CS-MA95KE CU-MA185KE / CS-MA125KE CU-MA245KE / CS-MA75KE / CS-MA125KE CU-MA195KE

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.

(Refer circuit diagram for OLP

characteristic)

Compressor Reverse Rotation

Protection Control

Outdoor Fan Operation Control

•Inner protector.

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).
