Time Delay Safety Control
7-minutes Time Save Control
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.
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.
•
• •
• 3 min. ---- The compressor is ceased for 3 minutes to balance the pressure in the refrigeration cycle.
•
• •
• (Protection of compressor).
•
• •
• 7 min. ---- The unit will automatically operate in 7 minutes even if the room temperature is not reached.
(Prevention of raising the humidity)

Automatic Fan Speed Mode
Time Graph for cooling Operation
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.

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.
•
• •
• During cooling mode operation, if the compressor ceased, it will not restart within 3 minutes.
•
• •
• Same as the denotation in Cooling Operation. (P.12)
During Soft Dry Operation, use remote control to select Auto Fan Speed mode.
•
• •
• Indoor Fan Speed is at super low.
•
• •
• Deodorization control.

Warm booting control
•
• •
• When turning on the unit by heating mode operation, indoor
fan will be activated when temperature of indoor heat
exchanger reaches 30°C.
•
• •
• Warm booting operation ends when temperature of indoor
heat exchanger reaches 34 °C.
•
• •
• During warm booting or within 3 minutes after the ending
the Ry-C will not turn off.
7.3. Heating Mode Operation
When selecting heating mode operation, the unit will operate according to the setting by the remote control.
•
• •
• If the compressor stopped by switching off,turning off by remote control, or power off, it will not restart within 3 minutes.
•
• •
• When room temperature reaches the set temperature on the remote control, compressor stops and will not restart within 4
minutes.
•
• •
• 3 minutes after the compressor stopped, indoor fan will stop for 1 minute. Then indoor fan will resume operation with the speed
at "super low".
•
• •
• Same as the denotation in Cooling Operation.(P.12)
•
• •
• When temperature of indoor heat exchanger rises to 51°C, outdoor fan will stop when temperature of indoor heat exchanger
falls to 49°C, outdoor fan will restart.
•
• •
• When temperature of indoor heat exchanger rises to 65°C or above, compressor stops, and will restart 4 minutes later.
•
• •
• During heating mode operation, 4-way valve is at "open" mode.
•
• •
• During heating mode operation, if the unit turned off , the 4-way valve will remain at "open" mode for 5 minutes.

Automatic Fan mode operation
Time graph for heating mode operation
When selecting automatic fan mode by remote control during heating mode operation, the fan will operate at different speed
under different conditions according to the temperature of indoor heat exchanger.

CS-SA18CKP / CU-SA18CKP5

Deice Control
Deice operation is to protect the outdoor unit from freezing.
•
• •
• Normal Deice Operation
Deicing starts 60 minutes after heating mode operation or 60 minutes after the latest deicing operation. If temperature of
outdoor piping, tested by TRS, falls to -4°C (TRS OFF) or below for continuously 50 seconds, deicing operation starts.
•
• •
• Overload Deicing Operation
During heating operation,if the accumulative stopping time of outdoor fan reaches 60 minutes, deicing operation will start 1
minute after compressor starts.
•
• •
• Deicing operation ends under conditions below
1. After 12 minutes.
2. Temperature of outdoor unit rises to 4 °C.
Notes:
When deicing operation ends, compressor will stop for 30 seconds, and 4-way valve remains at cooling mode operation for 10
seconds.

Standard for determining operation mode
7.4. Automatic Mode Operation
First Determination:
1. Indoor fan operates at super low speed for 25 seconds.
2. After judging indoor air temperature,the operation is determined and operation continued at the mode determined.
3. If indoor temperature is less than 16°C, heating operation will immediately operate.
4. After the operation mode has been determined,the mode does not change. However, Soft Dry mode operation includes cooling
mode operation.
5. Room temperature adjustment
7.5. Indoor Fan Motor Control
•
• •
• Automatic fan speed control
When automatic fan speed set,the available range for fan speed is from H to SLo
•
• •
• Manual Fan Speed Control
•
• •
• Basic fan speed can be manually adjusted (Lo, Med,Hi) by using the fan speed selection button.
