Home » Classification of gas boilers » Operating principles » Setting up Proterm gas boilers

Gas boilers Proterm are popular among consumers due to their reliability, European quality and reasonable price. Among floor-standing devices, the Bear series is known, and among wall-mounted devices, the Cheetah is considered the most universal line. Models with the letter designation MOV are equipped with an open combustion chamber, while MTV is equipped with a closed combustion chamber. Let's look at how to configure Proterm gas boilers.

Heating modes Proterm Cheetah

The gas boiler Proterm Cheetah can operate in several modes:

“Heating” - you need to press the MODE button once, and the display will show the “radiator” symbol with the current pressure value in the heating system. While in this mode, the unit works only to produce heating, while the hot water supply is turned off.
“Summer” - activated by pressing MODE twice. The pressure indicator in the heating system will appear on the screen along with the “tap with a drop of water” symbol. In this mode, the boiler only works to supply hot water.
“Vacation” - press the MODE button three times, and the OFF symbol with a pressure reading appears on the screen. In this mode, heating and domestic hot water do not work, but all protective functions of the device are active.

The desired heating or hot water temperature can be adjusted using the “+” and “-” buttons. The setting is carried out as follows:

The DHW temperature is adjusted as follows: after pressing the “+” or “-” button, the “tap with a drop of water” and “ºC” symbol starts flashing. The required temperature value is set in the range from 38ºC to 60ºC.
The heating temperature is also set using the “+” and “-” keys. After pressing one of them, click on the MODE button, a flashing “radiator” and “ºC” symbol appears. Then use the “+” and “-” keys to set the optimal coolant value in the range of 38-85ºC.

The operation of the Proterm Gepard gas boiler without thermostats is not very economical. To achieve maximum savings, it is recommended to purchase a room thermostat.

How does Proterm Gepard work when connecting thermostats?

When the Protrem Cheetah gas boiler operates without a room thermostat , heating of the rooms depends on the coolant temperature settings.

When connecting a Proterm thermostat , it becomes possible to set the desired heating temperature. It must be such that the unit can maintain it, regardless of the outside temperature. The controller will only control heating within the selected range.

Note! In the room where the room regulator is located, radiators cannot be equipped with thermostatic valves.

The Proterm unit with a two-position regulator is capable of maintaining a given heating temperature. The boiler will receive a signal to turn on or off depending on the temperature in the room in which the regulator is located.

When connecting a continuous regulator , the power will change smoothly to maintain the set room temperature.

The room regulator will control the temperature in the room and send a signal to the unit to turn off if the heat level has reached the set value or to turn on if the temperature decreases.

The most modern and accurate is equithermal regulation . This is done by a thermostat with an outside temperature sensor. When such a device is connected to a gas boiler, the latter will regulate the temperature of the coolant depending on the conditions outside.

If the operation of the unit is controlled by an equithermal regulator, it is not recommended to set the maximum coolant temperature - this will significantly reduce the efficiency of the system.

Features of the “Proterm” “Gepard” boilers

The units of this modification are double-circuit, each with an individual heat exchanger: for heating - made of copper, and for hot water - stainless steel. The design of the boiler allows the water to heat up in just 2 seconds. The MTV model is equipped with a coaxial flue gas exhaust system, so no connection to the chimney is required.

For your information! The latest modifications are equipped with a heavy-duty composite hydraulic module to service the two-stage pump and plate boiler.

The “Proterm” “Gepard” boiler is equipped with a functional display of the technological process control unit with diagnostics of system failures, adjustment of thermal modes and a history of emergency failures. Safe operation of the unit is ensured by protective functions against freezing, overheating of the coolant, control of the gas-air path of the boiler, including flame breakage. The eBus built into the automation integrates the operation of the unit into complex heat transfer processes with Protherm regulators.

Preparation for start-up and start-up of the boiler.

Preparation and first start-up of the boiler are part of putting the boiler into operation and should be carried out by a specialist from a service organization. However, if you are the owner of such a boiler, then you need to be able to turn this boiler on and off and understand its operation.

Proterm 20-60 PLO

Protherm 20-60 PLO

The Proterm 20-60 PLO gas boiler is a high-quality and reliable boiler, but it is not very convenient to start compared to its brother, KLOM. This boiler uses a wick to start the burner, which in turn is ignited by a piezoelectric element. So, about everything in more detail.

