Wireless thermostat for a gas boiler: description, principle of operation, main types and connection. Room thermostat (temperature controller) for gas boiler

Crap! what kind of village, what kind of electricity is missing? Where is it written that in a settlement where there is no electricity at all?

You are like small children, that you need to chew everything verbatim.

"Well, call the unreasonable dad, that's why we are here. And what is the forum strictly for specialists?

"Well, it is understood that at some point there is no electricity. Temporarily not, periodically not, interruptions in the supply of voltage, a drunk electrician hanged himself on a pole, the dam burst, they turned it off for non-payment, local bastards stole the wires. Is that clear?
And where does it have to do with the villages with Ilyich's bulbs, if the conversation was generally on a third-party topic. "Heard a ringing, but did not understand where he was." The conversation was about installing an electrically dependent wireless thermostat on a non-volatile boiler. And the question was specific, when there is no electricity,

"I don't remember what"

And not questions about the biography of the rural hinterland or housing and communal services in some abstract village. What did you even want? To assert oneself or to introduce some new idea into the controversy?
Installing a non-volatile boiler does not mean a constant lack of electricity in the house, but a periodic one, but such a periodic one that it’s already sick of it. And there is neither desire nor money to spend money on a third-party source of electricity. So they make a non-volatile (gravitational) heating system with the installation of a non-volatile gas boiler."

Why do you think so? The reasons are different. Mine: built a house a long time ago. Then the EC was the only possible one. And now everything suits me very much

"You can pervert and put a circulator on the bypass at the outlet of the boiler. There is electricity-forced circulation, no-natural. But I wonder how such a chip will work with a remote electrically dependent wireless thermostat. Leave the batteries alone. The receiver is powered either from the mains (into a socket ) or through the same wires through which the control signal passes from the board to it. The electricity was turned off and the boiler simply did not start. The control circuit is open."

So what? It's OK. In winter, our electricity is turned off very rarely and no more than an hour

"But a special wired room thermostat with gold-plated contacts has electricity, no electricity."
And here is the question?

Room regulator PROTHERM membrane with gold-plated contacts (TLO) 230V, 50Hz 1568
Article: 36426

Slovakia

"He was made for this boiler.
And now pay attention - gilded. To control the boiler remotely by room temperature we are in a circuit (in a gap) of a multiple thermocouple and install a thermostat. So even a simple potential-free thermostat that does not have gold-plated contacts can give out such resistance, especially at the moment of switching, that a signal of 820 mV from a multiple thermocouple will clearly not be enough to overcome it. Consider the circuit open.
By the way, all thermostats installed in the boiler also have gold-plated contacts and for this very reason. Switching should be of high quality, and losses should be minimal.
Well, tired of just painting the same things a hundred times. "

This is clear. Tired. Tired. IT HAPPENS. WOULD NOT ANSWER.

Therefore, only specifics are given out, and the questioner begins to be smart, taking the question he asked in a completely different direction. Well, they don't get it. specific example, he needs the issue to be covered volumetrically, in space and time.
So that

Well, how else? Why would I ask then? I'm not always fond of heating.

Room thermostat for a boiler, this is a device that controls heating depending on the temperature in the room, and not on the temperature of the object being heated (as, for example, floor thermostats). Programmable thermostat - allows you to set the temperature in the house depending on the time of day, day of the week. Wireless - this is when you do not need to pull wires from the basement, where the boiler is most often installed, to the living room.

So why saving? But because in most boilers there is only a knob for regulating the temperature of the coolant. And that's it. Those. setting the temperature of the coolant in the heating system, for example, 50 ° C, we get the temperature in the room 24 ° C (selected empirically), and even then, depending on the temperature outside. And if it gets warmer and the house stops cooling down, you will have to run to the basement and turn down the power. an extra degree in the room is not comfortable and most importantly expensive. And vice versa - it got colder outside the window, the walls cool faster, run to the basement again, “add a degree”. With all this, the boiler operates in a constant on / off mode (which is not entirely good), maintaining the temperature of the coolant (and not in the room), and it does this often, since the coolant in the system cools down much faster than the air in the room.

