1. To wire the thermostat determine which pair of wires come from the breaker panel
and which pair lead to the heater.
2. Attach a black lead from the circuit breaker panel to the black lead on the
thermostat. Attach the white lead from the circuit breaker panel to the black wire on
the thermostat.
3. Attach the black lead that goes to the heater to the red lead on the thermostat.
Attach the white lead that goes to the heater to the red lead of the thermostat. This
will provide power to the heater when the thermostat calls for heat.
4. Remove thermostat cover by placing thumb on LCD display, forefinger on cover top,
pulling cover back to expose mounting screws and programming buttons. Slide
battery cover off to expose lower mounting screw.
5. Push wires carefully into the junction box making sure none are pinched or obstruct
thermostat mounting screws. Attach thermostat to wall with the #6-32 Phillips head
screws provided.
6. Hold thermostat in wallbox and place screws in top and bottom mounting hole.
Attach to wallbox. Install batteries and replace cover.
7. Turn on power. Test by increasing set point to higher than room temperature by
tapping the Up button. There will be up to a 3 minute delay turning on. You will
hear a small click and “Heater On” will appear on the LCD; the heater should now
be on. Turn the thermostat down by tapping the Down arrow.
8. Differential Adjustment: Hold both temperature and buttons for 10
seconds. The screen will go blank then show one digit. This is the number of
degrees that the thermostat will over or undershoot the desired temperature.
Adjust the setting between 1° and 4° by tapping the or arrow. Adjust to
suit your comfort level.
9. OFF: Push the button to disconnect power to heater. Backlight will turn off in
“off”
position.
* To change the display from Fahrenheit to Celsius requires opening the thermostat and moving a small
jumper on circuit board. For assistance please contact the factory at (800) 603-5464 ext. 111