The article describes the procedure for turning on the Protherm 20-60 PLO boiler, but this is not the “first turn on” carried out by the service organization. This means that there is already water in the heating system, the required pressure is maintained, all the necessary taps and valves are open, the gas supply is ensured, and the boiler is plugged in.

First you need to find the FIRST control panel under the plastic cover. Make sure that the switch (4) is turned on, the indicator (3) is not blinking, and the readings on the sensors are normal.

Next, you need to open the front metal cover and find the SECOND control panel. On it, you need to set the boiler thermostat (9) to approximately the middle, check the switches (6) and (7), and, if necessary, check (5) and (8).

Next, you need to open the front metal panel and find the gas valve and its control buttons. We need to light the fuse.

This is done once, after the boiler has been turned off. This often happens when the gas alarm in the boiler room goes off. For example: when there is a power outage in the house, the gas supply in the boiler room may be turned off, which leads to the boiler stopping and the wick going out.

Find the necessary controls: – Piezo igniter button to supply a spark (shown in GREEN in the diagram); – Burner control knob (shown in RED in the diagram); – Inspection window (shown in YELLOW on the diagram);

The gas valve control is simple. To start the boiler, you need to turn the handle to the desired position and simultaneously press the piezo igniter until the wick lights up. Please note: at the end of the handle you can see three modes:

1 mode Turn off the burner and wick

Mode 2 Launching the wick using a spark

Mode 3 Starting the main burner

Stepped power setting

Depending on the boiler model, the number of power levels varies. The widest range of regulation is available for Skat boilers operating from a single-phase network and having a power of 6 and 9 kW.

Reviews

User reviews of Proterm Skat electric boilers are positive. But not everyone can understand all the features of electric heating equipment, expecting more from it. You will find detailed information in the reviews.

When we bought a summer cottage, we didn’t even suspect that we would want to live on it almost permanently. We often come here in winter, so last year we decided to install normal heating in the house. Having installed a Protherm electric boiler, we spent a lot of money, but we received the long-awaited warmth. What can we say? It heats properly, we don’t even touch it, there are no leaks or breakdowns, nothing rattles, stinks or rattles. Yes, the bills for electricity turn out to be substantial, but this is the only way to heat the dacha, the nearest gas pipe from which is 10 km away. But it is simply impossible to heat with wood and diesel fuel - the system will freeze while we are in the city.

I work as a sales consultant in a store and sell heating equipment. There are many small settlements near our city that still do not have gas. Therefore, the sale of Protherm electric boilers brings the store good money. Why Protherm? Yes, because this company makes really excellent devices, and not poor crafts in the form of metal pipes with wires. Excellent layout, built-in automation, excellent appearance - what more does the consumer need? Yes, the price is a little steep, especially due to the unstable dollar exchange rate, but this is the only solution for those who do not want to bother with heating, but just want to warm up in their country house.

When I was choosing an electric boiler, I wanted to take a simple Russian model. The devil pulled me to buy a Proterm boiler. I didn’t see the vaunted efficiency, but I spent a lot of money for the equipment. The good news is that I didn’t have to buy a harness, at least I saved on it. So, electricity bills turn out to be astronomical, despite the fact that the winter this year was relatively warm. What will happen then in the cold winter? No, there are no complaints about the equipment itself, it works well. But why do the manufacturer and sellers talk about some mythical efficiency? Here are the gas ones - yes, economical. But what I saw in the bills for electricity was pure horror.

When purchasing any heating equipment, the user receives instructions. It describes all the points that relate not only to the installation of the unit, but also to its operation. The Proterm Skat 9 kW boiler is no exception. Of course, for some reason the instructions were lost, then it will not be possible to start heating the house. After all, an electric boiler needs to be configured correctly. There are certain rules for the installation and operation of an electrical unit. They must be respected. Otherwise, the equipment will not work correctly.

Components for boilers Proterm Skat

When purchasing a boiler, in addition to it, the manufacturer offers various accessories to expand the functionality.

Thermostats

For boilers Skat, Proterm suggests using three types of room regulators: Exabasic (article 6195), Exacontrol (article 0020159367) and Exacontrol 7 (article 0020170571).

Room thermostats for boilers Protherm Skat

The simplest Exabasic model has only a rotary switch for setting the temperature, Exacontrol is already equipped with a display and has mechanical controls. Modification number 7 - has a weekly programming function.

