Carrier 30XW150-400 specifications Configuring Schedules with Navigator Display

Time Schedule — With Time Schedule Operating Type con- trol, the machine operates under a local schedule programmed by the user as long as the Enable/Off/Remote Contact switch is in the Enable or Remote Contact position (external contacts closed). To operate under this Operating Type Control (OPER) must be set to TIME SCHED (Time Schedule). Two Internal Time Schedules are available and must be field programmed. Time Schedule 1 (SCH1) is used for single set point On-Off control. Time Schedule 2 (SCH2) is used for dual set point On-Off and Occupied-Unoccupied set point control. The control will use the operating schedules as defined under the Time Clock mode in the Navigator display module.

If the chiller is to be controlled to a single set point, use Schedule 1 (SCH1). This type of schedule will start and stop the machine only. During the unoccupied times, the chiller will be off. If the chiller is to be controlled to 2 set points, occupied and unoccupied, use Schedule 2 (SCH2). This will cause the chiller to control to an occupied set point and an unoccupied set point. The machine will be able to provide cooling at any time.

To configure this option while using the Navigator™ dis- play, see Table 18.

Holiday Schedule — The unit control allows up to 16 holiday periods. All holidays are entered with numerical values. First enter the month (MON.x), then the day (DAY.x), then the duration (DUR.x) 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 this option for the Navigator display, see Table 19.

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.
