Short-Cycle Protection.
Your thermostat is designed to
protect your system against
premature compressor failure by
“locking out” the compressor. This
ensures that the compressor will stay
off for at least five minutes on each
cycle. When the thermostat is in
compressor lock-out, the word
COOL will flash. During this
period, the compressor will not be
energized.
