Control Features MicroTech III Unit Controller The MicroTech III Unit Controller is a microprocessorbased control board conveniently located in the unit control box for easy access through a removable access panel. The standalone unit controller is a hard wired interface and provides all the necessary field connections. The board can be wired for 24volt AC output to the wall thermostat by using terminals R & C. An LED annunciator is located on the front corner of the unit chassis to quickly check the operating status of the unit. MicroTech III Operating Features Assumes cycle fan operationnot continuous fan operation: Startup The unit will not operate until all the inputs and safety controls are checked for normal conditions. Cooling mode On a call for cooling, the compressor and fan will start 0 to 30 seconds later. When the load is satisfied, the compressor and fan shut off. Heating Mode On a call for heating, the reversing valve is energized after seconds and the compressor and fan start. When the load is satisfied, the compressor and fan shut off. The reversing valve is deenergized seconds later. Short Cycle Protection & Random Start Each time the compressor stops, a new random compressor startdelay time between 1 and 240 seconds is generated. This prevents compressor short cycling and prevents units from starting simultaneously after coming back from an unoccupied cycle. Unoccupied Mode A simple grounded signal between terminals U and C (no power source required), puts the unit into the unoccupied mode for night setback operation. Override Mode A switch on the deluxe automatic changeover thermostat can be activated during the unoccupied mode to put the unit back into the occupied mode for two hours for afterhours heating or cooling. Motorized Valve/Pump Restart The IV/PR (H8) terminals on the The MicroTech III unit controller are used to energize (open) a motorized valve or start a water pump to get water circulating prior to starting the compressor on call for heating or cooling. The IV/ PR (H8) terminal may be daisy chained between 200 units. Brownout Protection The MicroTech III unit controller measures the input voltage and will suspend compressor and fan operation if the voltage falls below % of the unit nameplate rated value. A unique LED status is generated and an output is available to a fault LED at the thermostat. Unit Shutdown A simple grounded signal puts the unit into the shutdown mode. Compressor and fan operations are suspended. A unique LED status is generated and an output signal is made available for connection to a fault LED at the thermostat. Condensate Overflow Protection The MicroTech III unit controller incorporates a liquid sensor at the top of the drain pan. Upon sensing water flow, cooling operation is suspended. A unique LED status is generated and output is available to a fault LED at the thermostat. Heating operation is not suspended. Remote Reset of Automatic Lockouts The Remote Reset feature provides the means to remotely reset automatic lockouts generated by highpressure and/or lowtemperature faults. When the MicroTech III unit controller is in automatic lockout due to one of these faults, and the cause of the fault condition has been alleviated, energizing the Oterminal for 10 seconds or more will force the control board to clear the lockout. A unit power cycle can also be used to clear an automatic lockout if the conditions causing the fault have been alleviated. Intelligent Reset The Fault Retry feature helps to minimize nuisance trips of automatic lockouts caused by highpressure and/or lowtemperature faults. This feature clears faults the first two times they occur within a 24hour period and triggers an automatic lockout on the 3rd fault. The retry count is reset to zero every 24 hours. Equipment Protection Control The MicroTech III unit controller receives separate input signals from the refrigerant highpressure switch and the low suction line temperature sensor. In a highpressure situation, compressor operation is suspended. In a low temperature situation, the unit goes into a defrost cycle where the unit is put into cooling operation for seconds until the coaxial heat exchanger is free of ice. Each switch generates its own unique LED status and output is available to a fault LED at the thermostat if either situation exists. Note: Most unit fault conditions are the result of operating the equipment outside the unit specifications.

Applications Typical Cooling and Heating Refrigeration Cycles (For standard heat pump operation only) Figure 14: Cooling Refrigeration Cycle When the wall thermostat calls for COOLING, the reversing valve directs the flow of the refrigerant, a hot gas, from the compressor to the watertorefrigerant heat exchanger. There, the heat is removed by the water, and the hot gas condenses to become a liquid. The liquid then flows through a thermal expansion valve to the airtorefrigerant heat exchanger coil. The liquid then evaporates and becomes a gas, at the same time absorbing heat and cooling the air passing over the surfaces of the coil. The refrigerant then flows as a low pressure gas through the reversing valve and back to the suction side of the compressor to complete the cycle.

