This feature helps prevent damage to the
compressor in your air conditioning or heat
pump system.
Damage can occur if the compressor is restarted
too soon after shutdown. This feature forces the
compressor to wait 5 minutes before restarting.
During the wait time, the display will flash the
message Cool On (or Heat On if you have a
heat pump model). When the safe wait time has
elapsed, the message stops flashing and the
compressor turns on.
Message flashes until
safe restart time has
elapsed.

Install two fresh AAA batteries when Lo Batt
flashes on the screen. Lo Batt appears for
60 days before the batteries are depleted.
Replace batteries once a year, or when you
will be away for more than a month.
The settings are stored in non-volatile
(permanent) memory and are thus
preserved when the thermostat is without
batteries.
Pull at bottom to
remove thermostat
from wallplate.
Turn thermostat over, insert
fresh AAA alkaline batteries,
then reinstall thermostat.
