Indoor Unit Random Auto Restart Control •Operation is restarted randomly after power failure at previous setting mode. Anti-Freezing Control •Anti-Freezing control for indoor heat exchanger. (Cooling and Soft Dry) Ionizer Control •Ionizer control for generate negative ion in discharge air. Indoor Fan Speed Control •High, Medium and Low. •Automatic Fan Speed Mode –Heating : Fan speed varies from Me → SSLo in accordance with indoor heat exchanger. –Cooling : Fan rotates at Hi, Me and SLo speed. Deodorizing control is available. –Soft Dry : Fan rotates at Lo- speed. Deodorizing control is available. •Automatic air swing and manual adjusted by remote control for vertical airflow. •Manually adjusted by hand for horizontal airflow. Airflow Direction Control Automatic Operation Button •Press for < 5s to operate Automatic operation mode. (Used when the remote control cannot be used.) •Press continuously for 5s or < 10s to operate Test Run/Pump down. “Beep” sound will be heard at the 5th second. (Used when test running or servicing.) •Press continuously for 10s and above to omit or resume the remote control signal receiving sound. “Beep, beep” sound will be heard at the 10th second. AUTO OFF / ON Operation Indication Lamps (LED) •POWER (Green) ......... Lights up in operation, blinks in Automatic Operation Mode judging. •QUIET (Orange) .........

Lights up in Ionizer Mode Operation. Operation Mode •Heating, Cooling, Soft Dry and Automatic Mode. Powerful Operation •Reaches the desired room temperature quickly. Time Delay Safety Control •Restarting is inhibited for appro. 3 minutes. Starting Current Control Quiet Operation •To provide extra quiet operation. 7 Minutes Time Save Control •Cooling Operation only. •Fan motor is delayed for 1.6 seconds when compressor starts simultaneously. 30 Minutes Time Save Control •Heating Operation only. Hot-Start Control •At Heating Operation the indoor fan will operate at SLo speed when indoor heat exchanger temperature reaches 30°C. Anti Cold Draft Control •The indoor fan operates at SSLo when the indoor heat exchanger temperature is low. (During Heating mode thermal off) 4 CS-W7CKP CU-W7CKP 5 / CS-W9CKP CU-W9CKP 5 / CS-W12CKP CU-W12CKP5
Outdoor Unit •To protect compressor from reverse rotation when there is a instantaneous power failure. 60 Secs. Forced Operation Control •Once the compressor is activated, it does not stop within the first 60 secs. However, it stops immediately with remote control stop signal. Overload Protector •2-Stage OLP to protect the compressor. Overload Protector will trip when – Temperature of compressor increases to 120°C. – High temperature or high current flows to compressor. (Refer circuit diagram for OLP characteristic) Compressor Reverse Rotation Protection Control Outdoor Fan Operation Control •Temperature Fuse. 4-Way Valve Control •When the unit is switched to “OFF” during Heating Operation, 4-way valve stays at Heating position for 5 minutes. Overload Protection Control •Outdoor fan stops when indoor heat exchanger temperature rises to 51°C and above, and restarts when the indoor heat exchanger temperature drops to 49°C and below. •Compressor stop when indoor heat exchanger temperature reaches 65°C or above. (Heating Operation Only) Deice Control •To prevent frosting at outdoor heat exchanger. (Only for Heating Operation) • Temperature of outdoor heat exchanger is sensed by TRS (Thermal Reed Switch). TRS OFF temperature 4°C. TRS ON temperature -3°C. Compressor Protection Control •If the outdoor fan motor is not running after compressor starts for 50 secs., compressor will stop. (Cooling and Soft Dry Operation only). 5 CS-W7CKP CU-W7CKP 5 / CS-W9CKP CU-W9CKP 5 / CS-W12CKP CU-W12CKP5
