Operating Frequency Calculation Formula:
Remarks:
When Freq. H is equal to 20 (XE9DK), 27 (XE12DK) for cooling, 25 (XE9DK), 32 (XE12DK) for heating or above, the Comp.
may run at the freq. higher than Fc or Fh up to max. freq. operation.
may run at the freq. higher than Fc or Fh up to max. freq. operation.
Best Amenity Control
Every 90s (Cooling), 120s (Heating) maintain same zone Freq. H + 1 until Fc, Fh.
8.1.3. Cooling Operation
8.1.3.1. Thermostat control
• Compressor is OFF when Intake Air Temperature - Internal Setting Temperature < -1.5°C.
• Compressor is ON after waiting for 3 minutes, if the Intake Air Temperature - Internal Setting Temperature > Compressor OFF
• Compressor is ON after waiting for 3 minutes, if the Intake Air Temperature - Internal Setting Temperature > Compressor OFF
point.

8.1.4.1. Thermostat control
• Compressor is OFF when Intake Air Temperature - Internal Setting Temperature < -2.5°C.
• Compressor is ON after waiting for 3 minutes, if the Intake Air Temperature - Internal Setting Temperature > Compressor OFF

8.1.5.1. Thermostat control
• Compressor is OFF when Intake Air Temperature - Internal Setting +1.0°C.
• Compressor is ON after waiting for 3 minutes, if the Intake Air Temperature - Internal Setting Temperature < Compressor OFF
• Compressor is ON after waiting for 3 minutes, if the Intake Air Temperature - Internal Setting Temperature < Compressor OFF
point.

Automatic Operation
This mode can be set using remote control and the operation is decided by remote control setting temperature, indoor intake air
temperature and outdoor air temperature.
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.

Example of operation mode chart adjustment:
From the above table, if remote control setting temperature = 25,
T1 = 25 + 7 = 32; T2 = 25 + 6 = 31; T3 = 25 - 7 = 18
The operation mode chart for this example is as 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.
