Review of GREE air conditioners: error codes, comparison of inverter cassette, channel and mobile systems

Trademark of Gree Electric Appliances, Inc. The company was founded in 1989 in Zhuhai (China). It began its activity with the manufacture of small window and vents air ventilation systems. The modern name and brand appeared in 1991. The company is one of the world's leading developers and the largest manufacturer of climate control equipment in the world and sets many standards in this area. The Gree brand (sometimes pronounced gri) is known both for its own end products and as the largest OEM supplier (parts and assemblies for other companies).

Manufacturing and main structures (research center, laboratories, headquarters) are located in China. In addition to five Chinese factories, the production of equipment has been set up in four more countries: Brazil, Vietnam, Pakistan, and the USA. The production is universal: ready-made systems, spare parts, custom-made components, etc. The open business model is the production of custom-made equipment for other corporations that sell similar equipment. In particular, the production of equipment for the well-known company DAIKIN.

Main manufactured air conditioning systems

All types of climatic systems existing today are produced: domestic, semi-industrial and industrial (including very precise, precision equipment). There are several types of household air conditioners: window air conditioners, mobile air conditioners, wall split systems and some multi split systems. One of the attractive features is the long warranty period from 3 to 5 years.

Wall split systems

Several episodes: Bee (Techno, Plasma, Silver, White, Gold), Bora, Cozy (Inverter), Artful, Viola, Lomo, U (POEM, CROWN, Cool), Beauty, Change (Artic, DC Inverter), Smart and etc. Perhaps this is the widest range of air conditioners within the wall split systems of all on the market.

You can choose for every taste, color and technical characteristics. There is a winter set of models designed to operate at very low outdoor temperatures down to -30 ° C. Ultra-thin internal blocks (U series) are offered - thickness 159 mm. At the same time, the noise level is 21 dB. Designed for areas from 20 to 100 sq.m. The efficiency of cooling large areas with a single unit decreases. Self-cleaning systems, a set of different filters.

The main control is carried out from the remote control. The "I feel" function (orientation to the location of the console) is basic. To protect against children, there is a blocking mode (buttons on the blocks, too, until they are unlocked from the remote control).

All air conditioners support four main modes of operation: cooling, heating, dehumidification, ventilation.

Multi split systems

A generic name for composite kits. It is an outdoor unit with a single compressor and several indoor units connected to it (up to 4). Various types of equipment can act as indoor units: wall, cassette, column, floor or ceiling.

Has a limitation not only on the number of connected units, but also on power (each unit and total). Indoor units control - independent or separately dependent (only part of the parameters are independent). The total area served by one system is up to 100 sq.m.

Cassette, window and mobile air conditioners

Cassette air conditioners are a semi-industrial type of ceiling indoor unit. Connect to universal outdoor. Differs in small thickness (23 cm). It is sometimes used as a household air conditioner.

Monoblock window systems are easy to install and maintain. Cooling area - from 20 to 38 sq.m. Manual control, work only in cooling and ventilation modes.

Mobile air conditioners are convenient if you need to periodically service different rooms. The main operating mode is cooling. The area of ​​the refrigerated room is up to 30 sq.m.

In addition to the types presented, series of industrial systems are also produced. Column, floor and ceiling, channel air conditioners, multizone systems (vrf, vrv). Among the floor-ceiling can be identified angular. The original design and placement of the corner air conditioner captivates, but its efficiency is lower due to its distant location. Recommended service areas up to 40 sq.m.

Comparative characteristics of several models

Installation of any model Gree air conditioner is not difficult, but requires professional skills. In some cases, installers must be certified to maintain warranty.

Instructions for the control panel and air conditioners GREE

The remote control for the Gree air conditioner allows you to adjust various functions, the temperature comfort of the apartment. Due to the wide variety of equipment manufactured by the company, it is difficult to single out any specific features. It can be noted that the company, following the declared principle of "The Philosophy of the Perfect Gree Air Conditioner", tries to find a balance between functionality and simplicity in each development. So in simple systems, there is no complex setting, as well as there is no possibility of smoother manipulation of comfort, economy and other things (for example, taking into account the street temperature).

The manual for Gree air conditioners contains a description of the operating modes of a specific product and is developed individually for it. Those. not a universal instruction for all air conditioners at once.

Error codes for air conditioners GREE

Gree air conditioner error codes are usually listed in the user manual. With the exception of a few of the simplest floor-standing models, all equipment has a built-in self-diagnosis system. Errors are displayed on the remote control and duplicated on the indoor unit. Decoding the codes makes troubleshooting much easier. The description is standardized for classes of the same type and is the same for classic start-stop systems and for systems with an inverter. For cassette codes, the decoding of the codes is different.

In household air conditioners, the error can be duplicated by flashing indicators (general, cold, heat) every 3 seconds. The number is determined by the number of flashes.

For a more accurate diagnosis, it is recommended that a restart occurs when a malfunction occurs. It is best to completely turn off the network for a while, while paying attention that separate units may have different connections and it is necessary to de-energize the entire set. It is enough to remove food for a few minutes. If a malfunction is still displayed after that, it is recommended to contact a specialized center and not dismantle the equipment yourself. The equipment is complicated, after self-"disassembly" may require expensive professional repair of the Gree air conditioner. Moreover, the installation of outdoor units may end badly (they are heavy enough and are installed at a high height).

User reviews

Since the model range of climate systems for the gris is very extensive, you can find a wide variety of reviews. Let's try to summarize the main points, leaving out the features of different models, include only the characteristic features inherent in the brand.

Most often, users mark the price as the disadvantages. Proprietary equipment released under the brand is at a higher cost than similar equipment from third-party firms, although it is produced at the same factories.

The rest of the shortcomings noted by buyers are most likely inherent in specific specimens and are not typical for the entire product line of the company:

  • inconsistency between power and serviced area (technical data in the operating instructions);
  • in the classic form it looks rustic;
  • uninformative display and buttons;
  • air flow can only be adjusted manually;
  • frequent maintenance - filter cleaning.

Benefits include value for money. There are inexpensive monoblock systems in a simple case and elite multisplit inverter air conditioners with ceiling placement of indoor units or on the wall.

Should I take a branded item? At a slightly higher price, there are more quality assurances here.
