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 Btuh 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 (Btuh) + (Blower Power Correction (Watts) x 3.412) • ISO EER Efficiency (W/W) = ISO Cooling Capacity (Btuh) 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 (Btuh) - (Blower Power Correction (Watts) x 3.412) • ISO COP Efficiency (W/W) = ISO Heating Capacity (Btuh) x 3.412 / [Power Input (Watts) - Blower Power Correction (Watts) + Pump Power Correction (Watt)] Comparison of Test Conditions Cooling Entering Air - DB/WB °F Entering Water - °F Fluid Flow Rate Heating Entering Air - DB/WB °F Entering Water - °F Fluid Flow Rate ARI 320 ISO/AHRI 13256-1 WLHP ARI 325 ISO/AHRI 13256-1 GWHP ARI 330 ISO/AHRI 13256-1 GLHP 80/67 85 * 80.6/66.2 86 ** 80/67 50/70 ** 80.6/66.2 59 ** 80/67 77 ** 80.6/66.2 77 ** 70 70 * 68 68 ** 70 50/70 ** 68 50 ** 70 32 ** 68 32 ** 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.

Lockout circuit to shut down unit operation upon receipt of a fault indicator from the safety controls. A 24 volt control circuit allows for safe and easy diagnosis. ASTON SERIES CONSOLE SPECIFICATION CATALOG Controls cont. The user selects either “Heat/Cool” or “Fan Only” on the mode switch, then either “High” or “Low” at the blower speed switch. The temperature can be controlled by rotating the thermostat control unit as well as outputs for status modes, faults and diagnostics. The control system is a microprocessor-based control board that is located in the unit control box. This feature is available for either unit mounted controls or optional remote wall mounted thermostat. A 9-pin low voltage terminal strip provides all necessary terminals for the wall mounted thermostat. Figure 6: Unit Mounted Control Startup The unit will not operate until all the inputs and safety controls are checked for normal operating conditions. Fault Retry All faults are retried twice before finally locking the unit out to prevent nuisance service calls. Component Sequencing Delays knob. Components are sequenced and delayed for optimum unit performance. The “Fan Only” setting provides constant blower operation. Short Cycle Protection and Random Start The control allows a minimum on or off time of 5 minutes for short cycle protection. A random time delay of 0 to 30 seconds is generated after each power-up to prevent simultaneous start up of all units within a building after the release from an unoccupied cycle or power loss. In the “Heat” mode, a call for heat by the thermostat closes the compressor contactor contacts, energizing the compressor, which will run until the thermostat is satisfied. In the “Cool” mode, a call for cooling by the thermostat energizes the reversing valve and closes the compressor contactor contacts, energizing the compressor, which will run until the thermostat is satisfied. Night Setback A grounded signal to common or connecting 24 VAC to the NS terminal will initiate the night setback mode. Load Shed The emergency electric heat operation in the “Heat/Cool” mode is subject to the setting of the internally mounted mode switch. The optional, factory installed electric heat will operate when the internally mounted mode switch is in the “Emergency Heat” mode. In the “Heat” mode, a call for heating energizes the blower and electric heater contactor, energizing the electric heat elements and blower, which will run until the thermostat is satisfied. When the internally mounted mode switch is in the “Normal/Boilerless” mode the unit operates in its normal “Heat/Cool” operation, unless there is an aquastat controller. When the normally open circuit of the aquastat closes and the unit is in the heating mode, it will switch to the “Emergency Heat” condition until the thermostat is satisfied or the aquastat opens restarting the compressor. A grounded signal to common or connecting 24 VAC to the LS terminal places the controller into the load shed mode. The compressor will become disabled and the blower will start upon a thermostat call for heating or cooling. Emergency Shutdown A grounded signal to common or connecting 24 VAC to the ES terminal places the controller into the emergency shutdown mode. The compressor and blower operation are suspended while in the emergency shutdown mode. Condensate Overflow Protection The board incorporates an impedance liquid sensor at the top of the condensate drain pan. Upon a continuous 30-second sensing of the condensate, the cooling operation of the unit is suspended. If either the low or high pressure safety switches are opened, the compressor and reversing valve are disabled by the lockout relay. Unit operation will resume only after the voltage to the unit is interrupted or the mode switch is placed in the “Off” position. Safety Controls The microprocessor board receives separate signals from a high pressure switch for safety, a low pressure switch to prevent loss of refrigerant charge and a low suction temperature thermistor for freeze detection. Upon a continuous 30-second measurement of the fault (immediate for high pressure), compressor operation is stopped. If the electric heat limit switches are opened, the electric heat is disabled.

