8 Operation Details

8.1. Cooling Mode Operation

Cooling in operation according to Remote Control setting.

Time Delay Safety Control (3 minutes)

• When the compressor is stopped by Remote Control, it restarts after 3 minutes when it is turned ON by Remote Control.

• When the setting temperature is reached during cooling operation, the compressor stops and it will not start for 3 minutes.

7 minutes Time Save Control

• The compressor will start automatically if it has stopped for 7 minutes even if the room temperature is between the compressor

ON temperature and OFF temperature.

Starting Current Control

• When the compressor outdoor fan motor and indoor fan motor are simultaneously started, the indoor fan motor will operate 1.6

second later.

Anti-Freezing Control

• If the temperature of the indoor heat exchanger falls

continuously below 2°C for 4 minutes or more, the compressor turns off to protect the indoor heat exchanger from freezing. The fan speed setting remains the same.

• Compressor will restart again when the indoor heat

exchanger temperature rises to 10°C (Recovery).

3 minutes waiting of Time Delay Safety Control is valid for Cooling Operation.

Compressor Reverse Rotation Protection Control

• If the compressor is operating continuously for 5 minutes or longer and the temperature difference between intake air and

indoor heat exchanger is 2.5°C or less for 2 minutes, compressor will stop and restart automatically. (Time Delay Safety Control is valid)

s T = Intake air temperature - Indoor heat exchanger temperature This is to protect reverse rotation of the compressor when there is a instantaneous power failure.

CS-A7BKP CU-A7BKP5 / CS-A7BKP CU-A7B KP6 / CS-A9BKP CU-A9BKP5 / CS-A9BKP CU-A9B KP6 / CS-A12BKP CU-A12BKP5 / CS-A12BKP CU-A12BKP6

Compressor Protection Control

• After the compressor starts for 50 seconds but the outdoor fan motor is still OFF, the compressor will stop and restart

automatically. (Time Delay Safety Control is valid).

• If the above phenomenon is repeated for 3 times, the compressor will stop totally.

• The above phenomenon is reset when there is a change to heating mode or stopped by Remote Control Switch.

Anti-Dew Formation Control

• Purpose is to prevent dew formation on indoor unit air discharge area.

• When the following conditions occur for 30 minutes continuously, anti-dew formation is controlled by indoor fan speed shift to

low (CLo to HLo):

− Indoor intake air temperature is more than 24°C and less than 30°C.

− Remote Control setting temperature is less than 25°C.

− Compressor is on.

− Cooling operation mode.

− Indoor Fan motor operate at Low fan speed.

• This control is cancelled immediately when above condition is changed.

Automatic Fan Speed Mode

When Automatic Fan Speed is selected at Remote Control during cooling operation.

• Fan speed rotates in the range of Hi to Me.

• Deodorizing Control.

then Soft Dry operation will start.

• During Soft Dry operation, the Indoor Fan will operate at SLo speed.

• The operation will be switched on and off for up to 10 minutes “ON” and 6 minutes “OFF”. Once Soft Dry operation is turned

off, it stops for 6 minutes.

Time Delay Safety Control

• Once the compressor stops, it will not start for 3 minutes during Cooling operation.

Starting Current Control

• Same as Starting Current Control for Cooling Mode operation.

Anti-Freezing Control

• Same as Anti-Freezing Control for Cooling Mode operation. (For Soft Dry region, 6 minutes waiting is valid during compressor

stops.)

Compressor Reverse Rotation Protection Control

• Same as Compressor Reverse Rotation Protection Control for Cooling Mode Operation. (For Soft Dry region, 6 minutes waiting

is valid during compressor stops.)

Compressor Protection Control

• Same as Compressor Protection Control for Cooling Mode Operation.

Anti-Dew Formation Control

• Same as Anti-Dew Formation Control for Cooling Mode Operation.

Automatic Fan Speed Mode

When Automatic Fan Speed is selected at Remote Control during Soft Dry operation.

8.3. Heating Mode Operation

Heating in operation according to Remote Control setting.

Time Delay Safety Control

• When the compressor is stopped by Remote Control, it restarts after 3 minutes when the Remote Control is turned ON.

• When the setting temperature is reached during heating operation, the compressor stops and it will not start for 4 minutes.

30 minutes Time Save Control

• The compressor will start automatically if it has stopped for 30 minutes even if the room temperature is between the compressor

ON temperature and OFF temperature.

Overload Protection Control

(a) Outdoor Fan Control

• If the temperature of the indoor heat exchanger rises to 51°C, Outdoor Fan stops.

The Outdoor Fan restarts when the indoor heat exchanger temperature falls to 49°C.

(b) Compressor high pressure protection

• If the indoor heat exchanger becomes 65°C or more, the compressor will stop and restart automatically.

(Time Delay Safety Control - 4 minutes waiting).

Compressor Reverse Rotation Protection Control

• If the compressor is operating continuously for 5 minutes or longer and temperature difference between intake air and indoor

heat exchanger is 5°C or less for 2 minutes, compressor will stop and restart automatically.

(Time Delay Safety Control is valid).

s T = Indoor heat exchanger temperature - intake air temperature. This is to protect reverse rotation of the compressor when there is a instantaneous power failure.

4-way Valve Control

• 4-way valve always ON during Heating operation. (Except Deicing operation)

• When the unit is switched to “OFF” during Heating operation, 4-way valve stay at Heating position for 5 minutes.

Outdoor Fan Motor Control

• When compressor stops (reaches room temperature), outdoor fan will operate for 30 seconds.

(30 seconds Forced Operation).

Indoor Fan Motor Control

• When compressor stops (reaches room temperature), indoor fan will stop for 1 minutes, operate for 3 minutes, if still not yet

reaches the room temperature, indoor fan Lo- for 40 sec. after that operate at SLo speed.

Hot Start Control

When Heating operation starts, Indoor Fan will not start until the indoor heat exchanger reaches 30°C as diagram shown.

Hot Start is completed when indoor heat exchanger rises to 39°C or over 4 minutes.

Anti Cold Draft Control

• This operation is to prevent the Cold Draft during Heating mode operation.

• The operation will start when compressor OFF (Thermo OFF) during Heating operation.

• For the first 30 sec. from compressor OFF (Thermo OFF), Indoor fan speed will operate accordingly to the Indoor heat

exchanger temperature as shown below:

• After 30 sec. from compressor OFF (thermo OFF), Indoor fan will run at SSLo speed only.

• Anti Cold Draft Control will stop when:

− Intake temperature < set temperature. (Time Delay Safety Control 4 minutes waiting is valid)

− After 30 minutes time saved control.

(see page 24).

Deicing Control

Deice starts to prevent frosting at outdoor heat exchanger.

• Normal Deicing

Deice operations detection commences after 30 minutes of Heating operation starts or 60 minutes after previous deice operation. If the TRS (Thermal Reed Switch) senses the outdoor piping temperature drops to -3°C (TRS CLOSE) or less for 50 sec. continuously during compressor is in operation, deice will start.

(There is no detection during Outdoor Fan stops.)

• Overload Deicing

During heating operation, if the outdoor Fan OFF duration (due to overload control) is accumulated up to 60 minutes and after compressor starts for 1 minutes, deicing starts.

• Deicing ends when

1. 12 minutes after deicing operation starts;

2. TRS senses the outdoor piping temperature rises to 4°C (TRS OPEN).

3. Deicing will not end immediately as time delay (Td) is valid as shown below.

• Once deicing operation starts, it will not end for 60 seconds.

• After deicing operation, compressor stops for 30 seconds and 4-way valve stays at cooling position for 10 seconds.
