Outdoor Unit
• To protect compressor from reverse
rotation when there is a instantaneous
power failure.
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.
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
– Temperature of compressor increases
to 120°C.
– High temperature or high current flows
to compressor.
