7 Operation Details
7.1. Cooling Mode Operation
•
•
When selecting the Cooling Mode Operation, the unit will operate according to the setting by the Remote Control and the
• •
operation is as the following.
Time Delay Safety Control
•
•
3 min. ---- The compressor is ceased for 3 minutes to balance the pressure in the refrigeration cycle.
• •
•
•
(Protection of compressor).
• •
Automatic Restarting Control
•
•
7 min. ---- The unit will automatically operate in 7 minutes even if the room temperature is not reached.
• •
(Prevention of raising the humidity)
Anti-freezing Control
•
•
If temperature of evaporator is lower than 2°C continuously
• •
for 4 minutes, the compressor will cease to prevent the
evaporator from freezing. Fan speed setting will not be
changed.
•
•
When temperature of evaporator reaches 10°C,
• •
compressor will restart.
During Cooling Mode Operation, the Time Delay Safety Control
is available.
Anti-reversing Control
•
•
If the compressor has been continuously running for 5 minutes, and the difference of temperature between intake air and
• •
evaporator is continuously lower than 2.5°C for 2 minutes, the compressor is ceased for 3 minutes then restarts. (Time Delay
Protection Control is effective.)
15
CS-PC9CKV CU-PC9CKV / CS-PC12CKV CU-PC12C KV
Automatic Fan Speed Mode
During Cooling Mode Operation, use remote control to select Automatic Fan Speed.
•
•
Fan speed will be at the point between "high speed" and "medium speed".
• •
•
•
Deodorization control.
• •
Time Graph for cooling Operation
16
CS-PC9CKV CU-PC9CKV / CS-PC12CKV CU-PC12C KV
7.2. Soft Dry Mode Operation
•
•
When selecting Soft Dry mode operation, the operation will be cooling until the room temperature reaches the set temp on the
• •
remote control, and then Soft Dry will be activated. (During Soft Dry Mode the fan of indoor unit will operate at super low speed.)
•
•
Once soft Dry mode operation is turned off, indoor fan, compressor and outdoor fan will stop for 6 minutes.
• •
Time Delay Safety Protection
•
•
During cooling mode operation, if the compressor ceased, it will not restart within 3 minutes.
• •
Anti Freezing Control
•
•
Same as the denotation in Cooling Operation. (P.15)
• •
(During Soft Dry Mode Operation, compressor will stop for at least 6 min.)
Anti-reverse Control
•
•
Same as the denotation in Cooling Operation. (P.15)
• •
Automatic Fan Speed
During Soft Dry Operation, use remote control to select Auto Fan Speed mode.
•
•
Indoor Fan Speed is at super low.
• •
•
•
Deodorization control.
• •

7.3. Automatic Mode Operation
Standard for determining operation mode
First Determination:
Second Determination:
One hour after the above determination, the unit will operate according to the table below.
CS-PC9CKV CU-PC9CKV / CS-PC12CKV CU-PC12C KV
1. Indoor fan operates at super low speed for 20 seconds.
2. After judging indoor air temperature, the operation is determined and operation continued at the mode determined.
3. After the operation mode has been determined, the mode does not change. However, Soft Dry mode operation includes cooling
mode operation.
4. If automatic mode operation is started while the unit is operating, operation will continue.
If current operation is in cooling mode (including the cooling mode operation when is a part of Soft Dry mode operation) it will
be maintained, and if current operation is not cooling mode, the appropriate operation mode is determined for 20 seconds at
super slow fan speed. Then the selected mode will continue.
5. Room temperature adjustment