Display Requires DLI Card/Kit. Up to 2 displays, either 1 local and 1 remote, or 2 remote. (A 2-display configuration requires identical displays.) Local display can be up to 3 meters from the controller, power supply, and data communication. Remote display can be up to 300 meters from the controller. Remote display must be independently powered with data communication done via 3 pole shielded cable. FX10 Advanced Control Overview The Johnson Controls FX10 board is specifically designed for commercial heat pumps and provides control of the entire unit as well as input ports for Open N2, LonTalk, BACnet (MS/TP @ 19,200 Baud rate) communication protocols as well as an input port for a user interface. The user interface is an accessory item that can be used to aid in diagnostics and unit setup. A 16-pin low voltage terminal board provides terminals for common field connections. The FX10 Control provides: • Operational sequencing • High and low-pressure switch monitoring • General lockout • Freeze detection • Condensate overflow sensing • Lockout mode control • Emergency shutdown mode • Random start and short cycle protection Control Timing & Fault Recognition Delays Lead compressor “ON” delay.............................................90 seconds (not applicable for single compressor models) Minimum compressor “ON” time............................................2 minutes (except for fault condition) Short cycle delay...................................................................5 minutes Random start delay.......................................................0-120 seconds High pressure fault.............................................................. <1 second Low pressure fault..............................................................30 seconds Freeze detection fault........................................................30 seconds Condensate overflow fault..................................................30 seconds Low pressure fault bypass.....................................................2 minutes Freeze detection fault bypass...............................................2 minutes Optional FX10 Microprocessor and BAS Interface The FX10 is a microprocessor based control that not only monitors and controls the heat pump but also can communicate any of this information back to the building automation system (BAS). This means that not only does the control monitor the heat pump at the unit you can also monitor and control many the features over the BAS. This clearly puts the FX10 in a class of its own. Short Cycle Protection Allows a minimum compressor “off” time of four minutes and a minimum “on” time of two minutes. Random Start A delay of 1 to 120 seconds is generated after each power-up to prevent simultaneous startup of all units within a building after the release from an unoccupied cycle or power loss. Emergency Shutdown A field-applied dry contact can be used to place the control into emergency shutdown mode. During this mode, all outputs on the board are disabled. 12 ASTON SERIES CONSOLE SPECIFICATION CATALOG Controls - FX10 cont. Control and Safety Feature Details The control will enumerate all fault conditions (HP, LP, CO, LOC, and freeze detection) over a BAS as well as display them on a medium user interface (MUI). HP, LP, CO and freeze detection faults can all be reset over a BAS. A Loss Of Charge fault can not be reset or bypassed until the problem has been corrected. A MUI is invaluable as a service tool for the building service team. Emergency Shutdown The emergency shutdown mode can be activated by a command from a facility management system or a closed contact on BI-2. The default state for the emergency shutdown data point is off. When the emergency shutdown mode is activated, all outputs will be turned off immediately and will remain off until the emergency shutdown mode is de-activated. The first time the compressor starts after the emergency shutdown mode has been de-activated, there will be a random start delay present. The unit can be commanded to run by a typical heat pump thermostat or run based on heating and cooling set points supplied by a BAS. The control board is wired with quick connect harnesses for easy field change out of a bad control board. All ECM2.3 variable blower speed settings can be changed over a BAS or with a MUI. The control has an input programmed to enable field installed emergency heat in the event that the compressor is locked out. This input can also be commanded on from a BAS as needed. An alarm history can be viewed through the MUI and will be held in memory until the unit is power cycled. Relative humidity can be read by a 0-5VDC humidity sensor that is displayed over the