2. Stop by OFF/ON switch.

3. Timer off activates.

4. Quiet button is pressed again.

The control contents for Quiet operation in Cooling/Dry Mode for the PANASONIC CS-E10JD3EA Air Conditioner are:

3. Timer off activates.

4. Quiet button is pressed again.

The control contents for Quiet operation in Heating Mode for the PANASONIC CS-E10JD3EA Air Conditioner are:

When the powerful mode is selected on the PANASONIC CS-E10JD3EA Air Conditioner, the internal setting temperature will shift higher up to 3.5°C (for Heating) or lower up to 2°C (for Cooling/Soft Dry) than remote control setting temperature for 20 minutes to achieve the setting temperature quickly.

When the ON Timer is set using the remote control for the PANASONIC CS-E10JD3EA Air Conditioner, the unit with the timer set will start operating earlier than the setting time to provide a comfortable environment when reaching the set ON time. 60 minutes before the set time, the indoor fan motor (at fan speed of Lo-) and outdoor fan motor start operating for 30 seconds to determine the indoor intake air temperature and outdoor air temperature in order to judge the operation starting time.

When the OFF Timer is set using the remote control for the PANASONIC CS-E10JD3EA Air Conditioner, the unit will stop operating at the set time.

The Restart Control (Time Delay Safety Control) for all operations on the PANASONIC CS-E10JD3EA Air Conditioner is:

The Compressor will not turn on within 3 minutes from the moment operation stops, although the unit is turned on again by pressing the OFF/ON button at the remote control within this period. This control is not applicable if the power supply is cut off and on again. This phenomenon is to balance the pressure inside the refrigerant cycle.

The 30 Seconds Forced Operation protection on the PANASONIC CS-E10JD3EA Air Conditioner means that once the air conditioner is turned on, the compressor will not stop within 30 seconds in a normal operation although the intake air temperature has reached the thermo-off temperature. However, force stop by pressing the OFF/ON button at the remote control is permitted or the Auto OFF/ON button at the indoor unit. The reason is to allow the refrigerant oil run in a full cycle and return back to the outdoor unit.

The Total Running Current Control for the outdoor unit of the PANASONIC CS-E10JD3EA Air Conditioner is implemented as follows:

1. When the outdoor unit total running current (AC) exceeds X value, the frequency instructed for compressor operation will be decreased.

2. If the running current does not exceed X value for five seconds, the frequency instructed will be increased.

3. However, if total outdoor unit running current exceeds Y value, the compressor will be stopped immediately for 3 minutes.

The values for X (A) and Y (A) during the first 30 minutes of cooling operation (A) are:

The Overheating Prevention Control for the IPM (Power transistor) on the PANASONIC CS-E10JD3EA Air Conditioner is:

2. Compressor operation restarts after three minutes the temperature decreases to 95°C.

The DC Peak Current Control for the IPM (Power transistor) on the PANASONIC CS-E10JD3EA Air Conditioner is:

1. When electric current to IPM exceeds set value of 22.33 ± 5.0 A, the compressor will stop operate. Then, operation will restart after three minutes.

2. If the set value is exceeded again more than 30 seconds after the compressor starts, the operation will restart after two minutes.

3. If the set value is exceeded again within 30 seconds after the compressor starts, the operation will restart after one minute. If this condition repeats continuously for seven times, all indoor and outdoor relays will be cut off.

The instructed frequency for compressor operation on the PANASONIC CS-E10JD3EA Air Conditioner is regulated by compressor discharge temperature. If compressor discharge temperature exceeds 112°C, the compressor will stop, occurring 4 times per 20 minutes, and the timer LED will be blinking (“F97” is to be confirmed).

The compressor operating frequency on the PANASONIC CS-E10JD3EA Air Conditioner during Cooling & Soft Dry Operation is regulated in accordance to the outdoor air temperature, beginning 1 minute after the compressor starts. The compressor frequency will adjust based on Outdoor Air Temperature.

1. Detection of the Outdoor pipe temperature and applying restriction/limitation (Limit the compressor Operation frequency).

2. The compressor stopping if the outdoor pipe temperature exceeds 63°C.

The malfunction decision conditions for F11 (4-way valve Abnormality) on the PANASONIC CS-E10JD3EA Air Conditioner are:

1. When heating operation, when indoor pipe temperature is below 10°C.

2. When cooling operation, when indoor pipe temperature is above 45°C.

The malfunction causes for F11 (4-way valve Abnormality) on the PANASONIC CS-E10JD3EA Air Conditioner are:

1. Connector in poor contact.

2. Faulty sensor.

3. Faulty outdoor unit PCB.

4. 4-way valve defective.

The troubleshooting procedure when F11 indication happens on the PANASONIC CS-E10JD3EA Air Conditioner is:

1. Check the indoor pipe temperature sensor. If it does not conform to the sensor characteristic chart, replace the indoor pipe temperature sensor. If it conforms, check if the 4-way valve coil is energized during cooling operation. If it is energized, replace the outdoor unit PCB. If not energized, check harness out of connector. If harness is out of connector, reconnect the harness. If harness is connected, check the continuity of the 4-way valve coil. If there is no continuity, replace the 4-way valve coil. If there is continuity, disconnect the harness from the connector. Measure the resistance between harnesses. If resistance is about 18Ω, measure DC voltage supply to CN-HOT (pin1 & 2) during heating operation. If the voltage supply to 4-way valve is 2.5-4.5Vdc, replace the outdoor unit PCB. If not, replace the 4-way valve.

3. Faulty outdoor PCB.

The troubleshooting procedure when abnormality indication starts again for F90 (Power Factor Correction Protection) on the PANASONIC CS-E10JD3EA Air Conditioner is:

1. Check the supply voltage. If supply voltage is not as specified, correct the power supply.

2. If supply voltage is as specified, operate the system. Verify PFC abnormality by measuring DC voltage between P(+) and N(-) terminal at the outdoor unit PCB. If the DC voltage is not between 285-315Vdc, it is a defect in PFC circuitry or replace the outdoor unit PCB.

3. If the DC voltage is between 285-315Vdc, check the compressor winding resistance. Turn off the power supply and reconnect the harness U, V and W. Measure the winding resistance between U-V, V-W and W-U. If the compressor’s winding resistance (U-V, V-W, W-U) are not uniform, replace the compressor. If uniform, replace the outdoor unit PCB.
