Built-in compressor protection
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). When
the safe wait time has elapsed, the
message stops flashing and the
compressor turns on.
Battery replacement
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.
Most settings are stored in non-
volatile (permanent) memory. Only
the clock and the day must be set
after you replace the batteries.
Pull at bottom to
remove thermostat from
wallplate.
Turn thermostat
over, insert fresh AAA
alkaline batteries,
then reinstall
thermostat.
Set the System switch to Off before removing
the batteries. Otherwise, the heating/cooling
system could remain activated even when
batteries are removed.