network. If you are using an ECM2.3 blower motor the control can enable dehumidification mode based on a set point in the control. The dehumidification set point itself can also be changed over a BAS or with a MUI. Dehumidification mode can also be enabled by the BAS. Because the FX10 is not factory configured to read CO2 levels, contact the factory for application assistance. Lockout Mode Lockout mode can be activated by any of the following fault signals: refrigerant system high pressure, refrigerant system low pressure, freeze detection , and condensate overflow. When any valid fault signal remains continuously active for the length of its recognition delay, the controller will go into fault retry mode, which will turn off the compressor. After the Compressor short cycle delay, the compressor will attempt to operate once again. If three consecutive faults occur in 60 minutes during a single heating or cooling demand, the unit will go into lockout mode, turning off the compressor, enabling the alarm output, and setting the blower back to low speed operation until the controller is reset. If the control faults due to the low pressure input (BI-3) being open during the pre-compressor startup check, the control will go into lockout mode immediately, disabling the compressor from starting and enabling the alarm output (BO-6). The lockout condition can be reset by powering down the controller, by a command from the BAS, or by the holding the ESC and Return keys on the MUI for 5 seconds. The FX10 control has unused analog and digital inputs for field installed items such as air temperature, water temperature, CO2 or current status switches. The control has unused binary and PWM outputs that can be commanded over the BAS for field use. An optional Medium User Interface (MUI) for control setup and advanced diagnostics is available with some mounting kits, MUIK1 - Panel mount version and the MUIK2-Wall mount version. Freeze Detection Limit (AI-5) The freeze detection limit sensor will monitor the liquid refrigerant temperature entering the water coil in the heating mode. If the temperature drops below the freeze detection limit trip point for the recognition delay period, the condition will be recognized as a fault. The freeze detection limit trip point will be factory set for 30°F and will be field selectable for 15°F by removing a jumper wire on BI-5. The freeze detection limit fault condition will be bypassed 2 minutes at normal compressor startup, to allow the refrigeration circuit to stabilize. If the freeze detection limit sensor becomes unreliable at any time compressor operation will immediately be suspended until the problem is corrected. This should be displayed as an alarm on the BAS and the MUI. This alarm will be reported a “Water Low Temp Limit” fault. Zone Sensors There are two options for zone sensors that can be used with the FX10 control. Both sensors use a Johnson controls A99 positive temperature coefficient type sensor. The TAXXJ02 has a set point adjustment now which will give the end user a +/- 5°F adjustment from the set point as well as a push button that can be used for temporary occupancy. The control leaves the factory set to operate with a TAXXJ02 sensor and can be changed to read the TAXXA01 sensor through a building automation system or with a user interface. Standard Features • • • • • • • • • • High Pressure (BI-11) Anti Short Cycle High Pressure Protection Low Pressure Protection Freeze Detection Loss Of Charge Detection Random Start Display for diagnostics Reset Lockout at disconnect or through BAS 2 Accessory outputs Optional BAS add-on controls The high-pressure switch shall be a normally closed (NC) switch that monitors the systems refrigerant pressure. If the input senses the high-pressure switch is open it must disable the compressor output immediately and count the fault. The compressor minimum on time does not apply if the high-pressure switch opens. The compressor will not restart until the compressor short cycle time delay has been satisfied. Low Pressure (BI-3) The low-pressure switch shall be a normally closed (NC) switch that monitors the systems refrigerant pressure. The input shall be 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. DDC Operation & Connection Other optional network protocol boards that can be added to FX10: • Johnson Control N2 • LonWorks • BACnet - MS/TP @ 19,200 Baud rate - Limit devices to 40 on a single trunk line. 13 ASTON SERIES CONSOLE SPECIFICATION CATALOG Controls - FX10 cont. Condensate Overflow Compressor Short Cycle Delay Time The condensate overflow sensing circuit will monitor the condensate level as a resistance input to AI-3. If the condensate water level rises