Wall dualkets gas boilers Weller apply for heating systems in rooms up to 230 kV. meters. The modulation burner allows you to achieve the highest heat transfer during operation in any power, which is the main advantage of the design of this brand. The unit has a filling chamber of a closed species, as well as an additional condensation module that absorbs heat from the output gases.
Control is simple and understandable, almost all adjustments are performed automatically. Wall-mounted model Mars are connected to the standard vertical chimney, and the output of combustion products and the outside of the street occasionally occurs in a coaxial chimney.
For the maximum increase in the performance of these models, they are equipped with details and components from well-known European companies. If the automation fixes any malfunction, the display shows the error code symbol. All models are equipped with separate heat exchangers.
The control unit in the automation mode makes control of the required pressure in the pipeline and sets the most favorable mode of operation at which the use of gas will be the smallest. Before use, you need to explore the instructions. Error codes that are displayed on the display will be able to help timely detect and troubleshoot.
In the circulation system, there is not enough water pressure or it is missing. The malfunction of the hydraulic unit may be hired. Fault Microswitch Flow Sensor. When the electricity is disconnected, it is recommended to resume water supply. Increase pressure up to 1.2 bar and run heating.
This mode is installed in the instrument at a water temperature of +96 degrees, or due to problems with the ignition system. It is recommended to check the flow of gas. By pressing the "Reset" button, activate the device.
To eliminate, using the "Reset" key, we make a restart of the aggregate. In the event that the action turns out to be unsuccessful, you should contact the service center.
Due to the incorrect execution of the function by the sensor, the unit enters the protective mode. It is recommended to turn off the device from the network and replace this component. You can also call the service.
The protection cycle is activated in two cases: when the temperature of the heating system is sharply rises to 97 degrees or when the temperature of the hot water passes the boundary 81 degrees. It is required to disconnect from the power supply system. When the indicator is reduced by six degrees less recommended, run the "Reset" key.
Fault of a hot water sensor. Due to improper functioning sensor GVS. The unit enters the protective mode. It is required to de-energize it and replace the hot water sensor or contact the service center.
In some cases, when using an aggregate, it can reduce the temperature of ten or fifteen degrees in the heating system, and sometimes even disconnect. In this case, the connection of the apparatus to the power grid should be made by means of the stabilizer, so it is required to check it out. Since the stabilizer directly, may fail, and the malfunction can manifest itself only when the problem connected to the energy consumers will be detected.

Weller boiler repair assistance
For country house I want to make installation wall gas boiler Weller Mars. Please tell me what kind of nominal gas supply pressure / methan / propane / data models?
In this type of equipment, the value of the nominal pressure of gas intake for methane / propane is 20/37 mbar.
We use the boiler indoors of this brand. Before that evening, he acted well. Currently, after 5 seconds after the start, the device began to go out. It seems that it cannot deliver water into the system. Explain what kind of problem?
A probable cause of such a defect can be an ignition electrode that does not see the fire, or a decrease in circulation.
I installed a two-circuit boiler Mars 32 OC. When starting the burner flames and immediately goes out. I believe there is no fastener spark. Help delete this accident?
It is required to check whether the sound is heard during the formation of the foster spark, if the wire is retrieved to the ignition. If there is no sound, you must change the ignition transformer. If there is sound, make the replacement of the wallet electrode or burner.
Performed at the end of 2016 connection of this unit. Presumably after five months a failure arose. I tune the temperature, and he does not hold it. Explain what could be?
Perhaps the automation failure occurs, and at the time of the rise temperature of 65 degrees, the nozzles are disconnected. It is necessary to adjust the automation for the correct execution of functions. Another factor can be that the inconsistent power of the unit in relation to the heated area is selected.
MARS 32 gas boiler in DHW mode works with interruptions (practically does not work). There is an unusual behavior from him. When the crane is turned on, the water heat is heating almost to boiling water, despite the fact that the sensor costs +40 degrees. After 2-3 minutes, the boiling water turns off, cold water flows. After 2-3 minutes turn on and again brings the water temperature to boiling water. And so 4 times after the last heating to boiling water issues cold water And no longer turn on. The heating circuit is working normally (no longer checked-summer). After turning off the boiler, and it will flash about 2 days a de-energized and closed water supply crane, it turns on, and again the same trouble. What needs to be done, can change something?
