OVERVIEWSystem FeaturesOverviewFeaturesThe DDC Controller (WattMaster Part No. OE337-26B-00001;Daikin Part No. PCBCG100) is designed with 8 analog inputs, 4analog outputs, 8 binary inputs, and 8 relay outputs.The DDC Controller provides the following:The DDC Controller has an on-board BACnet port for connectionto a BACnet MS/TP network.The DDC Controller contains a 2 x 8 LCD character displayand 4 buttons that allow for status and alarm display, setpointconfiguration, and BACnet configuration.There are also 2 E-BUS Expansion Ports which allow the connectionof communicating sensors and future E-BUS Modules via modularcable assemblies. In addition, there is a USB port which is used forconnection to a computer running PrismD software.The DDC Controller has an on-board CommLink that providesfor stand-alone programming and monitoring via a direct USBconnection to a computer running PrismD software. If used on anetworked system that has an external CommLink, this on-boardCommLink would not be used. Alternatively, the System ManagerTouch Screen II for DDC (OE392-10-G) can be used to view status,perform force modes, and set schedules.There are presently 6 communicating sensors available. Two of thesesensors have LCD displays: E-BUS Digital Space Temperature OnlySensor or E-BUS Digital Space Temperature and Humidity Sensor.There is a communicating E-BUS Space Temperature and HumiditySensor and E-BUS Outdoor Air Temperature and Humidity Sensorwith no LCD display as well as an E-BUS Space CO2 Sensor, andE-BUS Duct CO2 Sensor with no LCD display.The DDC Controller provides for constant volume applications.NOTE:The internal USB communication port of the DDCController uses specialized USB drivers that must beinstalled on your Windows PC before communication to the device using PrismD can be established.To install the USB Drivers, follow the instructionsin the PrismD Technical Guide.DAIKIN DDC Controller Technical Guide Controls up to 2 Heat Stages Controls up to 2 Compressors Fan Proving Interlock Dirty Filter AlarmEmergency Shutdown Input (Smoke Detector/PhaseMonitor/Firestat or other Shutdown Conditions) Remote Start/Stop Control Title 24 Economizer Certified 7 day, 2 events per day schedule 14 Holiday Event Scheduling Optimal Start Daylight Savings Time Adjustment Trend Logging Capability Set up using a computer with PrismD software installedor with the System Manager Touch Screen II-G(sold separately)Can be operated Stand-Alone or connected to anetworked systemOn-board CommLink for Stand-Alone programmingusing a USB connection to a computer running PrismDsoftware On-board BACnet port for connection to anMS/TP network (See Appendix C)5

ZoneINSTALLATION & WIRINGImportant Wiring ConsiderationsGeneralZoneWARNING:Correct wiring of the DDC Controller is the most important factor inthe overall success of the controller installation process. In general,most DDC Controllers are factory installed and wired at the DAIKINfactory. Some of the following information pertains to field wiringand may not apply to your installation if it was pre-wired at thefactory. However, if troubleshooting of the controller is required, itis a good idea to be familiar with the system wiring, no matter if itwas factory or field wired.When using a single transformer to power morethan one controller or expansion module, thecorrect polarity must always be maintained between the boards. Failure to observe correctpolarity will result in damage to the DDCController.Please carefully read and apply the following information whenwiring the DDC Controller.1.All wiring is to be in accordance with local and nationalelectrical codes and specifications.2.All 24 VAC wiring must be connected so that all groundwires remain common. Failure to follow this procedurecan result in damage to the controller and connecteddevices.3.Minimum wire size for 24 VAC wiring should be18-gauge.4.Minimum wire size for all sensors should be 24-gauge.Some sensors require 2-conductor wire and some require3-or 4-conductor wire.Considerations5.Minimum wire size for 24 VAC thermostat wiringshould be 22 gauge.The DDC Controller must be connected to a 24 VAC power sourceof the proper size for the calculated VA load requirements. Alltransformer sizing should be based on the VA rating listed in Table 1.6.Be sure that all wiring connections are properly insertedand tightened into the terminal blocks. Do not allowwire strands to stick out and touch adjoining terminalswhich could potentially cause a short circuit.7.When communication wiring is to be used to interconnect DDC Controllers together or to connect to othercommunication devices, all wiring must be plenumrated, minimum 18-gauge, 2-conductor, twisted pair withshield.8.Before applying power to the DDC Controller,be sure to recheck all wiring connections andterminations thoroughly.Controller MountingSee Table 1 for a list of the required operating conditions for theDDC Controller.VA -00001DDC ControllerTemperatureControlDeviceThe DDC Controller