Temperature sensors

To adjust the operation of the boiler relative to the temperature outside the window, you should purchase an outdoor temperature sensor (article 0020040797).

External temperature sensor for Protherm boilers SKAT

In the retail network, its cost varies around 2,000 rubles (38 euros).

Detailed scheme for starting the PROTERM PLO boiler

Set the gas valve handle to the SPARK position to be able to light the wick. Set the position as in the picture below:

Mode 2 Launching the wick using a spark

Next, with one hand we press the gas valve handle in the indicated position, and with the other hand we press the piezo igniter button to create a spark. One press of a button - one spark. You need to be prepared for the fact that it will be necessary to knock out a spark several times before the igniter lights up. This can be heard or seen through the viewing window. But don’t rush to throw your hand off the gas valve handle. To prevent the wick from stopping burning, you need to wait 10-30 seconds before the flame is detected automatically.

Mode 3 Starting the main burner

When the wick is operating stably, the gas valve can be switched to MAIN BURNER mode. To do this, you need to press the knob and turn it further - along the arrow to the pointer with the flame. At this moment, the main burner should LIGHT and the boiler will go into operating mode.

Features of installation of Protherm gas equipment

Installation of Proterm gas boilers, like installation of any heating equipment, has its own characteristics. Depending on the type of boiler, the consumer will have to take into account some nuances that affect the safety of operation and energy efficiency of the equipment.

General requirements for boiler installation

When installing Protherm wall-mounted gas boilers, the minimum permissible distance between the boiler, ceiling and floor must be observed. When hanging the boiler, there should be at least 50 cm to the ceiling, and 80 cm to the floor.

If the wall on which the boiler is installed is made of flammable materials, it must be additionally equipped with a metal sheet with a thickness of at least 3 mm.

You should first pay attention to the wiring. The cable from which the Proterm boiler will be powered must be stretched without bends or creases. Please note that the wiring will only ensure the operation of gas equipment; you cannot connect other equipment to it. Provide the boiler with grounding.

The diagram shows a standard grounding diagram for a gas boiler. The grounding circuit can be arranged on your own

After unpacking, flush the pipes to remove any dust from all cavities before installation. Dirt can clog the Protherm boiler system, so pre-cleaning is mandatory.

If the choice falls on a heavy floor model, it is recommended to make a screed or lay concrete slabs at the installation site. It is important that the finished platform is leveled strictly. We provided more technical standards and requirements for the installation of floor-standing boilers in our other article.

If the model requires connection to a chimney, be sure to check the draft before connecting to the system. Additionally, it is worth fully inspecting the permeability of the chimney and cleaning its shaft.

Gas units produced by a Slovak company differ in type of installation and power:

Wall-mounted boilers have less power, but are significantly cheaper. At the same time, the characteristics of the equipment make it possible to fully heat a private house.
floor-standing gas boilers have greater productivity, are more expensive, and take up significantly more space during installation. A separate foundation may need to be poured prior to installation. Therefore, the models are less popular among households, but are still in demand among owners of large houses.

Below we consider in more detail the popular series and models of gas boilers.

Lines of wall-mounted gas boilers of the brand

Due to their attractive price and relative compactness, wall-mounted boilers are in great demand. Protherm produces several lines of equipment to create an efficient heating system in a private house or apartment in a multi-storey building.

In the offices of official representatives, you can get acquainted with the plant’s product lines in a comfortable environment, look at the technical specifications and, if necessary, receive professional advice

Three lines are in demand on the domestic market.

The Panther series includes six performance models with a power of 12-35 kW, labeled KTV, KOV and KTO. A number of KTVs are equipped with a system for forced removal of combustion products, so they are suitable for rooms without a chimney. Models of the KOV series are connected to a chimney with a natural outlet.
The “Lynx” line of boilers is represented by three models with a power of 24 and 28 kW with a system for forced removal of combustion products.
Double-circuit Gepard boilers with a power of 23 kW include models 23 MOV and 23 MTV. The modifications differ in the removal of combustion products: in 23 MOV it occurs naturally, in 23 MTV it is forced.

The unit must be selected based on its potential performance, heated area, and installation requirements.

Series of floor-standing gas boilers Protherm

Products for floor mounting have serious power, so they are used for heating large rooms with a high level of heat loss.

Three popular lines of Proterm equipment cope well with the assigned tasks and have their own characteristics that should be taken into account during installation.

