In recent years, many of our compatriots have acquired country houses and cottages for permanent residence, and equip them with autonomous water heating systems. It goes without saying that all the owners of such "houses in villages" are interested in ensuring that a comfortable air temperature is always maintained during the cold season, that is, so that it is not very hot or cool at times. This means that the boiler must be properly controlled by switching it on or off at certain times.
This is the role played by digital thermostats , which are also called room thermostats or sensors room temperature. With the help of these devices, you can not only easily and easily provide a comfortable air temperature in your country residence in winter (and it will be maintained in automatic mode), but also save good money on fuel. Let's try to figure out how this device works and how the savings are achieved.
To begin with, it should be noted that almost every heating boiler has its own built-in, "internal" thermostat, which monitors that the water temperature is within certain limits. Since the water in the autonomous heating system cools down rather quickly, this device works often. The air changes its temperature slowly, and therefore, in fact, there is no need for such frequent switching on and off. To optimize the operation of autonomous water heating systems, electronic thermostats are connected to them, which control the system depending on changes in air temperature, not water.
These devices are now produced by many manufacturers and are relatively inexpensive: in any case, the savings from their use, as a rule, are many times higher than the cost of purchasing them. They are quite compact, and in many cases their installation will not be difficult. This can be done without the help of specialists, since the instruments are supplied with detailed installation instructions. You can place them in any convenient place, since the connection is carried out using an electric cable.
Using electronic thermostats is very simple: they just need to set the required air temperature in the room. As soon as it goes beyond user-defined limits, the boiler will either turn on or off (according to the relay principle). By the way, the same procedures will be carried out with the circulation pump, which, in the case of control by means of a built-in thermostat, works constantly.
