12. Operation Control 12.1 Basic Function Inverter control, which equipped with a microcomputer in determining the most suitable operating mode as time passes, automatically adjusts output power for maximum comfort always. In order to achieve the suitable operating mode, the microcomputer maintains the set temperature by measuring the temperature of the environment and performing temperature shifting.
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 and indoor intake air temperature. During operation mode judgment, indoor fan motor (with speed of Lo-) is running for 30 seconds to detect the indoor intake air temperature.
[Heating] According to indoor pipe temperature, automatic heating fan speed is determined as follows. B. Feedback control Immediately after the fan motor started, feedback control is performed once every second. During fan motor on, if fan motor feedback ≥ 2550 rpm or < 50 rpm continue for 10 seconds, then fan motor error counter increase, fan motor is then stop and restart.
Automatic vertical airflow direction can be set using remote control; the vane swings up and down within the angles as stated above. For heating mode operation, the angle of the vane depends on the indoor heat exchanger temperature as Figure 1 below. It does not swing during fan motor stop. When the air conditioner is stopped using remote control, the vane will shift to close position.
12.6 Sleep Mode Operation SLEEP To maximise comfort while sleeping (CANCEL) This operation provides you with a comfortable environment while sleeping. It will automatically adjust the sleep pattern temperature during the activation period. The indoor unit indicator will dim when this operation is activated. This is not applicable if the indicator brightness has been manually dimmed.
12.8 Indication Panel POWER TIMER Color Green Orange Light ON Operation ON Timer Setting ON Light OFF Operation OFF Timer Setting OFF Note: If POWER LED is blinking, the possible operation of the unit are Hot Start, during Deice operation, operation mode judgment, or ON timer sampling.
12.11 Powerful Mode Operation When the powerful mode is selected, the internal setting temperature will shift lower up to 2°C (for Cooling/Soft Dry) or higher up to 3.5°C (for Heating) than remote control setting temperature for 20 minutes to achieve the setting temperature quickly.
