12.2.8. Four-way Valve Operation Detection Control (Switching Abnormality betweenCooling and Heating)In Cooling operation1. When indoor heat exchanger temperature exceeds 45°C in 4 minutes after compressor starts, compressor will be stopped.2. If the above excess occurs 4 times per 30 minutes, timer LED is to be blinking. (“F11” is to be confirmed.)In Heating operation1. When indoor heat exchanger temperature is below 0°C in 4 minutes after compressor starts, compressor will be stopped.2. If the above excess occurs 4 times per 30 minutes, timer LED is to be blinking. (“F11” is to be confirmed.)12.2.9. Anti-Freezing Control (Cooling and Dry operations)Limit of Cooling power1. When temperature of indoor heat exchanger is below 5°C, operating frequency will be decreased.2. When temperature of indoor heat exchanger exceeds 7°C, operating frequency will be increased. (But, up to programmedfrequency.)3. When temperature of indoor heat exchanger is below 0°C continuously for 6 minutes, compressor will be stopped.4. Timer LED is not blinking. (“F99” is memorized, then.)Limit of Indoor fan speed• When temperature of indoor heat exchanger is below 6°C (2°C at Dry) continuously for 6 minutes, indoor fan speed will beincreased by 50 rpm.12.2.10. Outdoor Air Temperature ControlIn Cooling and Dry operations1. When outdoor air temperature is below 25°C, the maximum power will be limited up to about 80 - 100% of the rated power.2. When outdoor air temperature is below 18°C, the maximum power will be limited up to about 50 - 100% of the rated power.3. When outdoor air temperature is below 11°C, the maximum power will be limited up to about 26 - 81% of the rated power.12.2.11. Indoor Intake Air Temperature Control (Heating operation)1. When indoor air temperature is 35°C or more, the maximum power will be limited up to the rated power.2. When fan speed is set at “Lo” and intake air temperature is below 21°C, the maximum power will be limited up to the ratedpower.36CS-E9EKEB CU-E9EKEB / CS-E12EKEB CU-E12EKEB
