Circulation pump in the design of a gas boiler

Many designs of single.circuit and double.circuit gas boilers include a circulation pump. The purpose of the circulation pump in the very design of the boiler, similarly to the purpose of the pump, if it is set separately. The pump provides circulation of the coolant in the heating system, and as a result, increases the productivity of the boiler, reducing fuel consumption (gas).

Circulation pump in a gas boiler

The circulation pump in the design of the gas boiler accelerates the coolant according to the heating system, due to which the coolant is cooled in the system slower and returns to the boiler in a “heated” form. Since heating in the boiler occurs to a certain temperature, the next heating cycle will be shorter. Hence the lower gas consumption and fast water heating cycles (above the efficiency).

It is believed that for hydraulic heating systems it is not required to install circulation pumps, however, it will not interfere at all in old heating systems with large diameter pipes.

When buying a gas boiler with a circulation pump in the structure, you no longer need to put a separate circulation pump in a heating system.

Single.stage and two.stage pumps

Typically, two.stage pumps are included in the design of the gas boiler. The steps of the pump is the speed of rotation of the pump blades. This is usually 2500 and 2800 revolutions per minute. At the factory, a second stage is installed (high speed).

Place of installation of the pump in a gas wall boiler

The circulation pump is placed next to the hydraulic block of the boiler.

Connection of the pump to electricity

The circulation pump in the design of the gas boiler is already connected to the distribution shield of the boiler and is turned on when the electricity is connected to the heating boiler. Supply voltage 230 ± volt.

Preparation of the pump for the launch of the boiler

Before starting the boiler, the system should be an weapon. For this, at first the air is removed from the pump, it has a cork, and at the top of the pump, there is a purge valve. First, the valve of the heating system is unscrewed. Air is available from the system. Then, the pump itself.

Additional functions of the gas boiler pump

The gas boiler pumps, in addition to launch and work modes, have a reached mode. The pump continues to work after turning off the boiler and removes heat from the combustion chamber when the boiler is turned off. This avoids temperature peaks and extends the heat exchanger service.

The principle of operation of the circulation pump Wilo MTSL 15/5 he. 2

The main part of the pump is an electric engine consisting of a stator with several inductance coils to adjust the speed of rotation, and the rotor, which is integrated on the shaft with bearings.

When power is supplied to one of the stator windings, an electric field is created, which drives the rotor with a turbine. The turbine blades capture the liquid from the suction pipe and move it on the output pipe. In this way, the coolant is circulated along the entire heating circuit.

Consider the main reasons leading to the breakdown of the pump Wilo MTSL 15/5 he. 2.

Unstable voltage in the network

With low power, the pump engine slows down its work until a complete stop. With increased voltage, the coils of inductance occurs, due to which an interval circuit or the burden of the winding wires may occur.

Pollution of the pump mechanisms

At a liquid temperature of more than 60 ᵒ С turbine and shaft, a scale may form, which will inhibit the rotation of the motor anchor. The reasons for the jamming of the pump can be increased oxidation of moving mechanisms or entering foreign objects.

Poor.quality material of components

If the pump uses parts made of low.quality materials. its resource is sharply reduced. For example, the shaft begins to jam due to the formation of a rust layer on the surface of the bearings, because they are made of bronze, which includes iron. Such symptoms are characteristic of a non.original model.

Incorrect operation of the device

Water through a working pump should constantly circulate at a certain speed. In case of violation of the movement of the coolant (the valve or the supply line is blocked, the system filter is clogged, etc. D.), the device will overheat the bearings and coils of inductance. this will lead to jamming of the rotor, a break or closing of the stator winding.

The circulation pump Wilo MTSL 15/5 he. 2 cannot be used when there is no water in the pipeline. But since the double.circuit automatic unit of Ariston is equipped with fluid pressure sensors, the boiler will not turn on in the absence of water in the system or its low pressure.

Ariston error description for overheating

Depending on the dynamics of the change and the difference in readings from the sensors, the boiler will give out various errors: error 103. temperature growth rate on the NTC 1 sensor (the supply pipeline. on the left at the exit from the heat exchanger) is more than 7 degrees per second. At first, an error 1p1 may appear if, after restarting the boiler, the situation is repeated. an accident with an error 103. Temperature changes control are continuously every 100 milliseconds except the first four seconds after the burner launches.

