INSTALLATION  
INSTALLATION INSTRUCTIONS FOR  
W A R N I N G  
• This Thermostat is a line voltage (120 / 240 Vac) control. Do not  
install it unless you are completely familiar with house wiring. If  
improperly handled, there can be a risk of electric shock hazard  
which may cause serious injury or death.  
• The thermostat is rated for normal full load current on a dual  
residential 20A circuit breaker or fuse block. Do not use on circuits  
protected by higher-rated over-current protection devices. Some  
sustained fault conditions can cause product failure.

• Do NOT connect to voltage different from the device rating.  
WARNING: Use Energizer® or DURACELL® Alkaline Batteries Only.

C A U T I O N  
• Disconnect power supply before making wire connections to  
prevent electrical shock or equipment damage.  
• All wiring must comply with applicable codes and ordinances.  
• Thermostats are designed to be used with appliances having a limit  
control.  
• Maximum load for this thermostat MUST NOT EXCEED 3800W,  
otherwise a potential fire hazard exists.  
Location:  
Install a vertical switch box for mounting the thermostat  
approximately 1.5 m (5 ft.) above the floor on an inside wall where the  
thermostat will be exposed to average room temperature. The  
thermostat must be placed away from concealed warm or cold water  
pipes, air ducts, or drafts from hallways, fireplaces or stairways to  
sense temperature properly. Do not place the thermostat above the  
heater.  
WIRING  
1. Disconnect power while installing. Double check that the  
thermostat is rated for the voltage and amperage load to be  
controlled.  
2. Remove the cover by carefully pressing the button at the bottom of  
the thermostat and swinging the body up and away.  
3. When replacing an old line voltage wall thermostat, remove it  
carefully to avoid damage to the insulation on the wiring. Check the  
old insulation for cracks, nicks, or fraying and apply certified  
electrical tape where necessary to achieve adequate insulation, or  
replace the wires in an approved fashion.  
4. Attach the wires with solderless wire connectors (provided). Be  
sure that all wire connectors are tight.

OPERATION  
This thermostat is “armchair programmable.” You can make any program or  
setting changes with the thermostat body off or on the wall thermostat base.  
The thermostat alternately displays the current time and the room  
temperature. It also displays the day of the week and the currently  
active control program that is controlling the temperature: MORN, DAY,  
EVE, or NIGHT. The set point temperature will appear in the right side  
of the display.  
CAUTION: Do not short the 120 / 240 Vac wires with the thermostat.  
The Built-In Programs

You can use the built-in  
programs as shown, or change  
them as you wish. Each day is  
divided into four periods. Each  
period has its own starting time  
and temperature.  
WARNING: To avoid the risk of fire hazard, all connections to  
aluminum conductors must be made using approved  
CO/ALR solderless wire connectors. Do not use the  
supplied solderless wire connectors.

INSTALLING BATTERIES  
Programming the thermostat  
The thermostat requires batteries to operate your furnace and retain its  
programming in memory. Replace the batteries when the LO BAT  
indicator appears in the display or at least once a year.  
You can change any of the preset times and/or temperatures to  
suit your schedules for the weekday and weekend programs. Each day  
is divided into four periods: Morning, Day, Evening, and Night.  
A blank programming chart is provided for you to record your  
temperature settings in that chart.  
NOTE: When replacing batteries, you have approximately 1 minute  
before the programs are lost.

ADVANCED FEATURES  
TEMPERATURE SWING  
A thermostat works by turning your heating on and off whenever  
the room temperature varies a certain number of degrees from the  
set-point temperature. This variation is the “swing.”  
Your system should cycle on about 3 to 6 times per hour. A  
smaller swing number increases the number of cycles, so room  
temperature is more constant. A larger swing number decreases the  
number of cycles, to save energy in most cases.

CHANGING FROM °F to °C AND A 12HR CLOCK TO A 24HR CLOCK  
• Warning: Making these changes will require you to reset the  
thermostat. Copy any of your customized programs onto the chart  
below. This will be your reference to reenter the programs  
afterward.  
• Located at the center of the circuit board of your thermostat are two  
dip switches.  
• To change to Celsius, move the top dip switch to the right.  
• To change to a 24HR clock, move the bottom dip switch to the right.  
• Press the reset key on the front of the thermostat for the changes to  
take effect.  
• Reprogram as necessary.
