AHI Data cont. The performance standard AHI/ASHAE/ISO 13256-1 became effective January 1, 2000 and replaces AHI Standards 320, 325, and 330. This new standard has three major categories: Water Loop (comparable to AI 320), Ground Water (AI 325), and Ground Loop (AI 330). Although these standards are similar there are some differences: Unit of Measure: The ooling OP The cooling efficiency is measured in EE (US version measured in Btu/h per Watt. The Metric version is measured in a cooling OP (Watt per Watt) similar to the traditional OP measurement. Water onditions 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 ) water rounded down from the old 70 F (21.1 ). Air onditions 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 ) dry bulb and 66.2 F (19 ) wet bulb entering air instead of the traditional 80 F (26.7 ) DB and 67 F (19.4 ) 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 orrection alculation 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 orrection alculation 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 EE and OPs fairly dramatically over AI 320, 325, and 330 ratings. Blower Power orrection = (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 apacity and Efficiency alculations The following equations illustrate cooling calculations: ISO ooling apacity = ooling apacity (Btu/h) + (Blower Power orrection (Watts) x 3.412) ISO EE Efficiency (W/W) = ISO ooling apacity (Btu/h) x 3.412 / [Power Input (Watts) - Blower Power orrection (Watts) + Pump Power orrection (Watt)] The following equations illustrate heating calculations: ISO Heating apacity = Heating apacity (Btu/h) - (Blower Power orrection (Watts) x 3.412) ISO OP Efficiency (W/W) = ISO Heating apacity (Btu/h) x 3.412 / [Power Input (Watts) - Blower Power orrection (Watts) + Pump Power orrection (Watt)] omparison of Test onditions AI 320 ISO/AHI 13256-1 WLHP AI 325 ISO/AHI 13256-1 GWHP AI 330 onversions: Airflow (lps) = cfm x 0.472; Water Flow (lps) = gpm x 0.0631; esp (Pascals) = esp (in wg) x 249; Press Drop (Pascals) = Press Drop (ft hd) x 2990 ISO/AHI 13256-1 GLHP ooling Entering Air - DB/WB F 80/67 80.6/66.2 80/67 80.6/66.2 80/67 80.6/66.2 Entering Water - F 85 86 50/70 59 77 77 Fluid Flow ate * ** ** ** ** ** Heating Entering Air - DB/WB F 70 68 70 68 70 68 Entering Water - F 70 68 50/70 50 32 32 Fluid Flow ate * ** ** ** ** ** 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.

The optional performance monitoring kit includes entering and leaving water temperatures along with source water flow rate via a vortex shedding flow meter. The Aurora Advanced VS ontrol uses an internal PID control and communicates via Modbus to the variable speed compressor drive and electronic expansion valve to provide capacity and superheat control of the system. All faults codes from the compressor drive are mapped to the Aurora system which are then displayed through the AID tool. Optional Aurora UP When coupled with the optional Aurora UP, the system can communicate all of these same heat pump parameters to the BAS as network points using either BAnet, N2 or Lon protocols. This means that not only are heat pump parameters visible by the BAS, many configuration settings, such as airflow and freeze detection settings, can also be changed from the BAS system saving commissioning costs. This provides both cost advantages and features not typically found on WSHP controls. All configuration, sensor and servicing can be accessed thru the AuroraTouch color service tool. This integration allows heat pump monitoring sensors, status and service diagnosis faults to be communicated thru the DD direct to the building automation system (BAS), giving building supervisors detailed and accurate information on every piece of equipment without removing an access panel! ontrol Features Software AB Standard Version 3.0 Variable Speed ompressors Only opeland EV2 Variable Speed compressors can be operated.

