Setup of external static pressure

•Select with shifting of the short plug on the indoor unit microcomputer P.C. board.

Matching with the resistance (External static pressure) of the duct to be connected, be sure to set up the tap exchange according to the basic operation procedure

(1 → 2 → 3 → 4 → 5 → 6 ).

•For the item code in Procedure 3, specify [5d].

•For the set data in Procedure 4, select the setup data of static pressure outside of the machine to be set up from the table below.

When mounting a filter sold separately, be sure to set up the tap exchange according to the type of filter.

In this case, also follow to the basic operation procedure (1 → 2 → 3 → 4 → 5 → 6 ).

When using wireless remote controller

To exchange the static pressure, there is a method other than the abovementioned method by wired remote controller, which is to shift the short plug on the indoor microcomputer P.C. board as shown in the following table. Adopt this method in case of using a wireless remote controller, etc.

*However, after exchanging once, be careful to shift the short plug to the standard position (At shipment) in order to return to the standard setup (follow to E2PROM setup) though the setup for high static- pressure 1, high static-pressure 2, or low static- pressure can be arbitrarily performed.

It is necessary to rewrite data from the wired remote controller sold separately in the set data “0000”.

*1 Resistance of high-performance filter 65 and 90, deodorant filter, or ammonia deodorizing filter is equivalent to 30Pa. Therefore, set the resistance (external static pressure) of a duct to be connected to 40Pa.

R410A specifications

Toshiba R410A is a highly regarded refrigerant known for its efficiency and environmental benefits. This hydrofluorocarbon (HFC) mixture is widely used in various air conditioning and refrigeration applications due to its excellent thermodynamic properties. One of the standout features of R410A is its superior energy efficiency, which contributes to lower energy consumption and reduced CO2 emissions in HVAC systems.

One significant advantage of R410A over older refrigerants, such as R22, is its lower ozone depletion potential (ODP). R410A has an ODP of zero, making it a more environmentally friendly choice. This characteristic aligns with global initiatives aimed at protecting the ozone layer and promoting sustainable practices. The shift to R410A has been supported by government regulations in many countries, phasing out older, more harmful refrigerants.

Toshiba has incorporated advanced technologies in its R410A compatible products, enhancing performance and reliability. Among these technologies is the inverter technology that allows the compressor to operate at variable speeds. This functionality leads to improved temperature regulation, reduced noise levels, and further energy savings. Inverter systems provide precise control over the cooling and heating processes, allowing for a comfortable indoor environment while minimizing wastage of energy.

R410A also exhibits excellent heat transfer properties, which boosts cooling capacity. This feature makes it suitable for large-scale HVAC systems, including commercial and industrial applications. Its high-pressure characteristics enable the design of more compact and efficient components, allowing for smaller units and easier installation.

Furthermore, Toshiba's dedication to technological innovation is visible in its commitment to research and development. The company continuously strives to optimize systems that utilize R410A, focusing on reliability and longevity. This includes improved compressor designs, enhanced heat exchangers, and the integration of smart controls that adapt to the varying load conditions in real-time.

In terms of safety, R410A is classified as non-toxic and non-flammable under normal conditions, making it a safe choice for use in residential and commercial settings. However, it is important to note that R410A operates at higher pressures compared to traditional refrigerants, necessitating proper equipment design and handling procedures.

In conclusion, Toshiba R410A stands out in the market for its energy efficiency, environmental safety, and technological advancements. It is an ideal refrigerant for modern HVAC applications, contributing to both comfort and sustainability. As the industry continues to evolve, R410A remains a pivotal element in the quest for responsible and efficient refrigeration solutions.
