OCC: In OCC mode, the AQ252 holds the temperature
of OCCUPIED programs (WAKE and RETURN). This
might be used if the occupancy pattern of the building
changes temporarily, requiring the temperature to be at
a comfort level 24 hours/day.
UNOCC: In UNOCC mode, the AQ252 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 AQ252 ignore a program change
(and therefore keep the previous program's
setpoint temperature), position the cursor
beside the period to be ignored and press the
OK button. The AQ252 will display “--:--”
beside that program and, when operating, will
continue with the previous program's setpoint
until the next program change.
