CONTROL SYSTEM When compressor is switched to OFF and the heat sink temperature is above 55 degrees, the outdoor fan will remain ON in low speed for up to 3 minutes. EEV (Electronic Expansion Vavle) Control EEV Control for DCI25/35 EEV opening is defined as EEV = EEV + EEV is the initial EEV opening as a function of the compressor frequency, operation mode, unit...

CONTROL SYSTEM Heat Mode NLOAD is calculated according to the difference between actual room temperature and user set point temperature by fuzzy 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 31
CONTROL SYSTEM 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.
