1. To wire the thermostat determine which pair of wires are coming from the
breaker panel and which pair lead to the heater.
2. Take a black lead from the circuit breaker panel and attach it to the black
lead on the thermostat.
3. Take the black lead that goes to the heater and attach it to the red lead on
the thermostat. This will provide power to the heater when the thermostat
calls for heat. Attach the blue wire to the white wires.
4. Remove cover of thermostat by placing thumb on LCD display and
forefinger on top of cover, pulling cover back to expose mounting screws
and programming buttons. Slide battery cover off to expose lower
mounting
screw.
5. Push the wires carefully into the junction box making sure no wires are
pinched or obstruct the screws mounting the thermostat. Now attach the
thermostat to the 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 on 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.
* 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
The small 22 gauge wire connection on the back of the thermostat is for the
remote 40° activation. This is a volt-free set of control wires that can be used
with any switch, such as: window and door contacts, motion sensors, key
cards, hotel panels, anything that can make or break contact.
40° set back is activated on contact open.
