User manual
The operation of Beretta boilers is carried out in automatic mode that does not require constant participation of a person.
The user is required only to adjust the heating mode by his own sensations, the transfer of the boiler into a winter or summer mode (disconnecting or starting the heating circuit), maintaining the cleanliness of the case and periodic maintenance (service employees).
All serious problems are solved only by the challenge of the master. The elimination of constantly arising errors or incomprehensible phenomena occurring with the boiler in working mode.

In addition, the user independently fills out the system with water (or feeding if necessary).
The process consists in feeding the liquid through the fuel tap and filling the system until the water pressure reaches 1-1.5 bar. This is below the working pressure, but when heated, the water will expand and due to an increase in volume, the pressure reaches the desired value.
The boiler starts automatically when installing the required temperature of the coolant in the system.
It is forbidden to pour water into a hot boiler due to the danger of the destruction of the heat exchanger. You need to wait for the cooler of the boiler, and only after that pour water.
Popular breakdowns and their elimination
The lower the serial number of the error, the more often it occurs during the operation of the Beretta boiler.
Consider the most common errors and possible ways to eliminate them:
- A01. Blocking due to lack of flame. There are several reasons. Problems with the supply of gas in the trunk line, the gas supply crane into the boiler is blocked, the nozzles of the burner are very clogged. Find out if there is gas in the line, clean the burner and nozzles.
- A02. Overheating of the heat exchanger indicates a lack of water. Check the operation of the circulation pump and the pressure of the OS, add the liquid to the system.
- A03. High pressure in the chimney indicates blockage of the output of ice, hoarfrost, accumulation of soot. Weather factors are possible. A strong gusty wind.
- A 04. The drop in the pressure of the coolant can be caused by a lack of fluid. Check the system for leaks, if detected. Eliminate.
- A05. Problems of the thermoresistor of the DHW line are eliminated by the replacement of the sensor.
- A06. The thermoresistor of the heating circuit, failed, is subject to immediate replacement.
- E33. It is necessary to change the electrodes in a plug of power. Beretta boilers are phase dependent, do not work when the phase wire is incorrectly connected.
- E46. Exceeding the permissible temperature of the coolant indicates the problems in the circulation of the liquid. Check the operating mode of the circulation pump.
- The symbol of the “bell” flashes (bell, p). This is a signal from the chimney pressure sensor indicating an obstacle to the yield of smoke, the formation of ice or hoarfrost at the output of the pipe.
The beretta boiler error reset is carried out by pressing the shutdown button and re-turning on the boiler after 5-6 seconds.
How the self.Diagnosis system works?
In Beretta boilers, a self.Diagnosis system consists of a network of control sensors located on the main working units.
After turning on the boiler, the sensors begin to function in continuous mode, they do not need an additional special launch. By the same principle, the shutdown of sensors is impossible without stopping or blocking a gas boiler.
In all the main nodes of the Beretta gas boiler there are sensors (sensors) that apply signals with an error code on the display when discovers are detected

When changing the tracking parameters or violation in the operation of a particular node, the signals from the sensors are supplied to the control module that blocks the equipment. At the same time, an error code that allows the boiler owner to determine the type of problem is displayed on the display and take measures to eliminate it.
In addition to the display, special indicators located depending on the design features of different models of thermal equipment signal the Beretta boilers.
How to check the sensors
All Beretta boiler sensors are part of the self.Diagnosis system. They not only perform control functions, but also themselves are objects of observation.
This means that, when failing, short circuit or cutting of the wires of any sensor, the corresponding error code on the control panel of the boiler will immediately appear. The sensors survey by the system are automatically at the time of inclusion, no special actions are required from the user.
Most of them are thermoresisters responding to a change in the temperature regime or the output of indicators for the framework established by the mode of operation. The design of the elements is simple, the replacement is not difficult if necessary and does not take a lot of time.
It is not recommended to change any elements of the boiler on your own, you need to call a master from the service center.
