Maintaining Your Thermostat; Replacing The Batteries - Honeywell Programmable Thermostat Owner's Manual

MAINTAINING YOUR THERMOSTAT

REPLACING THE BATTERIES

Your thermostat uses three AA or
AAA alkaline batteries, depending
on model. See the instructions
inside the thermostat door to
determine the size. The display will
flash "REPL BAT" when the
batteries get low. Unless the
display is blank (indicating the
batteries are dead) when you start,
you won't have to reprogram the
thermostat if you can insert the
new batteries within 20-30 seconds
of taking out the old ones.
To replace:
If your thermostat has a system
switch, set it to OFF.
Remove the thermostat from the
wall. See page 31.
Lift the batteries out of the
holder.
Insert the new batteries, making
sure the positive (+) terminals all
face toward the right.
Replace the thermostat on the
wall. See page 32.
Reprogram, if necessary.
