Review of Digital air conditioners: error codes, comparison of duct, cassette and floor-ceiling models

Trading and manufacturing company Digital is a well-known American manufacturer. She began her work in the early 80s of the last century. The entry to the world market took place in early 2000. This brand is known to the Russian consumer for its qualities and modern design. In addition to household appliances and car electrics, the company is engaged in the production of climatic equipment.

Main lines of air conditioners and products

Initially, the production of traditional split systems was launched. Digital air conditioners differed from their counterparts in better performance properties and advanced design. Then successful attempts were made to develop the market for industrial and commercial HVAC equipment. There are more than 70 models in the assortment.

Digital product line overview:

• Household... The split system can be simple or inverter. A Toshiba compressor is used to complete the outdoor unit. Features - the presence of a deep air purification filter, a simplified technology, according to which the air conditioner is installed. The maximum power of the Dac series is up to 9 kW.
• Duct... Designed for installation in the ceiling of the room, they are characterized by high performance. Advantages - relatively small thickness, which allows installation without reducing the usable volume of the room. Application area - industrial and commercial facilities.
• Cassette... Due to their design, they can evenly distribute cooled or heated air throughout the entire volume of the room. Features - indoor installation, all models are remote control, with the possibility of remote control.
• Floor and ceiling... These Digital air conditioners are thinner than standard. They can distribute the air flow horizontally and vertically, depending on how the indoor unit is set up. Power ranges from 7 to 16 kW.
• Multi-split systems... Installation of one outdoor unit and several indoor units in different rooms is in progress. It is possible to change operating modes for each room. Ideal for large houses. At the same time, operation is no different from household counterparts. You can select an outdoor unit separately and select several indoor units according to its capacity.

It is also possible to choose the design of the indoor unit - from standard white to branded with a gold horizontal insert.

You can buy models with different air purification systems - antibacterial, deodorant, or with Gold Catalyst. Each of them has its own degree of processing of air masses, nuances of service.

Comparison of characteristics of popular models

To select the most suitable model, you need to study all the characteristics of the climatic equipment. Industrial and commercial samples are selected according to the design parameters, for household it is enough to know the volume of the room. You should first familiarize yourself with the instructions, consult with representatives of the trading organization.

Basic selection parameters:

• operating modes: cooling, heating, ventilation, dehumidification;
• system type: wall, floor-ceiling, cassette, duct;
• rated power of work;
• setting the timer, Turbo intensive mode, filter self-cleaning.

A detailed description of these parameters is available in the user manual.As an example, you can review the most popular models and compare their characteristics and prices. These data are shown in the table.

Almost all models have a sleep mode, which is important for living quarters. Another plus is the use of the safe R-410A refrigerant.

The external unit has a special anti-corrosion coating. But this does not negate the mandatory installation of the protective visor. It is best to install a lattice box so that technicians can access all parts of the unit.

Instructions for Control Panel and Digital Air Conditioners

To change the operating modes, a remote control for Digital air conditioners was developed. One of three models can be included in the configuration - C4, M4 or BW. The difference is in the number of buttons, the size of the LCD display. The first two are characterized by convenient indication of all modes. The third panel belongs to the budget category.

With the help of these devices, you can adjust the following parameters of the equipment:

• cooling or heating temperature;
• fan speed;
• switching of operating modes;
• activation of the Turbo or Sleep options;
• set the automatic shutdown time.

For correct installation and maintenance, an instruction manual is included with each model. It describes the basic rules for carrying out preventive work:

• rules for washing the indoor unit;
• cleaning the air filter;
• the frequency of checking the level of refrigerant in the system;
• installation recommendations.

The latter should be done by certified specialists. Otherwise, the manufacturer's warranty may be denied.

If the remote control is inoperative, changing the operating parameters can be done manually on the indoor unit.

Digital air conditioner error codes

During the operation of the equipment, malfunctions or breakdowns may occur. The first sign of a malfunction is the error codes of Digital air conditioners. For minor glitches, the company used standard alerts. They are displayed on the LCD display in the form of numeric and alphabetic characters. Each error code indicates a specific type of failure.

If the malfunction is significant, complex diagnostics are needed. For this, specialists use special code equipment, with which you can accurately determine the cause.