Error 104. temperature growth rate on the NTC 1 or NTC 2 sensor is more than 20 degrees per second. It differs from 103 in that control occurs additionally even after turning off the burner for 7 seconds.

Error 105. temperature difference on the NTC 1 or NTC 2 sensors is more than 55 degrees. It is checked constantly with a working burner, as well as for 7 seconds after turning off. An error 1p2 may first appear, if the situation is repeated twice within four minutes. there will be an error 105.

Error 106. supply temperature larger than temperature of the reverse pipe 10 degrees. Checked constantly, error 1p3 may appear first.

Error 107. similarly 106: feed temperatures larger than temperature of the reverse pipe 30 degrees.

The presence of actual overheating on the heat exchanger, as a rule, can not be confused with anything-this is a characteristic crack due to boiling water inside. Overheating may be accompanied by water discharge through the emergency valve. because the pressure increases.

Gas boiler Ariston Error 104 What to do?

There are two relay (RL 03 and 04) in the power chains. They are not mounted on the boiler Ariston boiler: there is only a contour of radio components and conclusions. But measurement for the convenience of identifying the cause of code 104 can be maintained here by applying probes to the corresponding points. The presence of voltage indicates the serviceability of the relay, the absence. a malfunction (breakage of the winding, burning contacts). To eliminate error 104 Ariston will have to be changed.

Advice. In the purge mode, the regularity of the launch of the pump is controlled. Inclusion through time. a sign of problems with a relay that supplies power 220V. Better to immediately put another.

The electric part of the pump

If the power is supplied to terminals, wire defects, contacts are not detected. problems with the winding winding. The probable cause of error 104 is an inter.trower circuit that reduces the speed of rotation of the axis. It is impractical to eliminate such a defect in the workshop. the pump is replaced by a serviceable sample. For boilers Ariston are sold in specialized stores.

Advice

  • You can temporarily eliminate the error 104 by accurately closing contacts 5 and 6. This simulates the relay, the pump is included in the work. And although the impeller will rotate more slowly, Ariston’s boiler will not stop in the accident, and the house will not be protruded. If there is no alternative heating option. a good solution to the problem.
  • When purchasing a other marking relay, you need to pay attention to the contact groups (type) and the supply voltage. For boilers Ariston. 24V.

Sensors

The schemes indicate NTC 1 and 2. They respond to the rapid increase in the temperature of the fluid passing through the boiler Ariston. With an increase of 20 0C per second, a signal that forms an error 104 per second.

Their testing is carried out by measuring the resistance when the unit is disconnected, when, in addition to code 104, others (103, 105) are displayed, depending on the displayed mode. In the user manual, the table data on R: if the values ​​are discharged, the sensor changes.

Heat exchanger

The last “object” identifying the cause of the error 104. If the measures taken have not given a positive result, the device is dismantled and served. Poor quality of fluid (water, “non.freezing”) leads to the accumulation of salt deposits, the smallest fractions of dirt, rusts on the walls of the cavity. Cuts down, the speed of circulation drops, the boiler Ariston overheats.

Council on your own maintenance of the heat exchanger is not qualitatively carried out. And although there are enough recommendations on thematic sites, it is better to give to the service workshop. For 2-3 days you will have to switch to a reserve heat generator, but until the end of the season, for this reason, an error 104 will not arise. On your own, quickly do not clean the device from scale: you have to wait until it softers when filling the inside with an aggressive composition. And then thoroughly, under pressure, rinse. In any case, the boiler Ariston is drew out of operation, and the time costs are almost identical.

On a note. To minimize the risks of reducing the flow velocity and stopping the boiler Ariston with an error of 104 during the heating period, you need to prepare for it. This code is caused by a number of factors, and in the off.season all the elements of the circuit are subject to maintenance, and not just the unit. Radiators especially need this, which many forget about.

Repair of the Ariston boiler control unit with an error 104. insufficient circulation

Hello, dear visitors to the Blogvp site.ru!

Once my gas double.circuit boiler Ariston Clas 24 FF, again demanded an urgent, surgical intervention. The reason for this was his next behavior.

The boiler, being in heating mode, turns on, lights up and after a few seconds making terrible sounds of rapid boiling water in the heat exchanger with some kind of mechanical click turning off and goes into an emergency mode with an error code 104.

