Indoor Unit

AUTO OFF / ON

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.

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.

Starting Current Control
· Fan motor is delayed for 1.6 seconds when compressor starts simultaneously.

Operation Mode
· Heating, Cooling, Soft Dry and Automatic Mode.

Time Delay Safety Control
· Restarting is inhibited for appro. 3 minutes.

Powerful Operation
· Reaches the desired room temperature quickly.

7 Minutes Time Save Control
· Cooling Operation only.

30 Minutes Time Save Control Quiet Operation
· To provide extra quiet operation. · Heating Operation only.

Hot-Start Control Random Auto Restart Control
· Operation is restarted randomly after power failure at previous setting mode. · At Heating Operation the indoor fan will operate at SLo speed when indoor heat exchanger temperature reaches 30°C.

Outdoor Unit

Compressor Reverse Rotation Protection Control
· To protect compressor from reverse rotation when there is a instantaneous power failure.

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.

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)

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)

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.

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).

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.