You need to replace the temperature sensor.
Faced repair with Weller boiler. After a few seconds after its inclusion, it gives an E1 error. Nutrition is not fed to the pump. The pump works, called the winding, capacitor. Food from the board does not go. Someone came across in his practice with this problem?
It is necessary to start with the fact that this model has twice a survey of the coolant duct sensor. Before starting the pump, it should be open, after - is closed. If any of the conditions is not fulfilled - E1 error.
Boiler Weller Mars 26. Gives an E02 error, ignition error. The flame lights up and sweeps. When the combustion chamber lid is removed normally. As soon as you close the lid, it goes out. Chimney clean, changed fan, pneummatore, gas valve, ignition electrode, ignition unit. Nothing helped. Electrical network normally. Who can help?
Turbated models on the contrary should be. I would venture to assume that either oversupply, or a large lack of air.
Boiler Weller Mars. 26. In the work very clocks. For example, it costs 40 degrees to heating, it turns on, quickly warms up to 38-40 degrees, the burner goes out, the temperature quickly falls to about 32-33, and the burner starts again and so in a circle. If you increase the temperature, for example, up to 48, the unit warms for a long time (the same temperature in the area of \u200b\u200b49-50 or decreases even for a degree). When all the water is heated in the batteries, the burner goes out, and then slowly temperature drops. The burner turns onAnd now he again begins to tact again. What thoughts? Bad permeability in the heating system? Is there a filter in it? Gas is not adjusted? And can I increase the delta?
It looks like a model malfunction of the electronic board, when the unit ceases to modulate the flame and heats at the maximum.
Mars 26 boiler. The boiler does not start. I do not write anything (two zero shows), does not respond to the reset, the turning button turns the board. The unit is double-circuit, the contour on the water is closed with two plugs. Gas is normal. Pressure in the system of 1.5-2 atm. The boiler turned off, since there were problems with gas supply, the pressure fell to 0, but the errors did not give out. Last time there was a similar situation: the light was turned off for half a day, the pressure fell, it did not turn on, issued a mistake (little pressure). I raised the pressure, but it did not turn on anyway. Two times protraffers and stands. Somehow it happened (I downloaded more than 2 atm. Pressure and then decided to make a little up to 1.5), which is the next turn on the electric rod, the unit immediately began to twist the pump and then turned on. And this time everything is in no way. What could it be?
There was a similar problem. The boiler issued an E6 error, apparently he lacks thrust or exhaust bad, pulled the tube from the sensor to the fan. One tube somehow stuck on the fan and snapped Piezo. I made a reset, the device quickly tested, launched the fan and lit a burner. The second tube did not stick, waited for two hours, while the system and chimney of the inner air will warm up. Turned off, then I installed all the tubes, as it was, turned it on, and it started normally.
Help please in the problem: Mars 32 OC boiler does not turn on, shows E1 error (no pressure in the heating system). The pressure is normal, above 1 bar, the pump does not start, a weak click is heard. A red LED is on on a DVT sensor. DHW, although I do not use the DHW, the output is muffled there, and through the input only I carry out the unit.
For a start, see the GVS duct sensor, clean or replace the bronze screwing "cartridge". Then watch the heating duct sensor. Most likely, it will be covered with water. You need to change the gland and dry the microswitch.
A year ago they were connected to the system this device. Today, the wick lights up at the time of startup for 10 seconds, and the main burner does not pick up the fire, and the unit goes out. How can I get out of the situation?
Probably, the ignition automatic is not operational or a burner problem. Just in case, look, whether the phasing has not confused during the connection to the power supply.

Operation and repair of boilers
Li Chinese really heating boilers - Is it a poor-quality default technique? Most buyers in the Russian Federation have developed a sustainable opinion that it is not without reason. But this stereotype can be destroyed by considering specificationsthat have heating gas boilers Weller.
