LONWORKS net-works are supported with an external Controls Unitary ProductsOperation OverviewThe Simplicity SE Controls offer a new control architecturedesigned to provide basic equipment protection, and simplethermostat control options, as well as advanced DDC controland diagnostic algorithms. This modular architecture offeringhelps control the costs that are associated with field installa-tions. Programmed, factory-mounted Controls eliminate theneed for field , the DDC Controls and diagnostics offer the nec-essary startup and commissioning automation to furtherdecrease installation costs while improving energy efficiencyover the life of the installation. This fully implemented solutionaligns with the product road maps for Building AutomationSystems (BAS), HVAC, and refrigeration to not only deliver abuy blue product, but also to ensure we deliver a fully opti-mized solution to the SE is fully compatible with Metasys software andits associated components.

4 The equipment behaves similarto other Metasys network controllers, such as the FieldEquipment Controller (FEC), so it is easily integrated intoyour network. The factory-programmed Simplicity SE isdesigned for all 3-40 Ton packaged products and TonSplit System products. To ensure controller support for thewide range of RTUs, we developed a super application thatconsists of all available parameters within one an installation perspective, no programming is unit is configured at the factory based on the order. Youcan modify the unit in the field with either the controller s localdisplay or Mobile Access Portal (MAP) SE Local DisplayThe Simplicity SE local display provides a simple and localinterface that lets mechanical contractors operate the equip-ment without additional tools, software, or computers. All con-figuration settings are accessible through the local LCD, andyou can modify them for the specific application requirements(Figure 2).

All safety circuitsare wired to the UCB for equipment protection. The UCBdesign and core asset foundation are based on the Metasyssystem FEC controller platform. The local display on the UCBis the main UI that lets you configure, self test, view localinformation, and control the UCB offers a new USB drive feature that provides valu-able access to history and trends that you can later view onany USB port allows provisioning of the main controller soft-ware and pushes updates to all networked controllers on theSA Bus network.

The new economizer controller replaces theexisting third-party economizer economizer controller communicates via standard SAbus to the main controller of the RTU, the UCB.)

8 When theeconomizer is installed as a field option, the controller is fac-tory mounted with a wiring harness that is necessary for con-nection. Once connected, the economizer controller receivespower and communication from the UCB. No additional pro-gramming is required in the UCB self-discovers the Economizer controller. After self-discovery, the Economizer application executes based on thefactory default settings. Use the local display to make anyconfiguration changes. You can also accomplish this usingthe Mobile Access Portal (MAP) economizer control meets Title 24 Standards. The econ-omizer has the ability to report up to five dedicated FaultDetection Diagnostics (FDD) through the local LCD, networksensor, thermostat with the X output for faults, or MAP Gate-way. In cases of equipment integration into a BMS, the samefaults are communicated via the standard communicationprotocols.

9 The FDDcontroller lets the package equipment predict faults beforethey become a major failure, cause comfort issues, or resultin efficiency problems. The FDD controller is one of the keycomponents of the algorithms continuously run within the FDD con-troller. The algorithms monitor the types of inputs to preciselyindicate the faults and recommend how to correct them.

Check damper, linkage to actua-tor, or the economizer is allowing excess outdoor air Controls Unitary ProductsFDD controller meets all of the pending California EnergyCode Regulations (Title 24).

10 During the startup process, the FDD controller calculates theefficiency and capacity of the equipment and generates abaseline for future measurements. The algorithms providethis type of information during the equipment life cycle. Youcan view this information from the UCB local display, MAP, orthrough a BMS connection. These two calculated values, effi-ciency and capacity, enable you to make smart decisionsregarding your equipment . You can quickly and easily seewhen the equipment is not performing to the startup and com-missioning efficiency 3 shows all the refrigeration circuit Efficiency index and Capacity index are added featuresfrom the FDD controller. You can use the indexes for theentire suite of the Packaged ControllerFIGURE 9 : Four-Stage Controller SE-SPU1004-0 (031-03032-000A / 1034521)The four-stage controller of the Simplicity SE family enables25-40 ton of packaged equipment for two additional stages ofcooling and one additional stage of heating.