Applications Systems Water source heat pump systems are one of the most efficient, environmentally friendly systems available for heating and cooling buildings. Highefficiency, self contained units (sizes 7,000 btuh to 420,000 btuh) can be placed in virtually any location within a building. Each unit responds only to the heating or cooling load of the individual zone it serves. This permits an excellent comfort level for occupants, better control of energy use for building owners and lower seasonal operating costs. The AirConditioning Refrigeration Institute (ARI) and the International Standards Organization (ISO) publish standards so that water source heat pumps are rated for specific applications. The ARI/ISO loop options shown in this catalog are typical water source heat pump loop choices available in today s market. These systems offer benefits ranging from low cost installation to the highest energy efficiency available in the market today. Boiler / Tower Applications: ARI 320 / ISO 132561 A Boiler/Tower application uses a simple twopipe water circulating system that adds heat, removes heat or transfers rejected heat to other units throughout the building. The water temperature for heating is generally maintained between 65ºF ºF and is usually provided by a natural gas or electric boiler located in a mechanical room. The condensing water temperature, during cooling months, is maintained between 85ºF and 95ºF and requires the use of a cooling tower to dissipate waste heat. Cooling towers can be located on the roof, or inside or adjacent to the building. This application can be the lowest cost of the loop options available. Note: ASHRAE 90.1 standards require that circulating pumps over 10 HP will require use of variable frequency drive equipment and pipe insulation to be used whenever water temperatures are below degrees and above 105 degrees. See ASHRAE 90.1 Standards for details. Figure 16: Boiler/Tower Application Open Loop Well Water Applications: ARI 325 / ISO 132561 Open Loop well water systems use ground water to remove or add heat to the interior water loop. The key benefit of an open loop system is the constant water temperature, usually ºF to ºF, which provides efficient operation at a low first cost. Most commercial designers incorporate a heat exchanger to isolate the building loop from the well water. Using heat exchangers can reduce maintenance issues while still allowing the transfer of heat from unit to unit as with the Boiler/Tower System. A successful design provides an ample amount of groundwater (approximately 2 GPM per ton) and adequate provisions for discharging water back to the aquifer or surface. Open Loop applications are commonly used in coastal areas where soil characteristics allow reinjection wells to return the water back to the aquifer. Note that some states have requirements on the depths of return water reinjection wells, and such wells must be approved by the United States Environmental Protection Agency. Also, bad water quality can increase problems with heat exchanger scaling. Suspended solids can erode the heat exchanger. Strainers can be used to contain suspended solids. Figure 17: Open Loop Well Application Page 16 of McQuay Enfinity Water Source Heat Pumps Catalog 11033

Applications Closed Loop Geothermal Applications ARI 330/ ISO 132561 Vertical Closed Loop applications are installed by drilling vertical bore holes into the earth and inserting a plastic polyethylene supply/return pipe into the holes. The vertical wells are connected in parallel reverse return fashion to allow the water from the building to circulate evenly throughout the borefield. The circulating fluid dissipates heat to the ground in a similar manner as a tower and adds heat back to the loop like a boiler. If properly designed, the loop field can maintain the loop temperatures necessary to condition the building without the use of a boiler or a tower. Loop temperatures usually range from 37ºF to 95ºF in Northern climates. Southern applications can see temperatures ranging from 40ºF to 100ºF. The number of bore holes and their depth should be determined by using commercial software that is specifically designed for vertical geothermal applications. Typical bore depths of a vertical loop range from 1 to 400 feet and generally require about 2 feet of surface area per ton of cooling. Figure 18: Vertical Loop Application Figure 19: Horizontal Loop Application A Surface Water or Lake closed loop system is a geothermal loop that is directly installed in a lake or body of water that is near the building. In many cases, the body of water is constructed on the building site to meet drainage or aesthetic requirements. Surface loops use bundled polyethylene coils that are connected in the same manner as a vertical or horizontal loop using a parallel reverse return design. The size and the depth of the lake is critical. Commercial design services should be used to certify that a given body of water is sufficient to withstand the building loads. Loop temperatures usually range from 35ºF to 90ºF and prove to be the best cooling performer and lowest cost loop option of the three geothermal loops. Some applications may not be good candidates due to public access or debris problems from flooding. Figure 20: Surface Water Loop Application A closed loop Horizontal geothermal application is similar to a vertical loop application with the exception that the loops are installed in trenches approximately 5 feet below the ground surface. The piping may be installed using a fourpipe or sixpipe design and could require 1,0 to 2,000 square feet of surface area per ton of cooling. Loop temperatures for a commercial application can range from 35ºF to 95ºF in Northern climates. Southern climates can see temperatures ranging from 40ºF to 100ºF. Horizontal loops are generally not applied in urban areas because land use and costs can be prohibitive. New advances in installation procedures have improved the assembly time of horizontal loops while keeping the first cost lower than a vertical loop.

