The large numbers and letters on your
LCD screen make it easy to see. In low
light conditions, press the button on
top of the thermostat and the display
will light up for three seconds. For ten
minutes after pressing the light button,
pressing any other button will light the
display for ten seconds. The display
light uses power from the 3 “AA”
alkaline batteries installed. Excessive
use of the display light will reduce
battery life.

The thermostat uses 24 VAC power
supplied by the system for normal
operation. However, if the installed
“AA” batteries are providing sufficient
power, you can program the thermostat
away from the wall. If the thermostat
indicates low battery power (
CHECK
BATTERY
), refer to the Battery Back-
up feature (page 33).
