●
On replacement installations, mount the new thermostat  
in place of the old one unless the conditions listed below  
suggest otherwise. On new installations, follow the  
guidelines listed below.  
Route the wires through the open areas in the base  
plate above the terminals. Hold the base against the wall,  
with the wires coming through. Position the base for the  
best appearance (to hide any marks from an old thermo-  
stat). Attach the base to the wall with the two screws pro-  
vided.  
●
Do not locate in a damp area. This can lead to corro-  
sion that will shorten thermostat life.  
●
Do not locate where air circulation is poor, such as in a 3.5. WIRING  
corner or an alcove; or behind an open door.

WARNINGS: 1. A B wire is sometimes used as a  
common wire. Connecting a common B wire to the B termi-  
nal in these systems will likely cause damage to the thermo-  
stat and/or HVAC system. Do not connect a wire to the B ter-  
minal if you are unsure whether it may be wired to a system  
common.

4.1.4 MODES  
●
Turn the power back on to your heating and/or air con-  
Because of your thermostats great versatility not all  
modes will be applicable to your application. The mode  
selections available to you are determined by settings in  
the Installer Setup Menu. Often the unit’s mode is dis-  
played during program run. When a unit has first been  
powered up with the dial in the Run position, your ther-  
mostat will begin to control your heating and/or air con-  
ditioning system according to it’s default ENERGY STAR  
approved program in AUTOCHANGE mode.  
ditioning system.  
●
Verify that the system and its fan are operating proper-  
ly. When set to a high temperature, the heating system  
should provide warm air after a short time. Likewise a  
cooling system should provide cool air after a short time.  
Usually sound from the furnace and air conditioning units  
can be heard while they are running. The rush of moving  
air should be heard within a short time after either has  
been started.  
4.1.4.1 OVERRIDE  
NOTE: If you have an electric system and the blower does not  
operate after installation, verify that the electric/gas option in  
installer set up is set to Electric.  
During run, either the Heat or Cool set point temperature  
may be altered with the temperature UP/DOWN arrow  
button. T Override will be displayed in line two of the dis-  
play. The adjusted temperature will remain the set tem-  
perature until the next program period begins. Then, tem-  
perature settings will return to program control.  
●
Installation is now complete.  
4. OPERATION  
4.1. OPERATING BASICS  
4.1.1 UP/DOWN ARROW CHANGE KEYS  
There are two arrow keys just the right of the units dis-  
play. They are used to adjust set temperatures, and  
change other settings.

in the associated direction.  
4.1.1.2 CHANGING OTHER SETTINGS  
The AUTOCHANGE mode allows your thermostat to  
switch between Heat and Cool modes of temperature  
control automatically.  
If there are many choices for a value, usually that setting  
will automatically advance by holding one of the arrow  
keys. Some settings though, must be changed one press  
at a time.  
●
AUTOCHANGE may not be available or applicable in  
your installation.  
●
To enter AUTOCHANGE mode if it is available, press  
the MODE button repeatedly until the display indicates  
that the unit is in AUTOCHANGE mode.  
4.1.2 SET DAY AND TIME  
The time used by your thermostat for temperature con-  
trol is that displayed by the unit. To set the correct time  
after the unit has been unpowered or after software reset:  
●
In AUTOCHANGE mode, you can determine whether  
your thermostat will call for heating or cooling (at that  
time) by whether HEAT SET or COOL SET is visible on  
the units display.  
●
Open the drop down door on the front of the thermo-  
stat. Rotate the dial to the SET DAY/TIME position. Use  
the UP key to advance the day to the current day of the  
week.

for 20 seconds.  
4.2.2 KEYBOARD LOCK  
Two types of Keyboard locks allow owners/operators to  
prevent unauthorized changes to the thermostats set-  
tings. The two types of locks are full and partial. When  
the thermostat is locked, a three digit code is set. That  
code must be reentered before locked settings can be  
changed without performing a software reset off the unit.  
●
You can force heating or cooling to be the active mode  
by pressing and releasing both arrow keys at the same  
time until the desired mode is indicated. After, the unit  
will then switch modes as necessary to control tempera-  
ture.

than 15 minutes for an Smart recovery to be initiated.  
●
Maximum Smart recovery time is one hour.  
●
AUX heat will not be activated during the first half hour  
of a Smart recovery. Then it will only be activated if nec-  
essary to achieve the programmed temperature by the  
beginning of the next period.

4.3.2.2 CLEAN  
This enables the CLEAN CYCLE® feature. The FAN icon  
alone in the display denotes that the fan is maintaining  
the programmed minimum run time; it will also run addi-  
tional time as required to maintain temperature control.  
The algorithm used avoids additional fan time when the  
minimum run time has been met over the last hour  
through temperature control. Minimum fan run times are  
met by running one third the hourly requirement at twen-  
ty minute intervals.

ignored by your thermostat that is an indicator that you  
should modify your program so that the recovery can be  
achieved within the 1 hour limit.  
●
A Smart recovery may not be initiated for 48 hours  
after the units programs have been changed. This allows  
the unit to gather the data necessary to predict a Smart  
recovery time.

Fan programming is similar to temperature program-  
ming. It has four consecutive periods, which are inde-  
pendent of the four temperature periods. The default set-  
ting for your systems fan requires it to run only as  
required by your environmental system. It may be pro-  
grammed to maintain a minimum run time on an hourly  
basis, or run continuously.
