OPERATION

Room temperature sensor selection

Indoor unit

Press the ECONOMY button for more than 2 seconds to se- lect whether the room temperature is detected at the indoor unit (remote sensor) or the remote controller.

When the thermo sensor display appears, the room temperature is detected at the remote controller.

NOTES

•This function is locked at the factory. In order to detect the room temperature correctly, consult authorized service personnel when using this function.

•If this function is locked, the location where the room temperature is detected cannot be changed and the mark flashes when the ECONOMY button is pushed for 2 seconds or more.

Child lock function

Press the DAY (DAY OFF) button and SET button simul- taneously for 2 seconds or more to activate the child lock function and lock all buttons on the remote controller. Press the buttons again for 2 seconds or more to deacti- vate the child lock function.

When the child lock function is activated, the mark appears. If any button is pressed during the child lock, the

R410A specifications

Fujitsu R410A is a state-of-the-art refrigerant commonly used in air conditioning systems and heat pumps. Recognized for its superior thermal efficiency and environmental considerations, R410A has become a popular choice among manufacturers and consumers alike.

One of the standout features of Fujitsu R410A is its high energy efficiency. This refrigerant operates on a higher pressure than traditional refrigerants like R22, which allows for better heat exchange and thus improves the overall performance of HVAC units. The efficiency is evident in both cooling and heating capacities, which contributes to reduced energy costs for end users. As energy efficiency becomes increasingly important, R410A meets the demands of modern consumers looking for sustainable solutions without sacrificing comfort.

Fujitsu incorporates advanced technologies in their R410A systems to enhance performance further. The variable speed inverter technology found in many Fujitsu air conditioning systems allows for more precise temperature control and improved efficiency. By adjusting the compressor speed according to the cooling or heating demand, these systems can operate at a lower capacity when required, reducing energy consumption and maintaining indoor comfort more effectively.

Another characteristic of Fujitsu R410A is its low global warming potential (GWP). While traditional refrigerants have raised concerns about their impact on climate change, R410A has a significantly lower GWP, making it a more environmentally friendly option. The use of R410A helps meet international regulations aimed at reducing greenhouse gas emissions, positioning it as a sustainable choice in the HVAC industry.

Additionally, Fujitsu units utilizing R410A are known for their quiet operation. Advances in design and engineering minimize noise levels, contributing to a more pleasant indoor environment. Noise-reduction technologies, combined with efficient airflow management, ensure that users can enjoy comfort without disruptive sounds.

Furthermore, Fujitsu provides robust support and maintenance services for R410A systems, ensuring optimal performance over their lifespan. Their commitment to reliability is reflected in the build quality and design of the units, which are engineered for longevity and dependability.

In summary, Fujitsu R410A is a premium refrigerant characterized by high energy efficiency, advanced inverter technology, low global warming potential, and quiet operation. These features make it a preferred choice for modern air conditioning and heating solutions, affirming Fujitsu's commitment to innovation in the HVAC industry while prioritizing environmental responsibility.