In autumn / spring, when the weather can change dramatically during the week, heating the room by an extra 1°C leads to an extra excess gas consumption (I got 1°C ~ 1 hour of full power operation, which is 2.7 cubic meters of gas). The room thermostat, when the set temperature in the room is reached, stops heating completely and waits for it to fall (by 0.5 ° C), and then turns it on again. At the same time, the maximum efficiency of the boiler is possible only at maximum power. Those. the higher the temperature in the pipes, the more return we get from each paid cubic meter of gas. Here.

Why not WiFi? Yes, I thought about buying Nest, Honeywell, and the same Salus i500. But there is one small feature. They need Wi-Fi there only so that the thermostat connects to the Internet, “logs in” on the manufacturer’s server, on which the user, through the “web interface” or “mobile” application, will set parameters and observe beautiful graphics saving money. I did not find one that could be controlled by connecting directly to the IP address (as I do for example with a satellite receiver, TV, router, NAS and wife). Give everyone internet. And if the bourgeois disconnect us from their Internet, and if a drunk tractor driver breaks the telephone cable, and if he forgot to “put” money, and if hackers “put down” the server or my account is hacked and “fried” for my money. Too many "ifs" for an extra $50-$150, the only acceptable option is to do it yourself on, but this is in the plans.

Why wireless SALUS ST 620 RF? Well, my repair is almost completed and the extra wires along the wall would not be entirely appropriate. This is a model for Europe, but our boilers do not need, as in America, 24v (and troubles with a 220/24 power supply and a relay), NC (Normally Closed) terminals are enough.

The picture is from the English instruction, because. in the Russian-speaking one, she “moved out” and 2 wires are simply not visible.

Yes, and on the local market, mainly Salus and Auraton, the price really bites - from Belarus to Russia.

So what has arrived

Graceful "pimple" from the best English manufacturers


Slightly crumpled corners of the box made of fairly thick cardboard.


Everything is fine inside

dismemberment

Receiver. It is connected directly to the boiler (diagram at the beginning) with wires.

Transmitter (aka programmer). Hung in a heated room. It has on board a temperature sensor and an MSF 60 KHz module for adjusting the GMT time (above, wrapped with copper wire).

Backlight:

Installation work:
We remove the front panel of the boiler (I have Alfacalor made in Belarus, or rather honestly stolen from Italians)


Here is this black jumper, thanks to which the boiler works all day long, with periodic stops, heating the coolant to the set temperature.


Instead, we hook a 2-wire cable,


the second end of which is connected to the contacts COM and NC. We supply 220V and 0 to L and N, respectively.

There are 2 switches on the front panel. Using the top switch, you can set the “manual” mode if something happened to the transmitter (it burned out, broke, the batteries ran out), and then the relay will work in one of the three modes set by the bottom switch: On (Normally Closed - the boiler “threshes ”constantly), Off (Nomally Open - the circuit is broken, the boiler is not working), Cycle (4 minutes “closed”, 11 minutes “open”).

We return the front panel of the boiler to its place and turn the coolant temperature regulator so that it heats up to 75 ° C-80 ° C.

We press the SYNC button in the “receiver” with a paper clip, having previously selected the synchronization mode on the “transmitter”, and go to hang the latter on the wall to make it beautiful.

Interior. Aesthetics.
Hang away heaters, stoves, fireplaces, etc., which may affect the readings of the built-in temperature sensor.

On the right is the child lock button if you reach it.

