4. Night Setback Mode

Night Setback Mode is used for saving energy.

Press the NIGHT SETBACK button while unit is operating.

The mark appears in the display.

To release the night setback function, press the NIGHT SETBACK button again.

In Cooling and DRY Mode: ( and )

When the night setback mode is selected, the air conditioner automatically raises the temperature setting 2 °F when 30 minutes have passed after the selection was made, and then another 2 °F after another 30 minutes have passed, regardless of the indoor temperature when night setback was selected. This enables you to save energy without sacrificing comfort. This function is convenient when gentle cooling is needed.

5. HIGH POWER Mode

HIGH POWER mode can be used to increase the output of the indoor unit for all operation modes.

Press the HIGH POWER button while unit is operating.

The mark appears in the display.

To cancel, press HIGH POWER button again.

When the HIGH POWER button is pressed, the unit operates at maximum output for 30 minutes, regardless of the desired temperature. The fan speed is 1 step above “High”.

NOTE

Depending on the operating conditions, the fan speed may be increased by a small amount only.

SPECIAL REMARKS

‘‘DRY’’ ( ) Operation

How it works?

Once the room temperature reaches the level that was set, the unit’s operation frequency is changed automatically.

During DRY operation, the fan speed automatically runs at lower speed for providing a comfortable breeze.

‘‘DRY’’ operation is not possible if the indoor temperature is 59 °F or less.

Cooling () operation

Sometimes the indoor unit may not get to the set fan speed such as LOW under cool operation at very low outdoor temperatures due to the indoor unit being protected from ice or frost when combined with the outdoor unit for Low Ambient Cooling models.

Power failure during operation

In the event of power failure, the unit will stop. When the power is resumed, the unit will restart automatically in approximately

5 minutes by the remote controller.

Clicking Sound

Clicking sound is heard from the air conditioner

In cooling operation, any plastic parts may shrink due to a sudden temperature change. In this event, a clicking sound may occur. This is normal, and the sound will soon disappear.

Remote Controller

The remote controller sends the setting condition to the air conditioner regularly at five minute intervals.

SETTING THE TIMER

NOTE

In the descriptions below, the following settings are used for the temperature and time indicator selector button on the bottom front section of the remote controller.

R410A specifications

Panasonic R410A is a refrigerant that has gained significant popularity in the air conditioning and refrigeration industry due to its favorable environmental properties and performance characteristics. Specifically designed to replace the harmful R22 refrigerant, which is being phased out due to its ozone-depleting potential, R410A offers a more eco-friendly alternative without compromising on efficiency or power.

One of the main features of R410A is its high energy efficiency. It operates at a higher pressure than R22, resulting in better heat transfer capabilities. This increased efficiency translates to lower energy consumption, making units using R410A more cost-effective in the long run. Additionally, R410A is known for its ability to provide excellent cooling performance even in high-temperature environments, making it suitable for a variety of applications, from residential air conditioning systems to commercial refrigeration units.

In terms of composition, R410A is a blend of two hydrofluorocarbons (HFCs), namely R32 and R125. This combination not only minimizes ozone depletion potential (ODP) but also reduces global warming potential (GWP) compared to older refrigerants. Panasonic has emphasized the importance of innovative technologies in its products, and R410A aligns perfectly with the company's commitment to developing sustainable solutions.

Panasonic also integrates advanced technologies to optimize the performance of R410A systems. For example, variable speed compressors, known as inverter technology, enhance system efficiency by adjusting the compressor's speed according to the cooling demand. This ensures that energy is only consumed when needed, further reducing operational costs.

Furthermore, R410A has a wide range of applications, including air conditioning systems, heat pumps, and chillers. Its versatility makes it a popular choice among manufacturers and consumers alike. The refrigerant is also compatible with existing R22 equipment, although specific retrofit procedures must be followed to ensure peak performance and reliability.

In conclusion, Panasonic R410A stands out as an innovative refrigerant choice in the HVAC industry, offering a combination of energy efficiency, environmentally friendly properties, and advanced technologies. As regulatory frameworks continue to tighten on greenhouse gas emissions, R410A and similar refrigerants are expected to play a crucial role in shaping a more sustainable future for air conditioning and refrigeration. Its high performance and lower environmental impact solidify its position as a leading refrigerant in contemporary cooling solutions.
