Troubleshooting Guide

failure, will restore those setting automatically
within 3 minutes after power returns.
• If the unit was in forced cooling mode, it will run in
this mode for 30 minutes and turn to auto mode with
temperature set to 24°C (76°F).
• If there is a power failure while the unit is running, the
compressor starts 3 minutes after the unit restarts. If
the unit was already off before the power failure, the
compressor starts 1 minute after the unit restarts.

4. Optional Functions
4.1 46°F / 8°C Heating
In heating mode, the temperature can be set to as low
as 46°F (8°C), preventing the indoor area and pipes from
freezing if unoccupied during severe cold weather.
4.2 Self clean
• If you press “Self Clean” when the unit is in cooling or
drying mode:
• For cooling models, the indoor unit will run in low
fan mode for a certain time, then ceases operation.
• For heat pump models, the indoor unit will run in
fan-only mode, then low heat, and finally in fan-
only mode.
• Self Clean keeps the indoor unit dry and prevents
mold growth.
• When matched with multi outdoor unit, this function
is unavailable.
4.3 Follow me
• If you press “Follow Me” on the remote, the indoor
unit will beep. This indicates the follow me function is
active.
• Once active, the remote control will send a signal
every 3 minutes, with no beeps. The unit automatically
sets the temperature according to the measurements
from the remote control.
• The unit will only change modes if the information
from the remote control makes it necessary, not from
the unit’s temperature setting.
• If the unit does not receive a signal for 7 minutes or
you press “Follow Me,” the function turns off. The
unit regulates temperature based on its own sensor
and settings.
4.4 Silence
• Press “Silence” on the remote control to enable the
SILENCE function. While this function is active, the
compressor frequency is maintained at a lower level
than F3. The indoor unit will run at faint breeze, which
reduces noise to the lowest possible level.
• When matched with multi outdoor unit, this function
is unavailable.
