Compressor Reverse Rotation
Protection Control
Outdoor Unit
Functions
• To protect compressor from reverse
rotation when there is a instantaneous
power failure.
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)
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.
Outdoor Fan Operation Control
•
Inner protector.
CU-A123KE
CU-A73KE, CU-A93KE
Deice Control
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 ex-
changer temperature reaches 65°C or
above. (Heating Operation Only)
4-Way Valve Control
• When the unit is switched to "OFF" during
Heating Operation, 4-way valve stays at
Heating position for 5 minutes.
Outdoor Fan Motor Control
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).
• To prevent frosting at outdoor heat
exchanger. (Only for Heating Operation)
•
Temperature of outdoor heat exchanger is
sensed by TRS (Thermal Reed Switch).
