CS-W12CTP CU-W12CTP5 / CS-W18CTP CU-W18CTP5 / CS-W24CTP CU-W24CTP5

Outdoor Unit

CU-W12CTP5

• 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 for W12CT

only.

Inner protector for W18CT & W24CT only.

Compressor Reverse Rotation

Protection Control

Outdoor Fan Operation Control

W18 / 24CT

• 4-pole induction motor (2 speed).

• For Cooling or Soft Dry operation

Hi-speed ............... When outdoor

temperature reaches to 31°C.

Lo-speed .............. When outdoor

temperature reaches to 29°C.

• For Heating operation

Hi-speed ............... When outdoor

temperature reaches to 13.5°C.

Lo-speed .............. When outdoor

temperature reaches to 15.5°C.

• For Over-heating Protection, the Fan is

switched ON or OFF depending on the

piping temperature and the outdoor

temperature.

W12CT

• 6-pole induction motor (1 speed).

CU-W18CTP5

CU-W24CTP5

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 (W12CT).

• Compressor stop when indoor heat

exchanger temperature reaches 65°C

(W12CT), 68°C (W18CT & W24CT).

(Heating Operation Only)

Deice Control

• To prevent frosting at outdoor heat ex-

changer. (Only for Heating Operation)

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).