ontrols - Aurora Advanced Variable Speed ontrol cont. Variable Speed EM Blower Motor A variable speed EM blower motor is driven directly using the onboard PWM output. Multiple blower speeds are available based upon requirements of the compressor and electric heat. The blower speeds can be changed either by the variable speed EM manual configurations mode method or by using the Aurora AID Tool directly, or with the Auorra/UP via BAS. Advanced Hot Water Generator ontrol (Domestic Hot Water Option) An AID Tool selectable temperature limit and microprocessor control of the process is featured. This will maximize hot water generation and prevent undesirable energy use. An alert will occur when the hot water input temperature is at or above the set point (130 F default) for 30 continuous seconds. This alert will appear as an E15 on the AID Tool and the hot water pump de-energizes. Hot water pump operations resume on the next compressor cycle or after 15 minutes of continuous compressor operation during the current thermostat demand cycle. Since compressor hot gas temperature is dependent on loop temperature in cooling mode, loop temperatures may be too low to allow proper heating of water. The control will monitor water and refrigerant temperatures to determine if conditions are satisfactory for heating water. VS Drive and Envelope ontrol The VS drive operates the compressor between 25 and 100% capacity. The VS drive communicates any out of refrigerant envelope conditions to the Aurora and will attempt to adjust the compressor speed to keep within the envelope. These conditions are measured using discharge temperature and current sensors of the drive. Electronic Expansion Valve (EEV) The electronic expansion valve (EEV) is operated by the AXB board and is set to maintain optimal superheat setting for maximum efficiency. All operation parameters are communicated to the Aurora system. Variable Speed Pump This input and output are provided to drive and monitor a variable speed pump. The VS pump output is a PWM signal to drive the variable speed pump. The minimum and maximum level are set using the AID Tool. 50% and 100% are the default settings respectively. The VS data input allows a separate PWM signal to return from the pump giving fault and performance information. Fault received from the variable speed pump will be displayed as E16. Loop Pump Linking This input and output are provided so that two units can be linked together with a common flow center. When either unit has a call for loop outputs, both unit s loop pump relays and variable speed pumps are energized. The flow center then can simply be wired to either unit. The output from one unit should be routed to the input of the other. If daisy chained, up to 16 heat pumps can be wired and linked together in this fashion. Advanced ommunication Ports AXB ommunication ports P6 and P8 will provide future expansion via dedicated protocols. These are for future use. Monitoring Sensors Energy Monitoring Energy Monitoring is standard in all models and includes two current transducers (blower and electric heat) so that the complete power usage of the heat pump can be measured. ompressor power is measured by the variable speed drive. The AID Tool provides configuration detail for the type of blower motor and a line voltage calibration procedure to improve the accuracy. This information can be displayed on the AID Tool, selected communicating thermostats or communicated thru the optional Aurora UP BAS communications board. efrigerant Monitoring efrigerant Monitoring is standard in all models includes two pressure transducers, and three temperature sensors, heating liquid line, suction temperature and existing cooling liquid line (FP1). These sensors allow the measurement of discharge and suction pressures, suction and liquid line temperatures as well as superheat and subcooling. This information can be displayed on the AID Tool or communicated thru the optional Aurora UP BAS communications board. Performance Monitoring (equires Flow Meter) The optional Performance Monitoring includes three temperature sensors, entering and leaving water, leaving air temperature and a water flow rate sensor. Heat of extraction and rejection will be calculated. This requires configuration using the AID Tool for selection of water or antifreeze and is displayed on the AID tool or communicated thru the optional Aurora UP BAS communications board. Modulating Water Valve This output is provided to drive a modulating water valve. Through advanced design the 0-10VD valve can be driven directly from the VS Pump output. The minimum and maximum level are set in the same way as the VS pump using the AID Tool. 50% and 100% are the default settings respectively. 19

