2. Protection of the evaporator pipe from frosting
• If the indoor pipe temperaure is below 0°C in 7 min. after the compressor operates without pause while in
cooling cycle operation mode,
➔
compressor, outdoor fan are turned off.
• When indoor pipe temp. is 7°C or higher after 2 min pause of compressor
➔
compressor, outdoor fan is turned on according to the condition of the room temperature.
3. Protection of the indoor fan from droplet formation (Enclosure
sweat and condensed disposal test)
• Control condition : The system operates standard operation without this condition as follows.
- Setting temperature <25°C
- Indoor fan speed
- Indoor fan speed
≤
low speed
- Outdoor temperature < 31°C
• Control method
- Operation frequency of compressor must be below
➃
(refer to the comp. Freq. table)
- The indoor fan operates at medium speed.

4. Cooling mode operation
• Operating frequency of compressor depend on the difference of the temperature.
(= intake air Temp.- Compressor off Temp.
• Compressor off temp.= setting temp. -0.5°C
on temp. = setting temp. +0.5°C
• If compressor operates at some operating frequency, the operating frequency of compressor cannot be
changed within 30 seconds.
• Condition of compressor turned off
- When intake air temperature stay at the temperature between setting temp. -0.5°C and setting temp.
-1.0°C for 3 minutes continuously.
- When intake air temperature reaches below the temperature of setting temp. -1.0°C.
• Compressor 2 minutes delay
- The compressor can restart minimum 2 minutes later after compressor off.

5. Healthy Dehumidification mode operation
• When the dehumidification operation is set by the remote controller the intake air temperature is detected and
the setting temp. is automatically set according to the intake air temperature.
• Operating frequency of compressor and indoor fan speed.

6. Heating mode operation
• Operating frequency of compressor depend on the difference of the temperature
(= compressor off temp. - intake air temp.)
• Compressor off temp. = setting temp.+3.0°C
on temp. = setting temp.
• If compressor operates at some operation frequency, the operating frequency of compressor cannot be
changed within 30 seconds.
• Condition of compressor turned off
- When intake air temperature reaches +3°C above the setting temperature.
• Condition of indoor fan turned off
- While in compressor on:indoor pipe temp. < 26°C
off: indoor pipe temp. < 37°C
• While in defrost control, between the indoor and outdoor fans are turned off.
• Compressor 2minutes delay
• Compressor 2minutes delay
- After compressor off, the compressor can restart minimum 2 minutes later.
