RG SERIES ENGINEERING GUIDE Controls - Aurora Base Controls Aurora ‘Base’ Control Field Selectable Options via Hardware DIP Switch (SW1) – Test/Configuration Button (See SW1 Operation Table) Test Mode The control is placed in the test mode by holding the push button switch 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.
RG SERIES ENGINEERING GUIDE Controls - Aurora Base Controls 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.
RG SERIES ENGINEERING GUIDE Controls - Aurora Base Controls 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 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.
RG SERIES ENGINEERING GUIDE Controls - Aurora Base Controls 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.

RG SERIES ENGINEERING GUIDE Controls - FX10 (optional) cont. checked 15 seconds before compressor start up to be sure the pressure switch is closed and then ignored for the first 2 minutes after the compressor output (BO-2) is enabled. If the switch is open continuously for (30) seconds during compressor operation the compressor output (BO-2) will be disabled. The compressor will not restart until the compressor short cycle time delay has been satisfied.
RG SERIES ENGINEERING GUIDE Controls - FX10 (optional) cont. Set Point Control Mode In set point control mode the reversing valve output will be enabled. As the temperature falls below the cooling set point and begins to operate in the cooling proportional band, the low capacity compressor output (BO-2) will be enabled. A PI loop in the programming of the control will determine when the full capacity compressor output (BO-4) is to be enabled.
RG SERIES ENGINEERING GUIDE Controls - FX10 (optional) cont. Emergency Heat/Network Enabled Output (BO5) Inputs and Outputs Configuration This output is set from the factory to enable/disable emergency heat.

RG SERIES ENGINEERING GUIDE Hot Gas Reheat Dehumidification Overview Hot Gas Reheat Dehumidification Overview Dehumidification - The Need for Reheat With tighter construction and more and more ventilation air being introduced into buildings, there is more need now than ever for proper humidity control. Ensuring dehumidification can provide consistent employee comfort, a reduction in mold liability, a reduction in cooling costs.
RG SERIES ENGINEERING GUIDE Hot Gas Reheat Dehumidification Overview cont. Hot Gas Reheat Dehumidification Overview cont. Variable speed ECM models will generally compensate up to their maximum ESP of 0.5 in. wg. for 1/2 hp and 0.75 in. wg. for 1 hp. Btu/hr may be converted to lbs/hr or grains per hour as shown in the equations below. Model VS048, 1500 cfm, H x W = SA 20 x 40 = 800 in.2 = 5.56 ft.2 11,900 Btu/h / 1,069 Btu/lb of water vapor at 80/67 DB/WB°F = 11.
RG SERIES ENGINEERING GUIDE Hot Gas Reheat - Controls The reheat option is available with the Aurora or FX10 control. Three control schemes are available: Dehumidification Mode Operation Upon a call for dehumidification, the blower relay and reversing valve coil are energized immediately, and the compressor contactor will energize after a 90 second delay. The reheat valve coil will energize once the compressor has been operational for 30 seconds.
RG SERIES ENGINEERING GUIDE Application Notes on individual units without system shut-down. Conditions remain comfortable since each unit operates separately, allowing cooling in one area and heating in another. Tenant spaces can be finished and added as needed. Power billing to tenants is also convenient since each unit can be individually metered: each pays for what each uses. Nighttime and/or weekend uses of certain areas are possible without heating or cooling the entire facility.
RG SERIES ENGINEERING GUIDE Application Notes cont. Because auxiliary equipment such as a fossil fuel boiler and cooling tower are not required to maintain the loop temperature, operating and maintenance costs are very low. surface run-off. Sizing requirements for the surface water is a minimum of 500 sq. ft./ton of surface area at a minimum depth of 8 feet. Your sales representative should be contacted when designs for heating dominated structures are required.
RG SERIES ENGINEERING GUIDE Application Notes cont. • Closed Loop /Cooler-Boiler Systems utilize a closed heat recovering loop with multiple water source heat pumps in the more conventional manner. Typically a boiler is employed to maintain closed loop temperatures above 60°F and a cooling tower to maintain loop temperatures below 90°F. These systems are applicable in medium to large buildings regardless of whether the load is heating or cooling dominated.

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.
RG SERIES ENGINEERING GUIDE Installation Notes cont. Ductwork • Ensure return air grilles will not allow line of site noise to transfer to adjacent space. Use a sound barrier or some other material to isolate the grille from the unit. A supply grille, boot and short piece of flex duct pointed away from the unit can greatly attenuate equipment noise. • Use a canvas isolation duct connector at the supply and return duct connection of the unit.

The ABC board’s Yellow Config LED will flash the current variable speed ECM blower speed selections for low, med, 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 variable speed ECM blower motor speeds can be field adjusted with or without using an AID Tool.
RG SERIES ENGINEERING GUIDE Selection Example To achieve optimal performance, proper selection of each heat pump is essential. A building load program should be used to determine the heating and cooling load of each zone. A computer software selection program can then be used to develop an accurate and complete heat pump schedule. Software can be obtained from your local commercial representative. Step 4: Enter tables at the design water flow and water temperature.
RG SERIES ENGINEERING GUIDE Selection Example cont. 3, 4 & 5. HP Selection: HR = 500 x gpm x (Tin - Tout) HR = (Tin - Tout) or ¨T Rise 500 x gpm After making our preliminary selection (US*060 ECM), we enter the tables at design water flow and water temperature and read Total Cooling, Sens.