The main difference between the products of the brand Weller is undoubted quality, reliability and convenience in operation. One of the best evidence of the popularity of the model is that the thermal generators of the company are popular not only in the territory of the Russian Federation, but also in more demanding, European buyers.
Surprisingly, the manufacturer managed to do that for other concerns it turned out to be unable to maintain European quality and specifications, making the cost of production below and, accordingly, attractive to the consumer.
Produced models are focused on the consumer heating of the house. The consumer offers mounted models, two-circuit type with closed chamber combustion.
What explains the popularity of the boilers presented by Weller? 
Judging by the reviews of buyers, the only weak place The Weller heat station is the vulnerability of the control unit to the voltage drops on the network. Security can be safely installed by the UPS.
Adjusting and configuring the boiler after installation is not required. The control unit in automatic mode monitors the pressure in the pipeline and selects the optimal option to work, such that the consumption of natural gas is minimal.
The work of the boiler Weller depends on some factors that will need to consider before starting the installation:
Ease of operation is achieved due to the system of "intellectual" control of the work of the boiler. The installed controller independently makes decisions about changing the mode of operation depending on the external and internal factors, making the device in the most comfortable and cost-effective.
Boilers were designed for quarter heating, can be installed in small rooms, without having to use a separate boiler room for these purposes. A good choice For residents of an apartment building!

Two-kinning mounted gas boilers Weller are designed for the heating of rooms up to 240 square meters. Maximum heat transfer, when working at any power, allows the use of a modulation burner - the main advantage of the design of these boilers. Equipment in devices closed typeIn addition, there is an additional condensation module, which also collects heat from the assigned gases.
Man's participation is not required when controlling, since all settings are performed automatically. Wall boilers Weller Mars is connected to the classic vertical chimney, and the removal of combustion products and the fence of fresh air occurs with a compulsory way through a coaxial chimney.
In order to increase the performance of this brand, all of its models come with nodes from leading European companies - WILO, SWEP, Fugas, etc. In case of detection of automatic fault device, an appropriate signal is given to the display where error codes are displayed.
All units are equipped with separate heat exchangers, and the control unit automatically controls the required pressure in the pipeline and sets the optimal version of the operation at which the gas consumption will be minimal. When operating, you need to study any gas boiler Weller. Errors appearing on the screen will help to identify the problem and quickly solve it.
ERROR E1 - insufficient water pressure or no water in circulating system. Faulty hydroblock - can eat rod. Faulty microswitch stream sensor. With the electricity disconnected, in accordance with the instructions, feed the water again. Raise pressure up to 1-1.2 bar and turn on heating.
ERROR E2 - worked protection against overheating or faulty ignition. The boiler enters such a mode at a water temperature of +95 degrees, or due to faulty ignition. Check gas supply. Press "Reset" and start the device again.
E5 code is a software malfunction. Press the "Reset" button or restart the device. If it does not help - call a specialist.
ERROR E6 - Sensor heating system faulty. The boiler entered the protective mode due to improper operation of the sensor. Disable the device and replace the corresponding item. If necessary, invite a specialist.
The E7 code is an increase in the temperature of the coolant. The protective mode is activated, with a rapid increase in the temperature of the system to 95 degrees, as well as with increasing DHS up to 80 degrees. Disconnect from the power, and when the indicator decreases by 6 degrees less than the specified, start it with the "Reset" button.
E9 error - triggering on a malfunction from the DHW sensor. Due to the abnormal operation of the sensor, the boiler entered the protection mode. Disable power and replace the sensor. Or call a specialist.
Duch sensor GVS.
Sometimes, when operating boilers, Weller, the device suddenly begins to drop the temperature in the heating system. 10, or even on 20 degrees. It may even completely turn off. At the same time, it is connected to electrical network through the stabilizer.
In such a situation, check the stabilizer. Quite often, such devices arise unnoticed for the eyes, and the problem is detected only when the breakage of the consumers connected to them are detected. It is recommended to use a voltage stabilizer when connecting gas boilers.
