1. When the air conditioner is in "Auto", "Cool", "Dry", and "Heat" modes, it may emit a
low continuous "hissing" sound, which is caused by the refrigerant flowing between the
Indoor Unit and the Outdoor Unit.
2. A "hissing" sound may be heard for a short time after the air conditioner stops
operation or during "defrosting", which is caused when the refrigerant stops flowing or
changes its flow.
3. When the air conditioner is in Cool mode or Dry mode, a small and continuous rustling
sound can be heard, which is caused by the drain pump.
4. When the air conditioner starts or stops running, you may hear a squeaking sound
which is produced by the expansion or shrinkage of parts or surrounding aesthetic
materials due to temperature change. The sound will disappear when the air conditioner
is running normally.
When the Indoor Unit reaches the set temperature, the air conditioner controller
automatically stops the compressor operation and switches to the fan only mode. When the
room temperature rises (in cooling mode) or falls (in heating mode) to a certain level, the
compressor is restarted and cooling or heating operation is resumed.
1. During the heating operation of the heat pump type air conditioner, the air conditioner
absorbs heat from the outdoor air and releases it to heat the indoor air. This is the heat
pump heating principle of the air conditioner.
2. When the heat pump runs in heating mode, the Outdoor Unit blows out cold air,
causing the outdoor temperature to drop. When the outdoor temperature is extremely
low, the heating capability of the air conditioner drops gradually. You are advised to use
other heating devices for heating.
All Indoor Units in the same air conditioning system can only operate in the same mode, for
example, cooling, heating or others. If Indoor Units are in different modes, a conflict will
occur, making the system unable to start. Make sure that all the Indoor Units operate in the
same mode.
For the same air conditioning system, if Outdoor Unit operates in changeover mode, the
main wired controller allows users to select modes supported by the Indoor Units, while the
wired controller of a non-master Indoor Unit displays the icon of "No heating or cooling
options". In this case, the mode setting is unavailable, and other Indoor Units operate in the
same mode as the master Indoor Unit.
