Programming Heating and Cooling Schedule
IMPORTANT
Keep in mind that the up and down keys change the flashing number or word.
When multiple items are flashing, changes affect only one of the items.
The thermostat can control up to four different schedule periods per day:
Occupied1—Work arrival time. Period to keep space at a comfortable temperature.
Unocc1—Work exit time. Period to keep space at an energy-saving temperature.
Occupied2—Second occupied period.
Unocc2—Second unoccupied period.
NOTES:
— Available schedule times are at 15-minute intervals.
— With default settings, all four periods can be programmed. This can be
changed to allow only Occupied1 and Unocc1 programs. To use only
Occupied1 and Unocc1, see Step 8 in the Advanced Settings section.

Setting “System & Fan”
SETTING SYSTEM
The System selections vary based on the HVAC system type.
HEAT — thermostat controls the heating system.
OFF — both heating and cooling systems are off.
COOL — thermostat controls the cooling system.
AUTO — thermostat controls both the heating and cooling systems based on temperature.
9 63-2626
SETTING FAN
Fan selections vary based on the HVAC system type.
ON—fan runs continuously. Use this setting for improved air circulation or for more efficient
central air cleaning.
AUTO—fan is controlled by the system. Typically, the fan runs only during cooling or
heating operation.
Setting Temperature Overrides
There are three temperature override options:
— Hold Temperature Until
— Override, and
— Holiday.
HOLD TEMPERATURE UNTIL
Holds the temperature temporarily until the time set by the user, or the next scheduled
period time:
1. Press an arrow key or the Override key. TEMPORARY SET TO appears on the
screen. The time defaults to the next scheduled period start time.
2. Use the Up and Down keys to change the desired temperature.
NOTE: If HEAT or COOL begins to flash, your temporary setting is at, or beyond,
the deadband. The thermostat operates based on the override setting
throughout the hold time.
3. Press NEXT.
10 63-2626
NOTE: The ability to change settings remains for approximately seven seconds.
Once neither the temperature nor the time continue to flash, you must
restart at step 1 to make changes.
4. Use the Up and Down keys
to set the desired time for
the thermostat to resume
the programmed schedule.
NOTE: The installer setup
can limit the length
of time for an override to 1, 2, 3, or 4

Fan Status Displayed on Main Screen
AUTO—fan is controlled by the system.
ON—fan is continuously on.
When the thermostat is running the fan, the fan blade symbol appears next to FAN to
indicate the thermostat has the fan on.
NOTES:
— If the mode is Occupied, fan control is On. The only thing that allows the fan to
turn off during occupied periods is a manual fan override from On to Auto.
— If the mode is Unoccupied, fan control is the same as with the Auto setting.
This is true even when the display indicates “On”.
— If the thermostat is not controlling the fan, the fan blade symbol might not
appear even while the fan is running.
13 63-2626
Replacing Batteries
With proper power and connections, the
thermostat does not require batteries.
Thermostats with batteries provide a
warning when the batteries run low. This
warning flashes on the main screen for
approximately 30 days.
NOTES:
— If batteries are not replaced
when Low Battery warning is
flashing, the LO batt screen
displays continuously and
thermostat stops operating
until batteries are replaced.
— Despite the low battery indicator, it is recommended that you replace the
batteries once each year. Do this to prevent leakage and to prevent the
thermostat and HVAC system from shutting down due to lack of thermostat
battery power.
14 63-2626
M22383
Replace the batteries as follows:
1. Remove the thermostat
from the base by pulling it
straight out.
2. Install two new AA alkaline
batteries with proper
polarization.
NOTES:
— Always use AA
alkaline batteries.
— All programming
(Schedule, Date and
Time) information
is retained during
battery replacement.

a. Align the terminal screw
blocks with the pins on the
back of the thermostat.
b. Push the thermostat
straight onto the base.
NOTES:

Reading Remote Indoor Temperature
If connected to an installed remote
indoor temperature sensor, the
thermostat displays the indoor
temperature from the remote
sensor(s).
NOTE: When connected to an
installed remote indoor
temperature sensor, the
thermostat internal sensor
is not used.
ONE REMOTE INDOOR SENSOR
INSTALLED
If one remote indoor temperature
sensor is used, the screen showing
the Inside temperature reading
displays the temperature at the
indoor remote sensor location.
MULTIPLE REMOTE INDOOR SENSORS INSTALLED
If more than one remote indoor sensor is used, the screen showing the Inside temperature
reading displays the average of all the remote indoor sensors.

procedures are used to incorporate the temporary changes made with these keys. See the
Setting Temperature Overrides section for details.
PARTIAL LOCKOUT 2
This mode locks all keys except HOLIDAY and OVERRIDE:
— Selecting HOLIDAY sets the temperature to the Unoccupied setting. The temperature
setting cannot be changed. The number of days to hold the holiday can be changed.
After this time, the next Occupied period switches back to the program settings.
— Selecting OVERRIDE sets the temperature to the Occupied setting. The temperature
setting cannot be changed. The period of time to hold the override can be changed.
After this time, the next Unoccupied period switches back to the program settings.
— To cancel the temperature override and follow the programmed schedule, press
CANCEL.
20 63-2626
Temperature Recovery
The thermostat is equipped with a
feature to eliminate guesswork
when setting a schedule. That is,
the user need not know the amount
of time for the HVAC system to
bring the space to temperature
(without overshoot) prior to the
scheduled time.The thermostat
manages that automatically.
Simply program the desired time to
have space at comfort temperature.
In addition, program temperature to
comfort temperature. The
thermostat activates the heating or
cooling at the proper time to reach the set temperature at the scheduled time.
NOTE: The setpoint changes gradually to use economical stages and avoid overshoot.
For example—the space will be occupied at 8:00 AM and the desired temperature is 70°F.
Set the Occupied1 period for 8:00 AM and 70°F. The thermostat turns on the heat prior to
8:00 AM to raise the temperature to 70°F by 8:00 AM.
The thermostat provides an alert that the heating or cooling system is coming on before a
scheduled time by displaying “Recovery” on the screen.

Frequently Asked Questions and Answers
Q: When making changes, the wrong setting is being changed; Why?
A: Whatever is flashing on the screen is the item that the up and down buttons affect.
Q: The keys (some or all) do not work; why not?
A: Thermostat is locked. See Locked Keypad sections.
Q: Backlighting seems dim; is it designed to be dim?
A: When using batteries for power, install fresh AA alkaline batteries.
Q: Thermostat is asking for heating or cooling to come on (screen shows “Heat On” or
“Cool On” in display) but there is no heating or cooling running.
A: Call your local heating and/or cooling contractor to check your system.
Q: Why doesn’t the thermostat respond when I press a key?
A: Check to determine if the device is in the Locked mode. See Locked Keypad sections.
Q: Why doesn’t the fan run when the thermostat indicates “On”?
A: If the mode is Unoccupied, the fan control is the same as with the “Auto” setting. This is
true even when the display indicates "On".