Insufficient circulation, error 104. How I was looking for the reason

According to the manual, I determined that 104 is “insufficient circulation” I argue: what can interfere with normal circulation? After all, for example, a clogged filter in the heating system or slag that has accumulated in the primary heat exchanger can interfere with the desired duct of the coolant. Maybe there may be a reason in the circulation pump? Really flew the pump? To check it unscrewed the descent of the screw on it, this will allow you to see the shaft or not.

This must be done carefully since the water may begin to go out, not much, but it is better to put some kind of rags so as not to get on the board.

There is a slot on the shaft under a wide, flat screwdriver, I tried to turn the shaft with a screwdriver I didn’t jam, it rotates. I try to start the boiler and observe whether the shaft will rotate. The boiler reproduces its terrible sounds and again goes into defense. The shaft does not rotate. At the time of the launch, I tried to crank it with a screwdriver I thought, what if the “dead point” appeared No, the rotation of the shaft did not follow.

I decided to check the supply voltage of the pump. When the presence of 220 volts was discovered on the chip, the conclusion was unequivocal The pump is replaced. Eeeh I think again unforeseen expenses.

However, the conclusion was hasty when he was looking for wires coming from the board to the circulation pump motor, he noticed that there were more than two of them. For what? I started to understand and that’s what I found out.

Why may error 104 occur. insufficient circulation. Eliminate the malfunction

The circulation pump of the boiler has two rotation speeds in the manual, they are designated as V2 (55 W) and V3 (80 W) controls the pump speed of naturally an ECU.

In hot water supply mode (DHW), the pump operates at speed V3 for better heat transfer.

In the central heating mode (CO), the control unit switches the speed of the pump, depending on the temperature difference at the input and output of the heating system.

Therefore, the pump is controlled not by one, but two relay. One feeds 220 in., and the other controls the speed.

To check these power circuits of the pump will have to turn it on. But for this you do not need to light a boiler, but we do not want to rape it! There is a simple and quick way to turn on the pump without lighting the burner.

You need to put the boiler into the “purge” mode for this, click on the boiler panel, the ESC button and hold the pressed more than 5 seconds. The purge mode is turned on. during the operation of this mode, the circulation pump is launched and operates in cycles of 60 seconds. v. 30 sec. and so on for 6 minutes. And at the same time without ignition of the burner. And we need it!

