The thermostat is a device for monitoring the temperature of air or water that enters the device. When the temperature value specified in the theroregulator is achieved, it turns off the heating device. Subsequent inclusion occurs after the temperature has decreased. Some heating devices are equipped with temperature regulators or built -in relays, but for those whose configuration does not include such an addition, it is acquired separately.

What is a thermostat for
Heating systems that are not equipped with thermostats are not convenient for use. They must be periodically turned off, independently focusing on the level of warming up of housing. The temperature regulator performs this work automatically and makes it possible to heat the home or industrial premises in advance.
Thermostats lower the fire hazard of heating equipment. The heater with a thermostat works for a long time and does not overheat, thanks to the temperature sensor that regulates the heating level. From here comes another plus of using thermostats - electricity savings. Use thermal controllers and aquarium owners. Using these devices, the optimum temperature in the abode of fish is maintained.
The thermostat is functioning is quite simple - the optimum temperature for the air or aquatic medium is set, the relay in the thermostat is triggered when the indicated value is reached and the heating device turns off. This is very convenient for any types of premises - warehouses, residential buildings, administrative buildings, etc.
Thermostats work not only for heat, but also for cold. An example of this is the equipment of refrigerators that disables the engine when it reaches a given temperature in the chamber. All heat controllers are divided into three main groups:
- electronic;
- electromechanical;
- mechanical.
Electronic thermostats
Electric thermoregulators have one main advantage - a high indicator of determining and adjusting the heating of housing. They are easily adjusted and controlled by heaters connected to them. The thermostat of this type is from:
- determining heating of the air sensor;
- microprocessor processing and transmitting a signal;
- details of control of control, which in this case plays the role of a thermorele.
Electronic thermostats are used to equip the general heating system of an industrial building and private housing, adjust the functioning of air conditioners and climate control. Thermoregulators of this design are often included in the complete set of the Smart House system, in it they monitor not only the air heating in the house, but also the number of degrees in the devices included in the system. This is necessary to reduce the probability of fire formation.
Electromechanical thermoregulators
Electromechanical thermoregulators in design are the simplest. The heart of this device is a relay, it carries out the shutdown and connection of devices. Devices of this type are installed in irons, electric stoves, curves and other devices for everyday life that change the temperature of their surface or internal elements.
The relay design in these devices is a contact group and a double plate of metal. When heated, the plate changes its position and opens the contacts, this stops the current course to the plate and spiral. When cooling, the plate comes to its original position and closes the contacts. This cycle holds the temperature at the required level.
There is another popular variety of mechanical thermostats, they have a slightly different design and principle of action. The relay in these devices expands when exposed to high temperature. This thermostat is installed in heating tanks, oil heater. The relay in this type of design has the shape of a cylinder, filled with a sensitive to the increase and lowering of the temperature with a substance. With an increase in temperature, this substance expands and opens the contacts. There is a special and complex chain drive. When cooling, the substance returns to the original volume and the contacts are closed.
Thermostats
The Termostat regulator is another group of thermostats widely used in the appliances for life. One of the popular applications of this type is heating systems. Outwardly, the thermostat is similar to a locking crane. Such a device helps to maintain the necessary temperature level in residential, administrative and office premises. Automobile engines are also equipped with these devices. It is not recommended to use the thermostat for flexible temperature programming, since they have the main modes of functioning, going beyond which the system loses tightness and fails.
The design of the thermostat is a thermal cylinder with a rod, which is filled with a substance sensitive to fever. When heating the substance to a certain mark, it increases in volume, the rod extends out and blocks the movement of water in the pipes.
Mechanical thermoregulators for infrared heaters
Infrared heaters are very popular in household and industrial use. The principle of their work is the heating of objects located in the zone of radiation. These devices, like other heaters, are equipped with thermostats, but a slightly different design. The first large category of thermal controllers for infrared heaters is mechanical.
Mechanical thermoregulators for infrared heaters are presented on the market by most brands that produce this type of product. Each brand has some structural features and differences, but in general, according to the principle of operation, all mechanical thermostats are similar to each other. In most cases, the installation of such regulators is carried out on the wall - are applied or crashed into it. Thanks to this, a combination of a thermostat with wiring of any type is possible.
The range of temperatures supported by the temperature thermoregulator - from +5 to +30 C. The dimensions of the device are small - size with an ordinary standard household outlet. This allows you to harmoniously enter the equipment into the interior. The regulator has a pen for determining the temperature level to which the heater heats the system. There is also a button for disconnecting or turning on the thermostat itself.
Programmable thermal controllers for infrared heaters
A programmable or digital thermostat for infrared heaters makes it possible to achieve maximum comfort in the house. This is the most perfect type of equipment, convenient in operation and practical. The range of installation temperatures is wider than in mechanical devices and is 5-45 C. This allows us to significantly increase the scope of equipment and the level of comfort he created.
The main difference between programmable equipment is the ability to set a complex heating program that will function for several days or weeks. At the same time, the program makes it possible to set a different sequence of change of temperature and control over it for every day. Such a thermostat is equipped with two sensors, the purpose of the first is to monitor the heating of the premises as a whole, the second - the heating of the heater itself. Programmable devices are used for the equipment of the Smart House systems.
When choosing which thermostat to buy, you need to consider the following factors:
- external climate conditions;
- the quality of thermal insulation of the heated structure;
- the number of heaters in the system;
- type of used devices for heating.
The regulators intended for infrared heaters are able to maintain the operation of several heaters, but their total capacity should not exceed 3-3.5 kW. For circuits exceeding this value, a built -in magnetic starter is used, which redistributes the load on different devices of the network.
Review of manufacturers of thermostats

-
- the RT500 model and its wireless version of the RT500RF have 5 programs for daily work that the user sets. The RT300 and RT300RF models support one temperature level set by the user. All models are equipped with a LCD display and backlight.
When choosing a thermostat for private purposes, two basic rules should be observed:
- select products that meets the requests;
- pay attention to the price.
A good temperature controller will not cost less than 15-20 EUR. Cheaper products increase the risk of a fake made of low -quality materials. As a result, losses will be calculated not only at the cost of the thermostat itself, but also with the equipment connected to it, if it breaks as a result of overheating.
