8 Control Features MicroTech III Controller The MicroTech III Controller is a microprocessor-based 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 24-volt AC output to the wall thermostat by using terminals R & C. An LED annunciator is located on the front of the unit chassis to allow quick check of the unit operating status. MicroTech III Operating Features Assumes cycle fan operation-not continuous fan operation: Start-up The unit will not operate until all the inputs and safety controls are checked for normal conditions. Cooling mode On a call for cooling from the wall thermostat, the controller will energize the fan relay and stage compressors to satisfy the space temperature setpoint. When the load is satisfied, the controller will disable the compressor and fan. Heating Mode On a call for heating from the wall thermostat, the controller will enable the fan, energize circuit one reversing valve and circuit 1 compressor to satisfy the space heating setpoint. If the space temperature setpoint is not satisfield, circuit two reversing valve and circuit 2 compressor will be energized and run until the heating setpoint at the thermostat is satisfied. Random Start Power-up Delay Timer In the event of a building power outage, this feature prevents multiple units from starting simultaneously upon building power restoration. 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. Interstaging Timer A default value of 5 minutes between staging of compressors, this feature minimizes short cycling of compressors and improves comfort. 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 after-hours 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 a maximum of 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. 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. Condensate Overflow Protection The MicroTech III 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. Remote Reset of Automatic Lockouts The Remote Reset feature provides the means to remotely reset automatic lockouts generated by high-pressure and/ or low-temperature faults. When the MicroTech III controller is in automatic lockout due to one of these faults, and the cause of the fault condition has been alleviated, energizing the O-terminal 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 high-pressure and/or low-temperature faults. This feature clears faults the first two times they occur within a 24-hour 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 controller receives separate input signals from the refrigerant high-pressure switch and the low suction line temperature sensor. In a high-pressure 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. Page 8 of 56 Daikin Large Vertical Water Source Heat Pumps Catalog

11 Applications Unit Location Large Vertical Water Source Heat Pump units are easily located in equipment rooms or floor-by-floor installations. They can be applied to all building types where it is advantageous to extend the water source heat pump concept to larger or core areas. Locate the unit in an area that allows for easy removal of the filter and access panels, and has enough space for service personnel to perform maintenance or repair. Provide sufficient room to make water, electrical and duct connections. The main control panel is located in the center front of the unit. The fan discharge is top front, and the fan motor is always located at the piping end. Unit sides opposite the control panel and opposite the piping side may be up against walls and still allow for service and maintenance through the remaining access panels. Figure 5: Fan Deck Arrangements Figure 4: Service Clearances Side B Fan Motor Side A 24" (610 mm) Piping Location 24" (610 mm) Control Box Location The contractor should make sure that access has been provided including clearance for 2" (51 mm) thick filter brackets, duct collars and fittings at water and electrical connections. Allow adequate room around the unit for a condensate trap. The unit can be installed free standing in an equipment room. Generally, the unit is located in a separate room with the non-ducted return air facing the return air intake. Alternatively, the unit can have a ducted return air. It is recommended that the unit be located on vibration isolators to reduce any vibration (see Figure 6 on page 12). Rear (or Top) Discharge Right-Hand Piping (Upblast-Rear) Front (or Top) Discharge Right-Hand Piping (Upblast-Front) Fan Motor Front (or Top) Discharge Left-Hand Piping (Upblast-Front) IMPORTANT 1. A 24" (610 mm) minimum clearance is required on the return air, control box and piping sides. However, a 36" (914 mm) clearance allows for easier serviceability. 2. A 12" (305 mm) minimum clearance is required on Side A to gain access to panel to remove locking collar for shaft removal. 3. A 6" (152 mm) clearance is required on Side B to remove screws holding top panel. 4. Top clearance is required for fan shaft removal. 5. Some codes dictate a " (1524 mm) clearance above the control box which could be violated with a ducted return. Check your local codes. Fan Deck Arrangements Six fan discharge arrangements and two piping arrangements are available. With the return air side defined as the front of the unit, the water piping connections may be right-hand (side) or left-hand. All units have a single supply and return water connection with a copper FPT type fitting that protrudes through the unit casing for easy connection. The condensate connection is also a copper FPT type and is located on both sides of the unit. The unused connection is plugged. Rear (or Top) Discharge Left-Hand Piping (Upblast & Rear) Straight Horizontal Discharge Left-Hand Piping (Top-Horizontal Discharge) Straight Horizontal Discharge Right-Hand Piping (Top-Horizontal Discharge) Notes: 1. The hand of unit is determined by looking at the return air (filter) side. The piping and electrical connections are always made on the hand side of the unit. The return air (filter) side is considered the front of the unit. 2. The fan motor is always located at the piping/ electrical connection (hand) side of the unit.