ontrols - Aurora Advanced Variable Speed ontrol cont. Special Modes and Applications ommunicating Digital Thermostats The Aurora Advanced VS controls system also requires either the monochromatic or color touch screen graphic display thermostats for user interface. These displays not only feature easy to use graphical interface but display alerts and faults in plain English. Dehumidification Active Active dehumidification will only activate during cooling operation and is based upon the humidity setpoint of the thermostat being at least 5% below the actual relative humidity and being within the temperature parameters described here. The green status LED will flash code 2 when active. The unit can operate a maximum of 2 F below the cooling setpoint. The compressor will ramp up and airflow will begin at a low level. Airflow is then reduced periodically until air coil temperature setpoint is reached. If coil temperature continues to drop, the airflow is increased until air coil setpoint is maintained. After 20 minutes of operation in the Active Dehumidification mode, normal cooling operation will resume for 5 minutes. This cycle continues until the dehumidification setpoint is reached, room temperature is more than 2 F below cooling setpoint, or more than 1 F above cooling setpoint (normal cooling takes over). In IntelliZone2 systems, active dehumidification is only enabled when system is operating on compressor speeds 4 or lower. Once active dehumidification is activated the main zone and any other active cooling zone will remain open. Field Hardware Selectable Options AB Field Selectable Options via Button (SW1) Test/onfiguration Button (See SW1 Operation Table) Test Mode The control is placed in the test mode by holding the push button switch on the AB 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. 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. Variable Speed EM onfiguration Mode The control is placed in the variable speed EM configuration mode by holding the push-button switch SW1 for 5 to 10 seconds, the high, low, and G variable speed EM speeds can be selected by following the LED display lights. LED2 (yellow) will fast flash when entering the variable speed EM 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 variable speed EM 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 variable speed EM configuration mode. Aux blower speed will remain at default or current setting and requires the AID Tool for adjustment. eset onfiguration Mode The control is placed in reset configuration mode by holding the push button switch SW1 on the AB for 50 to 60 seconds. This will reset all configuration settings and the EEPOM 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. AB DIP Switch (SW2) SW2-1 FP1 Selection Low water coil temperature limit setting for freeze detection. On = 30 F; Off = 15 F.

Basic Aurora Safety Features The following safety features are provided to protect the compressor, heat exchangers, wiring and other components from damage caused by operation outside of design conditions. Fuse a 3 amp automotive type plug-in fuse provides protection against short circuit or overload conditions. Anti-Short ycle Protection 4 minute anti-short cycle protection for the compressor. andom Start 5 to 80 second random start upon power up. Fault etry in the fault condition, the control will stage off the outputs and then try again to satisfy the thermostat VS call. Once the thermostat input calls are satisfied, the control will continue on as if no fault occurred. If 3 consecutive faults occur without satisfying the thermostat VS call, then the control will go to Lockout mode. Lockout when locked out, the blower will operate continuously in G blower speed setting. The Alarm output (ALM) and Lockout output (L) will be turned on. The fault type identification display LED1 (ed) shall flash the fault code. To reset lockout conditions with SW2-8 On, the demand call must be removed for at least 30 seconds. To reset lockout conditions with SW2-8 Off, the demand call must be removed for at least 30 seconds. Lockout may also be reset by turning power off for at least 30 seconds or by enabling the emergency shutdown input for at least 30 seconds. AUTION: Frequent cycling of power to the drive can damage the drive! Wait at least 5 minutes between cycles (connecting and disconnecting power to the drive). Lockout With Emergency Heat - if the control is locked out in the heating mode, and a call for emergency heat is received, the control will operate in the emergency heat mode while the compressor is locked out. The first emergency heat output will be energized 10 seconds after the W input is received, and the blower will shift to high speed. If the control remains locked out, and the W input is present, additional stage of emergency heat will stage on after 2 minutes. When the W input is removed, all of the emergency heat outputs will turn off, and the variable speed EM blower will shift to low speed. High Pressure fault is recognized when the Normally losed High Pressure Switch, P4-9/10 opens, no matter how momentarily. The High Pressure Switch is electrically in series with the ompressor ontactor and serves as a hardwired limit switch if an overpressure condition should occur. Low Pressure - fault is recognized when the Normally losed Low Pressure Switch, P4-7/8 is continuously open for 30 seconds. losure of the LPS any time during the 30 second recognition time restarts the 30 second continuous open requirement. A continuously open LPS shall not be recognized during the 2 minute startup bypass time. Loss of harge fault is recognized when the Normally losed Low Pressure Switch, P4-7/8 is open prior to the compressor starting. ondensate Overflow - fault is recognized when the impedance between this line and 24 VA common or chassis ground drops below 100K ohms for 30 seconds continuously. 21