Principle of operation:

Modes:
1. 7 days (i.e. different settings for each day). For convenience, there is a function to copy the settings for the next day.
2. 5+2 (Mon-Fri, Sat-Sun)

6 programs (settings) for each, by default like this:

Those. at 6 am the thermostat commands the boiler to start heating the water to 75°C until the room temperature reaches 21°C or 08:00 (because the heating system is inert, it is not known which will come first).
At 08:00 the thermostat will “break” the circuit, the heating and the pump will turn off, and turn on again at 11:00 and so on, 6 programs per day ...
Because I have cast iron batteries, the heating rate of the room did not exceed 1 ° C, it cools down a little more slowly, I set the following mode - at night 17 ° C, in the morning 20 ° C, in the afternoon 17 ° C, in the evening 21 ° C. I shifted the time for the weekend, taking into account the fact that there are more people, and drunk people sleep longer.

Peculiarity.
In the settings there is a PWM mode (pulse width modulation). But this is for electric underfloor heating, I guess.
It was nice to know that this model has such useful thing as time adjustment. It's like CASIO - waveceptor, Atomic clock in our opinion. Preliminary acquaintance and performance check took place in the apartment panel house, the exact time signal was “caught” only at night, when the “transmitter / programmer” was lying on the windowsill. The time was synchronized according to Greenwich Mean Time, i.e. the clock is 3 hours behind. No signal was received in the center of the room. “Well, okay,” I thought, in the center of the room it doesn’t catch and it’s not necessary, why do I need GMT if I can’t set the time zone. But in brick house the exact time signal of the radio station was received everywhere - in the center of the rooms and even in the garage. There is nowhere to hide from him. Here it is necessary to either remove the cross, disable this function, or put on the panties to change the firmware.
But the salus-tech.co.uk support severely broke me off - they kindly answered by e-mail that given function does not turn off and +3 hours is impossible to do.
I made a plate based on the default one (see above), and simply added the column "time -3" and subtracted 3 hours for programming convenience.

There are simpler models
ST320RF - a program for a day, i.e. every day the same thing.
ST620 - wired
ST620WBC - wireless, the receiver is plugged into the native connector of BAXI boilers

Video of work (not mine)

Results:

"+" No need to drag wires, spoil the interior
"+" Touch control
"+" Time synchronization works up to 30° East longitude 50° North latitude. Liked the review +43 +101

calling card of this English firm is the development and production ready-made solutions in the field of control of heating systems and in air-conditioning systems.
The devices manufactured by Salus Controls are used as: thermostats for heating boilers, underfloor heating systems, radiators, fan coil units, and also as thermostats for controlling circulation pumps.
programmers often called thermostats with programming functions, although this is not entirely true, because. all Salus temperature controllers have a built-in device of this type with a certain functionality depending on specific model: programming energy consumption, water supply, control of various sensors, etc.
The design of thermostats is based on locking and regulating mechanisms, which receive commands from the control unit, which, in turn, receives data from various sensors: thermo, pressure, humidity, temperature, etc. Based on the data from these sensors, control is carried out heating boilers, servo drives, valves, etc. Electronic thermostats are usually equipped with built-in programmers, with which you can set the climatic parameters that are comfortable for you. Using a heating control system helps save big number energy resources.
It is recommended to install Salus thermostats in the same room as the heaters, at a height of about 1.5 m. unnecessary problems, because most of the devices are easy to install and have a friendly interface. Depending on the configuration, SALUS Controls thermostats have additional features: zone climate control, wireless control (including via the Internet), weekly programming, etc.
Salus temperature controllers can be operated in a wide temperature range from 0°C to +60°C, the main advantage of the company's products is precise air temperature control - up to 0.5°C.

Briefly about the popular models of SALUS Controls thermostats

"Hits" of sales in 2014 and 2015 is a programmable thermostat Salus 091FL and its wireless counterpart Salus 091FL RF

Salus wireless thermostats (daily and weekly)
carry out electronic control boilers not directly, as wired thermostats, but by transmitting a signal to the control unit (receiver) located next to the boiler. The principle is simple: the room thermostat, depending on the temperature in the room, instructs the control unit to turn the heat generator on or off. The signal transmission between the unit and the thermostat is carried out using a radio signal, so the user does not need to lay control wires between them, which saves on installation, materials, and also allows you to move the thermostat to a new location if necessary. The control unit directly closes/opens electrical circuit to turn on / off the boiler in operation. The thermostat is usually powered by batteries (on average lasts for a year), but there are also models powered by 220V. The maximum distance in the house from the unit to the thermostat is about 50 meters (this parameter may differ for different manufacturers).

