CONTROL SYSTEM 11.3.2 Target Frequency Setting The compressor target frequency is a function of the NLOAD number sent from the indoor controller and the outdoor air temperature. Basic Target Frequency Setting: NLOAD Target Frequency Maximum frequency 10 < NLOAD < 127 Interpolated value between minimum and maximum frequency Minimum frequency Compressor is stopped... - Page 40 CONTROL SYSTEM 11.4 Indoor Fan Control 10 Indoor fan speeds are determined for each model. 5 speeds for cool/dry/fan modes and 5 speeds for heat mode. When user sets the indoor fan speed to a fixed speed (Low/ Medium/ High), unit will operate constantly at set speed.
- Page 41 CONTROL SYSTEM 11.7 EEV (electronic Expansion valve) Control EEV opening is defined as EEV = EEV + EEV • is the initial EEV opening as a function of the compressor frequency, operation mode, unit model and capacity. • is a correction value for the EEV opening that is based on the compressor temperature.
- Page 42 CONTROL SYSTEM 11.14 Heat Mode NLOAD is calculated according to the difference between actual room temperature and user set point temperature by PI control. In high/ medium/ low indoor fan user setting, unit will operate fan in selected speed. In AutoFan user setting, fan speed will be adjusted automatically according to the calculated NLOAD.
- Page 43 CONTROL SYSTEM 11.16 Dry Mode As long as room temperature is higher then the set point, indoor fan will work in low speed and compressor will work between 0 and MaxNLOADIF1C Hz. When the room temperature is lower than the set point, compressor will be switched OFF and indoor fan will cycle 3 minutes OFF, 1 minute ON.

When Power Up – the whole outdoor unit controller, including the wiring, is under HIGH VOLTAGE!!! Never open the Outdoor unit before turning off the Power!!! When turned off, the system is still charged (400V)!!! It takes about 3 Min. to discharge the system. Touching the controller before discharging may cause an electrical shock!!! For safe handling of the controller please refer to section 1.6 below.