13 Applications Ductwork and Attenuation Discharge ductwork is normally used with these conditioners. Return air ductwork may also be required but will require field installation of a return air duct collar. 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, a transition piece to the final duct size, a short run of duct, an elbow without vanes and a trunk duct tee d into branch ducts with discharge diffusers. Transformation duct must not have angles totalling more than 30 degrees or severe loss of air performance can result. All units have multiple fan outlets. The preferred method for minimum static pressure loss would be individual ducts at each outlet connected to a larger main duct downstream (Figure 9). For minimum noise transmission, the metal duct material should be internally lined with acoustic fibrous insulation. The ductwork should be laid out so that there is no line of sight between the conditioner discharge and the distribution diffusers. Return air ducts can be brought in adjacent to the return air of the conditioner. Typically, the equipment room becomes the common return air plenum. Do not insert sheetmetal screws directly into the unit cabinet for connection of supply or return air ductwork, especially return air ductwork which can hit the drain pan or the air coil. Notes: 1. Transformations to supply duct have maximum slope of 1" to 7". 2. Square elbows with double thickness vanes may be substituted. 3. Do not install ducts so that the air flow is counter to fan rotation. If necessary, turn fan deck assembly and motor. 4. Transformations and units shall be adequately supported so no weight is on the flexible connection.

14 Applications Typical Cooling and Heating Refrigeration Cycles Dual Compressors Note: Typical temperature readings are at full load conditions at ISO for boiler-tower applications. Figure 10: Cooling Refrigeration Cycle When the wall thermostat calls for COOLING, the reversing valve (de-energized) directs the flow of the refrigerant, a hot gas, from the compressor to the water-to-refrigerant heat exchanger (coaxial 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 air-to-refrigerant heat exchanger coil (evaporator). 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. Figure 11: Heating Refrigeration Cycle When the wall thermostat calls for HEATING, the reversing valve (energized) directs the flow of the refrigerant, a hot gas, from the compressor to the air-to-refrigerant heat exchanger coil (condenser). There, the heat is removed by the air passing over the surfaces of the coil and the hot gas condenses and becomes a liquid. The liquid then flows through a thermal expansion valve to the water-to-refrigerant heat exchanger (evaporator). The liquid then evaporates and becomes a gas, at the same time absorbing heat and cooling the water. 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.

15 Applications Systems Water source heat pump systems are one of the most efficient, environmentally friendly systems available for heating and cooling buildings. High-efficiency, self contained units (sizes 7,000 btuh to 290,000 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 Air-Conditioning 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 A Boiler/Tower application uses a simple two-pipe 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 ºF 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 12: Boiler/Tower Application Open Loop Well Water Applications: ARI 325 / ISO 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 50ºF 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.

16 Applications Closed Loop Geothermal Applications: ARI 330/ISO 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 150 to 400 feet and generally require about 250 feet of surface area per ton of cooling. Figure 14: Vertical Loop Application Figure 15: 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 16: 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 four-pipe or six-pipe design and could require 1,500 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.
