Battery Replacement; Technical Assistance - Lux Products Smart Temp TX9100U Installation And Operating Instructions Manual

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.

BATTERY REPLACEMENT:

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 "-- -- LOW BATT -- --" 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
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.
