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.
Set the System switch to Off before removing
the batteries. Otherwise, the heating/cooling
system could remain activated even when
batteries are removed.
Turn thermostat over,
insert fresh AAA
alkaline batteries, then
reinstall thermostat.