Popular models

The company's product range includes electric and gas heating equipment of various capacities. Among the most popular modifications:

Cheetah

The wall-mounted version is equipped with a stainless steel heat exchanger. This is a 23 kW model. The operation of the system is automated and can be carried out using a temperature sensor.

Scat

An electric boiler is a reliable heating equipment for a home, cottage or apartment. Skat models are characterized by high performance and ease of maintenance. New from 2022 - built-in storage boiler. The single-circuit boiler has a self-diagnosis function; it is completely protected from overheating and pump jamming.

Removing air pockets in the system

Simply filling the heating system with water is not enough; in order to fully start the heating system, it is necessary to release the accumulated air from it. Most modern heating boilers are equipped with an automatic air release system, but, as a rule, they work inefficiently and therefore, at least from the main components, it must be removed manually. Starting the heating system involves eliminating air pockets in the radiators and circulation pump.

It's better to start with batteries. To remove air pockets, a Mayevsky tap is usually installed on them. We open it and wait for the water to run. Did you run? Let's close. Such manipulations must be done with each heating device separately.

How to start a boiler with your own hands photo

After the air is removed from the batteries, the pressure in the system will decrease and the pressure gauge needle will drop. At this stage of work, the solution to the question of how to start the boiler involves re-filling the system with liquid.

Now, the most difficult thing is that starting gas boilers requires bleeding air from the circulation pump. To do this, the boiler needs to be disassembled a little. We remove the front cover and look for a cylindrical object with a shiny lid in the middle, which has a slot for a screwdriver. After we have found it, we put the boiler into operation - we supply it with electrical power and set the water heating controls to the operating position.

Relieving air from the circulation pump when starting the boiler photo

The circulation pump will immediately turn on - you will hear a faint hum and loud gurgling and many incomprehensible sounds. This is fine. As long as the pump is aired, it will be so. Take a screwdriver and slowly unscrew the cap in the middle of the pump - as soon as water starts seeping out from under it, screw it back. After two or three such manipulations, the air will come out completely, the strange sounds will subside, the electric ignition will work and start working. Check the pressure again and add water to the system if necessary.

Basically, that's it. While the system is warming up, you can begin to study the instructions in detail (if, of course, you have not already done so) and start debugging the system that involves starting the boiler. Everything is simple here - the batteries closest to the boiler need to be screwed on, and the ones farther away need to be turned on to their full potential. This debugging is carried out using control valves installed on the supply connection pipe to the heating radiator.

Advantages and disadvantages of Proterm Skat boilers

Most of these disadvantages and advantages are inherent in most boilers operating on electricity.

Pros of Protherm Skat boilers

High efficiency
Easy to install
Unpretentious in maintenance
Eco-friendly
Doesn't require much space
Silent operation

Disadvantages of Skat series boilers

High cost of electricity
Dependence on power outages

Sometimes electric boilers are credited with shortcomings that are no longer relevant or were obviously incorrect; let’s look at some of them:

The boiler power is not enough to heat a house larger than 300 m2

This statement is incorrect, due to the fact that Skat boilers can be connected in a cascade to increase the heated area, if there is a shortage of 28 kW.

Frequent replacement of the heating element

Due to the fact that the heating medium is heated using a heating element, many believe that such a heating element will not last long, but you need to take into account the quality of the heating element itself and do not forget that it is not water that circulates in the system, but a coolant.

Remote thermostats and choosing a location for their installation

A significant advantage in favor of electronic models can be the presence of remote thermostats.
In this case, adjustment occurs using a separate panel, which can be placed in any place convenient for you. The choice of location for a remote thermostat in any building should be guided by safety and comfort parameters. It is better to place the thermostat out of the reach of children; it is also worth considering factors that can damage the device. Currently, electronic thermostats with a Wi-FI module are also produced. Data from thermostats can be transferred directly to your smartphone using special applications created by developers. Using such applications, you can adjust the temperature remotely. Such models will fit perfectly into the “smart home” system.

How to put the Protherm Skat boiler into operation

To start the boiler, you must follow the instructions below.

The electric boiler is installed by a specialist in accordance with the design documentation.
Before starting the equipment, a professional provides instructions on the principles of operation of the electric boiler.
Before turning on the boiler, you should connect to the network , open the taps on the heating circuit and note the pressure level (1 or 2 bar).
The display shows the settings options.
The required temperature of the heating system, when connecting a boiler - water supply circuit, and power is set by the consumer himself.