ontrols - Aurora Advanced Variable Speed ontrol cont. Freeze Detection-(oax) - 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. Freeze Detection-(Air oil) - Air oil Freeze Detection will use the FP2 input to protect against ice formation on the air coil. The FP2 input will operate exactly like FP1 except that the set point is 30 degrees and is not field adjustable. Over/Under Voltage Shutdown - An over/under voltage condition exists when the control voltage is outside the range of 18 VA to 30 VA. 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 VA to 30 VA for at least 0.5 seconds, then normal operation is restored. Other Lockouts and Alarms Several other lockouts and alarms are shown in the Status LED1 (LED1, ed) table with the associated codes visible on the thermostat, AB Fault LED, and in text in the AID Tool. Operation Description Power Up - The unit will not operate until all the inputs and safety controls are checked for normal conditions. The unit has a 5 to 80 second random start delay at power up. Then the compressor has a 4 minute anti-short cycle delay after the random start delay. Standby - In standby mode the compressor, pump, and blower motor are not active. The V may be active. The blower and compressor will be off. Heating Operation - The unit will operate based upon demand as calculated by the room setpoint algorithm. The resulting compressor speed (1-12) will also select an appropriate blower speed for the selected compressor speed. Aux Heat will not be available (on IntelliZone2 Aux Heat is available on compressor speeds 10-12) until after the 12th compressor speed has been operational and still is not satisfying the thermostat, then auxiliary electric heat will be activated. 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. ooling Operation - The unit will operate based upon demand as calculated by the room setpoint algorithm. The resulting compressor speed, speeds 1-12, will also select an appropriate blower speed. The blower mode will also have the cooling airflow adjustment applied. In all cooling operations, the reversing valve directly tracks the O input. Thus, anytime the O input is present, the reversing valve will be energized. 22

ontrols - Aurora Advanced Variable Speed ontrol cont. Blower (G) - The blower will start immediately upon receiving a thermostat G command. If there are no other commands from the thermostat the variable speed EM will run on low speed until the G command is removed. egardless of blower input (G) from the thermostat, the blower will remain on low speed for 30 seconds at the end of each heating, cooling, and emergency heat cycle. 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. ontinuous 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. 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. Aurora Advanced VS ontrol LED Displays These three LEDs display the status, configuration, and fault codes for the control. These can also be read in plain English via the Aurora AID Tool. See the LED tables for further explanation. Aurora Interface and Diagnostics (AID) Tool The Aurora Interface and Diagnostics (AID) Tool is a device that is a member of the Aurora network. The AID Tool is used to troubleshoot equipment which uses the Aurora control via Modbus TU communication. The AID Tool provides diagnostics, fault management, variable speed EM setup, and system configuration capabilities to the Aurora family of controls. An AID Tool is recommended, although not required, for variable speed EM airflow settings. The AID Tool simply plugs into the exterior of the cabinet in the AID Tool port.

ontrols - UP DD ontrol (optional) Aurora Touch Interface Aurora UP ontroller ZS Series Sensors The Aurora Unitary Protocol onverter (UP) is designed to add-on to any Aurora based heat pump control. The Aurora Unitary Protocol onvertor (UP) is designed to allow water source heat pumps to be integrated into Building Automation Systems (BAS) with ease. The Aurora UP is an integrated solution and communicates directly with the Aurora Heat Pump ontrols and allows access/control of a variety of internal Aurora heat pump operations such as sensors, relay operation, faults and other information. In turn, the UP then converts internal Aurora Modbus protocol to BAnet MS/TP, LON, or N2 protocols and communicates to the BAS system. This provides the great benefit of complete control integration and a myriad of information available to the BAS from the heat pump control. Plus it also allows individual unit configuration such as EM fan speeds or freeze protection setting directly over the BAS without the need for access to the actual heat pump. The Aurora UP is programmed using the powerful Eikon object oriented. The Aurora UP is implemented with the Aurora Base ontroller (AB) heat pump control into our latest water source heat pumps. This will allow for a BAS to integrate and communicate to the heat pump thru a choice of 3 different communication protocols. The Aurora UP has the ability to communicate BAnet MS/TP, N2 open, or LonWorks (requires LON Plugin card). This flexibility is possible due to the onboard dipswitches which allow for the desired protocol and baud rate to be selected in the field. All zone temperatures and zone sensors are connected to the UP on an Net bus, simplifying hook up at the unit. Net sensors can include a combination of zone temperature and humidity, O2, and VO sensors. The UP includes built-in support for a custom configurable keypad/display unit - BAview6 (4-line by 40 character per line display) or BAview5 (2-line by 16 character per line display). Up to 2 Keypad/display units can be mounted remotely for configuration and troubleshooting. There are an extensive number of points that the UP has available over the network for integration into the BAS. ontrol programmers need to carefully determine which points they want to add into the BAS database. A list of the BAnet points, N2 points, and LON SNVTs are available along with their individual point descriptions by contacting a factory service representative. 26

