opened to completely drain the system. Short-circuited supply and return runouts should now be connected to the unit supply and return connections. 14 RG SERIES INSTALLATION MANUAL Open Loop Ground Water Systems Typical open loop piping is shown below. Always maintain water pressure in the heat exchanger by placing water control valves at the outlet of the unit to prevent mineral precipitation. Use a closed, bladder-type expansion tank to minimize mineral formation due to air exposure. Insure proper water flow through the unit by checking pressure drop across the heat exchanger and comparing it to the figures in unit capacity data tables in the specification catalog. 1.5-2 gpm of flow per ton of cooling capacity is recommended in open loop applications. Due to only minor differences in flow rate from low to high, only one solenoid valve should be used. The valve should be sized for full flow. Discharge water from the unit is not contaminated in any manner and can be disposed of in various ways, depending on local codes, i.e. recharge well, storm sewer, drain field, adjacent stream or pond, etc. Most local codes forbid the use of sanitary sewer for disposal. Consult your local building and zoning departments to assure compliance in your area. Open System - Groundwater Application Unit Supply Aux.

Run interconnecting copper tubing between the unit DHW water “IN” and the tee (1/2-inch nominal). The recommended maximum distance is 50 feet. 11. To prevent air entrapment in the system, install a vent coupling at the highest point of the interconnecting lines. 12. Insulate all exposed surfaces of both connecting water lines with 3/8-inch wall closed cell insulation. NOTE: All plumbing and piping connections must comply with local plumbing codes. 16 RG SERIES INSTALLATION MANUAL Hot Water Generator Connections cont. 10. Make sure that any valves in the hot water generator circuit are open. 11. Turn on the unit to heating. 12. The HWG pump should be running. When the pump is first started, turn the venting (burping) screw (if equipped) in the center of the pump two (2) turns open until water dribbles out, then replace. Allow the pump to run for at least five minutes to ensure that water has filled the circulator properly. 13. The temperature difference between the water entering and leaving the hot water generator should be 5°F to 15°F. The water flow should be approximately 0.4 gpm per ton of nominal cooling. 14. Allow the unit to heat water for 15 to 20 minutes to be sure operation is normal. Hot Water Generator Startup 1. Make sure the power is off to the heat pump. Connect the wire from the hot water generator pump to T1 on the contactor. 2. Close the drain valve to the water heater. 3. Open the cold water supply to the tank. 4. Open a hot water faucet in the building to bleed air from the system. Close when full. 5. Open the pressure relief valve to bleed any remaining air from the tank, then close. 6. If so equipped, turn the venting (burping) screw in the center of the pump two (2) turns open (water will drip out), wait until all air is purged from the pump, then tighten the plug. Use vent couplings to bleed air from the lines. 7. Carefully inspect all plumbing for water leaks and correct as required. 8. Before restoring electrical supply to the water heater, adjust the temperature setting on the tank. • On tanks with both upper and lower elements, the lower element should be turned down to the lowest setting, approximately 100°F. The upper element should be adjusted to 120°F to 130°F. Depending upon the specific needs of the customer, you may want to adjust the upper element differently. • On tanks with a single element, lower the thermostat setting to 120°F. 9. After the thermostat(s) is adjusted, replace the access cover and restore electrical supply to the water heater. CAUTION: Never operate the HWG circulating pump while dry. If the unit is placed in operation before the hot water generator piping is connected, be sure that the pump wires are disconnected from the contactor. 17 RG SERIES INSTALLATION MANUAL Freeze Detection For Aurora Base Control, set SW2-1, FP1, on the printed circuit board for applications using a closed loop antifreeze solution to 15°F [-9.4°C]. On applications using an open loop/ground water system (or closed loop no antifreeze), set this dip switch to 30°F [-1.1°C], the factory default setting. (Refer to the Dip Switch Field Selection table). Electrical Connections General 208 Volt Operation Be sure the available power is the same voltage and phase as that shown on the unit serial plate. Line and low voltage wiring must be done in accordance with local codes or the National Electric Code, whichever is applicable. All RG Series 208/230 units are factory wired for 230 volt operation. For 208 volt operation, the red and blue transformer wires must be switched on terminal strip PS. CAUTION: When installing a unit with an variable speed ECM blower motor in 460/60/3 voltage, a neutral wire is required to allow proper unit operation. Power Connection Connect the incoming line voltage wires to L1 and L2 of the contactor for single-phase unit. Consult the Electrical Data tables for correct fuse sizes.

