Built-In Compressor Protection; Battery Replacement - Honeywell FocusPRO 5000 User Manual

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 (for backup
power) if your thermostat was wired to
run on AC power when installed.
Install fresh batteries when the REPLACE
BATTERY warning begins flashing. The
warning flashes about two months
before the batteries are depleted.
Replace batteries once a year, or before
leaving home for more than a month.
All settings are permanently stored in
memory, and do not require battery
power.
