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
phrase “LO BATT” appears in the display screen). The batteries are located on
the back of the thermostat’s circuit board. The front portion of the thermostat
can be removed from the back half by using the tabs on the top edge of the
thermostat housing.
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.
BATTERY GRAPHIC: Anytime that batteries are
physically present in the thermostat, there will be
a visual indication of the remaining battery life
available on the thermostat’s display screen.
When brand new batteries are installed in the
battery compartment, this graphic should indicate
full battery life remaining with all bars present.
Over time, as the battery life decreases to the
point of having only 1 bar left, the Temperature
and Clock digits will start to alternate between
showing their normal content, and the words “LO
BATT”. At this point the batteries will need to be replaced as soon as practical to
avoid uninterrupted operation of your heating and/or cooling system. In most
cases, the thermostat will be capable of providing you approximately two months
of normal operation once the point of 1 bar left has been reached, and the screen
shows the words “LO BATT”.
