• In AUTO operation, the system selects a temperature setting and an appropriate operation mode (COOL or HEAT) based on
the room temperature at the start of the operation.
• The system automatically reselects setting at a regular interval to bring the room temperature to user-setting level.
• The computer chip works to rid the room of humidity while maintaining the temperature as much as possible. It automatically
controls temperature and airflow rate, so manual adjustment of these functions is unavailable.
• This air conditioner cools the room by blowing the hot air in the room outside, so if the outside temperature is high, the
performance of the air conditioner drops.
• Since this air conditioner heats the room by taking heat from outdoor air to indoors, the heating capacity becomes smaller in
lower outdoor temperatures. If the heating effect is insufficient, it is recommended to use another heating appliance in
combination with the air conditioner.
• The heat pump system heats the room by circulating hot air around all parts of the room. After the start of HEAT operation,
it takes some time before the room gets warmer.
• In HEAT operation, frost may occur on the outdoor unit and lower the heating capacity. In that case, the system switches
into defrosting operation to take away the frost.
• During defrosting operation, hot air does not flow out of indoor unit.
The air conditioner operates with the operation mode of your choice.
From the next time on, the air conditioner will operate with the same operation mode.
