Arrow and Fan buttons together (increase tempera-
ture). This will make the triangle stay on and turn Cool
Stage 1 on. For actual outputs, refer to Table 4, making
sure the correct row from the table is selected. To turn
off, raise cooling set point above the room tempera-
ture. Cool Stage 1 and the triangle will turn off within
a few seconds. If system has 2 cooling stages, it will
start on Cool Stage 1 and proceed to Cool Stage 2 in
15 minutes due to a staging timer which requires
15 minutes between successive stages. The Up Arrow
and Fan buttons together (increase temperature) cannot
be used to defeat this timer. This timer can be defeated
by reducing the set point to more than 5 degrees below
room temperature, bringing on a Cool Stage 2 demand
within 5 seconds. Remember: 2-stage cooling units
often have a 1-minute off time between low and high,
so the thermostat's demand will not show immediately
as a change in the outdoor unit. It will show immedi-
ately as an increase in the indoor fan speed.
6. To test, press the Mode button until E HEAT indicator
turns on. This will allow operation of auxiliary heat
only. Raising the set point above room temperature
will turn on the first stage of auxiliary heating (W/
W1). Raising the set point more than 5 degrees above
room temperature will advance to full heat, if it is
available (O/W2 or Y1/W2 will come on—see
Table 4). Reducing set point below room temperature
will turn all heat off.
Step 7 — Select Thermostat Operation
Settings —
Thermostat operation should already be con-
figured. Set the Fan and Mode configurations to their desired
settings. Press the Up and Down Arrow buttons to select the
desired comfort temperature.
Step 8 — Set Current Time —
button allows the user to change the time displayed on the ther-
mostat. Press the Set Time/Temp button. The display will show
the blinking TIME indicator above the time display. Press the
Up and Down Arrow buttons until the correct time is shown.
Hold down the buttons to move quickly through the time dis-
play. The AM and PM indicators 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.
Step 9 — Set Current Day —
ton will change the day of the week shown on the thermostat
display to the next day. If a schedule has been entered, the ther-
mostat will follow the schedule of the newly selected day of the
week.
Step 10 — Programming Thermostat Sched-
ules —
Before programming the thermostat, plan the ther-
mostat daily schedule. The schedule is divided into 4 time
periods (WAKE, DAY, EVE, SLEEP). Each time period has
a start time, heating set point, and cooling set point. Fill in
the schedule table on page 16 as an aid to programming the
daily schedules.
PROGRAMMING MODE — To program the daily schedules,
perform the following procedure:
1. Enter Programming mode by pressing the Program
button. The PROGRAMMING indicator will appear
on the thermostat display. The current day of the
The Set Time/Temp
The Change Day but-
13
schedule will be displayed above the clock and the cur-
rent programming time period of that day will be dis-
played. The TIME indicator 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 Arrow buttons to set the
desired start time for the schedule day and period
shown. Time selection is in 15-minute increments.
3. Press the Set Time/Temp button once the correct time
is shown. The TIME indicator will stop flashing and
the HEAT indicator will flash.
4. Using the daily comfort schedule as a guide, program
the heating and cooling settings. The HEAT and
COOL indicators will flash for the heating and cooling
settings respectively. The Set Time/Temp button is
used to toggle between the time, heating, and cooling
settings. Use the Up and Down Arrow buttons to raise
and lower the temperature set points.
NOTE: There must be at least 2 degrees difference
between the cooling and heating settings. The thermo-
stat will automatically change any settings 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 settings 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 settings 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.
OVERRIDING PROGRAMMED SCHEDULE — The
schedule can be overridden in 2 ways: the Hold button can be
pressed to lock in the current temperature setting or the Up and
Down Arrow buttons can be pressed to change the desired
temperature. The thermostat will use the new set points until
the next scheduled time period starts. Once the Hold button is
pressed, any adjustments made will last indefinitely until the
Hold button is pressed again.
