							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, (XC9CK).
• Inner Overload Protector (XC12CK).
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.
