Built-in compressor protection
Damage can occur if the compressor is restarted
too soon after shutdown. This feature forces
the compressor to wait for a few minutes before
restarting.
During the wait time, the display will flash the
message Cool On (or Heat On if you have a heat
pump). When the safe wait time has elapsed, the
message stops flashing and the compressor turns on.
Message flashes until safe
restart time has elapsed.

Battery replacement
Batteries are optional (to provide backup power) if your thermostat was wired to
run on AC power when installed. If your thermostat was not wired to run on AC
power, then batteries are required.
Install fresh batteries immediately when the low battery icon appears. The icon
appears about two months before the batteries are depleted.
Even if the low battery icon does not appear, you should replace batteries once a
year, or before leaving home for more than a month.
NOTE: When replacing batteries, alkaline batteries are recommended.
When the low battery
warning appears, press
gently to loosen the
thermostat and then
carefully pull it from
the wall mount.
Insert fresh alkaline AA
batteries and reinstall
thermostat.