5-Speed ECM 5-speed ECM blower motors have five (5) speeds of which three (3) are selectable on single speed and four (4) are selectable on dual capacity. CAUTION: Disconnect all power before performing this operation. 24 RG SERIES INSTALLATION MANUAL 5-Speed ECM Contant Torque Motors Signal Connection - 1/4 in. quick connects - Common to C, 24VAC to Taps #1-5. The 5-speed ECM is a ‘Constant Torque’ ECM motor and delivers air flow similar to a PSC but operates as efficiently as an variable speed ECM motor. Because it’s an ECM Motor, the 5-speed ECM can ramp slowly up or down like the variable speed ECM motor. There are 5 possible speed taps available on the 5-speed motor with #1 being the lowest airflow and #5 being the highest airflow. These speed selections are preset at the time of manufacture and are easily changed in the field if necessary. Applying 24VAC power between any of the motor taps 1-5 (1/4 in. quick connects) and common will signal the motor to run and regulate torque at the programmed level. The tap input voltage must be in the range 12-33VAC. The 5-speed ECM will have less variation over the operating static pressure range versus a PSC motor as well as a significant watts reduction due to the high motor efficiency. 5-Speed ECM Benefits: - High efficiency - Soft start - 5 speeds with up to 4 speeds on-line - Built in logic allows air flow to change with G, Y1, Y2 and W signals - Super efficient low airflow continuous blower setting (G) Thermal Protection - Motor is electronically protected. Locked Rotor Amps - If motor speed decreases below a programmed stall speed, the motor will shut down and after a delay period, the control will attempt to restart the motor. The 5-speed ECM speed tap selections are as follows: The blue wire should be placed on the speed tap desired for the (G) continuous blower setting – factory wired to Tap 1. If more than one tap are energized at the same time, built in logic gives precedence to the highest tap number and allows air flow to change with G, Y1, Y2 and W signals. Each of those 5 speeds has a specific ‘Torque’ value programmed into the motor for each speed selection. As static pressure increases, airflow decreases resulting in less torque on the rotor. The motor responds only to changes in torque and adjusts its speed accordingly. The red wire should be placed on the speed tap desired during compressor operation (Y1 signal) – factory wired to Tap 3 or 4. The gray wire is not factory wired to the motor and is tied to the wire harness. It is field connected and can be used with 3ht/2cl thermostats or IntelliZone to deliver the required air flow for the Y2 signal. The 5-speed motor is powered by line voltage but the motor speed is energized by 24VAC. The tan wire should be placed on the speed tap desired for auxiliary heat (W signal) – factory wired to Tap 5. Power Connection - 3/16 in. quick connects - Line 1 (orange wire) to L, Ground (green wire) to G, Line 2 (for 208V-230V units) to N (brown wire). 25 RG SERIES INSTALLATION MANUAL Blower Performance Data Variable Speed ECM Motor Model Max esp 015 0.50 018 0.50 023 0.50 024 0.50 030 0.50 036 0.50 041 0.50 042 0.50 042 w/1hp* 0.75 048 0.50 048 w/1hp* 0.75 060 0.75 070 0.75 1 300 L 300 2 400 400 L 400 400 400 3 500 M 500 500 L 500 L 500 L 4 600 H 600 M 600 M 600 M 600 600 650 750 650 750 800 L 650 1000 M 750 800 750 1000 L 900 800 950 850 L 850 L 1100 850 1100 1000 1100 L 950 950 1300 H 950 1300 M 1200 L 1300 5 700 Airflow DIP Switch Settings 6 7 700 H 700 8 9 10 11 12 900 1000 1100 1200 900 1000 1100 1200 1000 1100 1200 1000 1150 900 H 900 M 1250 1100 H 1375 1150 1225 1300 1475 1550 1600 1150 1250 1375 1475 1550 1600 1600 1800 1150 1600 1250 M 1800 1325 1375 1475 1550 H 1600 1600 1700 1850 H 2100 H 2000 2200 2300 2400 1750 M 1950 800 800 H 800 H 800 700 700 M 700 L 1050 M 1050 M 1500 800 1050 L 1500 H 1400 M 1500 1325 H 1325 H 2300 11/10/09 Factory settings are at recommended L-M-H DIP switch locations.