resulting in the input resistance rising above the set point for the recognition delay period, the condition will be recognized as a fault. The condensate will be subjected to a (30) second lockout delay which requires that the fault be sensed for a continuous (30) seconds before suspending unit operation. The compressor short cycle time delay will ensure that the compressor output will not be enabled for a minimum of (5) minutes after it is disabled. This allows for the system refrigerant pressures to equalize after the compressor is disabled. Heating Cycle On a call for heating, the blower enable output and accessory output 2 will turn on immediately after the random start delay timer has been satisfied. If the compressor short cycle time delay has been satisfied, the compressor will turn on after the blower enable and accessory output 2 are on and the fixed compressor start delay timers have been satisfied. Alarm Output (BO-6) The alarm output will be enabled when the control is in the lockout mode and will be disabled when the lockout is reset. Test Mode Raising the zone temperature input (AI-1) reading to 180–220°F or by holding the ESC and down arrow keys on the MUI for 5 seconds will put the control into test mode. In test mode the random start delay and the compressor fixed on delay time will both be shortened to 5 seconds and the reversing valve will be allowed to cycle with out shutting down the compressor. If an MUI is connected to the control LED 8 will flash and the words “Test Mode Enabled” will be shown on the LCD display when the control is in test mode. Test mode will be disabled after a power cycle, 30 minute timeout, or by holding the ESC and Up arrow keys on the MUI. Auxiliary heat output can be controlled over the BAS. Set Point Control Mode In set point control mode the reversing valve output will be disabled. As the temperature drops below the heating set point and begins to operate in the heating 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. The compressor must be operating in low capacity for a minimum of 30 seconds before the full capacity compressor output can be enabled. During low capacity compressor operation the ECM2.3 blower will operate in medium speed and will operate in high speed when the compressor is operating at full capacity. Sequence of Operation Power Fail Restart When the controller is first powered up, the outputs will be disabled for a random start delay. The delay is provided to prevent simultaneous starting of multiple heat pumps. Once the timer expires, the controller will operate normally. Thermostat Control Mode In thermostat mode the compressor will be cycled based on Y1 and Y2 calls from a room thermostat. When the control receives a Y1 command (BI-7) from the thermostat the low capacity compressor output (BO2) will be enabled and the ECM2.3 blower will operate in medium speed. When the control receives a Y2 command (BI-8) from the thermostat the full capacity compressor output will be enabled and the ECM2.3 blower will operate in high speed. During the heating cycle the reversing valve will be commanded into the off position. Random Start Delay This delay will be used after every power failure, as well as the first time the compressor is started after the control exits the unoccupied mode or the emergency shutdown mode. The delay should not be less than 1 second and not longer than 120 seconds. If the control is in test mode the random start delay will be shortened to 5 seconds. Compressor Fixed On Delay Time Cooling Cycle The Compressor Fixed On Delay Time will ensure that the compressor output (B02) is not enabled for (90) seconds after the control receives a call to start the compressor. This delay is adjustable from 30 – 300 seconds over a BAS or a MUI. If the control is in test mode the Compressor Fixed On Delay Timer will be shortened to 5 seconds. On a call for cooling, the blower enable output and accessory output 2 will turn on immediately after the random start delay timer has been satisfied. If the compressor short cycle time delay has been satisfied, the compressor will turn on after the blower enable and accessory output 2 are on and the fixed compressor start delay timers have been satisfied. Compressor Minimum On Delay 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. The compressor must be operating in low capacity for a minimum of 30 seconds before the full capacity compressor output can be enabled. During low capacity compressor operation the ECM2.3 blower will operate in medium speed and will operate in high speed when the compressor is operating at full capacity. The compressor minimum on delay will ensure that the compressor output is enabled for a minimum of (2) minute each time the compressor output is enabled. This will apply in every instance except in the event the high pressure switch is tripped or emergency shutdown then the compressor output will be disable immediately. 