When the pressure is low, the “bar” light starts flashing on the display. To correct the situation, add water to the system. If in this case the pressure decreases, then you need to contact a specialist.

If you need to stop the operation of the Protherm boiler for a long time, you need to disconnect it from the power supply and turn off the taps. If shutdown is necessary in winter, the system must be drained to prevent freezing.

How to care for a Protherm electric boiler? Do not use abrasives or chemicals. It is better to wipe the surface of the case with a damp cloth, and then dry the surface.

Any malfunctions are indicated on the display by an error code. The code numbers are located and deciphered in the product passport.

If serious problems occur, for example, the heat exchanger is frozen or water is dripping from it, the electric boiler must not be connected to the power supply. You need to wait for a specialist who will diagnose and carry out high-quality repairs. Replacement of parts is carried out only using original spare parts.

So, dear readers, you have become acquainted with the alternative type of heating Protherm Skat. When gas and solid fuel are out of reach or you are a stickler for cleanliness, an electric boiler can be a good help.

Instructions for connection, setup and operation

Before starting operation, the boiler must be installed and configured.

Primary requirements:

installation of the boiler and all auxiliary equipment is carried out in strict accordance with the design documentation, SNiP requirements and manufacturer’s instructions;
The installation is located in a specially equipped room. For models with open fireboxes - in separate buildings, and for closed ones, they can be installed in residential (not sleeping) premises;
The installation and commissioning process is carried out by specialists from a service organization with certificates from the equipment manufacturer. Self-installation may void the repair warranty for the unit.

List of mandatory maintenance works:

checking the gas-air path for tightness and absence of damage - once a year;
checking the general condition of the boiler - once a year;
cleaning the surfaces of the boiler and smoke channels - once a year;
inspection of the boiler for corrosion damage, deformation and soot clogging - once a year;
checking the gas pressure at the boiler inlet once a year.
checking the condition of electrical power equipment - once a year;
perform a test run and remove air - once a year;
checking the condition of the expansion tank - once every 2 years;
checking the burner for damage - once every 2 years;
Cleaning the mesh filter at the cold water inlet - once a year.

Setting up and adjusting the power of a gas boiler when operating on antifreeze

Traditional antifreezes based on ethylene glycol or propylene glycol have a higher viscosity compared to water. As a result, the movement of coolant through the boiler heat exchanger slows down. In addition, antifreezes have a lower heat capacity. All this leads to the fact that the antifreeze in the boiler heat exchanger, which is designed for water, at maximum power instantly heats up to the boiling point and boils. Boiling of antifreeze, as a result of local overheating in the heat exchanger, manifests itself in the form of loud noise, roaring and gurgling.

A gas boiler, when operating on antifreeze, can only operate at a reduced power, lower than that specified in the boiler instructions for water.

To slightly increase the power of a boiler running on antifreeze, it is recommended to dilute the antifreeze with water and also increase the pressure of the circulation pump.

For example, for heating systems with wall-mounted gas boilers, it is recommended to dilute the contents of the original packaging with water in a ratio of 1:1. As a result of diluting the antifreeze, the temperature at which crystallization begins will increase from -30 °C

to minus 10 °C.

If the crystallization temperature of diluted antifreeze is not satisfactory, then select another antifreeze.

In any case, to prevent overheating of the heat exchanger, in the settings of the service menu and gas valve it is necessary to limit the boiler power in heating mode (in lines d.00 and d.52 of the service menu), and also set the maximum coolant temperature no higher than +70 °C, (in line d.71 of the service menu). It is also recommended to increase the response pressure of the bypass valve on the boiler (how? - read below).

The boiler manufacturer usually gives its recommendations on the choice of antifreeze in the operating instructions. So, for Protherm gas boilers, the instructions say: “It is not recommended to use non-freezing liquids in heating systems with Protherm equipment installed. The use of non-freezing liquids entails a decrease in the efficiency of heat exchange, higher surface temperatures on the walls of the heat exchanger and its rapid wear, an increase in the corrosive effect and viscosity, corrosion of gaskets and fittings, both in the boiler itself and in the heating system. A boiler malfunction associated with the use of non-freezing liquids will result in a warranty denial.”

What's wrong with too much power?

Let's look at setting the power of a gas boiler using the example of a double-circuit device Protherm Gepard 23 MTV. This model is an analogue of the Protherm Panther unit. The same manufacturer that produces Protherm gas appliances produces Vaillant brand boilers in another production facility. Their price is much more expensive, since they use higher quality components. In design and settings, Vaillant gas devices are very similar to Protherm models.