Elimination of breakdowns in Ariston Clas boilers

Ariston Class 24 gas boiler cannot start. If you hold the inclusion key, the burning device works normally. But if you do not fix the key, the device fades. Tell me the reason for the problem? Most likely, damage to the thermoelectric converter or gas valve. There may also be a decrease in gas pressure on the input pipeline. In some cases, there is a lack of voltage of the electronic board. There was a malfunction. Inclusion is very poor. The smell device lights up, and there is no flame on the main gas.air equipment. Someone can explain what reason it is? Apparently, a functional failure of the ignition node. You will need to conduct maintenance of the unit and clean the ignition mechanism. Because of what the wall-mounted boiler Ariston Clas X 24 FF stops turning off while it gains the required temperature? Heating goes to 90 degrees, then falls into the failure. When rebooting, the problem should be again. We assume that the electronic board is not in order, the temperature sensor of the boiler water requires a replacement, has a fault button of the safety sensor button. It is possible that the automation adjustments have arisen. Could you tell me why it doesn’t work out to raise the temperature of the coolant more than 70C? We need to configure more, and on the display it is displayed that this is the greatest value. How to set up heating? If the device does not increase the temperature of the heating circuit, then the following problems are possible. In adjustments there is a limitation on the highest heating temperature up to 70 s. There was a decrease in the chimney thrust. Ariston Class X poorly performs work in the process of heating the circuit supply circuit with hot water. From the tap in the kitchen can go in turn either cold water, then hot. Please help with what is the problem? Sources of the occurrence of a violation of functions can be the following. There was a cold water in view of the fact that a three.way valve is unemployed. The heat exchanger clogged with garbage. We recommend that you clean it. There is a crane under the boiler, water constantly oozes from it. The device itself will not start. What needs to be done? It seems that the coolant comes out of the valve of the protection group. This factor means increasing pressure in the system. Also, the system of fueling the system may not be closed or it is necessary to pump up an expansion tank. Tell me, because of what the pressure is constantly growing, and at the same time comes into effect the reset valve? On the display, a symbol of heating in the heating cycle of the device is issued each time. What to do? There is a malfunction of the thermal attewer of the heating circuit. The coolant is poorly circulating in the heating system. What is the problem if the wall.mounted gas boiler Ariston Clas 24 FF NG often turns off? For example, today Piezo ignition did not function at all. The prophylaxis of the device was done this week. What a malfunction? It seems that there are malfunctions in the smoke removal device. It is necessary to check the chimney. Incorrect operation of an element of ignition means a breakdown of its component due to a voltage jump or water fell into it. Please help clarify the situation with the chimney channel? Soon the second day, the reverse craving appeared, because of which smoke began to fall straight into the room. I made a chimney myself. It is a steel pipe. Perhaps in some ways there are flaws. The unit normally works for hot water supply, although at the time of turning on the heating there is a boil of water, and the device is turned off. What could be faulty, and how can you eliminate? We assume that the circulation pump has a defect, an electronic board, breakdown of a thermal attenter. At the same time, the filter mesh could clog. At the stage of hot water supply, the unit began to give out either cold or hot water in turn. I can’t figure out what it depends on. How to stabilize the heating of the coolant? Most likely, there are pollution in the heating system or it is necessary to clean the heat exchanger. There may also be a malfunction of the sensor that controls the pressure, or the circulation pump broke down. The main reason may be an incorrectly performed chimney configuration. There may be pollution of soot, which sharply limits its effectiveness. In addition, it is necessary to check the exhaust holes in the house. Installed and connected the gas boiler Ariston class 24 FF. The device sharply gains a temperature above 96 degrees, but then stops working on overheating. In the future, after its cooling, it goes into automatic launch mode. What is the reason? Overheating stop indicates a lack of coolant circulation. First of all, you need to control the position of the cranes of heating radiators. They must be left open. After that, an inspection is performed for clogging of the filter, and it is also recommended to make sure that the mud contains a heat.rated device. He performed independently commissioning this unit in March. After about five months, the device began to make a noise. I would like to know why in the boiler noise? Most likely, the heat exchanger has a scale. If the water has stiffness, then over time, a lime plaque will be deposited in the wall of the radiator tubes. We expect to connect the Ariston Clas X 28 Ff to the heating system. I would like to know how to properly launch such an unit into operation? For the correct launch of this equipment, subsequent operations should be performed. We connect the power supply of the device. Open a gas valve. Then we start a burning device. Then configure the desired temperature. We need to perform maintenance. Advise how to properly drain the water from the unit? In accordance with the instructions, such a procedure is performed in the following order. Disconnect the unit from the electric network. Overlapping the gase valve. We open the automatic air challenge. Completely open the drain crane. Next, collect the spilled liquid. In another case, you can drain water using a dumping valve. This component is located at the bottom of the boiler device. Please tell us how to diagnose a three.way valve? It seems to me that this part does not stop the opening. In heating mode, distant radiators cannot pump, although a pipe is heated in the DHW mode for heating under a boiler unit. You are right, you need to look at the 3-hide valve at the presence of hanging stem in an intermediate position. In turn, we recommend that you inspection. We operate in the dacha Evo 24 ff. Towed this evening without question. Currently 3 seconds after turning on, he began to go out. There is an assumption that he cannot deliver the coolant to the system. Tell me what kind of problem this is? A possible cause of this failure may be an electrode of ignition, which does not determine the flame, or a decrease in the circulation process. The other day there was a nuisance with such a model. During work, he began to whistle. Tried to restart it. it turned out, but he still whistles. Tell me what a problem is? Very often a strong whistle happens if the instructions are not adjusted to the pressure on the nozzles of the gas burner. It is required to check gas pressure adjustments and fix it if necessary. Water got into the gas boiler, and the unit began to function with problems. For example, if you set at least any temperature, but the heating cycle reaches exclusively to 26 degrees, and then it stops. Please tell me what could fail? If water is filled into an electronic block, most likely, it does not work correctly. We will advise you to reset it with a linear disconnection of the unit from the power supply. Then start again and test its serviceability. Put into operation 24 Ff System. Today, when starting for 10 seconds, the wick lights up, but the main burner does not support the flame, and the unit goes out. How best to solve this problem? Automatic ignition or problems with the burner probably broke. Just in case, you can check whether the phasing is correct at the time of connection to the electric network. Carried out in the middle of this year the installation of this model. About six months later, a failure arose in the work of hot water supply, but in heating mode it works normally. I wanted to turn on hot water, but the device only displays the temperature, but does not even think to warm. Tell me what the reason? There is probably a breakdown of a 3-running valve. It is required to change it. Explain what functions in the boiler you need a protective thermal attemptor? The safety thermal attemptor covers the supply of gas to the burning device when the water is overheated in the main heat exchanger. I need to rinse and clean the primary water heat exchanger on Clas X 24 CF. Explain what needs to be done in order to accurately remove it? The main heat exchanger is easy to remove from the device when using a conventional screwdriver. Below is the procedure for dismantling. Drain water from the unit using a descent crane. Then we empty the hot water supply system. Unscrew the fasteners of the main heat exchanger and get it from the frame. I performed on my own launch with a heating device. Presumably five months later, there was a decrease in water pressure in the unit. Often he drops it and stops working. precisely, it does not keep pressure at all. Why is this happening? If the device does not increase water pressure, a fuel tap may occur. Когда происходит отключение и давление воды упало до нуля, то имеет дефект 3-х ходовой кран. Tell me how to clean the filter for cold water? First, drain the water from the hot water supply contour. Secondly, unscrew the nut of the duct sensor. Then we dismantle the sensor and a filter from the cavity. After that we remove the accumulated garbage and dirt. The device at the time of the start of work and before that published a buzz, and at this time it makes noise much louder. At first, the sound was not heard for long, now it lasts much longer. It was not heard for long, I faced such a problem? The formation of an excess roar indicates the presence of mineral deposits inside a heat.exchanging device that does not warm the same due to the unequal thickness of the walls. The stronger the heat exchanger polluted, the more distinct the roar, and the heat transfer also decreases. The device works, but the system clearly does not circulate water. The pump acting on the return is noticeably heated. What could happen? Probably a filter-gryazevik was clogged or cranes closed somewhere, and this slows down the passage of the coolant. The circulation pump could still break. What the mountains cannot heat up from. water? Water is barely warm. Explain what the reason is? Problems can be sought in several directions. In case of damage to the temperature sensor, the sensor is required to replace the sensor. Perhaps the power of the power of the apparatus was lost on the heating of the water. From time to time we notice the cessation of flame during ignition. The burner is clean, the chimney is in order, there are no problems with a traction. What could be a malfunction? The device does not detect a spark due to a weak signal from the combustion mechanism. Try to diagnose the wire between the ionization sensor and the electrode. Obviously, it is necessary to tighten it. There may also be damage in the isolation of the sensor, which must be replaced.

