2.3. 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 •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). 6 CS-W7DKR CU-W7DKR / CS-W9DKR CU-W9DKR / CS-W12DKR CU- W12DKR