14 ASTON SERIES CONSOLE SPECIFICATION CATALOG Controls - FX10 cont. Inputs & Outputs Configuration Thermostat Control Mode In thermostat mode the compressor will be cycled based on Y1 and Y2 calls from a room thermostat. When the control receives a Y1 command (BI-7) from the thermostat the low capacity compressor output (BO2) will be enabled and the ECM2.3 blower will operate in medium speed. When the control receives a Y2 command (BI-8) from the thermostat the full capacity compressor output will be enabled and the ECM2.3 blower will operate in high speed. During the cooling cycle the reversing valve will be commanded into the “ON” position. Field Selectable Options Freeze Detection Limit Set Point (BI-5) The freeze detection limit set point input allows you to adjust the freeze detection limit set point (AI-5). When the jumper is installed on BI-5 (Wire #24) the freeze detection limit set point is factory set for 30°F. When the jumper on BI-5 (Wire #24) is removed the freeze detection limit set point will be 15°F. Accessory Outputs (BO-7 and BO-8) Accessory Output 1 will be energized 90 seconds prior to the compressor output being energized. Accessory Output 2 will be energized with the blower output (BO-1). When the corresponding compressor output is turned off the accessory output will be deactivated immediately. These outputs are selectable for normally open or normally closed operation through the Medium User interface or through the Building Automation System. ECM2.3 Blower Operation Blower speeds will be selected through the user interface or the facility management system. There will be a total of 12 speeds selectable with only three being selected at any one time. The lowest numbered speed selection set to ON will select the lowspeed blower setting, the middle selection set to ON will select the medium-speed blower setting and the highest selection set to ON will select the high-speed blower setting. If all selections are set to OFF the software shall select speed setting 10 for low-speed, 11 for medium-speed, and will select speed setting 12 for high speed. If only one selection is set to ON, that selection will set the low-speed blower setting, the medium-speed setting will be 11, and the highspeed setting will be speed 12. The maximum low-speed setting will be speed 10 and the minimum high-speed setting will be speed 3. In addition there is a low limit setting in the software to prevent the ECM2.3 blower speed from being set below acceptable limits for each unit size. Control Accessories Zone Sensors • TAXXJ02 Room Command Module • TAXXA01 LCD Room Command Module • A99 Sensor MUI (LCD User interface) for diagnostics and commissioning. • MUIK3 - Panel Mount, Portable • MUIK4 - Wall Mount ECM2.3 Blower air flow “Soft Switch Settings” SINGLE and DUAL STAGE WATER-TO-AIR A set of 12 “soft switches” accessible through the user interface or building automation system are used to select the three blower speed settings for the ECM2.3 blower motor. The 12 soft switches work in exactly the same way as the hardware switches used on the Premier control (Refer to Blower Performance Data - ECM2.3 Motor for proper settings). No more than three soft switches may be set to the “ON” position. The first “ON” switch (the lowest number switch) determines the “low speed fan” setting. The second determines the “medium speed fan” setting, and the third determines the “high speed fan” setting. Emergency Heat/Network Enabled Output (BO5) This output is set from the factory to enable/disable emergency heat. If a problem occurs with the unit resulting in the compressor being locked out in heating mode, the control will automatically enable this output to turn on field installed electric heat. This output is interlocked with the blower proving input BI-6 (Blower proving sensors must be field supplied and installed). BI-6 must be connected to PB2 position 3 (see unit schematic) in the field if no blower proving sensor is desired. There is a configurable parameter available through a BAS network that must be enabled if this output is to be commanded over the BAS network. MUI Alarm History Reporting If a fault occurs the fault will be recorded in history for display on the medium user interface in the History Menu. Each fault type will be displayed in the history menu with a number between 0 and 3. A reading of 3+ will mean that fault has occurred more than three times in the past. The history menu can be cleared with a power cycle only.

