Bosch air conditioners overview: error codes, comparison of industrial VRF and domestic models

Bosch is a leading manufacturer of household and industrial equipment, professional tools. In addition to the standard product line, she is engaged in the manufacture and sale of HVAC equipment. Bosch VRF air conditioning systems for commercial and industrial use are particularly popular.

The main line of air conditioners and products

Climate technology is developed and produced by a separate division of Bosch - Thermotechnology. The features of the product line are the use of inverter technology, the choice of types of management, professional maintenance and service. The latter is relevant if repairs are needed or if it is necessary to charge the unit with new refrigerant.

Additional advantages - the choice of maximum air conditioning power, the optimal set of functions and automation. For industrial equipment, the last determining factor. The buyer must comply with the rules of maintenance and operation, the rest will be done by the company's specialists - pick up a separate module for complex diagnostics. Many models need to be refueled at the installation site, for which you can call technicians.

VRF air conditioning

Designed to create multi-zone climate systems. Scope - industrial buildings, commercial and office centers. A combination is possible - for continuous operation use one compartment, with a maximum load of the second.

Features:

  • cooling power varies from 25.2 to 50 kW;
  • the outdoor module is equipped with five-level oil level control;
  • cooling range from -5 ° С to + 48 ° С;
  • night operating mode with noise level up to 45 dB.

A Japanese-made compressor is used for picking. Refueling is carried out through a special module, which ensures maximum service speed. In the event of a breakdown, the service will dismantle it and pick it up.

Cassette Blocks

Designed for installation in office and retail premises. Mounted in the ceiling part, the working grid does not protrude beyond the main plane. Compact models have been developed for small rooms, the dimensions of which do not exceed the size of a standard ceiling tile.

Operational and technical qualities:

  • cooling power - from 1.5 to 14 kW;
  • panels are made in the form of bee honeycombs;
  • maximum height difference with an outdoor station - 750 mm;
  • low noise.

Until recently, Aeria class models were produced, but they were replaced by new lines - C4W and MC4W.

Wall models of air conditioners

This is a classic split system with the ability to mount on the interior walls of rooms. Appearance is standard, there is no inverter. The built-in LCD screen has the maximum information content - it displays the current operating modes, air temperature in the room. Judging by the photo, the models are suitable for installation in commercial buildings or for residential premises.

Basic features:

  • performance - from 1.5 to 9 kW;
  • there is a function for tracking the remote control device;
  • several connection options;
  • low noise outdoor and indoor units.

The split system is mounted only by professionals. The maximum permissible length of the trunk, elevation difference is taken into account.

Channel systems

Designed to create an air conditioning network in industrial and commercial buildings, mounted in a ceiling space or in special engineering niches.Installation of the air conditioner is carried out only after the coordination of the particular building.

Parameters:

  • performance indicators range from 1.5 to 60 kW;
  • you can purchase a channel module with different levels of air pressure - low, medium or high pressure;
  • There is a special adapter with a filter and a tank for collecting condensate.

The latter must be taken for periodic cleaning and prevention. This should be done only by specialists.

Floor and ceiling air conditioners

A scope - creation of optimum temperature in technical rooms with constant stay of personnel. Advantages - even distribution of air flow in two directions, modern design. In some cases, they can replace the floor module.

Features:

  • cooling power - from 3.6 to 14 kW;
  • powerful fan installed;
  • automatic adjustment of the position of the blinds;
  • relatively small dimensions.

Until recently, the company produced mobile air conditioning, but due to low demand, production was discontinued. However, they had a number of advantages - simple installation of an air conditioner, mobility. Perhaps in the future, the company will resume production of the series, making adjustments to the design.

Comparison of the characteristics of popular models

For analysis, it is recommended to take the most popular product line - wall modules. They have a wide range of performance, characterized by modern design. When choosing, the complexity of installation is taken into account, how difficult it will be to repair the air conditioner in case of breakdown.

Key selection options:

  • rated power in cooling and heating mode;
  • noise level;
  • Energy consumption;
  • maximum air flow rate;
  • the presence of additional functions - sleep mode, night, timer.

Another important factor is the price. As an example, the table shows the characteristics of three popular models of the company.

Model Hw15-1 Hw36-1 HW56-1
Cooling power 1,5 3,6 5,6
Energy consumption 0,65 2,1 3,7
Air consumption 427 590 925
Noise level 33 35 40
Indoor Unit Dimensions 915*230*290 915*230*290 1072*230*315
Weight 12,4 13 15,1
Cost 14573 18500 23750

All models use R-410A refrigerant. Therefore, filling Bosch air conditioners is possible at home, but using special equipment. Mandatory procedure is pressure testing of highways.

Instructions for the control panel and air conditioners Bosch

To manage the functions of HVAC equipment, the company has developed several modules. The standard remote control for the air conditioner can be used to change operating modes, intensity. Its display shows the air temperature, the activity of certain functions. Also, the device is equipped with a temperature sensor and backlight.

Additionally, the integration of such modules and technical solutions is possible:

  • BVIM is a system module for monitoring the operation of 256 indoor units. Ability to install a workstation on a PC;
  • Modbus - designed to convert various control protocols. It can be installed both indoors and outdoors.
  • BACnet is another converter model designed for connection to a 220 V household power supply. The recommended field of application is the maintenance of climate modules in hotels and office buildings.

To learn the rules of service need instructions for air conditioners. Wall-mounted models require periodic cleaning of the air filter, filling with refrigerant. For industrial units, a more detailed instruction has been developed, which includes recommendations for installation and maintenance. The buyer should know what he must do to maintain normal condition.

A separate item of expenditure is the seasonal preparation of equipment. The list of required works is diagnostics, troubleshooting, replacement or repair of individual units.

Error codes for air conditioners Bosch

When malfunctions occur in the operation of HVAC equipment, certain conditioner error codes appear on the screen. They indicate the nature of the breakdown and are intended for the prompt detection of a malfunction and its elimination. These error codes are primarily needed for the repairman. The company uses the standard designation for breakdowns.

The user can indirectly determine the nature of the malfunction:

  • It does not turn on. A safety relay has tripped or there is no power.
  • There was an unpleasant odor. Need to clean the air filter.
  • Condensate and steam. The big difference is the temperature of the air in the room and the flow from the blinds.
  • The noise in the highways. Insufficient refrigerant volume.

Maintenance-free period depends not only on compliance with the operating rules, but also on the correct installation. This work should be done only by specialized organizations. Otherwise, the warranty may be voided.

User reviews

Despite the popularity of this brand, there are few actual user opinions on the Web. Each review indicates the build quality, adaptation to weather conditions. Industrial models have been in operation for years without revealing serious damage.

Benefits:

  • quick cooling;
  • set of additional functions;
  • a network of specialized service centers;
  • reliability of work.

Identified deficiencies:

  • the outer hose is not resistant to temperature differences;
  • a small selection of appearance;
