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.