Thermostats (thermostats) Salus, with a modern stylish design, control the air temperature in the heated (cooled) room in accordance with their settings and are suitable for heating control systems where boilers are used for electricity, gas or liquid fuel.
These are simple and convenient temperature controllers in the house with the possibility of weekly programming. Models of the Salus 091 series control the operation of a heating boiler or heating pump. The factory settings allow you to select the heat management mode in your home from several programs without bothering to adjust the thermostat. In addition to the 6 factory preset programs to meet the needs of most users, the Salus 091FL and 91FLRF thermostats have 3 customization programs. Programming is carried out according to the principle of 5 + 2 days, 7 days, on the days of the week, individually for each day of the week.
Salus 091FL and 091FL RF thermostats have the ability to manually set the temperature, and can operate in automatic, manual or safety modes.
And most importantly: thermostats allow you to save up to 30% of your heating costs at home or cottage!
And what is causing the savings? Here is a simple example: You have absolutely no need to support high temperature in the room where you sleep, because the air temperature is 5-7 degrees lower than usual. And in the morning, when you wake up, the temperature can be increased by several degrees. This is the problem that the Salus 091FL or 091FLRF thermostats solve, which you program with the necessary parameters, and they will maintain the set mode throughout the week.

Heating your home is a vital part of it. Efficient Management this system helps not only to save money on heating, but also to extend the life of the building itself, heating equipment. In addition, it is always more pleasant to be in a room with comfortable temperature. The thermostat of the gas boiler copes with these tasks, and the wireless thermostat makes it easier to control the operation of the boiler in the house. Let's see what kind of device it is, how necessary it is and how to use it.

The device is a small device that is connected to a gas boiler using terminals and wires. When it comes to a wireless device, data is exchanged over radio waves. Wireless kit consists of two blocks, one of which is installed indoors. It has a temperature sensor and an interface through which the desired temperature is set. It is equipped with a liquid crystal display and a keypad. The second is attached to the boiler with terminals. The blocks are interconnected by a radio channel.

Based on this design, it becomes clear why a thermostat is needed: temperature control in the room through the function of turning on and off the gas boiler when the set temperature is reached.

For comparison: when a double-circuit gas boiler is installed in the house, the system is guided by the temperature of the water that circulates through it. As soon as it falls below the set level, the boiler turns on for heating. Therefore, if weather conditions change, you need to manually reset the indicators on the boiler. During the season, you have to resort to such manipulations more than once. This mode is inconvenient in that the boiler often starts only on short intervals time, usually for a couple of minutes every 5-10 minutes. But circulation pump systems are constantly running. Accordingly, there is a large overspending of electricity. For example, a 24 kW double-circuit boiler consumes about 60-90 W / h, that is, about 43-65 kW per month. Apart from big expense energy, there is a high depreciation of the gas boiler itself.

Attention!
The main advantage of a heating system with a room thermostat is that it turns on the boiler depending on the room temperature. A system without a thermostat turns it on when the water in it cools.

If there is a thermostat in the room, it is easier, faster and more economical to regulate the temperature in the room. The principle of operation of the room thermostat allows you to set the desired temperature parameters directly in the room and not run to reprogram the boiler every time you need to change the temperature.

Types of thermostats

There are several types of thermostats for controlling the temperature of central heating.

By connection method

The thermostat can be installed in the room or directly next to the boiler. In the latter case, we are talking about the central thermostat. The newer generation of thermostats mostly have a wireless connection to the boiler, while the old ones are connected to it by wires.

On a note!
The recommended indoor air temperature is 20 °C, at night it can be one degree higher. But in the children's room and where the elderly live or with handicapped, it is worth setting 22 ° С.