Applications Application Considerations Unit Location The VFC, VFW water source heat pump can be installed free standing in an equipment room; however, closet installations are more common for the small vertical type units. Generally, the unit is located in the corner of a closet with the nonducted return air facing 90º to the door and the major access panels facing the door as shown in the illustration at right. Alternatively, the unit can have a ducted return air with the opening facing the door and the major access panels facing 90º to the door. Locate a vertical unit to allow for easy removal of the filter and access panels. Allow a minimum of 18" (46 cm) clearance on each side of the unit for service and maintenance access. Always be sure to leave at least one side of the filter rack unobstructed so that the service personnel will be able to slide the filter out. Install a field supplied line voltage disconnect for branch circuit protection. To reduce noise emissions, install a fieldprovided 1/2 inch thick, isolator pad below the entire base of the vertical unit. The pad should be equal to the overall footprint size of the unit to provide sound dampening of the unit while in operation.

Applications Ductwork and Attenuation All ductwork should conform to industry standards of good practice as described in ASHRAE Systems Guide. The discharge duct system will normally consist of a flexible connector at the unit, a noninsulated transition piece to the full duct size, a short run of duct, an elbow without vanes, and a trunk duct teeing into a branch circuit with discharge diffusers as illustrated below. Return air ducts can be brought in through a wall grille and then to the unit. The return duct system will normally consist of a flexible connector at the unit and a trunk duct to the return air grille. With metal duct material, the return air duct should be internally lined with acoustic insulation for sound attenuation. Return air ductwork to the unit requires the optional return air duct collar/2" (51mm) filter rack kit.

These flexible hoses reduce vibration between the unit and the rigid piping system. Figure 24: Fire Rated Supply or Return Hoses Heat Pump Piping The water source heat pump unit is typically connected to the supply / return piping using a reverse return piping system which includes a flow control device so that flow requirements are met for each zone. A short, high pressure flexible hose is used to connect the unit to the building s hard piping and acts as a sound attenuator for both the unit operating noise and hydronic pumping noise. One end of the hose has a swivel fitting to facilitate removal of the unit for replacement or service. Include supply and return shutoff valves in the design to allow removal of a unit without the need to shut down the entire heat pump system. The return valve may be used for balancing and will typically have a memory stop so that it can be reopened to the proper position for the flow required. Fixed flow devices are commercially available and can be installed to eliminate Condensate Drain The factory provided condensate drain trap on the vertical unit is located inside the cabinet. Condensate removal piping must be pitched away from the unit not less than 1/4" per foot. A vent is required after the trap so that the condensate will drain away from the unit. The vent can also act as a clean out if the trap becomes clogged. To avoid having waste gases entering the building, the condensate drain should not be directly piped to a drain/waste/vent stack. See local codes for the correct application of condensate piping to drains. Catalog 11033 McQuay Enfinity Water Source Heat Pumps Page 19 of

