46Ice Storage OperationChiller operation can be configured to make and store ice. The en-ergy management module and an Ice Done Switch are required foroperation in the Ice Mode. In this configuration, the machine canoperate with up to three cooling set points: Cooling Setpoint 1 isused during the Occupied period, Cooling Setpoint 2 is usedduring the Unoccupied period when the ice build is complete (IceDone Switch is closed), and Cooling Ice Setpoint is used duringthe unoccupied period while ice is building (Ice Done Switch isopen). Refer to the 30XV Typical Field Wiring Schematic figureon page 227 for Ice Done Switch wiring.To configure this option with the Carrier Controller display:Broadcast ConfigurationThe 30XV chiller with Greenspeed® Intelligence is capable ofbroadcasting OAT, time, date, and holiday status to all elements inthe CCN system. In the stand-alone mode, broadcast must be acti-vated to utilize holiday schedules and adjust for daylight savingtime. If the chiller is to be connected to a CCN system, determinewhich system element is to be the network broadcaster and acti-vate broadcast in all other system elements. Broadcast is activatedand deactivated in the Carrier Controller Broadcast Menu (MainMenu Configuration Menu Broadcast MenuBrocasts).Only one element should be configured as a broadcaster. If abroadcast is activated by a device that has been designated as anetwork broadcaster, then broadcast time, date, and holiday statuswill be updated over the CCN system. If broadcast is enabled, abroadcast acknowledger must also be enabled. The acknowledgercannot be the same machine as the broadcasting machine.ACTIVATEThe Activate variable enables the broadcast function of the CarrierController controls. If this variable is set to 0, this function is notused and holiday schedules and daylight savings compensation arenot possible. Setting this variable to 1 allows the machine tobroadcast and receive broadcasts on the network. The followinginformation is broadcast: the time with compensation for daylightsavings, date, holiday flag, and the Outdoor Air Temperature.Set this variable to 2 for stand-alone OAT broadcast. With thisconfiguration, daylight saving time and holiday determinationwill be done without broadcasting through the bus.To configure this option with the Carrier Controller display:OAT BROADCASTTo enable the OAT broadcast, the unit broadcasting the tempera-ture must be configured with its own CCN Bus and CCN Address.Leaving the parameters at the factory default of 0 for the CCN Busand CCN Address disables the OAT Broadcast function. Onceconfigured, the first broadcast of OAT will be within 5 minutes.To configure this option with the Carrier Controller display:BROADCAST ACKNOWLEDGERThis configuration defines if the chiller will be used to ac-knowledge broadcast messages on the CCN bus. One broadcastacknowledger is required per bus, including secondary busescreated by the use of a bridge. The broadcast acknowledgermust be configured through the Network Service Tool.Alarm ControlALARM ROUTING CONTROLAlarms recorded on the chiller can be routed through the CCN. Toconfigure this option, the Carrier Controller controls must be con-figured to determine which CCN elements will receive and pro-cess alarms. Input for the decision consists of eight digits, each ofwhich can be set to either 0 or 1. Setting a digit to 1 specifies thatalarms will be sent to the system element that corresponds to thatdigit. Setting all digits to 0 disables alarm processing. The factorydefault is 00000000. See Fig. 44. The default setting is based onthe assumption that the unit will not be connected to a network. Ifthe network does not contain a ComfortVIEW™, Comfort-WORKS™, TeLink, DataLINK™, or BACLink module, enablingthis feature will only add unnecessary activity to the CCN com-munication bus.Typical configuration of the Alarm Routing variable is11010000. This Alarm Routing status will transmit alarms toComfortVIEW ™ software, TeLink, BACLink, and DataLINK.This option cannot be configured with the Carrier Controllerdisplay. To change the alarm control routing through the Net-work Service Tool, navigate to point ALRM_CNT in tableALARMDEF.Fig. 44 — Alarm Routing ControlDISPLAY NAME PATH VALUEIce ModeEnableMain MenuConfiguration MenuGeneral Configura-tionDrop Down Selection (YES/NO)Default = NoCooling IceSetpointMain MenuSetpoint TableDefault = 44°F (6.7°C)Range = –20 to 78.8°F (–29 to 26°C)DISPLAYNAME PATH VALUEActivateMain MenuConfiguration MenuBroadcast MenuBrocasts0 = Disabled1 = Broadcast time, date, holidayflag, and OAT2 = OAT broadcast only (Daylightsavings time and holiday determina-tion will be done without broadcast-ing through the bus)DISPLAY NAME PATH VALUEActivate Main MenuConfiguration MenuBroadcast MenuBrocastsRange = 0 to 2Default = 2OAT BroadcastBus # Range = 0 to 239Default = 0Element # Range = 0 to 239Default = 0DESCRIPTION STATUS POINTAlarm Routing 0 0 0 0 0 0 0 0 ALRM_CNTComfortVIEW™ or ComfortWORKS™TeLinkUnusedBACLink or DataLINK™Unused