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. NOTE: Refer to the Aurora Base Control Application and Troubleshooting Guide and the Instruction Guide: Aurora Interface and Diagnostics (AID) Tool for additional information. Control Features Software ABC Standard Version 3.0 Single or Dual Capacity Compressors Variable Speed ECM Configuration Mode (If Applicable) Either single or dual capacity compressors can be operated. The control is placed in the ECM configuration mode by holding the pushbutton switch SW1 for 5 to 10 seconds, the high, low, and “G” ECM speeds can be selected by following the LED display lights. LED2 (yellow) will fast flash when entering the 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 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 ECM configuration mode. Aux fan speed will remain at default or current setting and requires the AID Tool for adjustment. Variable Speed ECM Blower Motor Option (If Applicable) A Variable Speed ECM blower motor can be driven directly using the onboard PWM output. Four blower speeds are available based upon the G, Y1, Y2, and W input signals to the board. The blower speeds can be changed either by the ECM manual configurations mode method or by using the Aurora AID Tool directly. All four blower speeds can be set to the same speed if desired. 5-Speed ECM Blower Motor Option (If Applicable) A 5-Speed ECM blower motor will be driven directly using the thermostat connections. Any of the G, Y1, or Y2/W signals can drive any of the 5 available pre-programmed blower speeds on the motor. All 5 Series "G" vintage units will be wired this way at the factory. Reset Configuration Mode The control is placed in reset configuration mode by holding the push button switch SW1 for 50 to 60 seconds. This will reset all configuration settings and the EEPROM back to the factory default settings. LED3 (green) will turn off when entering reset configuration mode. Once LED3 (green) turns off, release SW1 and the control will reset.

T-stat Hum Cmd 32 SW2-4 ON OFF ON OFF SW2-5 ON OFF OFF ON RG SERIES INSTALLATION MANUAL Controls - Aurora Base Control cont. Cycle with Blower - The accessory relay will cycle with the blower output. Lockout – when locked out, the blower will operate continuously in “G” speed, 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. Cycle with Compressor - The accessory relay will cycle with the compressor output. Water Valve Slow Opening - The accessory relay will cycle and delay both the blower and compressor output for 90 seconds. SW2-6 CC Operation – selection of single or dual capacity compressor. 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 Lockout With Emergency Heat - if the control is locked out in the heating mode, and a Y2 or W input 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 ECM blower will shift to “G” speed and PSC blower motor output will remain on. 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. Variable Speed ECM Blower Speeds The blower speeds can be changed either by using the ECM manual configurations mode method or by using the Aurora AID Tool directly (see Instruction Guide: Aurora Interface and Diagnostics (AID) Tool topic). 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. Field Selectable Options via Software (Selectable via the Aurora AID Tool) ECM Blower Speeds 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. An ECM blower motor can be driven directly using the onboard PWM output. Four blower speeds are available, based upon the “G”, Y1 (low), Y2 (high), and Aux input signals to the board. The blower speeds can be changed either by the ECM manual configurations mode method (see ECM Configuration Mode topic) or by using the Aurora AID Tool directly. All four blower speeds can be set to the same speed if desired. Aux blower speed will remain at default or current setting and requires the AID Tool for adjustment. Loss of Charge – fault is recognized when the Normally Closed Low Pressure Switch, P4-7/8 is open prior to the compressor starting. 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. 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. 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. 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. Freeze Detection (Air Coil) - uses 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. 33 RG SERIES INSTALLATION MANUAL Controls - Aurora Base Control cont. 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. 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. Single Compressor Cooling, 2nd Stage (Y1, Y2, 0) The compressor will be staged to full capacity 20 seconds after Y2 input was received. The ECM blower will shift to high speed 15 seconds after the Y2 input was received. Operation Description Dual Compressor Cooling, 2nd Stage (Y1, Y2, O) In dual compressor operation, two ABC boards used in 24 VAC operation, there will be a Y2 call to the Y1 input on the second ABC. The compressor will stage to full capacity 30 seconds after Y1 input is received to the second board. 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. 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. 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 Single Compressor 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 seconds after the Y2 input is received. Dehumidification (Y1, O, DH or Y1, Y2, O, DH) - When a DH command is received from the thermostat during a compressor call for cooling the ECM blower speed will be reduced by 15% to increase dehumidification. Dual Compressor Heating, 2nd Stage (Y1, Y2) In dual compressor operation, two ABC boards used in 24 VAC operation, there will be a Y2 call to the Y1 input on the second ABC. The compressor will stage to full capacity 30 seconds after Y1 input is received to the second board. 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. Single Compressor 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. 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. Dual Compressor Heating, 3rd Stage (Y1, Y2, W) 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 Load Shed - The LS input disables all outputs with the exception of the blower output. When the LS input has been cleared, the anti-short cycle timer and random start timer will be initiated. Input must be tied to common to activate. 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. 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 cycle. 34 RG SERIES INSTALLATION MANUAL Controls - Aurora Base Control cont. Aurora ‘Base’ Control LED Displays Aurora Interface and Diagnostics (AID) Tool 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. 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.

