TEMPERATURE SWING: The amount of temperature variation between load-on and load-off is changed by adjusting the
swing setting. The default value for this thermostat is #4, and the adjustment range is from #1 to #9. A smaller swing
number makes the temperature control more precise and constant, and increases the number of cycles per hour. A larger
swing number will produce a greater variation between load-on and load-off events, and decreases the number of cycles
per hour.
To adjust the Swing setting: Set the thermostat to OFF mode using the System Mode switch, and hold down the SAVE
button for at least 5 seconds. When the screen changes to a single digit, this is the current Swing setting value and it
can be adjusted using the UP or DOWN buttons. The thermostat will return back to the normal Run mode screen if no
b
uttons are pressed for 4 seconds.
TEMPERATURE CALIBRATION: This thermostat is accurately calibrated at the factory, and in most cases alteration to this
setting should not be required. The Calibration feature allows you to manually offset the room temperature measurement
by as much as plus or minus 5°F (3°C) degrees from its original value. 0°F (0°C) is the default setting.
To adjust the Calibration setting: Set the thermostat to OFF mode using the System Mode switch, press both
the UP and
DOWN together for at least 2 seconds. When the screen changes to a single digit, this is the current Calibration setting
value and it can be adjusted using the UP or DOWN buttons. The thermostat will return back to the normal Run mode
screen if no buttons are pressed for 4 seconds.
This thermostat is powered by two “AA” Alkaline batteries. The batteries should be replaced AT LEAST once per year (or
sooner, if the “LOW BAT” battery symbol appears in the display screen). When the LO BAT symbol is shown, the
temperature digits will also display the word “Lo”. The batteries are located on the back of the circuit board, and can be
accessed by pulling the front portion of the thermostat straight outwards and removing it from the wall. When installing
new batteries, we recommend using only brand new Energizer
®
or DURACELL
®
, “AA” size alkaline batteries. Please
observe the polarity markings shown in the battery compartment to ensure proper installation. When finished, line up the
front of the thermostat to the base, and firmly press together.