Ariston boiler relay

Then, much later, analogues of the necessary relay on Aliexpress were found. This is the relay of OMRON G5NB-1A-E. or Panasonic ALD124 24 B. They are also for 24 volts, but this is how it has already turned out not a problem. The relay is made and look great, probably the original. So now I have some stock.

P.S I want to add about cashback, for a few small purchases I received 2.32. So it really works. Register and get a return from each purchase. About

For those who are interested in why, when the fan does not ignite, the gas boiler is not ignited, we read on.

Cleaning a gas boiler

Carry out regular cleaning with a brush, a vacuum cleaner of surfaces in the combustion chamber. a gas burner and the primary heat exchanger.

To clean the primary heat exchanger, it is better to remove it from the boiler:

  • Disconnect and empty the boiler.
  • Open the front lining of the combustion chamber.
  • Remove the electronics block and protect it from water.
  • Remove the brackets. clamps on the pipe of the feed and reverse braid fishing line (1).
  • Dissolve the upper pipe of the supply and reverse braid line (2).
  • Eliminate the heat exchanger (3) forward.
  • Clean the ribs of the heat exchanger from combustion products using a hard brush and a vacuum cleaner.
  • Install the heat exchanger in place.
  • Combine the pipes of the feed and reverse braid line (2).
  • Fasten the brackets on the pipe of the supply and reverse braid line (1).
  • Close the combustion chamber with a lid, install an electronics block in place.

The surface of the gas burner is cleaned of combustion products in place without removing from the boiler. For cleaning, use a hard brush and vacuum cleaner.

To remove the fan, you need to unscrew only one screw

Remove the fan from the boiler every 3-5 years, clean the impeller and other surfaces of dirt, lubricate the bearings with a few drops of oil. Do not wait for the noise from the fan becomes unbearable. Pay attention to the state of the gasket between the fan and the chimney.

