For example, ifeconomizer commanded position (EC.CP) is forced, the Navigatordisplay shows “80f”, where the “f” is blinking to signify a force onthe point. The Scrolling Marquee display shows “80.” Where the“.” is blinking to signify a force on the point. Remove the force byselecting the point that is forced with the key ENTER and thenpressing the up and down arrow keys simultaneously.Depending on the unit model, factory-installed options andfield-installed accessories, some of the items in the various Modecategories may not apply.System Pilott and Touch Pilot DevicesThe System Pilot device (33PILOT--01) and Touch Pilot device(33CNTPILOT) can be used as CCN communicationuser--interfaces. These devices can be put on the CCN bus andaddressed to communicate with any other device on the network.Unlike the Scrolling Marquee and Navigator, these pilots read the48/50PD’s CCN tables and the units CCN points can be monitored,forced, or configured.IMPORTANT: Multiple zoning application is NOTrecommended at this time with the PD products.Additionally, the System Pilot device can serve as a wall--mountedtemperature sensor for space temperature measurement. Theoccupant can use the System Pilot device to change set points. Asecurity feature is provided to limit access of features forunauthorized users. See Fig. 3 for System Pilot device details.CCN Tables and DisplayIn addition to the unit--mounted Scrolling Marquee display, theuser can also access the same information through the CCN tablesby using the Service tool or other CCN programs/devices. Thevariable names used for the CCN tables and the Scrolling Marqueemenus may be different and more items may be displayed in theCCN tables. Details on the CCN tables are included with the localdisplay menus in Appendix A. Appendix A is structured towardsthe organization of the local display (Scrolling Marquee) menus.Because of the variety of CCN programs and devices, the CCNtables, sub--tables, and points are referenced within thatorganization.Table 2 — Scrolling Marquee Mode and Menu Display StructureRUNSTATUSSERVICETEST TEMPERATURES PRESSURES SETPOINTS INPUTS OUTPUTS CONFIGURATION TIMECLOCKOPERATINGMODESALARMSAuto ViewofRun Status(VIEW)↓SoftwareVersionNumbers(VERS)↓ControlModes(MODE)↓CoolingStatus(COOL)↓HeatingStatus(HEAT)↓EconomizerStatus(ECON)↓ComponentRun Hours(HRS)↓ComponentStarts(STRT)Service TestMode(TEST)↓Test IndependentOutputs(INDP)↓Test Fans(FANS)↓Test Cooling(COOL)↓Test Heating(HEAT)AirTemperatures(AIR.T)↓RefrigerantTemperatures(REF.T)GeneralInputs(GEN.I)↓CurrentSensor Inputs(CS.IN)↓Air QualityInputs(AIR.Q)FanOutputs(FANS)↓CoolOutputs(COOL)↓HeatOutputs(HEAT)↓EconomizerOutputs(ECON)↓AlarmRelay(ALRM)DisplayConfiguration(DISP)↓UnitConfiguration(UNIT)↓CoolingConfiguration(COOL)↓HeatingConfiguration(HEAT)↓EconomizerConfiguration(ECON)↓Air QualityCfg.(AIR.Q)↓Alarm RelayConfig.(ALM.O)↓PIDConfiguration(PID)↓SensorCalibration(TRIM)↓CCNConfiguration(CCN)Time of Day(TIME)↓Month, DateDay andYear(DATE)↓DaylightSavingsTime(DST)↓Local TimeSchedule(SCH.L)↓LocalHolidaySchedules(HOL.L)ControlModes(MODE)↓Cool ModeDiagnostic(COOL)↓Heat ModeDiagnostic(HEAT)↓EconomizerDiagnostic(ECON)↓DemandListing(DMD.L)Reset AllCurrentAlarms(R.CURR)↓ResetAlarmHistory(R.HIST)↓CurrentlyActiveAlarms(CURR)↓AlarmHIstory(HIST)48/50PD