ontrols - UP DD ontrol (optional) cont. ZS Series Net Sensor Overview The ZS Series line of intelligent zone sensors provides the function and flexibility you need to manage the conditions important to the comfort and productivity of the zone occupants. The ZS sensors are available in a variety of zone sensing combinations to address your application needs. These combinations include temperature, relative humidity, and indoor air quality (carbon dioxide or VOs (Volatile Organic ompounds)). They are built to be flexible allowing for easy customization of what the user/ technician sees. Designed to work with the Aurora UP controllers the ZS sensor line includes the ZS Base, ZS Plus, ZS Pro and ZS Pro-F. The UP uses a proprietary communication called net to receive the space temperature from the zone sensor. This is done using (2) 18 AWG twisted pair unshielded cables for a total of 4 wires connected to the net port. The sensor gets its power from the UP controller and connecting multiple sensors to one UP will allow for space temperature averaging. The UP can support one ZS Pro or ZS Pro F with up to four ZS standard sensors wired to the net port on the UP for a total of 5 zone sensors. The sensors use a precise 10k ohm thermistor with less than 0.18 F drift over a ten year span, this allows for less maintenance or re-calibration after installation. The sensors also have a hidden communication port for connecting a BAview or local laptop that provides access to the equipment for commissioning and maintenance. The table below shows the features of each of the four sensors that are currently available.

Application Notes The losed Loop Heat Pump oncept 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 WaterFurnace Versatec Variable Speed 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: The WaterFurnace 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 WaterFurnace closed source heat pump systems. eturn Water Versatec VS Unit Versatec VS Unit The losed 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. onditions 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. 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 Versatec Variable Speed Approach There are a number of proven choices in the type of Versatec Variable Speed Series system which would be best for any given application. Most often considered are: Vertical - losed Loop/Ground Source Heater/ ejector Versatec VS Unit Versatec VS Unit Versatec VS Unit Versatec VS Unit Pumps Supply Water In the event that a building's net heating and cooling requirements create loop temperature extremes, Versatec Variable Speed 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 WaterFurnace representative has the expertise and computer software to assist in determining optimum system type for specific applications. losed 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 Versatec Variable Speed 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. onversely 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 35

Application Notes cont. the earth. Due to the extended loop temperatures, AHI/ ISO 13256-1 Ground Loop Heat Pumps are required for this application. 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. Plate Heat Exchanger - losed 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. losed 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 - losed Loop/Ground Source losed 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 Versatec Variable Speed systems. A plate frame heal 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 groundsource systems. Due to the extended loop temperatures, AHI/ISO 13256-1 Ground Loop Heat Pumps are required for this application. losed 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. losed Loop/Ground-Source Surface Water Systems also utilize the stable temperatures of Surface Water to maintain proper water source temperatures for Versatec Variable Speed 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, AHI/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./ton of surface area at a minimum depth of 8 feet. WaterFurnace should be contacted when designs for heating dominated structures are required. 36

Application Notes cont. ooler/boiler - losed Loop losed Loop /ooler-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. Due to the moderate loop temperatures, AHI/ISO 13256-1 Water Loop Heat Pumps are required for this application. 37

