Frequently Asked Questions - CS-A28PKD PANASONIC

How to use the ECONAVI function to save energy?

The ECONAVI function automatically adjusts the temperature based on human presence and activity, as well as sunlight intensity. To activate it, press the ECONAVI button on the remote control. The indicator lights up. The human activity sensor scans the room and the sunlight sensor detects solar radiation to optimize energy consumption.

How to clean the air filters?

Open the front panel, remove the air filters. Gently wash them with clean water (temperature below 40 °C) without harsh detergent. Dry them completely in the shade before reinstalling. It is recommended to clean the filters every 2 weeks under normal use.

What is nanoe-G technology and how does it work?

The nanoe-G is an ion generator that deactivates harmful microorganisms (viruses, bacteria) in the air and on the filter. It starts automatically when the unit is powered on. You can also activate filter disinfection after the unit stops by holding down the appropriate button.

How to set the timer so that the unit stops or starts at a specific time?

On the remote control, press TIMER to select the ON or OFF mode. Set the desired time using the + and - buttons, then confirm with SET. The timer operation repeats daily. To cancel, press CANCEL.

Why does water or steam come out of the outdoor unit?

This is normal: water condenses or evaporates in the pipes during operation. In heating mode, frost may form and melt, producing water. This is not a malfunction.

What to do if the remote control does not work?

First check the batteries: insert new AAA/R03 batteries observing polarity. Make sure the receiver on the indoor unit is not obstructed. If the display is dim, replace the batteries. Some fluorescent lights may interfere; move them away.

How to activate the Powerful (POWERFUL) mode?

Press the POWERFUL button on the remote control. The unit will operate at full power for 15 minutes to quickly reach the desired temperature, then automatically return to normal mode.

Why does the indoor unit make a cracking sound?

Temperature variations cause expansion and contraction of materials. This cracking sound is completely normal and does not require any action.

How to adjust the airflow direction?

Use the remote control to change the flap direction: press the SWING button for automatic oscillation or the direction buttons for manual adjustment. Never move the flap manually to avoid damage.

When to call a professional for repair?

Contact an authorized dealer if you hear abnormal noises, if water enters the unit, if the circuit breaker trips frequently, if the power cord is hot, or if the buttons do not work. Never attempt to repair internal parts yourself.

Operation mode

HEAT: Unit takes a while to warm up. The POWER indicator blinks during this operation.

COOL: Use curtains to screen off sunlight and outdoor heat to reduce power consumption during COOL mode.

DRY: Unit operates at low fan speed to give a gentle cooling operation.

nanoe-G in-fi lter deactivation

Depending on the unit's accumulated operation time, nanoe-G in-filter deactivation may activate only once a day after the unit turned off.

To remove the moisture left in the internal parts, the fan will operate for 30 minutes with louver opened slightly. This process only applicable when the unit is operated in COOL/DRY mode before turned off. Then, nanoe-G deactivates viruses/bacteria on the filter for 2 hours with fan stopped and louver closed.

Do not turn off the power supply during this operation. After power failure, this operation will not resume.

AIR SWING

Note

When manual AIR SWING is selected, the ECONAVI and AUTO COMFORT operations will be cancelled.

Human activity sensor operation

ECONAVI; Detecting human presence and activity, the unit controls room temperature to save energy.

AUTO COMFORT; Detecting human presence and activity, the unit controls room temperature to keep human comfortable consistently.

• During low activity, fan speed 1 tap up for first 15 minutes or until set temperature is reached.
  ** During human absence, maximum fan speed for COOL/DRY mode is medium fan.

The human activity sensor will also scan for area of heat source and movement in a room.

Detection area Human activity indicator

At left area At center / multiple area At right area

The unit judges human activity area for a few seconds before indicator updates. Based on area activeness horizontal airflow direction louver will adjust either fix at predetermined position or swing left/right periodically.

The human activity sensor performance is influenced by indoor unit location, movement speed, temperature range, etc.
The human activity sensor may:

• mistakenly detect an object with heat source & movement similar to human, such as pets, etc.
• mistakenly detect as non-heat source & movement if a human stays motionless for certain period of time.
• Do not place large objects near the sensor and keep away heating units or humidifier from the sensor's detection area. They may cause sensor malfunction.

Sunlight Sensor operation

ECONAVI; Detecting sunlight intensity, the unit adjust temperature to save energy.

ECONAVI is activated, the unit maintains set temperature until a high sunlight intensity is detected. The sunlight sensor detects sunlight intensity during weather or day/night changes, and the unit adjusts temperature.

• In a room without window or with thick curtain, the sunlight sensor will judge as cloudy/night.

Troubleshooting

The following symptoms do not indicate malfunction.

Symptom Cause
Mist emerges from indoor unit. · Condensation	effect due to cooling process.
Water flowing sound during operation.	· Refrigerant flow inside the unit.
The room has a peculiar odour. · This may be due to damp smell emitted by the wall, carpet, furniture or clothing.
Indoor fan stops occasionally during automatic fan speed setting.	· This helps to remove the surrounding odour.
Operation is delayed a few minutes after restarting.	· The delay is a protection to the unit's compressor.
Outdoor unit emits water/steam. · Condensation	or evaporation occurs on pipes.
TIMER indicator is always on. · The timer setting	repeats daily once set.
POWER indicator blinks during operation and the indoor fan is stopped.	· The unit is in defrost mode, and the melted frost is drained from the outdoor unit.
Indoor fan stops occasionally during heating operation.	· To avoid unintended cooling effect.
Cracking sound during operation. · Changes of	temperature caused the expansion/contraction of the unit.
2 or more human activity indicator turns on simultaneously.	· Judgement of heat source and movement area in progress.

Check the following before calling for servicing.

Symptom Check
Operation in HEAT/COOL mode is not working effi cientsly.	• Set the temperature correctly. • Close all doors and windows. • Clean or replace the fi lters. • Clear any obstruction at the air inlet and air outlet vents.
Noisy during operation. • Check if the unit has been installed at an incline. • Close the front panel properly.
Remote control does not work. (Display is dim or transmission signal is weak.)	• Insert the batteries correctly. • Replace weak batteries.
The unit does not work. • Check if the circuit breaker is tripped. • Check if timers have been set.
The unit does not receive the signal from the remote control.	• Make sure the receiver is not obstructed. • Certain fl fluorescent lights may interfere with signal transmitter. Please consult authorised dealer.

NON SERVICEABLE CRITERIAS

TURN OFF POWER SUPPLY AND UNPLUG then please consult authorised dealer under the following conditions:

Abnormal noise during operation.
Water/foreign particles have entered the remote control.
Water leaks from Indoor unit.

• Circuit breaker switches off frequently.
• Power cord becomes unnaturally warm.
• Switches or buttons are not functioning properly.
