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.
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.