The bolts can then be discarded. • High voltage is correct and matches nameplate. • Fuses, breakers and wire size correct. • Low voltage wiring complete. • Piping completed and water system cleaned and flushed. • Air is purged from closed loop system. • Isolation valves are open, water control valves or loop pumps wired. • Condensate line open and correctly pitched. • Transformer switched to 208V if applicable. • Dip switches are set correctly. • Blower rotates freely – foam shipping support has been removed. • Blower speed correct. • Air filter/cleaner is clean and in position. • Service/access panels are in place. • Return air temperature is between 50-80°F heating and 60-95°F cooling. • Check air coil cleanliness to insure optimum performance. Clean as needed according to maintenance guidelines. To obtain maximum performance the air coil should be cleaned before startup. A 10-percent solution of dishwasher detergent and water is recommended for both sides of coil, a thorough water rinse should follow. Startup Steps NOTE: Complete the Equipment Start-Up/Commissioning Check Sheet during this procedure. Refer to thermostat operating instructions and complete the startup procedure. 1. Initiate a control signal to energize the blower motor. Check blower operation. 2. Initiate a control signal to place the unit in the cooling mode. Cooling setpoint must be set below room temperature. 3. Cooling will energize after a time delay. Check for correct rotation of scroll compressors in 3 phase applications. Incorrect rotation will cause low refrigerant pressures and possibly unusual noise. Switch any two power leads at the compressor or contactor to reverse rotation. 4. Be sure that the compressor and water control valve or loop pump(s) are activated. 5. Verify that the water flow rate is correct by measuring the pressure drop through the heat exchanger using the P/T plugs and comparing to the pressure drop table. 6. Check the temperature of both the supply and discharge water (Refer to Operating Parameters tables). 7. Check for an air temperature drop of 15°F to 25°F across the air coil, depending on the blower speed and entering water temperature. 8. Decrease the cooling set point several degrees and verify high-speed blower operation (Variable speed ECM only). 9. Adjust the cooling setpoint above the room temperature and verify that the compressor and water valve or loop pumps deactivate. 10. Initiate a control signal to place the unit in the heating mode. Heating set point must be set above room temperature. 11. Heating will energize after a time delay. 12. Check the temperature of both the supply and discharge water (Refer to Unit Operating Parameters tables). 13. Check for an air temperature rise of 20°F to 35°F across the air coil, depending on the blower speed and entering water temperature. 14. If auxiliary electric heaters are installed, increase the heating setpoint until the electric heat banks are sequenced on. All stages of the auxiliary heater should be sequenced on when the thermostat is in the Emergency Heat mode. Check amperage of each element. 15. Adjust the heating setpoint below room temperature and verify that the compressor and water valve or loop pumps deactivate. 16. During all testing, check for excessive vibration, noise or water leaks. Correct or repair as required. 17. Set system to desired normal operating mode and set temperature to maintain desired comfort level. 18. Instruct the owner/operator in the proper operation of the thermostat and system maintenance. NOTE: Be certain to fill out and forward all warranty registration papers. 36 RG SERIES INSTALLATION MANUAL Operating Limits Operating Limits Air Limits Min. Ambient Air Rated Ambient Air Max.

