SCHEDULE/ADVANCE DAY key
The SCHEDULE is a seven day daily schedule that al- lows one start/stop time per day. The schedule can be programmed Monday through Sunday with an alternate holiday schedule available. If no start/stop times are pro- grammed, the unit will run on demand, providing the chiller is not shut off on a unit or system shutdown. The daily schedule is considered “not programmed” when the times in the schedule are all zeros (00:00 AM).
To set the schedule, press the SCHEDULE/ADVANCE DAY key. The display will immediately show the follow- ing display.
M O N S T A R T | = | 0 0 | : | 0 0 | A M |
S T O P | = | 0 0 | : | 0 0 | A M |

The line under the 0 is the cursor. If the value is wrong, it may be changed by using the UP and DOWN arrow keys until correct. Pressing the ENTER/ADV key will enter the times and then move the cursor to the minute box. The operation is then repeated if necessary. This process may be followed until the hour, minutes, and meridian (AM or PM) of both the START and STOP points are set. After changing the meridian of the stop time, pressing the ENTER/ADV key will advance the schedule to the next day.
Whenever the daily schedule is changed for Monday, all the other days will change to the new Monday sched- ule. This means if the Monday times are not applicable for the whole week then the exceptional days would need to be reprogrammed to the desired schedule.

To page to a specific day press the SCHEDULE/AD- VANCE DAY key. The start and stop time of each day may be programmed differently using the UP and DOWN arrow, and ENTER/ADV keys.
After SUN (Sunday) schedule appears on the display a subsequent press of the SCHEDULE/ADVANCE DAY key will display the Holiday schedule. This is a two part display. The first reads:
H O L S T A R T | = | 0 0 | : | 0 0 | A M |

The times may be set using the same procedure as described above for the days of the week. After chang- ing the meridian of the stop time, pressing the ENTER/ ADV key will advance the schedule to the following dis- play:
S _ M T W T F S
H O L I D A Y N O T E D B Y *
The line below the empty space next to the S is the cursor and will move to the next empty space when the ENTER/ADV key is pressed. To set the Holiday, the cursor is moved to the space following the day of the week of the holiday and the UP arrow key is pressed. An * will appear in the space signifying that day as a holiday. The * can be removed by pressing the DOWN arrow key.
The Holiday schedule must be programmed weekly- once the holiday schedule runs , it will revert to the nor- mal daily schedule.
