changes temporarily, requiring the
temperature to be at a comfort level 24
hours/day.
UNOCC: In UNOCC mode, the AQ251 holds the
temperature of UNOCCUPIED programs
(LEAVE and SLEEP). This might be used if
the building will be unoccupied for an
extended period of time, such as a vacation
period.
There are two ways to set the schedule program times for
WAKE, LEAVE, RETRN, and SLEEP:
— One day at a time
— All days at the same time
1. One day at a time programming:
• Select EDIT DAILY from the Program Settings sub-
menu.
• A list of four program times per day displays,
showing the factory pre-set times for all programs:
MON WAKE 6:00A
MON LEAVE 8:00A
MON RETRN 4:30P
MON SLEEP 10:00P
TUE WAKE 6:00A
TUE LEAVE 8:00A
TUE RETRN 4:30P
TUE SLEEP 10:00P
…
SAT WAKE 6:00A
SAT LEAVE --:--
SAT RETRN --:--
SAT SLEEP 10:00P
SUN WAKE 6:00A
SUN LEAVE --:--
SUN RETRN --:--
SUN SLEEP 10:00P
• Any of the times can be changed by scrolling to that
line and pressing the + or – button until the desired
program time is displayed.
2. Programming all days at the same time:
• Select EDIT ALL DAYS from the Program Settings
sub-menu.
• A sub-menu displays where you can change the
WAKE program time for all days, the LEAVE
program time for all days, etc.
• When all four programs have been set, select the
COPY TO ALL DAYS option. This displays the
prompt: COPY TO ALL DAYS - ARE YOU SURE?.
Select Yes by positioning the indicator arrow at YES
and press the OK button.
• Next, the same list of days as EDIT DAILY
(described in step 1) displays, except that all days
now show the times for the WAKE, LEAVE, RETRN,
and SLEEP programs that you set in the EDIT ALL
DAYS menu.
• If you do not want all days of the week to have the
same program schedule (e.g., weekdays different
than weekends), you can now scroll down and
change the program times for certain days by
positioning the indicator arrow beside the program
time to change and using the + or – button to
increase or decrease the scheduled program time.
When the program times have been set for all days, press the
Home button to leave the programming menus and return to
the Home Page display. All settings take effect immediately.
NOTES:
1. Schedule times are in 15-minute intervals.
2. To have the AQ251 ignore a program change
(and therefore keep the previous program's set-
point temperature), position the cursor beside the
period to be ignored and press the OK button.
The AQ251 will display “--:--” beside that program
and, when operating, will continue with the previ-
ous program's setpoint until the next program
change.
