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).
