2 “AA” alkaline batteries are included
in the thermostat to keep time during a
power outage. They are also required for
armchair programming (see below).
If “LOW BATTERY” is displayed in the
scrolling message area, the batteries
are low and should be replaced with
fresh batteries. For best results use
premium brand alkaline batteries, such
as Duracell
®
or Energizer
®
.
