REPLACING THE BATTERIES

Your thermostat uses three AAA alkaline batteries. We

recommend Energizer

®

 batteries. 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 to 30 seconds of
taking out the old ones.

To replace:

■

Set the system switch to OFF.

■

Remove the thermostat from the wall. See page 17.

■

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 18.

■

Reprogram, if necessary.

POWER OUTAGES

Backup batteries will hold the programming and keep

the display on during most power outages. Once the
power is restored, the system will resume normal
operation.

If the display goes off when power is lost, either the

backup batteries need to be replaced or are not installed.
When power is restored, the display will flash 1:00 p.m. to
remind you to reprogram.
