Holiday Schedule — For the Touch Pilot display, the control allows up to 16 holiday periods. All holidays are entered with numerical values. To configure, first change the month (Holi- day Start Month), then the day (Holiday Start Day), then the duration (Holiday Duration) of the holiday period in days. If a holiday in included in one of the Occupied Time Periods of the schedule, the machine will follow that operating condition for the holiday. In the following examples, the holidays July 4 and December 25-26 are programmed for Holiday 1 and Holiday 2, respectively. To configure these holidays with the Touch Pilot display, see Table 16. To configure Holidays with the Naviga- tor display, check the H (holiday) schedule on the Schedule screen and program in the desired occupied times. See Fig. 16.

Timed Override — With the Touch Pilot display only, each time schedule can be overridden to keep the chiller in an Occupied mode (Timed Override Hours) for 1, 2, 3 or 4 hours

on a one-time basis. To configure this option for the Touch Pilot display:

DISPLAY NAME	PATH	LINE	VALUE
		NO.
Timed Override	Config\OCCDEFCS\	1	Range: 0 to 4
Hours	OCC1P01S or OCC1P02S		Default: 0

If configured for a timed override, the override can be can- celled by changing the Timed Override Hours to 0.

CCN Global Time Schedule — A CCN global schedule can be used if desired. The schedule number can be set anywhere from 65 to 99 for operation under a CCN global schedule. The 30XW chillers can be configured to follow a CCN Global Time Schedule broadcast by another system element. The ComfortVIEW™ Network Manager’s Configure and Modify commands or the Service Tool’s Modify/Names function must be used to change the number of the Occupancy Equipment Part Table Name (OCC1P01E) to the Global Schedule Num- ber. The Schedule Number can be set from 65 to 99 (OCC1P65E to OCC1P99E).

The Occupancy Supervisory Part table name (OCC1P01S) number must be changed to configure the unit to broadcast a Global Time Schedule. The Schedule Number can be set from 65 to 99 (OCC1P65S to OCC1P99S). When OCC1PxxS is set to a value greater than 64, an occupancy flag is broadcast over the CCN every time it transitions from occupied to unoccupied or vice-versa. By configuring their appropriate Time Schedule decisions to the same number, other devices on the network can follow this same schedule. The Enable/Off/Remote Contact must be in the Enable position or the Remote Contact position with the contacts closed for the unit to operate. The Unit Run Status (STAT) will indicate the current status of the machine (OFF, RUNNING, STOPPING or DELAY), depending on the schedule. The unit Occupied status (OCC) will indicate the current occupied schedule according to the schedule, either NO or YES. The Status Unit Control Type (CTRL) will be LOCAL OFF when the switch is Off. The Status Unit Control Type will be CCN when the Enable/Off/Remote Contact switch input is On.

Refer to Appendix F for more detailed instructions regard- ing global schedules and the i-Vu®device.

CCN Mode — To allow machine control by CCN commands, press the Start/Stop button on the Touch Pilot™ display. The Equipment Start screen will be displayed. Select CCN Mode. The unit will be controlled by a CCN command to the CCN Chiller Start/Stop variable. An external CCN device, such as Chillervisor, controls the On/Off state of the machine. When controlled by a Chillervisor, it is recommended that the Auto Start When SM Lost configuration be set to Yes. In the event of a loss of communication with the network, the machine will start and be controlled locally.

Careful evaluation of chilled water plant control should be reviewed. In the event local control is established, be sure that all pumps, valves, and other devices are capable of operating properly. The control will ignore the position of Enable/Off/ Remote Contact switch. The Run Status variable will indicate the current status of the machine — OFF, RUNNING, DELAY, or READY. The Control Type variable will change to CCN. The Operating Type variable will change to CCN.

For dual chiller control applications, the slave chiller must be enabled using the CCN Mode button.

Remote Mode — To allow machine to start and stop via a remote contact closure, press the Start/Stop button on the Touch Pilot display. The Equipment Start screen will be dis- played. Select Remote Mode. The unit will be controlled by the Enable/Off/Remote Contact switch (SW1). Switching the En- able/Off/Remote Contact switch to the Enable or Remote Contact position (external contacts closed) will force the unit into an occupied state. In this mode, all CCN network force
