|
Heating | 0°C to 24°C approx. | 27°C or less | - |
Cooling | 21°C to 43°C approx. | 16°C to 32°C approx. | 80% or less |
Dehumidifying | 18°C to 43°C approx. | 16°C to 32°C approx. | - |
If the outdoor temperature is as low as 0°C, the heating capacity drops up to 70~80% depending on the operating condition.
If you use the air conditioner in temperatures over 32°C (indoor temperature), the cooling capacity may drop.

| ||||
|
| closed. |
|
|
| |||
|
|
|
|
|
|
|
|
|
| Heating capacity | The heat pump inside the air conditioner absorbs heat from outside air and brings itindoors. |
| |||||
|
| If the temperature of the outside air drops, the air conditioner heats less. If the room is not warm |
| |||||
|
| enough, use an additional heating appliance. |
| |||||
|
|
|
|
|
|
|
| |

|
| Therefore, turn the air conditioner on in advance. |
| |||||
|
|
|
|
|
|
|

| Frost | When you select the Heat mode, frost may form in the outdoor unit due to low temperature |
| |||||
|
| and high humidity. |
| |||||
|
| If this happens: |
| |||||
|
| The heating operation is stopped. |
| |||||
|

| |||||
| outdoor temperatures | the fan and the compressor of the outdoor unit may stop periodically. |
| |||||
|
| This is normal; wait until the air conditioner turns on again. |
| |||||