The central thermostat turns on and off the heating throughout the house, and the room thermostat allows you to change the heating mode at any time, set a special mode for weekends, day and night, or for the period of departure of the owners. If the house has one boiler with a radiator, one room thermostat is sufficient.

By functionality

By type of function, wireless thermostats for gas boilers can be divided into three main types:

• simple, which have only one function - maintaining a predetermined temperature in the room;
• programmers or programmable, which already have a number of useful features: you can exhibit the work heating system for a week, to differentiate the temperature by time of day, etc.;
• with hydrostatic function. Such devices have a built-in hydrostat that allows you to control not only the temperature regime, but also the level of humidity in the premises, as well as adjust it to the required parameters.

Attention!
Before you buy such a device, you need to calculate its required power. To do this, you need to know the total heated area and the approximate temperature level that must be maintained. So you save money by not buying a device that is too powerful, and you can also prevent breakdowns by changing the wiring in advance if it turns out that it cannot withstand such a load.

The operation of the device is as follows. It is necessary to set the desired temperature indicator on it. As soon as the air in the room cools one degree lower, a signal is sent from the thermostat to the gas boiler to turn on. The system turns on and warms up the premises. When the temperature is one degree higher than the set temperature, the thermostat sends a signal to turn off. And then both the boiler itself and the pump are turned off.

Let's take a look at what the reviews say about the operation of wireless thermostats for gas boilers. On significant energy savings and reduced boiler depreciation. Its switching on and off is reduced tenfold, and electricity is saved by turning off the pump when the boiler is idle.

Also, when weather and other conditions change, there is no need to reset the temperature on the boiler. It simply does not turn on if it is already warm, and turns on when the temperature starts to drop.

On a note!
Boilers without a thermostat show energy overruns of 25-30%. This is due to the fact that an increase in temperature over established norm even one degree leads to a large waste of fuel.

In addition to saving fuel consumption, there is a saving of electricity by about 30-40 kW per month. Not to mention less wear and tear on the equipment itself. Everything suggests that installing a wireless temperature controller for the boiler is a profitable investment.

How to properly install a thermostat for a gas heating boiler: connection diagram

It is necessary to install a room-type device in the most visited room. As a rule, this is a bedroom or living room. It is important that this is a living room, and not a kitchen, corridor or bathroom. If there are few people in the house, then the coldest room is selected.

Attention!
Before installing the thermostat, take care of the insulation of the premises. Otherwise, no savings will be obtained due to high heat losses.

When purchasing a wireless electronic thermostat for a gas boiler, we must remember that it needs a constant supply of air. Therefore, it cannot be placed behind furniture or covered with curtains. Also, it must be placed at a safe distance from electrical and heating appliances that interfere with radio waves. Danger is also touch switches and neighboring boilers that are across the wall. Also, places where the rays of the sun fall or there are drafts are not suitable, air flows from the air conditioner pass. If there are valves with thermal heads on the heating radiators in the room, it also makes no sense to install the device here.

The device is placed at a distance of one and a half meters above the floor. Given that warm air rises, and cold falls, at this distance the air has an average temperature in the room. This rule must be adhered to, even if heating is installed in the floor. The device is attached to inner wall buildings, as the outside is too cold, even if they are insulated.

The connection diagram of the thermostat to the boiler is indicated in the instructions for the device, but it is worth identifying the key installation requirements. Before starting work, always turn off the power in the house to protect yourself.

Choose a place for installation in accordance with the recommendations described above. Connect the phase and zero to it, then mount the thermostat. Now you need to connect the phase, zero and ground of the device with the corresponding contacts of the gas boiler. If the device uses standard markings, the pins are labeled N, L and PE respectively. After connecting them, the connection of the thermostat to the boiler is completed.

How to connect a thermostat to a gas boiler - see the video instruction

Advantages of using wireless thermostats for gas heating boilers

The main difference between the wireless thermostat for gas boilers is the built-in radio module, which is connected to the controller of the water heater. Accordingly, there is no need for wiring, which saves time, effort and money.

