While in Override mode, the Override icon and the Oc-
cupied 1 icon will be displayed on the thermostat. The time
of day and the minutes remaining in Override mode will al-
ternate on the thermostat display.
The set points are adjustable with the UP ARROW and
DOWN ARROW keys during Override mode.
NOTE: If the thermostat is in Occupied mode and the Over-
ride button is pressed, the thermostat will go into Unoccu-
pied mode immediately. The thermostat will remain in Un-
occupied mode until the next Occupied start time.
KEYPAD LOCK — The thermostat has a keypad lockout
feature which will not acknowledge front panel buttons until
the lockout sequence is entered. To disable or lock the key-
pad, press and hold the Mode button. While holding down
the Mode button, press the UP and DOWN ARROW buttons
simultaneously. The ‘‘Locked’’ icon will appear on the
display.
The thermostat is unlocked by performing the same pro-
cedure. Press and hold the Mode button. While holding down
the Mode button, press the UP and DOWN ARROW buttons
simultaneously. The ‘‘Locked’’ icon will be removed from
the display.
MODE BUTTON OPERATION — The Mode button se-
lects the operating mode of the thermostat. If OFF is se-
lected, the thermostat will not enter Heating 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 thermostat will only enter Cooling
mode (if the room temperature 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 heat-
ing and cooling set points. If PROGRAM ON is selected,
the stored schedule is enabled and the thermostat will follow
the Occupied and Unoccupied schedules stored in its memory.
Auto-Changeover — 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.
NOTE: It is recommended that auto-changeover mode not
be used if the outdoor temperature is consistently lower than
50 F (10 C) or greater than 80 F (27 C). In these cases, select
Heating or Cooling mode only.
Set Clock — The Set Clock function allows the user to
change the time and day displayed on the thermostat. Press
and hold the Mode and Override buttons for 2 seconds to
enter Set Clock mode. See Fig. 3. The current time will blink
on and off. Press the UP ARROW or DOWN ARROW but-
ton until the correct time is shown. Hold down the buttons
to quickly move through the time display. The AM and PM
annunciators will automatically change. To scroll through by
hours only, press and hold the Override button while press-
ing the UP or DOWN ARROW button. To ensure the sched-
ules are properly followed, make sure that AM or PM is cor-
rect for the time chosen. When the correct time is shown,
press the Mode button to modify the day of the week. The
current day will blink on and off. Press the UP ARROW or
DOWN ARROW button until the correct day is shown. Press
and hold the Mode and Override buttons for 2 seconds again
to exit the Set Clock mode.
Programming Thermostat Schedules — Be-
fore programming the thermostat, plan the thermostat daily
schedule. The schedule is divided into 3 days (Saturday, Sun-
day, and Monday through Friday). The daily schedule for
Monday through Friday is the same. Each day can have 2
(Occupied 1, Unoccupied), 3 (Occupied 1, Occupied 2, Un-
occupied), or 4 (Occupied 1, Occupied 2, Occupied 3, Un-
occupied) time periods. Each occupied time period has a start
time, stop time, heating set point, and cooling set point. The
Occupied 1 and Unoccupied temperature set points are the
same for each day. The unoccupied time period has a heat-
ing set point and a cooling set point. The unoccupied time
period is active whenever an occupied time period is not ac-
tive. Fill in Table 1 on page 3 as an aid to programming the
daily schedules.

ules, perform the following procedure:
