5. Press the Program button to advance to the next time
period.
6. Perform Steps 2 through 5 until the times and tem-
perature 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 schedule
until a new one is entered. The schedule may need to
be updated for different seasons or prolonged changes in
temperature.
VII. OVERRIDING THE SCHEDULE
The schedule can be overridden in three ways, the Hold but-
ton can be pressed to lock in the current temperature set-
ting, the Up or Down buttons can be pressed to change the
desired temperature, or the Occupied button can be pressed
to change the unoccupied set points to OC1. The HOLD
annunciator will turn on and the desired temperature will
not change according to the program time or desired temper-
ature values. The HOLD will last indefinitely until the
HOLD button is pressed again. The user can still change the
desired temperature by using the Up and Down buttons.
When using the Up or Down buttons, the thermostat will use
the new set point until the next scheduled time period. At
the next scheduled time period the thermostat will revert
back to the programmed temperature values.
The Occupied override button can be used to force the ther-
mostat into Occupied mode.
VIII. DISPLAY OUTDOOR-AIR OR LEAVING-AIR
TEMPERATURE
When the Up and Down buttons are pressed at the same
time, the display will show the temperature of the sensor
wired to the thermostat. The temperature is displayed for
4 seconds with the letters “od” or “LA” (outdoor temperature
or leaving air temperature, respectively). The display then
returns to normal. If a sensor is not connected, the thermo-
stat has been configured for use with a remote room sensor,
or the reading is out of range, then “--” is displayed.
The valid temperature range for the outdoor-air sensor is
–38 to 145 F. The valid temperature range for the leaving-air
sensor is –38 to 145 F.
