During the programming process, you will have access to 4
program time periods; WAKE, DAY, EVE, and SLEEP. You
will be able to select program start times and the heat/cool
set points for each time period.
1. Decide on a program schedule that you desire. Table 1
is an example of what already exists in the thermostat as
the Energy Star recommended settings.
2. Press and release the SET button repeatedly until the
screen displays ...daily schedule in the center of the
screen. The list of the days of the week will be dis-
played on the left.
3. Press and release the soft button under the days of the
week until the day or days you want to program are
displayed.
4. Look at the column to the right of the days of the week.
This column displays the time period (wake, day, eve,
or sleep ). To set the wake time, press and release the
soft button under the time period until wake is dis-
played, press the soft button under the hour or minute,
and then press the up or down button to change the
time.
5. Set the heating set point temperature for that time
period by pressing and releasing the soft button under
the heat set at: temperature. Then press the up or down
button until the desired heat set point temperature is
displayed.
6. Set the cooling set point temperature for that time
period by pressing and releasing the soft button under
the cool set at: temperature. Then press the up or down
button until the desired cooling set point temperature is
displayed.
7. Repeat this process for each of the three remaining time
periods - day, evening and sleep - by first pressing the
soft button under the time period to select it. Then use
the soft buttons and the up or down button to change
the start time, the heating set point, and the cooling set
point.
8. To set the schedule for another day, press and release
the soft button under the days of the week until the day
or days you want to program are displayed.
9. Repeat steps 4 through 7 to program each day.
10. Press the DONE button when complete.
Programming the Auxiliary Device Schedule
In addition to the primary program schedule, the I/O board
provides an auxiliary relay for auxiliary control capability.
The auxiliary device program schedule allows the user to
automatically control an auxiliary residential device with 4
program periods throughout the day (wake, day, eve,
sleep). Each period allows the user to set the start time and
the desired state of the auxiliary device (either ON or OFF)
for that period. The program schedule for weekdays and
weekends can be set independently.
1. Decide on a program schedule that you desire. Table 4 is
an example of an auxiliary program schedule.
2. To begin programming the auxiliary schedule, press and
hold the SET button for at least 10 seconds. When
auxiliary programming mode is active the display will
show the icon AUXILIARY and the current program
period (wake, day, eve, sleep) will be displayed in place
of the room temperature display.
3. Press and release the soft key below the days of the week
until the weekday icons (Mo Tu Wed Thur Fri) are
displayed.
4. Press and release the soft key below the period (wake,
day, eve, sleep) until the wake period is displayed.
5. Press the soft key below the hour and then set the
desired start hour for the wake period by pressing the UP
or DOWN button.
6. Press the soft key below the minute and then set the
desired start minute for the wake period by pressing the
UP or DOWN button.
7. Press the soft key below the relay state (either “On” or
“OF”) and then press the UP or DOWN button to toggle
the relay state for the current period On or OF (Off).
8. Press the soft key below the wake program period to
change to the next period (day). Repeat steps 5 through
7 to set the start time and relay state for the day period.
9. Use the soft key below the program period to select the
next period and repeat the procedure.
10. After the 4 (wake, day, eve, sleep) weekday periods are
programmed, press the soft key below the day of the
week to display the SAT and SUN icons. Repeat the
procedure to program the weekend auxiliary schedule.
11. Press the DONE button to exit programming mode.
Hold Function
When the HOLD function is active you can change your
programmed temperature settings and hold the temperature
at a specific setting without the temperature changing
during the next programmed period.
1. Open the thermostat door.
2. Press and release the SCHEDULE button located at the
top of the display until the triangle icon appears before
the HOLD icon.
3. The set point temperature will be displayed in the lower
right. To change the set point temperature, press the up
or down button. The temperature will stay at the new
setting until you release the HOLD (see Step 5 below).
4. To change the heating set point temperature when the
cooling temperature is displayed - and vice versa - press
and release the MODE button located at the top of the
display until the triangle icon appears before the desired
mode - heat or cool. Then press the up or down button
to change the set point temperature.
5. To return the temperature to the pre-set level for that time
period (release the HOLD), press the SCHEDULE button
until the arrow moves to FOLLOW SCHEDULE.
6. Close the door.
TROUBLESHOOTING
If the thermostat display does not power up after power is
applied, check the Rc/Rh and C terminals for 24 Vac. If 24
Vac is present, check the voltage between Vg and V+. This
voltage will be approximately 12 to 20 Vdc. If voltage is
present, check the polarity to make sure it is wired correctly.
The display will not power up if polarity is reversed. Table 2
can be used as a troubleshooting tool for determining
which outputs will be active for a particular configuration
and each operating mode.
