Built-in compressor protection
Change filter (RTH2300 only)
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.
If the filter reminder is turned
on during installation, the words
Change Filter
will flash on the
screen when the filter needs to be
replaced.
After you replace the air filter,
press and hold the
RUN
button for
3 seconds to reset the alert.