The principle of operation of the circulation pump Wilo MTSL 15/5 he. 2

The main part of the pump is an electric engine consisting of a stator with several inductance coils to adjust the speed of rotation, and the rotor, which is integrated on the shaft with bearings.

When power is supplied to one of the stator windings, an electric field is created, which drives the rotor with a turbine. The turbine blades capture the liquid from the suction pipe and move it on the output pipe. In this way, the coolant is circulated along the entire heating circuit.

Consider the main reasons leading to the breakdown of the pump Wilo MTSL 15/5 he. 2.

Unstable voltage in the network

With low power, the pump engine slows down its work until a complete stop. With increased voltage, the coils of inductance occurs, due to which an interval circuit or the burden of the winding wires may occur.

Pollution of the pump mechanisms

At a liquid temperature of more than 60 ᵒ С turbine and shaft, a scale may form, which will inhibit the rotation of the motor anchor. The reasons for the jamming of the pump can be increased oxidation of moving mechanisms or entering foreign objects.

Poor.quality material of components

If the pump uses parts made of low.quality materials. Its resource is sharply reduced. For example, the shaft begins to jam due to the formation of a rust layer on the surface of the bearings, because they are made of bronze, which includes iron. Such symptoms are characteristic of a non.original model.

Incorrect operation of the device

Water through a working pump should constantly circulate at a certain speed. In case of violation of the movement of the coolant (the valve or the supply line is blocked, the system filter is clogged, etc. D.), the device will overheat bearings and inductance coils. This will lead to jamming of the rotor, a break or closing of the stator winding.

Wilo MTSL 15/5 he circulation pump. 2 cannot be used when there is no water in the pipeline. But since the double.circuit automatic unit of Ariston is equipped with fluid pressure sensors, the boiler will not turn on in the absence of water in the system or its low pressure.

Possible reasons

There are times when they purchased a new boiler, installed it and began to use it. But it begins to arbitrarily turn on and off. Of course, he must regulate his work himself, but there should not be frequent shutdowns. In this case, it is necessary to understand the reason. After all, this indicates the presence of any malfunctions. If the device often turns off and turns on, then its service life is significantly reduced due to the wear of working parts. And, therefore, the boiler will fail.

  • The power of the boiler is designed for a larger area than there is a room.
  • The circulation pump is installed incorrectly.
  • The boiler is selected incorrectly.
  • There is no thermostat in the room. The boiler is adjustable according to the temperature of the heat carrier.
  • The temperature range is indicated incorrectly.

The problem is simple, but sometimes because of it it is necessary to replace the gas boiler.

Repair and setting up the boiler Ariston Clas

The mode is used for proper analysis of combustion and calibration products for the maximum and minimum values.

  • If the boiler is in the “Winter” mode, the three.way valve is in the “TSO” position, and the burner is turned on even without a heating command.
  • Apparatus in the “Summer” mode:
  • in the absence of a command on the DIS, the device operates in the TSO mode;
  • In the presence of a command on the GVS, the device operates in the dowry mode.
  • Mode “Summer” → Obt.: 86 ° C; V.: 81 ° C;
  • Mode “Winter” → Obt.: 89 ° C; V.: 84 ° C.

In this mode, the boiler begins to supply hot water to the DHW contour faster.

For this purpose, high temperature is maintained in the primary circuit of the boiler.

The device goes into mode Comfort for each team on the hot water and supports it for 30 minutes. To get out of this mode, re.press the “C” button.

If the temperature sensor at the supply of NTC1 does not operate (a short circuit is open or there is), the transition to the “freezing protection” mode is carried out according to the NTC2 sensor on the TCA reverse, but in this case only the pump works (the burner does not turn on). The display does not display the designation of the freezing protection mode, but the code 1 10 NTC1 sensor errors with a short circuit or rupture of the chain.

The device goes into freezing protection mode, even if the NTC2 sensor does not work (a short circuit is open or there is), but in this case only the pump works (the burner does not turn on). The display does not display the designation of the freezing protection mode, but the code 1 12 NTC2 sensor errors. short circuit or chain rupture.

The device goes into freezing protection mode, even if there was a shutdown due to non-equipment of flame, error code 5 01. or blocking due to overheating, error code 1 01. But in this case, only the pump works (the burner does not turn on), and the display does not indicate the mode of protection against freezing, but the blocking error code.

In case of power outage, all settings are preserved in the device, and after the power restoration, it goes into the mode in which he worked before disconnecting.
