Program Overview
This programmable thermostat can have up to four setpoints per day (MORN, DAY, EVE, NIGHT). Each of these setpoints
will have a time, temperature and programmable fan setting. The thermostat is pre-programmed with setpoints that
meet the EPA’s Energy Star
®
requirements. The use of these setpoints can greatly reduce energy bills for the average
household. If the setpoints do not meet the needs of your household, they are fully adjustable to any settings desired.
This thermostat will monitor the time of day and turn the system on or off, based on the temperature differential, to
maintain the programmed or manually selected setpoint temperature.
To save money and energy, you can adjust these setpoint times and temperatures to provide set-back periods in
program mode during the day or at night. The Energy Efficient Recovery (EER™) feature looks ahead up to 2 hours
prior to the end of the set-back (or set-up) period to begin monitoring system performance and calculating when to
turn on your system. It also determines whether the auxiliary heat or cool stages should be activated prior to setpoint
time to meet your chosen setpoint temperature. The thermostat will indicate “EER” in the display when this program
feature is active. The EER™ feature will lock out the auxiliary stages until 20 minutes prior to the upcoming setpoint
time to utilize the most energy efficient first stage. The auxiliary stages of heating and cooling will be available after
this lock-out period to maintain the setpoint temperature should the system not be able to keep up with the heating
or cooling demand.
PROGRAMMING
Selecting ˚F/˚C
The thermostat displays temperatures in degrees Fahrenheit. If you wish to change the
readout to Celsius:
1. Press and hold SET button while pressing
∨
button. Release both buttons. The display will switch
from Fahrenheit to Celsius. If you wish to switch back to Fahrenheit, simply repeat this step.
NOTE: All differential control is done in˚F even though ˚C is selected as your display choice.

Your room temperature rises above the COOL setpoint programmed
temperature setting, the thermostat will activate the COOL program. If the
temperature continues to increase, the thermostat will turn on the COOL mode
and COOL will slowly flash in the display, indicating that it is in operation. When
the room temperature decreases to meet the COOL program setpoint
temperature, the thermostat will stop the cooling system. COOL will be
indicated in the display as active, but will not flash.
If the room temperature decreases below the HEAT setpoint programmed
temperature setting, the thermostat will activate the HEAT program. If the
temperature continues to decrease, the thermostat will turn on the heating
system and HEAT will slowly flash in the display. This indicates that the heating
system is currently in operation. When the room temperature increases to meet
the HEAT program setpoint temperature, the thermostat will stop the heating
system. HEAT will be indicated in the display as active, but will not flash.
NOTE: AUTO (Auto Changeover) operation can only be selected using the
SYSTEM button while in PROGRAM mode. If the AUTO program feature is not
functioning properly, see "CHANGING DIP SWITCH SETTINGS" to make sure
AUTO CHANGEOVER was selected during installation.
NOTE: To change your current dead band setting, you must change a dip switch
located on the back of the thermostat. See “CHANGING DIP SWITCH
SETTINGS” section to change the dead band setting to either 3˚ or 5˚. Changing
a dip switch setting will require resetting the thermostat to register the new
selection. This will erase previously entered program.
