Controls Unit Control MicroTech III SmartSourcee Unit Control & I/O Expansion Module Built-in Diagnostics The MicroTech III SmartSource Controller is a microprocessor-based control board in combination with an I/O Expansion Module for extra functionality. The control box is accessible through the left or right end corner panel on horizontal units and through the bottom-front access panel on the vertical unit.
Controls Operating Modes ■ 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, the fan will energize at its “fan only” setting, the pump request will engergize, the 45 second flow timer will start after the flow, compressor minimum off, and random startup timers are expired, the compressor and fan will start at the stage 1 cooling settings.
Controls ■ Boilerless Electric Heat Mode – When the entering water temperature is below setpoint, the compressor will not be allowed to operate. On a call for heating, stage 1 electric heat will be energized and the fan will start at its electric heat setting. For units equipped with 2 stages of electric heat, if room setpoint conditions are not satisfied, the second stage of electric heat will be energized and the fan will continue to operate at its electric heat setting.
Controls Unit Protections & LED Fault Status Annunciation Refrigerant Circuit High Pressure Protection A normally closed high (compressor discharge) pressure switch is used in SmartSource units to help protect the refrigerant circuit from excessively high pressure. The controller will monitor this switch. Note: Due to the method of sensing the HP switch, the true state cannot be determined unless the compressor output is active.
Controls Remote Reset of Automatic Lockouts The Remote Reset feature provides the means to remotely reset automatic lockouts. There are (3) means to reset an automatic lockout condition: • Using the thermostat create 2 demands for capacity within 30 seconds.

Applications Typical Vertical Installation Unit Location SmartSource vertical water source heat pumps 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 non-ducted return air facing 90º to the door and the major access panels facing the door as shown in Figure 13.
Applications Typical Horizontal Installation Unit Location It is important to leave enough space for service personnel to perform maintenance or repair. Locate the horizontal 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 and do not install the unit above any piping.

Applications 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.
Applications Water System Quality The cleaning, flushing and chemical treatment of a water source heat pump system is fundamental to efficient operation and the life expectancy of the system. Potential system problems produced by the use of water fall into three general categories: 1. Scale formation – Mineral deposits which result from the crystallization and precipitation of dissolved salts in the water.
Applications Condensate Drain Improper trapping can lead to several problems. If the trap is too tall, negative pressure will prevent drainage, causing condensate backup. If the trap is too short the seal will be destroyed or nonexistent, producing the same effect as a non-trapped system. Construct the trap of 7/8" clear plastic piping. The condensate piping from the drain trap must be sloped to facilitate proper drainage. The clear plastic trap should be clamped and removable for cleaning.
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 Daikin McQuay SelectTools™ software selection program for Water Source Heat Pumps can be used to provide fast, accurate and complete selections of all water source heat pump products.
Applications Zone Requirement: Total Cooling Zone = 41,099 BTUH Sensible Cooling Zone = 30,327 BTUH Heating Zone = 37,758 BTUH Design Air Flow = 1,200 CFM Return air – Cooling = 80°F DB/67°F WB Return air – Heating = 70°F Entering Fluid Temperature Cooling = 100°F – 20% P.G. Entering Fluid Temperature Heating = 45°F – 20% P.G. A Model GT *044 is chosen for this geothermal application.
Applications When selecting an appropriate SmartSource loop pump, the working fluid (water plus antifreeze), total head loss and flow must be known. The following represents the typical total head loss calculation for a decentralized geothermal loop pump application: ■ Using nominal 2-ton vertical unit W.GTV.1.026 ■ Fluid – 15% Methanol Solution in Water ■ Design EWT Heating - 35°F (Maximum pressure drop occurs with high density fluid.
