CCN LOADSHED CONTROLLED DEMAND LIMIT — To
configure Demand Limit for CCN Loadshed control, the unit Op-
erating Type Control must be in CCN control. With the Touch Pi-
lot™ display, the machine must be started in Network Mode.
Network control can be executed from the GENUNIT table.
The unit must be controlled by a Chillervisor module. The
Chillervisor module can force the demand limit variable and
directly control the capacity of the machine. Additionally, the
unit's set point will be artificially lowered to force the chiller to
load to the demand limit value.
Ice Storage Operation —
configured to make and store ice. The energy 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 Sche-
matic figure on page 117 for Ice Done Switch wiring.

Broadcast Configuration —
Greenspeed ® intelligence is capable of broadcasting out-
side-air temperature (OAT), time, date, and holiday status to
all elements in the CCN system. In the stand-alone mode,
broadcast must be activated to utilize holiday schedules and
adjust for daylight saving time. If the chiller is to be con-
nected to a CCN system, determine which system element is
to be the network broadcaster and activate broadcast in all
other system elements. Broadcast is activated and deactivat-
ed in the Touch Pilot Broadcast Menu (Main Menu  Con-
figuration Menu  Broadcast 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 en-
abled, a broadcast acknowledger must also be enabled. The ac-
knowledger cannot be the same machine as the broadcasting
machine.
ACTIVATE — The Activate variable enables the broadcast
function of the Touch Pilot 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

OAT BROADCAST — To enable the outside air temperature
(OAT) broadcast, the unit broadcasting the temperature must
be configured with its own CCN Bus and CCN Address. Leav-
ing 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.

BROADCAST ACKNOWLEDGER — This configuration
defines if the chiller will be used to acknowledge broadcast
messages on the CCN bus. One broadcast acknowledger is re-
quired 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 op-
tion, the Touch Pilot controls must be configured to determine
which CCN elements will receive and process 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. Set-
ting all digits to 0 disables alarm processing. The factory de-
fault is 00000000. See Fig. 37. 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, en-
abling this feature will only add unnecessary activity to the
CCN communication bus.