Water Quality 1. Strainers A. All brazed-plate heat exchangers shall have a strainer within 8 ft of the water/brine inlet. It is highly recommended to use a minimum of 40 mesh in order to provide maximum filtration. In any case, the strainers should never have a mesh size less than 30. B. Failure to install proper stainers and perform regular service can result in serious damage to the unit, and cause degraded performance, reduced operating life and failed compressors. Improper installation of the unit (which includes not having proper strainers to protect the heat exchangers) can also result in voiding the warranty.. Strainers should be selected on the basis of acceptable pressure drop, and not on pipe diameter. The strainers selected should have a pressure drop at the nominal flow rate of the units; low enough to be within the pumping capacity of the pump being used. 2. Water Quality General: Heat pump may be successfully applied in a wide range of commercial and industrial applications. It is the responsibility of the system designer and installing contractor to ensure that acceptable water quality is present and that all applicable codes have been met in these installations. Water Treatment: Do not use untreated or improperly treated water. Equipment damage may occur. The use of improperly treated or untreated water in this equipment may result in scaling, erosion, corrosion, algae or slime. The services of a qualified water treatment specialist should be engaged to determine what treatment, if any, is required. The product warranty specifically excludes liability for corrosion, erosion or deterioration of equipment. The heat exchangers in the units are 316 stainless steel plates with copper brazing. The water piping in the heat exchanger is steel. There may be other materials in the building s piping system that the designer may need to take into consideration when deciding the parameters of the water quality. If an antifreeze or water treatment solution is to be used, the designer should confirm it does not have a detrimental effect on the materials in the system. ontaminated Water: In applications where the water quality cannot be held to prescribed limits, the use of a secondary or intermediate heat exchanger is recommended to separate the unit from the contaminated water. The following table outlines the water quality guidelines for unit heat exchangers. If these conditions are exceeded, a secondary heat exchanger is required. Failure to supply a secondary heat exchanger where needed will result in a warranty exclusion for primary heat exchanger corrosion or failure. WANING: Must have intermediate heat exchanger when used in pool applications. 38

Brine Applications Applications where the leaving fluid temperature goes below 40 F a suitable brine solution must be used. Failure to do so can cause immediate damage to the system. The brine must be approved for use with heat exchangers. Automotive antifreeze solutions are not suitable for use in brazed plate heat exchangers. The freeze detection must be adjusted appropriately for brine applications. The brine solution concentration should be at least 15 F below the lowest leaving fluid temperature.

Installation Notes Typical Unit Installation 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, 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. are 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. Water Piping 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. 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 ports for serviceability. 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. Never use flexible hoses smaller than the inside diameter of the water connection at the unit. Limit hose length to 10 feet per connection. heck carefully for water leaks. 90 deg elbow with vanes on supply Sealed low velocity ductwork Acoustic lining to elbow anvas connector Vibration absorbing pad Flexible water and electrical connections 40

Installation Notes cont. Installing Horizontal Units emove 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. NOTE: Left (ight) eturn Side Discharge can be converted to Left (ight) eturn End Discharge or vice versa, without additional custom sheet metal parts. Horizontal units are normally suspended from a ceiling by six 1/2 in. diameter threaded rods. The rods are usually attached to the unit by hanger bracket kits furnished with each unit. Lay out and install the threaded rods and 1 5/8" strut channel as shown in the Horizontal Dimensional Data. The unit should be pitched approximately 1/4 in. toward the drain in both directions to facilitate the removal of condensate. 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. AUTION: Do not use rods smaller than 1/2 in. diameter since they may not be strong enough to support the unit. The rods must be securely anchored to the ceiling.

Installation Notes cont. Acoustical onsiderations and Equipment Sound Performance Sound Performance The Versatec Variable Speed is third party sound rated in accordance with AI 260. Please consult WaterFurnace Sound Performance Data atalog for details on the AHI standard and sound performance data. ecommendations for Noise eduction Horizontal Unit Location Specify equipment with quietest sound power ratings Do not locate units above areas with a required N 40 or less Space WSHP at least 10 ft (3m) apart to avoid noise summing of multiple units in a space. Maximize the height of the unit above the ceiling (horizontal). Suspend unit with isolation grommets that are appropriately rated to reduce vibrations (horizontal). Vertical Unit Location Specify equipment with quietest sound power ratings Space WSHP at least 10 ft (3m) apart to avoid noise summing of multiple units in a space. Acoustic ceiling coatings can greatly reduce noise levels in mechanical rooms. Mount unit on a sound absorbing pad, extruded polystyrene, rubber or cork pad. Locate return grille 6 ft [1.8 m] from unit 90 deg elbow on supply Sealed low velocity ductwork anvas connector Acoustic lining to elbow 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. Internally line the discharge and return duct within the first 4-8 feet of unit with acoustic insulation. Install an internally lined L shaped return duct elbow at return grille. Face the elbow away from adjacent units. Always install at least one 90 elbow in the discharge duct to eliminate line of sight noise transmission of the blower. Use turning vanes at all elbows and tees to reduce turbulence. Limit supply duct velocities to less than 1,000 fpm Design and install ductwork as stiff as possible Allow 3 duct diameters both up and down stream of the unit before any fittings or transitions are installed. Use duct sealant on all duct joints. Install a short (2-4 ) of flex duct on all branch ducts just prior to discharge boot or diffuser to reduce vibration and duct sound prior to delivery in the room. Locate the branch duct balancing damper as far away from the diffuser as possible. In ceiling plenum systems, install an internally lined L shaped return duct elbow at unit. Face the elbow away from adjacent units (horizontal). Turning vanes at elbows and Tees Locate units over hallways where possible Branch damper upstream Flex duct at diffuser 2-4 ft.

