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,
press and hold both the NEXT and HOLD buttons, while also perform a
single press of the Hardware Reset button (the LCD display screen will
become fully populated). Continue to hold the NEXT and HOLD buttons
until the LCD display screen returns to normal. 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 “LOW BATT” icon appears at the top 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.
