Fig. 6 Ð Start Time Display

8.The Stop Time for Occupied 1 will be displayed. Use the UP ARROW and DOWN ARROW buttons to raise or lower the time until the desired Stop Time is shown. Press the Mode button.

9.The On/Off icon will be displayed. Use the UP ARROW to turn the Occupied 1 period ON for this day. Use the DOWN ARROW to turn the Occupied 1 period OFF for this day.

10.Repeat Steps 2 through 9 to program the remaining sched- ule for occupied periods 2 and 3 (if selected in Step 1).

11.The Copy command can be used to copy the previous day's schedule if the schedules are the same. The copy command becomes available after all the occupied periods are programmed in a day. Use the UP ARROW to change the copy command to YES. Use the DOWN ARROW to change the copy command to NO. Press the Mode button when the choice has been made. See Fig. 7.

If NO was selected, the schedule will automatically change to the next day and the user must enter the occupied and unoccupied schedules for that day.

NOTE: Occupied 1 schedule heating and cooling set points are the same for each day. Occupied 2 and 3 set points may be set to different values for each day of the week.

If YES was selected, the schedule will be copied to the next day. The schedule copy may be repeated until Sun- day is reached. The Sunday schedule cannot be copied to Monday.

12.After all the times and set points for each day have been entered, press the Program button to ®nish entering the schedule.

NOTE: The thermostat will continue to follow the sched- ule until a new one is entered.

·If only one occupied schedule is selected, the Occu- pied 2 and 3 schedules are skipped.

·If the start time is set later in the day than the stop time, the program will run from midnight of that day to the stop time and then from the start time to midnight.

·If the same start and stop times are programmed for an occupancy schedule, the thermostat will be in Occupied mode for 24 hours.

·If one occupied period starts or stops within another occupied period, the lower numbered schedule has pri- ority. For example, if schedule Occupied 3 is running for 24 hours and occupied schedule 2 comes on from 1 to 3 PM, the set points from Occupied 2 are in effect from 1 to 3 PM.

OVERRIDING THE SCHEDULE Ð The schedule can be overridden during operation by pressing the UP or DOWN ARROW buttons to change the desired temperature. The ther- mostat will use the new set point until the next scheduled time period starts.

OPERATION

The Mode button selects the operating mode of the ther- mostat. If OFF is selected, the thermostat will not enter Heat- ing or Cooling mode. If HEAT is selected, the thermostat will only enter Heating mode (if the room temperature is below the heating set point). If COOL is selected, the ther- mostat will only enter Cooling mode (if the room tempera- ture is above the cooling set point). If AUTO is selected, the thermostat will enter Heating or Cooling mode based on the room temperature and the heating and cooling set points. If PROGRAM ON is selected, the stored schedule is enabled and the thermostat will follow the Occupied and Unoc- cupied schedules stored in its memory.

Auto-Changeover Ð When the thermostat mode is set to AUTO, the thermostat will provide automatic changeover from Heating to Cooling mode and Cooling to Heating mode when required. The thermostat will automatically switch to maintain the desired temperature setting. The thermostat does not need to be manually changed from heating to cooling or cooling to heating operation.

Two-Stage Operation Ð The second stage of heat or cool is turned on when the ®rst stage has been on for a mini- mum of 2 minutes and the temperature differential from the set point is equal to or greater than the set point plus the deadband plus 2 degrees.

Clock Backup Ð In the event of a power loss, the ther- mostat will keep time for a minimum of 48 hours without external power or batteries.

Fan Operation Ð If Fan On is selected, the fan will run continuously during occupied schedule (except when Mode is switched to OFF). The fan will be off during unoccupied schedule except during heating or cooling operation.

If Fan On is not selected, the fan will only operate during heating or cooling operation.