Attention!
It is desirable that the thermostat is from the same manufacturer as the boiler. This will not only facilitate installation and debugging of the device, but also ensure device compatibility. Sometimes there are problems with the latter. Moreover, this complexity is typical not only for wireless, but also for wired devices. Therefore, always consult a specialist before buying.

Wireless thermostats for gas heating boilers are sometimes available with a GSM module. Such devices can transmit text information to the phone. Boilers of South Korean and European production have built-in Wi-Fi modules that allow you to control the heating system via the Internet, adjusting the temperature in the house from a distance.

Depending on these additional features the price of the device also varies. But if you take a simple thermostat, its cost will be low. At the same time, even an inexpensive unit allows you to significantly save on electricity, fuel, and carefully use the equipment of the heating system.

For more information on setting different temperature conditions in a room using a thermostat, see the video

Given the rise in energy prices, the issue of energy conservation is extremely acute. That is why a large number of models of heating devices that consume fuel economically have been developed. However, the equipment itself is not enough. The most rational use of energy resources will help the thermostat for the heating boiler (thermostat), which allows you to control and maintain the set air temperature in the heated room.

To be able to control the energy consumption of heating equipment, it is equipped with special devices - thermostats. These devices allow you to use fuel efficiently by turning off the equipment when the set temperature level is reached. Thermoregulators are used for electric boilers, gas and, as well as convectors, heaters and other heating systems.

To achieve economical operation of the heating boiler, the thermostat turns on the equipment when the temperature drops below the set temperature and turns it off when the set value is reached. This method avoids unreasonable consumption of gas or electricity, when, for example, some of the rooms are located on sunny side and for their heating they need less heat than for other rooms.

Helpful advice! Even a slight decrease in temperature within 1 degree helps to reduce energy consumption by 4-6%.

In addition, with the help of thermostats, you can set the operating mode of the heating system, in which the temperature in the absence of people in the house or at night will be 4-5 ° C lower. Thanks to this, savings in electricity or gas consumption of about 30% can be achieved. Thus, if your heating equipment does not have such a built-in device, it would be advisable to buy a thermostat for a heating boiler. The temperature controller will provide a solution to the problem of energy overruns.

Types of thermostats for heating boilers

Equipping heating equipment with thermostats allows you to maintain a given temperature climate in the room with an accuracy of 1 to 0.5 degrees. They control the operation of the heating system using various actuators. There are electromechanical and electronic thermostats. The design of a mechanical thermostat for a heating boiler has an on / off key and a rotary button for control temperature regime.

Electronic or programmable thermostats are more advanced, but simple and straightforward to use. With their help, you can set the daily temperature cycle: in this case, the boiler will automatically switch to the specified mode. Such devices can regulate both the entire heating system and individual heating units.

There is a classification of devices into wired and with remote control. For the first importance has a connection of conductors, as well as external protection against mechanical damage. The quality of the signal supplied from the boiler to the controller, which informs about the flow of coolant into the circuit, depends on this.

The principle of operation of a mechanical thermostat for a heating boiler

In most cases, mechanical thermostats for a heating boiler are used in gas installations. This is due to the fact that manufacturers of gas boilers initially produce devices that are compatible specifically with mechanical models of thermostats. The design of a mechanical thermostat has a gas membrane, inside of which there is a special gas.

When the temperature deviates from the norm, the volume of gas inside the membrane changes and the mechanism for closing or opening the heating boiler power supply system is triggered, respectively. This is a fairly simple way to control the operation of the boiler, when its operation depends on the temperature indicator not of the coolant, but of the air in the heated room.

Using a mechanical model of a thermostat, you can set an acceptable temperature by turning a round button with divisions, which is connected to the membrane. Thus, there is an approach or removal of the walls of the membrane to the control device: this is how we set the temperature at which the connection or break of contact will occur.