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 factory representative. While a computer software program 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. 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. 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. ooling 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 WATE OIL INSULATION OPTION SHOULD BE SELETED WHEN ENTEING WATE TEMPEATUES AE EXPETED TO BE BELOW 45-50 F. Geothermal Selection Example Step 1: Determine the actual heating and cooling loads at the desired dry bulb and wet bulb conditions. Step 2: Obtain the following design parameters: Entering water temperature, water flow rate in gpm, airflow in cfm, water flow pressure drop and design wet and dry bulb temperatures. Airflow, 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. Step 4: Enter tables at the design water flow and water temperature. ead the total and sensible cooling capacities (NOTE: interpolation is permissible, extrapolation is not). Step 5: ead the heating capacity. If it exceeds the design criteria it is acceptable. It is quite normal for water source heat pumps to 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. orrected Total ooling = tabulated total cooling x wet bulb correction. orrected Sensible ooling = tabulated sensible cooling x wet/dry bulb correction. Step 7: ompare 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. 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 airflow 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. emember, when in doubt, undersize slightly for best performance. Example Equipment Selection - ooling 1. Load Determination: Assume we have determined that the appropriate cooling load at the desired dry bulb 80 o F and wet bulb 65 o F conditions is as follows: Total ooling...135,000 Btu/hr Sensible ooling... 87,000 Btu/hr Entering Air temperature...75 o F Dry Bulb/ 65 o F Wet Bulb 2. Design onditions: Similarly, we have also obtained the following design parameters: Entering Water Temperature... 90 o F Water Flow (Based upon 10 o F rise in temperature)...34.0 gpm Airflow equired... 4,200 cfm @ 0.5 in. wg. 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. 53

Selection Example cont. 3, 4, & 5. HP Selection: After making our preliminary selection (*180) we enter the tables at design water flow and water temperature and read Total ooling, Sens ooling and Heat of ej. capacities: Total ooing...165,000 Btu/hr Sensible ooling...129,300 Btu/hr Heat of ejection...227,300 Btu/hr 6 & 7. Entering ooling apacity and Airflow orrections: Next, we determine our correction factors. (efer to ooling apacity, and Airflow orrection Tables 4,200/5,600 nom. = 75% as percent of nominal) orrected Total ooling = 165,000 x.967 x.835 = 133,228 orrected Sensible ooling = 129,300 x.881 x.764 = 87,030 orrected Heat of ejection = 227,300.972 x.789 = 174,318 8. Water Temperature ise alculation & Assessment: H = 500 x gpm x (T in - T out ) H = (T in - T out ) or T ise 500 x gpm 174,318 72,432 = 9.65 10.3 F ise 500 x 34 15 Note: 500 = parameters for water & 485 = parameters for antifreeze solutions to 30% weight. When we compare the orrected Total ooling and orrected Sensible ooling figures with our load requirements stated in Step 1, we discover that our selection is within + 10% of our sensible load requirement. Furthermore, we see that our orrected Total cooling figure is within 2,000 Btu/hr of the actual indicated load. Antifreeze orrections atalog performance can be corrected for antifreeze use.

Determine the corrected full load heating and cooling performance at 30 F and 90 F respectively as well as pressure drop at 30 F for a *120 model. The corrected cooling capacity at 90 F would be: 126,800 Btu/h x 0.969 = 122,869 Btu/h The corrected heat capacity at 30 F would be: 104,700 Btu/h x 0.913 = 95,591 Btu/h The corrected pressure drop at 30 F and 30gpm would be: 1.26 ft. hd. x 1.270 = 1.60 ft. hd. 54
