Ice Storage Operation
Chiller operation can be configured to make and store ice. The en-
ergy management module and an Ice Done Switch are required for
operation in the Ice Mode. In this configuration, the machine can
operate with up to three cooling set points: Cooling Setpoint 1 is
used during the Occupied period, Cooling Setpoint 2 is used
during the Unoccupied period when the ice build is complete (Ice
Done Switch is closed), and Cooling Ice Setpoint is used during
the unoccupied period while ice is building (Ice Done Switch is
open). Refer to the 30XV Typical Field Wiring Schematic figure
on page 227 for Ice Done Switch wiring.
To configure this option with the Carrier Controller display:
Broadcast Configuration
The 30XV chiller with Greenspeed ® Intelligence is capable of
broadcasting OAT, time, date, and holiday status to all elements in
the CCN system. In the stand-alone mode, broadcast must be acti-
vated to utilize holiday schedules and adjust for daylight saving
time. If the chiller is to be connected to a CCN system, determine
which system element is to be the network broadcaster and acti-
vate broadcast in all other system elements. Broadcast is activated
and deactivated in the Carrier Controller Broadcast Menu ( Main
Menu

Configuration Menu



Brocasts ).
Only one element should be configured as a broadcaster. If a
broadcast is activated by a device that has been designated as a
network broadcaster, then broadcast time, date, and holiday status
will be updated over the CCN system. If broadcast is enabled, a
broadcast acknowledger must also be enabled. The acknowledger
cannot be the same machine as the broadcasting machine.
ACTIVATE
The Activate variable enables the broadcast function of the Carrier
Controller controls. If this variable is set to 0, this function is not
used and holiday schedules and daylight savings compensation are
not possible. Setting this variable to 1 allows the machine to
broadcast and receive broadcasts on the network. The following
information is broadcast: the time with compensation for daylight
savings, date, holiday flag, and the Outdoor Air Temperature.
Set this variable to 2 for stand-alone OAT broadcast. With this
configuration, daylight saving time and holiday determination
will be done without broadcasting through the bus.
To configure this option with the Carrier Controller display:
OAT BROADCAST
To 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 Bus
and CCN Address disables the OAT Broadcast function. Once
configured, the first broadcast of OAT will be within 5 minutes.
To configure this option with the Carrier Controller display:
BROADCAST ACKNOWLEDGER
This configuration defines if the chiller will be used to ac-
knowledge broadcast messages on the CCN bus. One broadcast
acknowledger is required per bus, including secondary buses
created by the use of a bridge. The broadcast acknowledger
must be configured through the Network Service Tool.
Alarm Control
ALARM ROUTING CONTROL
Alarms recorded on the chiller can be routed through the CCN. To
configure 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 of
which can be set to either 0 or 1. Setting a digit to 1 specifies that
alarms will be sent to the system element that corresponds to that
digit. Setting all digits to 0 disables alarm processing. The factory
default is 00000000. See Fig. 44. The default setting is based on
the assumption that the unit will not be connected to a network. If
the network does not contain a ComfortVIEW™, Comfort-
WORKS ™ , TeLink, DataLINK™, or BACLink module, enabling
this feature will only add unnecessary activity to the CCN com-
munication bus.
Typical configuration of the Alarm Routing variable is
11010000. This Alarm Routing status will transmit alarms to
ComfortVIEW
™
software, TeLink, BACLink, and DataLINK.
This option cannot be configured with the Carrier Controller
display. To change the alarm control routing through the Net-
work Service Tool, navigate to point ALRM_CNT in table
ALARMDEF .