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. A decentralized system also means if one unit should fault, the rest of the system will continue to operate normally, as well as eliminating air cross-contamination problems and expensive high pressure duct systems requiring an inefficient electric resistance reheat mode. The basic principle of a water source heat pump is the transfer of heat into water from the space during cooling, or the transfer of heat from water into the space during heating. Extremely high levels of energy efficiency are achieved as electricity is used only to move heat, not to produce it. Using a typical G Series, one unit of electricity will move four to five units of heat. When multiple water source heat pumps are combined on a common circulating loop, the ultimate in energy efficiency is created: Units on cooling mode are adding heat to the loop which the units in heating mode can absorb, thus removing heat from the area where cooling is needed, recovering and redistributing that heat for possible utilization elsewhere in the system. In modern commercial structures, this characteristic of heat recovery from core area heat generated by lighting, office equipment, computers, solar radiation, people or other sources, is an important factor in the high efficiency and low operating costs of closed source heat pump systems. The G Series Approach There are a number of proven choices in the type of G Series system which would be best for any given application. Most often considered are: Vertical - Closed Loop/Ground Source Return Water Heater/ Rejector G Series Unit G Series Unit G Series Unit G Series Unit G Series Unit G Series Unit Pumps Supply Water In the event that a building's net heating and cooling requirements create loop temperature extremes, G Series units have the extended range capacity and versatility to maintain a comfortable environment for all building areas. Excess heat can be stored for later utilization or be added or removed in one of three ways; by ground-source heat exchanger loops: plate heat exchangers connected to other water sources, or conventional cooler/boiler configurations. Your representative has the expertise and computer software to assist in determining optimum system type for specific applications. • Closed Loop/Ground-Source Systems utilize the stable temperatures of the earth to maintain proper water source temperatures (via vertical or horizontal closed loop heat exchangers) for G Series extended range heat pump system. Sizes range from a single unit through many hundreds of units. When net cooling requirements cause closed loop water temperatures to rise, heat is dissipated into the cooler earth through buried high strength plastic pipe “heat exchangers.” Conversely if net space heating demands cause loop heat absorption beyond that heat recovered from building core areas, the loop temperature will fall causing heat to be extracted from the earth. Due to the extended loop temperatures, AHRI/ISO 13256-1 Ground Loop Heat Pumps are required for this application. Because auxiliary equipment such as a fossil fuel boiler and The Closed Loop Advantage A properly applied water source heat pump system offers many advantages over other systems. First costs are low because units can be added to the loop on an “as needed basis”- perfect for speculative buildings. Installed costs are low since units are self-contained and can be located adjacent to the occupied space, requiring minimal ductwork. Maintenance can be done on individual units without system shut-down. Conditions remain 16 ASTON SERIES CONSOLE SPECIFICATION CATALOG Application Notes cont. cooling tower are not required to maintain the loop temperature, operating and maintenance costs are very low. Plate Heat Exchanger - Closed Loop/Ground Water Ground-source systems are most applicable in residential and light commercial buildings where both heating and cooling are desired, and on larger envelope dominated structures where core heat recovery will not meet overall heating loads. Both vertical and horizontally installed closed-loops can be used. The land space required for the “heat exchangers” is 100-250 sq. ft./ton on vertical (drilled) installations and 750-1500 sq. ft./ton for horizontal (trenched) installations. Closed loop heat exchangers can be located under parking areas or even under the building itself. On large multi-unit systems, sizing the closed loop heat exchanger to meet only the net heating loads and assisting cooling loads with a closed circuit cooling tower may be the most cost effective choice. Surface Water - Closed Loop/Ground Source • Closed Loop/Ground Water Plate Heat Exchanger Systems utilize lake, ocean, well water or other water sources to maintain closed loop water temperatures in multi-unit G Series systems. A plate frame heat exchanger isolates the units from any contaminating effects of the water source, and allows periodic cleaning of the heat exchanger during off peak hours. Operation and benefits are similar to those for ground-source systems. Due to the extended loop temperatures, AHRI/ ISO 13256-1 Ground Loop Heat Pumps are required for this application. Closed loop plate heat exchanger systems are applicable in commercial, marine, or industrial structures where the many benefits of a water source heat pump system are desired, regardless of whether the load is heating or cooling dominated. • Closed Loop/Ground-Source Surface Water Systems also utilize the stable temperatures of Surface Water to maintain proper water source temperatures for G Series extended range heat pump systems. These systems have all of the advantages of horizontal and vertical closed loop systems. Due to the extended loop temperatures, AHRI/ISO 13256-1 Ground Water or Ground Loop Heat Pumps are required for this application. In cooling dominated structures, the ground-source surface water systems can be very cost effective especially where local building codes require water retention ponds for short term storage of surface run-off. Sizing requirements for the surface water is a minimum of 500 sq. ft./lon of surface area at a minimum depth of 8 feet. WaterFumace should be contacted when designs for heating dominated structures are required. 