If compressor won’t run: 1. 2. 3. 4. 5. 6. 7. 8. 9. The fuse may be open or the circuit breaker is tripped. Check electrical circuits and motor windings for shorts or grounds. Investigate for possible overloading. Replace fuse or reset circuit breakers after fault is corrected. Supply voltage may be too low. Check it with a volt meter. Control system may be faulty. Check control for correct wiring of thermostat or aquastat and check the 24 volt transformer for proper voltage. Wires may be loose or broken. Replace or tighten. The low pressure switch may have tripped due to one or more of the following: a) Heating 1) Plugged heat exchanger on source side 2) Water flow source side - (Low) 3) Water too cold source side 4) Low refrigerant b) Cooling 1) Plugged heat exchanger on load side 2) Water flow load side - (Low) 3) Water too cold load side 4) Low refrigerant The high pressure switch may have tripped due to one or more of the following: a) Heating 1) Plugged heat exchanger on load side 2) Low water flow load side 3) Water too warm load side b) Cooling 1) Plugged heat exchanger on source side 2) Low water flow on source side 3) Water too warm source side The compressor overload protection may be open. The internal winding of the compressor motor may be grounded to the compressor shell. If so, replace the compressor. The compressor winding may be open or shorted. Disconnect power. Check continuity with ohm meter. If the winding is open, replace the compressor. If sufficient cooling or heating is not obtained: 1. 2. 3. 4. Check control for improper location or setting. Check for restriction in water flow. Check refrigerant subcooling and superheat for proper refrigerant charge and expansion valve operation. The reversing valve may be defective and creating a bypass of refrigerant. If the unit will not heat, check the reversing valve coil. If the unit operation is noisy: 1. 2. 3. 4. 5. 6. Check compressor for loosened mounting bolts. Make sure compressor is floating free on its isolator mounts. Check for tubing contact with the compressor or other surfaces. Readjust it by bending slightly. Check screws on all panels. Check for chattering or humming in the contactor or relays due to low voltage or a defective holding coil. Replace the component. Check for proper installation of vibration absorbing material under the unit. Check for abnormally high discharge pressures. Compressor rotation incorrect Refrigerant Systems To maintain sealed circuit integrity, do not install service gauges unless unit operation appears abnormal. Compare the change in temperature on the air side as well as the water side to the Operating Parameters tables. If the unit’s performance is not within the ranges listed, and the airflow and water flow are known to be correct, gauges should then be installed and superheat and subcooling numbers calculated. If superheat and subcooling are outside recommended ranges, an adjustment to the refrigerant charge may be necessary. NOTE: Refrigerant tests must be made with hot water generator turned “OFF”. Verify that air and water flow rates are at proper levels before servicing the refrigerant circuit. 42 RG SERIES INSTALLATION MANUAL Startup and Troubleshooting Form Company Name: _________________________________ Technician Name: ________________________________ Model No: ______________________________________ Owner’s Name: __________________________________ Installation Address: ______________________________ Company Phone No: ______________________________ Date: __________________________________________ Serial No:_______________________________________ Open or Closed Loop: _____________________________ Installation Date: _________________________________ Check One ❑ Start up/Check-out for new installation ❑ Troubleshooting Problem:___________________________________ 1.

Keep all air out of the water. An open loop system should be checked to ensure that the well head is not allowing air to infiltrate the water line. Lines should always be airtight. 2. Keep the system under pressure at all times. It is recommended in open loop systems that the water control valve be placed in the discharge line to prevent loss of pressure during off cycles. Closed loop systems must have positive static pressure. NOTE: On open loop systems, if the installation is in an area with a known high mineral content (125 PPM or greater) in the water, it is best to establish with the owner a periodic maintenance schedule so the coil can be checked regularly. Should periodic coil cleaning be necessary, use standard coil cleaning procedures which are compatible with either the cupronickel or copper water lines. Generally, the more water flowing through the unit the less chance for scaling. Other Maintenance Filters Filters must be clean to obtain maximum performance. They should be inspected monthly under normal operating conditions and be replaced when necessary. Units should never be operated without a filter. Condensate Drain In areas where airborne bacteria produce a slime in the drain pan, it may be necessary to treat chemically to minimize the problem. The condensate drain can pick up lint and dirt, especially with dirty filters. Inspect twice a year to avoid the possibility of overflow. Blower Motors Blower motors are equipped with sealed ball bearings and require no periodic oiling. Hot Water Generator Coil See Water Coil Maintenance section above. Air Coil The air coil must be cleaned to obtain maximum performance. Check once a year under normal operating conditions and, if dirty, brush or vacuum (with a brush attachment) clean. Care must be taken not to damage the aluminum fins while cleaning. CAUTION: Fin edges are sharp. Replacement Procedures Obtaining Parts When ordering service or replacement parts, refer to the model number and serial number of the unit as stamped on the serial plate attached to the unit. If replacement parts are required, mention the date of installation of the unit and the date of failure, along with an explanation of the malfunctions and a description of the replacement parts required.
