Settings using the indoor unit operation switches
The main body operation switch should only be used in emergencies when the remote control is
lost or broken, its battery has run out, or it is otherwise unusable.
Operation mode
• Pressing the main body operation switch cycles through the following operation modes: cooling
→
off
→
heating
→
off
→
cooling, etc. Since the operation mode is not displayed, you have to
judge what mode the unit is in by feeling whether the air coming out of the vent is cold or hot.
Swing Setting
• The unit will operate with the previous setting.
NOTE
NOTE
DRY mode AUTO or COOL or HEAT or FAN mode
The air flow rate setting is not variable.
Three levels of air flow rate setting from “ ” to “ ”
plus “ ” are available.
• If the settings were made with the operation switch, the ON/OFF TIMER operation and NIGHT SET
MODE are cleared.
Note on HEAT operation
• 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 rec-
ommended 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 heating operation, it takes some time before the room gets warmer.
• In heating 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.
Note on DRY operation
• The computer chip works to rid the room of humidity while maintaining the temperature as much as possible.
It automatically controls temperature and fan strength, so manual adjustment of these functions is unavailable.
Note on AUTO operation
• In AUTO operation, the system selects 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.
• If you do not like AUTO operation, you can manually select the operation mode and setting you like.
Note on air flow rate setting
• At smaller air flow rates, the cooling (heating) effect is also smaller.