17 ASTON SERIES CONSOLE SPECIFICATION CATALOG 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°r 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. Due to the moderate loop temperatures, AHRI/ISO 13256-1 Water Loop Heat Pumps are required for this application. Cooler/Boiler - Closed Loop Water Quality In areas with extremely hard water, the owner should be informed that the heat exchanger may require occasional flushing. 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 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 loss of warranty.

If applicable, turn off the accessory heater power switch. Electrical shock could cause personal injury. Unit Location Locate the unit in an indoor area that allows for easy removal of the filter and access panels. Location should have enough space for service personnel to perform maintenance or repair. Provide sufficient room to make water and electrical connection(s). Any access panel screws that would be difficult to remove after the unit is installed should be removed prior to setting the unit. 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. 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. Follow all safety codes. Wear safety glasses and work gloves. Use a quenching cloth for brazing operations and have a fire extinguisher available. Installing Console Units Console units are available in left or right air return configurations. Units should be mounted level on the floor. It is not necessary to anchor the unit to the floor.

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. Check carefully for water leaks. Piping is usually design as ‘reverse return’ to equalize flow paths through each unit. A short flexible pressure rated hose is used to make connection to the fixed building piping system. This hose is typically stainless steel braid and includes a swivel fitting on one end for easy removal and is flexible to help isolate the unit for quieter operation . Isolation valves for servicing, y-strainers for filtering and memory-stop flow valve or a balancing valve can be provided for consistent water flow through the unit. Condensate Drain On console units, the internal condensate drain assembly consists of a drain tube which is connected to the drain pan. A condensate tube is inside all cabinets as a trapping loop; therefore, an external trap is not necessary. All unit source water connections 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. The open and closed loop piping system should include pressure/temperature 19 ASTON SERIES CONSOLE SPECIFICATION CATALOG 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. WFI Select computer software selection program can then be used to develop an accurate and complete heat pump schedule. WFI Select can be obtained from your local representative. be selected on cooling capacity only since the heating output is usually greater than the cooling capacity. Step 6: Determine the correction factors associated with the variable factors of dry bulb and wet bulb. Corrected Total Cooling = tabulated total cooling x wet bulb correction. Corrected Sensible Cooling = tabulated sensible cooling x wet/dry bulb correction. While WFI Select is the easiest and most accurate method to size and select equipment, however, selection can still be accomplished manually using this manual and the following selection procedure. Sizing so that the actual sensible capacity of the equipment will satisfy the sensible capacity of the zone is the recommended method for best results. Step 7: Compare the corrected capacities to the load requirements. Normally if the capacities are within 10% of the loads, the equipment is acceptable. It is better to undersize than oversize, as undersizing improves humidity control, reduces sound levels and extends the life of the equipment. Boiler/Tower Application Typical boiler/tower application will result in entering water temperatures of 60-90°F with 70°F for heating and 90°F for cooling. Water to refrigerant insulation option would not be required. Flow rates are 2.5 to 3 gpm per ton with 2.5 gpm per ton often representing an economical design point. Step 8: When complete, calculate water temperature rise and assess the selection. If the units selected are not within 10% of the load calculations, then review what effect changing the GPM, water temperature and/or air flow and air temperature would have on the corrected capacities. If the desired capacity cannot be achieved, select the next larger or smaller unit and repeat the procedure. Remember, when in doubt, undersize slightly for best performance. Geothermal Application Typical geothermal application can result in a wide entering water temperature range of 30-100°F. Typically minimum heating entering water temperatures can range from 30 to 50°F depending upon loop type and geographical location. Cooling performance should be calculated using a maximum loop temperature of 100°F in most loop applications. Water flow is typically 2.5 to 3 gpm per ton with 3 gpm per ton recommended with the more extreme loop temperatures. PLEASE NOTE THAT WATER COIL INSULATION OPTION SHOULD BE SELECTED WHEN ENTERING WATER TEMPERATURES ARE EXPECTED TO BE BELOW 45-50°F. Example Equipment Selection - Cooling 1.

