ALLOW CONTINUOUS FAN DURING UNOCCUPIED
HOURS (20) — The fan can be configured by the user to run
continuously (set to ON) or only during heating or cooling (set
to AUTO). When the fan is set to ON (run continuously), the
Allow Continuous Fan During Unoccupied Hours configura-
tion determines whether the fan will run during unoccupied
periods when heating or cooling is not active.
When the configuration is set to ON and the fan is set to
ON, the fan will run continuously during unoccupied periods,
even when heating or cooling is not active.
When the configuration is set to OF, the fan will run during
unoccupied periods only when heating or cooling is active.
The default is On.

Step 10 — Programming Thermostat Sched-
ules —
Before programming the thermostat, plan the ther-
mostat daily schedule. The schedule is divided into 7 days
(Monday through Sunday). 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 3 as an aid to pro-
gramming the daily schedules.
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
3 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 start flashing.
4. The heating and cooling set points can now be pro-
grammed. The HEAT and COOL annunciators are dis-
played for the heating and cooling set points
respectively. The Set Time/Temp button is used to tog-
gle between the heating and cooling set points and the
time. Use the Up and Down buttons to raise and lower
the temperature set points.
NOTE: There must be at least 3 degrees difference
between the cooling and heating set points. The ther-
mostat will automatically change any set points closer
than 3 degrees.
