Set Current Time —
The Set Time/Temp button allows
the user to change the time displayed on the thermostat. Press
the Set Time/Temp button. The TIME annunciator will flash.
Press the Up and Down buttons until the correct time is shown.
Hold down the buttons to quickly move through the time dis-
play. The AM and PM annunciators will automatically change.
To ensure the schedules are properly followed, make sure that
AM or PM is correct for the time chosen. When the correct
time is shown, press the End button to exit the Set Time mode.
Reset Filter —
The Reset Filter function is initiated by
pressing the Hold and Occupied buttons simultaneously. The
Reset Filter function is used to clear the “Clean Filter” icon on
the display screen. The “Clean Filter” icon reminds the user
when it is time to change or clean the filter of the unit.
Unoccupied Override —
The Occupied button is only
active during unoccupied periods. The Occupied button is
inactive during occupied periods. If the thermostat is in unoc-
cupied mode and the user presses the Occupied button, the set
points are changed to the OC1 set points for heating and cool-
ing. The OC1 icon will flash to show the user that the thermo-
stat is in override.
The thermostat will remain in override until the next sched-
uled time period or for the number of allowed override hours
programmed in the thermostat configuration (Option 18)
whichever comes first.
NOTE: If the set point is changed during unoccupied override,
the thermostat will change the unoccupied 1 (UN1) set point.
Programming Thermostat Schedules —
Before
programming the thermostat, plan the thermostat daily sched-
ule. The schedule is divided into 7 days (Monday through Sun-
day). Each day has 4 time periods (OC1, UN1, OC2, UN2).
Each time period has a start time, heating set point, and cooling
set point. Fill in Table 1 below as an aid to programming the
daily schedules.
When choosing the times for OC1, UN1, OC2, and UN2,
the following rules must be followed:
• The maximum number of hours allowed from OC1 to
UN1, or from OC2 to UN2 is 12 hours. For example, if
OC1 has a value of 6:00 AM and UN1 had a value of
5:00 PM, this would be acceptable. If however, OC1 has
a value of 6:00 AM and UN1 has a value of 7:00 PM,
this would not be acceptable because the difference is
greater than 12 hours.
• The value of UN2 must be greater than or equal to the
value of OC2, while the value of OC2 must be greater
than or equal to the value of UN1, and the value of UN1
must be greater than or equal to OC1. For example,
acceptable values would be:
OC1 UN1 OC2 UN2
6:00 AM 5:00 PM 5:00 PM 10:00 PM
In the example above, the thermostat will be occupied from
6:00 AM to 10:00 PM. However, if the following values
were entered, the thermostat would not be occupied as one
may expect:
OC1 UN1 OC2 UN2
6:00 AM 7:00 PM 6:00 PM 12:00 AM
In the new example, the thermostat will display UN2 from
12:00 AM to 6:00 AM, then OC1 from 6:00 AM to 6:00 PM,
then OC2 from 6:00 PM to 7:00 PM, then UN1 from 7:00 PM
to 12:00 AM. The thermostat, in this example, would be occu-
pied from 6:00 AM to 7:00 PM because OC2 has a value less
than the value of UN1.
PROGRAMMING MODE — To program the daily sched-
ules, perform the following procedure:
1. Enter programming mode by pressing the Program
button. The PROGRAMMING annunciator will
appear on the thermostat display. The current day of
the schedule will be displayed and the current pro-
gramming time period of that day will be displayed.
The TIME annunciator will flash.
NOTE: If a programming button is not pushed for 2 minutes,
the thermostat will exit programming mode and any changes
made will be saved.
2. Press the Up and Down buttons to set the start time for
the schedule day and period shown.
3. Press the Set Time/Temp button once the correct time
is shown. The TIME annunciator will stop flashing
and the HEAT annunciator will flash.
4. The heating and cooling set points can now be pro-
grammed. The HEAT and COOL annunciators will
flash for the heating and cooling set points respec-
tively. The Set Time/Temp button is used to toggle
between the time, heating, and cooling set points. Use
the Up and Down buttons to raise and lower the tem-
perature set points.
NOTE: There must be at least 2 degrees difference between
the cooling and heating set points. The thermostat will auto-
matically change any set points closer than 2 degrees.
5. Press the Program button to advance to the next time
period.
6. Perform Steps 2 through 5 until the times and tempera-
ture set points have been entered for the entire day.
Press the Change Day button to move to the schedule
for the next day.
7. Repeat Steps 2 through 6 to program the remaining
schedule days. The Copy Previous Day button can be
used to copy the previous day’s schedule if the sched-
ules are the same.
8. After all the times and set points for each day have
been entered, press the End button to finish entering
the schedule.
NOTE: The thermostat will continue to follow the sched-
ule until a new one is entered. The schedule may need to
be updated for different seasons or prolonged changes in
temperature.
Table 1 — Daily Schedule Planner
NOTE: The cooling temperature set point must be at least 2 degrees higher than the heating temperature set point.
