13.2.5 Automatic operation

• This mode can be set using remote control and the operation is decided by remote control setting temperature,

remote control operation mode, indoor intake temperature and outdoor air temperature.

• During operation mode judgment, indoor fan motor (with speed of Lo-) and outdoor fan motor are running for 30

seconds to detect the indoor intake and outdoor air temperature. The operation mode is decided based on below

chart.

Outdoor air

temperature (°C)

Values of T1, T2, and T3 depend on remote control setting temperature, as shown in below table. After the

adjustment of T1, T2 and T3 values, the operation mode for that particular environment and remote control setting is

judged and performed, based on the above operation mode chart, every 30 minutes.

Remote control setting temperature (°C) T1 T2 T3

16 ~ 18 +10 -2 -5

19 ~ 22 +8 -3 -7

23 ~ 26 +7 -3 -7

27 ~ 30 +6 -3 -8

There is a temperature shifting on T1, T2 and T3 if the operation mode judged is changed from cooling/ soft dry to

heating or vice versa.

Operation mode change from Temperature shifts (°C)

Cooling/ Soft dry → Heating -2

Heating → Cooling/ Soft dry +2

Example of operation mode chart adjustment:

From the above table, if remote control setting temperature = 25,

T1 = 25 + 7 = 32; T2 = 25 – 3 = 22; T3 = 25 -7 =18

The operation mode chart for this example is shown in below figure and the operation mode to be performed will

depend on indoor intake air temperature and outdoor air temperature at the time when the judgment is made.
