Anti-reverse Protection

To protect the compressor from reverse

rotation when power off suddenly.

Overload Protector

The 2-step Overload Protector is to protect

the compressor when

1)Temperature of compressor reaches 150

(PA7DKD,PC7DKD,PA9DKD) or

(PC9DKD)

2)High temperature or current enters into the

compressor

60-seconds Test Operation Control

Once the compressor is activated, it does not

stop for 60 seconds. It stops immediately with

remote control ON/OFF button.

Overload Protection Control

(For PA7DKD,PA9DKD only)

When the temperature of evaporator reaches 51 ,outdoor fan stops,and will restart when the temperature of evaporator declines to 49 . When the temperature of evaporator reaches 65 ,compressor will stop.

4-way Valve Control

(Only for PA7DKD,PA9DKD)

If the unit is stopped during Heating

Operation,the 4-way valve will remain in

heating mode operation for 5 minutes.

Deicing Control

Anti-freezing operation for outdoor unit(during

Heating Mode Operation only)

Temperature of the condenser is tested by TRS.

8 Operation Details

8.1 .Cooling Mode Operation

When selecting the Cooling Mode Operation, the unit will operate according to the setting by the Remote Controller or the control panel on the indoor unit and the operation is as the following.

Time Delay Safety Control

3 min.----If the compressor stops, it will not restart within 3 minutes.(Protection of compressor).

7 Minutes Time Save Control

7 min.----The unit will automatically operate in 7 minutes even if the room temperature is not reached. (Prevention of raising the humidity)

Anti-Freezing Control

If temperature of evaporator is lower than 2 continuously

Evaporator Temperature

()

for 4 minutes, the compressor will cease to prevent the evaporator from freezing. Fan speed setting will not be changed. When temperature of evaporator reaches 10 ,compressor will restart.

During Cooling Mode Operation, the Time Delay Safety Control is available.

Time

Automatic Fan Speed Mode
