Wall double-circuit gas boilers Weller are used for heating systems in rooms up to 230 sq. meters. The modulating burner allows you to achieve the highest heat transfer when operating at any power, which is the main advantage of the design of this brand. The unit has a combustion chamber closed view, as well as additional module condensation, which absorbs heat from exhaust gases.
Management is simple and clear, almost all adjustments are made in automatic mode. wall models Mars connect to standard vertical chimney, and the output of combustion products and air intake from the street occurs by force by means of a coaxial chimney.
To maximize the performance of these models, they are equipped with parts and components from well-known companies in Europe. If the automation detects any malfunction, the display shows a symbol with an error code. All models are equipped with separate heat exchangers.
The control unit in the automatic mode controls the required pressure in the pipeline and sets the most favorable operating mode, in which the use of gas will be the least. Please read the instructions before use. The error codes that appear on the display can help you detect and fix the problem in a timely manner.
Error code E1 - Pressure error
There is not enough water pressure in the circulation system or it is missing. Hydraulic unit failure, possibly stem sticking. Faulty flow sensor microswitch. In the event of a power outage, it is recommended to restore the water supply. Increase the pressure to 1.2 bar and start heating.
Error code E2 - Protection against overheating or incorrect ignition
This mode is set in the device at a water temperature of +96 degrees, or due to problems with the ignition system. It is recommended to check the gas supply. By pressing the "reset" button, reactivate the device.
Error code E5 - Malfunction of the control board program
To eliminate, by pressing the "reset" key, we restart the unit. If the action is unsuccessful, you should contact the service center.
Error code E6 - Damage to the heating system sensor
Due to the incorrect performance of the function by the sensor, the unit enters the protective mode. It is recommended to unplug the machine and replace this component. You can also call the service.
Error code E7 - High coolant temperature
The protection cycle is activated in two cases: when the temperature of the heating system rises sharply to 97 degrees or when the temperature of the hot water supply crosses the border of 81 degrees. It is required to disconnect from the power supply system. If the indicator drops by six degrees less than the recommended one, start by pressing the "reset" key.
Error code E9 - DHW sensor error
Malfunction of the hot water sensor. Due to the malfunction of the DHW sensor, the unit enters the protection mode. It is required to de-energize it and replace the hot water supply sensor or contact a service center.
In some cases, when using the unit, it can reduce the temperature by ten or fifteen degrees per heating system and sometimes even turn off. AT this case the device must be connected to the mains by means of a stabilizer, so it is necessary to check it. Since the stabilizer itself can fail, and a malfunction can occur only when a malfunction is detected, the energy consumers connected to it.
Are Chinese heating boilers Is this a low-quality technique by default? The majority of buyers in the Russian Federation have a strong opinion that this is not without reason. But this stereotype can be broken by considering specifications which have Weller gas heating boilers.
The main difference between Weller brand products is undeniable quality, reliability and ease of use. One of the best proofs of the popularity of the model is that the company's thermal generators are popular not only in the Russian Federation, but also among more demanding European customers.
Chinese brand Weller
Weller was originally introduced as Italian manufacturer. Over time, products began to be produced in China. Today, Weller is owned by a Chinese company.Surprisingly, the manufacturer managed to do what other concerns could not do - to save European quality and technical characteristics, making the cost of production lower and therefore more attractive to the consumer.
Produced models are focused on apartment heating of the house. The consumer is offered hinged models, double-circuit type with closed camera combustion.
Mounted boilers in demand on the market
If we turn to statistics, it becomes clear that for the average consumer, the most attractive choice is mounted models. heating equipment. The number of sales of units that can be hung on the wall significantly outstrips the sales of boilers that require installation on the floor. This is especially evident in the case of apartment owners. high-rise building wishing to make autonomous heating.What explains the popularity of the boiler models presented by Weller? 
Judging by customer reviews, the only weak point thermal station Weller is the vulnerability of the control unit to voltage drops in the network. You can ensure safety by installing a UPS.
General principles of installation and use
The manufacturer, developing this model, first of all focused on the production of a boiler that would be easy to install and maintain. As a result, installation does not require compliance with special conditions and the connection of additional equipment, it is carried out quickly enough.Adjustment and adjustment of the boiler after installation is not required. The control unit automatically monitors the pressure in the pipeline and selects the best option for operation, such that the flow natural gas was minimal.
Work Weller boiler depends on some factors that you need to consider before starting installation:
- Compliance with the recommendations and requirements of the manufacturer. For example, a supply and exhaust adapter is installed in the smoke exhaust system, which monitors the presence of draft in the chimney. Violations during installation coaxial pipe lead to the failure of automation to turn on the boiler.
- Electrical connection and installation of temperature sensors must be carried out by a qualified person.
Ease of use is achieved thanks to the system of "intelligent" control of the boiler. Installed controller independently makes decisions about changing the operating mode depending on external and internal factors, making the operation of the device as comfortable and cost-effective as possible.
Away with the prejudices that China is of poor quality
The example of Weller equipment proves that China is not always bad, and sometimes even very good. Full automation of the heating process, adaptation to domestic conditions, no need for self-adjustment pressure, smart automation - all these functions put the company's models on a par with European counterparts.The boilers have been designed for apartment heating, can be installed in small spaces, without the need to use a separate boiler room for these purposes. A good choice for tenants of an apartment building!
