ON/OFF operation button

This button is for turning the air conditioner on and off.

MODE selector button

Use this button to select AUTO, HEAT, DRY, COOL or FAN mode.

(AUTO)

: When this setting is selected, the air conditioner calculates the difference between the

 

thermostat setting and the room temperature and automatically switches to the ‘‘COOL’’ or

 

‘‘HEAT’’ mode as appropriate. (This function is available only for “Single use” of COOL/DRY/

 

HEAT Model.)

(HEAT)

: The air conditioner makes the room warmer.

(DRY)

: The air conditioner reduces the humidity in the room.

(COOL)

: The air conditioner makes the room cooler.

(FAN)

: The air conditioner works only as a circulation fan except for “Multiple use” of COOL/DRY/

 

HEAT Model.

1 HR. TIMER button (1-HOUR OFF TIMER)

: When you press this button, regardless of whether the unit is operating or stopping, the unit operates for one hour and then shuts down.

TIMER SELECT button

No display : The timer does not operate.

: The air conditioner starts at the set time.

: The air conditioner stops at the set time.

: The air conditioner stops and starts, or starts and stops, at the set times every day.

Sensor

A temperature sensor inside the remote controller senses the room temperature.

SENSOR button

When you press this button (use a small-tipped object such as a ballpoint pen), the mark will disappear at the display. And the room temperature is detected by the sensor which is built into the remote controller and the air conditioner is controlled accordingly.

NOTE

If the remote controller is located near a heat source, such as a space heater or in direct sunlight, press the SENSOR button to switch to the sensor on the indoor unit.

NOTE

The indoor fan runs continuously when the system is in normal operation. It does not turn off when the desired room temperature is reached. If Night Set Back mode is selected, the fan will turn off intermittently during cooling operation in order to control air flow.

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.
