Set this variable to 2 for stand-alone units that are not con- nected to a CCN. With this configuration, daylight saving time and holiday determination will be done without broadcasting through the bus. This variable can only be changed when using the Touch Pilot display, ComfortVIEW™ software, or Network Service Tool. This variable cannot be changed with the Navigator display.

To configure this option with the Touch Pilot display:

BROADCAST ACKNOWLEDGER — This configuration defines if the chiller will be used to acknowledge broadcast messages on the CCN bus. One broadcast acknowledger is required per bus, including secondary buses created by the use of a bridge. This variable can only be changed with the Touch Pilot display, ComfortVIEW software, or Network Service Tool. This variable cannot be changed with the Navigator display.

Alarm Control

ALARM ROUTING CONTROL — Alarms recorded on the chiller can be routed through the CCN. To configure this op- tion, the ComfortLink control 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. 26. The default setting is is based on the assumption that the unit will not be connected to a net- work. If the network does not contain a ComfortVIEW, Com- fortWORKS®, TeLink, DataLINK™, or BAClink module, en- abling this feature will only add unnecessary activity to the CCN communication bus.

This option can be modified by the Touch Pilot display. It cannot be modified with the Navigator display.

Typical configuration of the Alarm Routing variable is 11010000. This Alarm Routing status will transmit alarms to ComfortVIEW software, TeLink, BAClink, and DataLINK.

ALARM EQUIPMENT PRIORITY — The ComfortVIEW device uses the equipment priority value when sorting alarms by level. The purpose of the equipment priority value is to de- termine the order in which to sort alarms that have the same level. A priority of 0 is the highest and would appear first when sorted. A priority of 7 would appear last when sorted. For ex- ample, if two chillers send out identical alarms, the chiller with the higher priority would be listed first. The default is 4. This variable can only be changed when using the Touch Pilot dis- play, ComfortVIEW software, or Network Service Tool. This variable cannot be changed with the Navigator™ display. To configure this option with the Touch Pilot™ display:

COMMUNICATION FAILURE RETRY TIME — This vari- able specifies the amount of time that will be allowed to elapse between alarm retries. Retries occur when an alarm is not acknowledged by a network alarm acknowledger, which may be either a ComfortVIEW software or TeLink. If acknowledge- ment is not received, the alarm will be re-transmitted after the number of minutes specified in this decision. This variable can only be changed with the Touch Pilot display, ComfortVIEW, or Network Service Tool. This variable cannot be changed with the Navigator display.
