Reset, press and hold the Software Reset button for at least 5 seconds. The

COMPRESSOR PROTECTION BYPASS: This optional feature permits the
installer or service technician to temporarily disable the built in compressor
protection delays. This is most useful for diagnosing and testing the heating
and cooling systems after installation is complete, and should not be used
during normal operation. To activate this feature, start with the System
Mode switch in either the Heat or Cool positions, then change to the OFF
position. Press and hold the OK button for at least 5 second. The
thermostat will give a single beep sound to confirm that this feature has
been activated. All compressor protection delays (in all modes of operation)
will be disabled for 5 minutes. After the 5-minute duration has expired, the
thermostat will return to normal operation automatically.
This thermostat is powered by two “AA” Alkaline batteries. The batteries
should be replaced AT LEAST once per year to ensure reliable operation (or
sooner, if the “LO-BATTERY” icon appears at the bottom of the display
screen). The batteries are located on the back of the thermostat, at the top
of the circuit board. The front portion of the thermostat can be removed
from the back half by pulling straight outwards on the top and bottom of the
thermostat housing, at the large indentations that are present in the center
of the top and bottom edges.
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 to securely latch the front and back halves together
properly.
