8.1.2.2.4. The frequency changed method
1. When intake-setting remains for 30 seconds in a domain after shifting to relative control, a tap is adjusted according to the
domain and frequency changes relatively to the present condition.
2. A suction-setup to other domains by load sudden change (remote control setting change, open air introduction, etc.).
When it moves, addition or subtraction tap is changed at the time of the following renewal of data.
3. When the load change was furthermore carried out and a suction-setup separates from the domain of relative control, it goes
to the clause of initial frequency and operation frequency is determined.
8.1.2.3. The frequency determination method (Soft Dry operation control)
8.1.2.3.1. Basic specification
The domain directions data (intake-setting) transmitted from indoor determines a changed part of frequency.
Then, a directed changed part changes frequency to the present frequency.
Change of frequency may be 1 tap = 1Hz.
It applies to cooling correspondingly.
8.1.2.3.2. Initial frequency determination
It shifts to initial frequency after a starting frequency end.

8.1.2.3.3. The frequency change method
1. When (suction-setup) remains in a domain for 30 seconds, after shifting to relative control, a tap is adjusted according to the
domain and frequency changes relatively to the present condition.
2. A suction-setup is to other domains by load sudden change (remote control setting, open air introduction, etc.). When it moves,
an addition-and-subtraction tap is changed from the time of the following renewal of data.
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. Soft Dry Operation
8.1.4.1. 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
• Compressor is ON after waiting for 3 minutes, if the Intake Air Temperature - Internal Setting Temperature > Compressor OFF
point.
8.1.5. Heating Operation
8.1.5.1. 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
• 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 - 3 = 22; 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.

8.1.7. Indoor Fan Motor Operation
A. Basic Rotation Speed (rpm)
• Required rotation speed for fan is set to respond to the remote control setting (10 rpm unit)
