Selecting Yes, then pressing mode will copy the previous day's program and then will ask the same copy question again If yes is setected each time, this routine will repeat until Saturday is copied to Sunday After Satur- day is copied to Sunday, the copy command is unavailable.

ft no is selected, as in previous steps, flashing prompts for input will appear for start and stop times for Occupied 1. If more than one occupied period was selected in Step 1 on page 3, then cool/heat set points, and start/stop times for additional occupied periods will be prompted.

PROGRAMMING NOTES

•If only one Occupied period is selected in Step 1 on page 3, Occupied 2 and 3 programming steps are skipped. Further, if only 2 occupied periods are selected, Occupied 3 programming steps are skipped.

•Heat and Cool set points for Occupied 1 are the same for every day of the week. Heat and Cool set points for Occupied 2 and 3 can be adjusted differ- ently for weekdays and weekends, if desired.

•If the start time is set later in the day than the stop time, the program will run from the start time to midnight and from midnight to the stop time on the same day. For example: 9:00pm start, 8:00am stop, on Monday, In this example the program will run from 12:00am Monday to 8:00am Monday and again from 9:00pm Monday to 12:00pm Monday,

•The Unoccupied settings take effect at all times when: (1) the program is on and (2) the current time is outside a preset occupied period. For this reason start and stop times are not necessary for unoccupied.

•If the same start and stop times are programmed in for an occupied period, then it will run 24 hours.

•If one occupied period starts and stops within another occupied period the lower occupied num- ber has priority. For example: If Occupied 3 is pro- grammed to be "on" 24 hours, and Occupied 2 is programmed to run that day, then Occupied 2 set- tings will take over from Occupied 3 between Occupied 2 start and stop times.
