Review of Daikin air conditioners: error codes, comparison of duct and cassette inverter models

The Daikin concern is a giant in the field of HVAC equipment, which rightfully occupies one of the leading positions in this market segment, since the company's assembly fully complies with all European regulatory requirements and standards, as evidenced by the ISO quality certificate.

Corporation Daikin Europe N.V., which is a subsidiary of Daikin Industries Limited located in Japan and includes 5 production sites, 5 sales departments and 17 subsidiaries for the production of high-tech climate equipment. This allows us to perform a high-quality selection for each specific task.

Thanks to all of the above, the Daikin split system can be installed both in a small apartment and in a large industrial building without violating health and safety requirements.

Main lines of air conditioners

As Daikin Corporation has developed around the world, its service centers can be found in Asia, Europe, Australia, Russia, USA and China. Thanks to this, the leading engineers of the company have developed a huge range of 6 categories, which includes:

• Wall mounted air conditioners (FTXB25C / RXB25C, FTXG50L / RXG50L, FTXZ25N / RXZ25N).
• Ceiling (sub-ceiling) or floor split systems (FVXG35K / RXG35L, FLQN60EXV / RYN60CXV, FVXG50K / RXG50L).
• Duct air conditioners (FBQ60D / RXS60L, FBQ35D / RXS35L3, FBQ100D / RQ100BV).
• Multizone VRV systems (BTSQ20P, RTSQ16PA, REYQ18T).
• Cassette air conditioners (FCQG125F / RR125BW, FFQ25C / RXS25L, FCQG125F / RQ125BW).
• Column devices (FVQ140C / RZQSG140L7Y1B, FVQ125C / RZQG125L7V1B, FVQ100C / RZQSG100L7V1B).

Since the range of Daikin air conditioners is simply huge, it is often difficult for an ordinary consumer to choose. It is for this reason that this informational article was developed, which will allow you to parse information about the main advantages of Daikin products, as well as about the advisability of installing a particular system in a certain room.

Wall-mounted multi split systems

The wall-mounted household air conditioner of this brand is mainly installed in apartments, wine cellars, offices or small shops up to 70 m² (FTXS71G / RXS71F). It consists of 2 blocks:

• Indoor with adapter for indoor installation.
• Outdoor for outdoor mounting to a wall or facade.

The distance between the aforementioned blocks can be up to 30m, which makes it possible to place the indoor block anywhere in an apartment, office or private house.

Daikin air conditioners work thanks to the safe R 410A freon, which allows the system to function effectively when the room is heated at an outdoor temperature of up to -15⁰FROM.

The most popular brands of wall-mounted air conditioners for Daikin rooms are EMURA and designer URURU SARARA, the last of which were presented to the public on October 1, 2016, and they became available to the public on November 1, 2016.

Competitive advantages of wall-mounted air conditioning split systems

• High energy consumption class A +++ when operating in ECONO mode.
• If there are no people in the room for 20 minutes, thanks to the built-in electric motion sensor (FTXG-LW), the system goes into standby mode and energy consumption is reduced by 80%.
• The presence of the "Online controller" function that allows you to turn on for heating, start a humidifier or check the system using the Internet or a special application running an Android program.
• Thanks to the presence sensor, the intelligent air conditioning system redirects the air mass in the opposite direction from the location of the people.
• Mixing fresh air into chilled air (FTXR28E / RXR28E).
• The basic kit of Daikin EMURA air conditioners includes a titanium apatite deodorizing filter that completely removes dust, chemicals, viruses and bacteria from the air.

For example, consider the main characteristics and differences between the most popular models of Daikin air conditioners.

Comparison of characteristics of popular models

The above systems are easy to install, do not require special care and fully fulfill the functions assigned to them.

Next, consider the range of air conditioning systems that have no analogues.

Multi-zone VRF and VRV systems (VRV)

These versatile systems from Daikin are designed for server rooms, large shopping malls, large industrial plants and similar locations where multiple devices need to be connected to a single outdoor unit.

This industrial range of air conditioners has the following advantages:

Description of the distinctive features of multizone VRF systems

• The manufacturer's warranty service is 60 months.
• Efficient heating or cooling of rooms up to 550 m2² with an air conditioner marked REYQ18T, which produces 50.4 kW when cooling and 56.5 kW when heating.
• Presence of a precision capacitor and automatic testing function.
• The length of the inter-block line can reach 1 km, which does not freeze even in very severe frosts.
• These systems can be either rooftop or cabinet-type.
• The presence of a heat pump and heat recovery function, which allows the equipment to operate at ambient temperatures down to -25⁰FROM.
• Possibility of inserting the system into a centralized ventilation and air conditioning channel.

Duct air conditioners

Daikin duct air conditioners are a type of climatic equipment for semi-industrial and industrial buildings. They are mounted in suspended ceiling structures and are integrated with a centralized ventilation and air conditioning system.

The main advantage of this type of climatic equipment is the control over the microclimate in several separate rooms.

The most widespread are the following models of Daikin channel air conditioners: FDXS-E / C / RXS-J, FDMQN-CX / RYN-CX / RQ-C (D) X, FDQ-B / RZQ-C.

Semi-industrial cassette air conditioners

Daikin's company, unlike its competitors, was one step ahead, since not only the best engineers were involved in the production of this type of equipment, but also the Yellow Design design studio.

Thanks to this solution, it was possible to easily select an elegant and ergonomic air conditioner that is flush mounted in the ceiling, fully compatible with its design, while providing high quality air conditioning.

In addition to all this, Daiken cassette air conditioners have the following features:

Main technical features of Daikin cassette air conditioners

• High energy efficiency of A ++ devices and efficiency.
• Saving of R 410A refrigerant is 12% when compared with competitive models due to a special pump.
• The devices are equipped with an inverter drive with 5 speeds, which controls the air flow, spare parts for which can be purchased at any specialized store.
• The air inlet is located in the center of the indoor unit, which, if necessary, can be removed to clean the filters.

Based on the above material, it can be noted that Daiken is very scrupulous about the products it produces, in order to take first places in various competitions for air conditioning equipment and receive positive feedback from its satisfied customers.

Since all systems of this class are controlled remotely, the remote control for the Daikin air conditioner, its main purpose, decoding of buttons and basic capabilities will be considered below.

Daikin control panel and air conditioners manuals

In most cases, the manual for Daikin air conditioners already contains information on how to work with the remote control. However, there are often cases when this technical documentation (manual) is lost for some reason.

In such cases, you can contact the manufacturer with a request to make a duplicate of the instructions for the remote control, but it will be more rational to get acquainted with the following photo, where you can find all the main functions of the air conditioner, the purpose of the buttons on the remote control and the principle of the system.

Daikin air conditioner error codes

In 99% of cases, Daikin products demonstrate high technical and economic performance. However, the following malfunctions sometimes occur:

• Failure of the control board or coordinator;
• a burned-out electric motor rotating the supply fan;
• breaks through a high-pressure pipeline, etc.

These malfunctions are instantly detected by the self-diagnosis system, after which the indicator on the indoor unit informs about the emerging emergency situation (a paw with an error code is blinking). In this case, it will be useful to familiarize yourself with our selection, which indicates the manual (passport) with the main errors, their decoding and how to fix them.