Design Conditions: Similarly, we have also obtained the following design parameters: Entering Water Temp.............................................................100°F Water Flow (Based upon 10°F rise in temp.) 5.5 GPM Air Flow Required............................................................ 450 CFM Step 1: Determine the actual heating and cooling loads at the desired dry bulb and wet bulb conditions. Step 2: Obtain the following de sign parameters: Entering water temperature, water flow rate in GPM, air flow in CFM, water flow pressure drop and design wet and dry bulb temperatures. Air flow CFM should be between 300 and 450 CFM per ton. Unit water pressure drop should be kept as close as possible to each other to make water balancing easier. Go to the appropriate tables and find the proper indicated water flow and water temperature. 3, 4 & 5. HP Selection: After making our preliminary selection (GC18), we enter the tables at design water flow and water temperature and read Total Cooling, Sens. Cooling and Heat of Rej. capacities: Total Cooling............................................................. 16,600 BTUH Sensible Cooling...................................................... 12,600 BTUH Heat of Rejection...................................................... 21,400 BTUH Step 3: Select a unit based on total and sensible cooling conditions. Select a unit which is closest to, but no larger than, the actual cooling load. Step 4: Enter tables at the design water flow and water temperature. Read the total and sensible cooling capacities (Note: interpolation is permissible, extrapolation is not). 6 & 7. Entering Air and Airflow Corrections: Next, we determine our correction factors. (Refer to Correction Factor Tables - Air Flow and Entering Air correction tables — using 450 cfm. or 450÷500 nom. = 90%). Corrected Total Cooling = 16,600 x 0.982 x 0.897 = 14,622 Corrected Sens Cooling = 12,600 x 0.933 x 0.995 = 11,697 Corrected Heat of Reject = 21,400 x 0.980 x 0.895 = 18,770 Step 5: Read the heating capacity. If it exceeds the design criteria it is acceptable. It is quite normal for water source heat pumps to 20 ASTON SERIES CONSOLE SPECIFICATION CATALOG Selection Example cont. 8. Water Temperature Rise Calculation & Assessment: Note: 500 = parameters for water & 485 = parameters for antifreeze solutions to 30% weight. HR = 500 x GPM x (Tin - Tout) HR = (Tin - Tout) or ∆T Rise 500 x GPM 18,770 = 6.83 °F Rise 500 x 5.5 When we compare the Corrected Total Cooling and Corrected Sensible Cooling figures with our load requirements stated in Step 1, we discover that our selection is within +10% of our sensible load requirement. Further more, we see that our Corrected Total Cooling figure is within 1,000 Btuh of the actual indicated load. Antifreeze Corrections Catalog performance can be corrected for antifreeze use.

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. 31 ASTON SERIES CONSOLE SPECIFICATION CATALOG GC09 - Performance Data 300 Rated CFM Heating / Cooling EWT °F 20 30 40 50 60 70 80 90 100 110 120 Flow Rate GPM Water Pressure Drop PSI FT/HD 1.2 1.1 2.5 1.8 2.4 5.6 2.5 3.8 8.8 Performance capacities shown in thousands of Btuh.
