4913.2. Protection Control For Cooling & Soft Dry Operation13.2.1. Outdoor Air Temperature ControlThe compressor operating frequency is regulated in accordance to the outdoor air temperature as shown in the diagram below.This control will begin 1 minute after the compressor starts.Compressor frequency will adjust base on Outdoor Air Temperature.13.2.2. Cooling Overload Controli. Pipe temperature limitation/restriction• Detects the Outdoor pipe temperature and carry out below restriction/limitation (Limit the compressor Operation frequency)• The compressor stop if outdoor pipe temperature exceeds 63°C.• If the compressor stops 4 times in 20 minutes, Timer LED blinking (F95: outdoor high pressure rise protection)13.2.3. Dew Prevention Control 11. To prevent dew formation at indoor unit discharge area.2. This control activated if:• Outdoor air temperature and Indoor pipe temperature judgment by microcontroller if fulfilled.• When Cooling or Dry mode is operated more than 20 minutes or more.3. This control stopped if:• Compressor stopped.• Remote control setting changed. (fan speed / temperature)• Outdoor air temperature and indoor intake temperature changed.4. Fan speed, angle of louver (vertical airflow angle) will be adjusted accordingly in this control.• Fan speed will be increased slowly if the unit is in quiet mode but no change in normal cooling mode.13.2.4. Dew Prevention Control 21. To prevent dew formation at indoor unit discharge area.2. This control starts if all conditions continue for 20 minutes:• Operated with Cooling or Soft Dry Mode.• Indoor intake temperature is between 25°C and 29°C.• Outdoor air temperature is less than 30°C.• Quiet Lo fan speed.3. This control stopped if:• When receive air swing change signal from Remote Control.4. The horizontal louver will be fixed at 26° (regardless of Auto or Manual Airflow Direction Setting)5. The vertical louver will be fixed front.13.2.5. Freeze Prevention Control 11. When indoor heat exchanger temperature is lower than 0°C continuously for six minutes, compressor will stop operating.2. Compressor will resume its operation three minutes after the indoor heat exchanger is higher than 5°C.3. At the same time, indoor fan speed will be higher than during its normal operation.4. If indoor heat exchanger temperature is higher than 5°C for five minutes, the fan speed will return to its normal operation.13.2.6. Freeze Prevention Control 21. Control start conditions• During Cooling operation and soft dry operation.- During thermo OFF condition, indoor intake temperature is less than 10°C or- Compressor stops for freeze prevention control• Either one of the conditions above occurs 5 times in 60 minutes.