Applications Unit Selection Achieving optimal performance with water source heat pump systems requires both accurate system design and proper equipment selection. Use a building load program to determine the heating and cooling loads of each zone prior to making equipment selections. With this information, the McQuay SelectTools software selection program for Water Source Heat Pumps can be used to provide fast, accurate and complete selections of all McQuay water source heat pump products. SelectTools software is available by contacting your local McQuay Representative. While we recommend that you use McQuay SelectTools software for all unit selections, manual selections can be accomplished using the same zone load information and the capacity tables available in this catalog. Boiler / Tower Application Manual Selections: The following example illustrates a typical selection for a zone in a boiler/tower system for a commercial building. A building load program determines that this zone needs 38,255 BTUH of total cooling, 31,832 BTUH of sensible cooling and 36,988 BTUH of total heating. The water temperatures for the boiler/tower system are 90ºF for cooling and ºF for heating. The return air temperature is ºF dry bulb with 67ºF wet bulb for cooling and ºF for heating. Zone requirements: Total Cooling Load = 38,255 BTUH Sensible Cooling Load = 31,832 BTUH Total Heating Load = 36,988 BTUH Air Flow Required = 1510 CFM Return Air Cooling = ºFDB/ 67ºFWB Return Air Heating = ºFDB Since a McQuay Model VFC 036 produces approximately 36,000 BTUH of cooling, it is not sufficient for this zone and a model VFC 042 should be considered. Model VFC is chosen because it is specifically designed for a boiler/ tower application. Typical water flow rates for boiler/tower applications are 2.0 to 2.5 GPM per ton and in this example no antifreeze is used. Selection: Model...VFC 042 (Boiler / Tower model) Total Cooling Capacity @ 90 EWT = 40,816 BTUH Sensible cooling capacity @ 90 EWT = 32,4 BTUH Total Heating Capacity @ EWT = 52,019 BTUH CFM = 1510 @.5 ESP (Wet Coil) Water Flow required to meet capacity = 8 GPM Water Pressure drop = 6.9 (FT. H2O) Final Selection...VFC 042 Geothermal Applications: The following example illustrates the same zone in a geothermal application. The load requirements for the zone are the same as the above example 38,255 BTUH of total cooling and 31,832 BTUH of sensible cooling and 36,988 BTUH of heating. Geothermal loop software programs are available to help determine the size of the loop field based on: Desired entering water temperatures for the system. Specific acreage available for the loop which produces specific min./max loop temps for the unit selection. Entering water temperatures for geothermal systems can be as high as 90º to 100ºF and as low as 30ºF based on the geographical location of the building. Water flow rates are typically 2.5 to 3 GPM per ton and the use of antifreeze is required in most northern applications. Zone requirements: Total Cooling Load = 38,255 BTUH Sensible Cooling Load = 31,832 BTUH Total Heating Load = 36,988 BTUH Air Flow Required = 1510 CFM Return Air Cooling = DB / 67 WB Return Air Heating = DB A McQuay Model VFW is chosen for this geothermal application. Model VFW offers insulated water piping for condensation considerations and a different freezestat setting to allow entering water temperatures lower than 40ºF (with antifreeze). Output capacities should be recalculated using the antifreeze reduction tables that are shown on page 49. The Model VFW 042 is first considered but may not meet the heating load because of the reduced entering water temperatures (35ºF) and an antifreeze solution of 21 % propylene (see page 47). Selection: Model...VFW 042 (Geothermal model) Total cooling capacity @ 100 EWT = 40,434 BTUH x.9 = 39,625 Sensible cooling capacity @ 100 EWT = 32,164 BTUH x.9 = 31,520 Total heating capacity @ 35 EWT = 38,335 BTUH x.975 = 37,377 CFM = 1510 @.6 ESP (Dry Coil) Water Flow required to meet capacity = 10.8 GPM Water Pressure drop = 12.7 x 1.5 = 14.61 (FT. H2O) Final Selection...VFW 042 Notes: In applications where the zone may be a corner office or have excessive glass area, the heating load could be greater than the heating output capacity of the VFW 042 model (say 41,985 BTUH). The choices are to upsize the unit to the next model available (048), or add an electric duct heater to supplement the output of the 042 unit.

Sheltered locations such as attics, garages, etc., generally will not provide sufficient protection against extremes in temperature and/or humidity, and equipment performance, reliability, and service life may be adversely affected. Power supply A voltage variation of +/10% of nameplate voltage is acceptable. Threephase system imbalance shall not exceed 2%. Additional information for initial startup only Standard range units: Units are designed to start in an ambient of ºF (10ºC), with entering air at ºF (10ºC), with entering water at ºF (21ºC), with both air and water at the flow rates used in the ISO 132561 rating test, for initial startup in winter. Note: This is not a normal or continuous operating condition. It is assumed that such a startup is for the purpose of bringing the building space up to occupancy temperature. Geothermal range units: Geothermal range heat pump conditioners are designed to start in an ambient of 40ºF (5ºC), with entering air at 40ºF (5ºC), with entering water at 40ºF (5ºC), with both air and water at the flow rates used in the ISO 132561 rating test, for initial startup in winter. Note: This is not a normal or continuous operating condition. It is assumed that such a startup is for the purpose of bringing the building space up to occupancy temperature. Notes: 1 At ARI flow rate 2 Maximum and minimum values may not be combined. If one value is at maximum or minimum, the other two conditions may not exceed the normal condition for standard units. Extended range units may combine any two maximum conditions, but not more than two, with all other conditions being normal conditions.
