12.1.4. Heating Operation
12.1.4.1. Thermostat control
• Compressor is OFF when Intake Air Temperature - Internal Setting Temperature > +2.0°C.
• Compressor is ON after waiting for 3 minutes, if the Intake Air Temperature - Internal Setting Temperature < Compressor OFF
point.
12.1.5. 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 air 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.
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.
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.
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
Remote Control Setting Temperature (°C) T1 T2 T3
16 ~ 18 +10 -3 -5
19 ~ 22 +8 -3 -7
23 ~ 26 +7 -3 -7
27 ~ 30 +6 -3 -8
Operation Mode change from Temperature shifts (°C)
Cooling/Soft Dry → Heating -2
Heating → Cooling/Soft Dry +2