The operating instructions say that the useful thermal power of the Protherm Gepard 23 MTV boiler is adjustable from a maximum of 23.3 kW to a minimum of 8.5 kW. In production, the units are set to a power of 15 kW.

It is good if the heating system to which the gas boiler is connected has a power within the capabilities of the burner device, in our case - from 8.5 to 23.3 kW. But what if the existing radiators require less performance?

For example, let's take an apartment with an area of 50 m². For its heating there are radiators with a thermal power of 4 kW. The installers installed a gas boiler, but did not set the appropriate power. A 4 kW heating system will not be able to accept the installed unit performance of 15 kW. The large difference between the produced and the required indicator makes it impossible to automatically adjust the boiler. Then you need to adjust the device yourself.

Note! Experts categorically do not recommend installing a gas boiler whose power significantly exceeds the required one. This leads to cyclical operation of the unit and its rapid failure.

The characteristics of the gas boiler Protherm Gepard 23 MTV indicate that the efficiency of the device when operating at full thermal power is 93.2%, and at minimum - 79.4%. If the unit operates at a capacity of 4 kW, its efficiency will decrease even more. It turns out that almost a quarter of the thermal energy will “fly down the drain.”

Cyclicity of a gas unit and its consequences

Cycling or “clocking” of a gas boiler means that the burner, after being turned on, quickly turns off when the liquid reaches a given temperature in the pipe at the outlet of the unit. But the batteries do not have time to warm up. After a short period, the circulation pump pumps cold water from the heating system into the unit circuit, and the burner turns on again.

Another difficulty lies in the fact that low-power heating pipes have a smaller diameter and higher hydraulic resistance; accordingly, the coolant flows in them more slowly. If you heat the liquid in the heat exchanger with high power, it will reach the set temperature very quickly and the burner will turn off. At the same time, the rest of the water that did not have time to reach the burner will remain cold.

Automation without human intervention will not be able to react to the situation and adjust the optimal power of the device.

Note! With the correct settings of the heating system, the temperature difference between the inlet and return should be no more than 15ºC. Cycling of a gas boiler significantly reduces the service life of the unit and increases fuel consumption

It is known that the components suffer the most wear at the moment of switching on. Also, when ignited, a maximum portion of gas is supplied to the burner, most of which evaporates into the pipe. Frequent re-ignition of the burner further increases fuel consumption and reduces efficiency. To avoid this, it is necessary to adjust the power of the unit, that is, to equalize the performance of the gas boiler and heating system

Electric boiler automation Protherm

What can automation do?

Performs a function such as equithermal temperature control in the heating system.

What it is.

This is regulation of the heating of an electric boiler depending on the outside temperature. Naturally, to perform this function, an outside air temperature sensor must be installed in the electric boiler circuit.

If you use the equithermal control function, for example, when it is zero degrees outside, the temperature of the heating water will not exceed 50 degrees Celsius.

Indeed, why “fry”, heat at full power if it’s warm outside?

At -10gr. the electric boiler will only heat up to +62-63 degrees no more. All this is selected in the settings using special equithermal curves; more details can be found in the boiler operating instructions.

Further, the automation can maintain the set temperature in the range from +25 to +85 degrees - whatever number you set in the control panel, this temperature will be maintained.

You can also adjust the boiler power.

Let’s say the power of a 14-kilowatt boiler is set to 7 kW, then in any case the boiler will not turn on at full power and will be limited to a power of 7 kilowatts.

Automation allows the use of an electric boiler in conjunction with a load relay.

A special relay is installed and when the load exceeds the permissible limit (for example, a washing machine and an iron are turned on at the same time), the relay gives a command and the electric boiler automatically reduces its power.

When the load returns to the permissible limits, it will increase the power.

It is very important that the load is turned on smoothly and gradually. . Even if, for example, you immediately set the full power in the settings, the heating elements will still turn on gradually

Even if, for example, you immediately set the full power in the settings, the heating elements will still turn on gradually.

First one heating element will turn on, then the second, then the third, etc. This is specially programmed so that there is no sharp increase in the electric current in the network when the Protherm boiler .

The heater switches off smoothly too. Therefore, when the electric boiler is operating, there are no sudden abrupt changes in the electric current.
