Wall-hung boiler thermostat selection techniques - brand selection Currently on the market sales of thermostat brand mainly imported brands, most of which are domestic production or domestic thermostat OEM manufacturers, a very small part of the original import . In recent years, domestic brands have gradually been recognized by users for their low price and excellent quality. In fact, the temperature controller is a very common electrical product. Its technical content is not higher than some of the computer's components (such as sound cards, routers, etc.), and it is not as high-grade as some of the radio technology content. It is because people are not familiar with, do not understand, they are mysterious. Change. At present, the technology and quality of electronic products in China have reached a considerable level, and the core components of all brand thermostats are almost the same chip manufacturers, so there is no need to pursue "imported" products, but there is no need to superstition. "The original" said. In terms of function, the programmable thermostat is nothing more than weekly programming, manual, antifreeze, and vacation functions, and there is not much room for change in the function. All programmable thermostats already have the above functions, and the only difference is the operation method. In the same function, there is no difference between comfort and energy saving.
From the price point of view, the price of imported thermostats (wireless 1500 yuan, 600 yuan cable) is twice that of imported domestic thermostats and three times that of domestic brand thermostats. The high price of imported thermostats has quality factors. More important is the import tariffs and the monopoly and misleading of domestic agents. Even if there are exemptions, the future maintenance may be a big problem. Can be described as a "luxury" thermostat, the lowest cost, I do not recommend the choice.
Foreign brands introduce their mature technologies into China, and the domestic production technology has reached the world's advanced level. With its good appearance technology and stable product quality, it is favored by users. The price is moderate, and users with higher requirements can choose.
Domestic brands have also made great progress in recent years. Some powerful and large-scale manufacturers have emerged. They are willing to invest in research and development and are willing to invest funds. No matter whether they are quality, technology or appearance, they have reached a considerable level, plus a reasonable price. It is more and more recognized by people, economical, practical, and most cost-effective. At the same time, the Chinese language interface and the operating methods that are in line with the country's habits are its advantages. It is most suitable for ordinary users who are pursuing higher cost-effectiveness.
Before visiting the fireplace, we must have seen the central air conditioning and temperature controllers in the buildings, halls, and offices of hotels and office buildings. We have noticed that many of them are domestic brands. In fact, he and the wall-hung boiler thermostat are one thing. Almost the same (for myself, a slight change can be used in a fireplace), but the software is slightly different.
Wall-hung boiler thermostat selection techniques - according to the function of choice Wall-warming heating thermostats are mainly: mechanical, electronic, electronic and non-programming and programmable two.
Mechanically known as "large knob" (but the knob type is not necessarily a mechanical thermostat), the use of inflatable membrane box as a thermal element, the structure is relatively simple, short life, control accuracy is also relatively low, low-cost, low-cost, not recommended for families use.
Electronic non-programmable type thermistor (NTC) is used as a temperature sensing element, LCD display, long life, high control accuracy, but can not be divided into periods of control, but has the advantages of simple operation and intuitive, suitable for home use often at home ,Especially suitable for the elderly (programmable thermostat operation is a bit difficult for the elderly, if improper operation will be counterproductive), because there is no need to time control, can maintain a relatively stable temperature throughout the day, according to need at any time Adjustment.
Electronic programmable type is a kind of thermostat that is commonly used nowadays. Thermistor (NTC) is used as a temperature sensing element and liquid crystal display can realize automatic control in different periods. According to the living habits and schedules, the day can be divided into several periods. Each period is set to different temperatures. Get up at 6:30, go to work at 7:30, go home at 18:30, and sleep at 22:30. This can be set as follows: 6:00-7:00, higher temperature (20 degrees), very comfortable to get up; 7:00-18:00, lower temperature (15 degrees), no one at home, saving energy; 18: 00—22:00, higher temperature (20 degrees), you can feel warm when you come home; 22:00—6:00, set a lower temperature (18 degrees), people are not sensitive to temperature after falling asleep and winter quilt Thicker, lower temperatures do not affect comfort while saving energy. Programmable thermostats are suitable for most homes, and are not recommended for elderly people, as improper operation can be counterproductive.
Wall-hung boiler thermostat selection techniques - wired, wireless and power supply mode selection The thermostat has a wireless and wired control of the wall-hung boiler, the power supply mode is divided into battery-powered and 220V power supply.
Wireless and wired thermostats, preferably wired thermostats, are cheap and reliable, but the control line between the boiler and the thermostat should be reserved during the renovation. If there is no reserved line and the conditions for the open line are not available To consider the use of wireless thermostat, wireless thermostat sub-fire (thermostat) and receive two parts, the transmitter part can be placed in any room at random, and the receiver is installed near the boiler, wireless thermostat although high prices, However, there are also rooms where people can be placed at any time, such as in the bedroom where the temperature can easily rise at night, without having to consider the living room where the temperature is relatively difficult to rise.
In terms of power supply, the most common early stage was battery-powered, usually two batteries of No. 5 or No. 7, which can be used for more than one year. They can be mounted directly on the wall surface and do not require a cassette. At present, the temperature controller of 220V power supply is also gradually increasing. Because it is installed in a standard 86 cassette, it has the characteristics of thin, protruding walls, and beautiful appearance. In addition, due to the operation of the backlight (battery-powered thermostat due to the power supply Limits are not backlit), very convenient at night or when the light is not good, if you feel unsafe can also be used to change the temperature of the 12-volt power supply controller, if the conditions (to provide 220V power supply) is also a good choice. There is no current communication between the thermostat and the wall-hung boiler, which is only equivalent to a switch for the furnace, so no matter if the battery or the 220 power supply is not a problem.
Wall-hung boiler thermostat selection techniques
All European and American brands and domestic brand boilers on the market, including some Japanese and Korean brand boilers, are equipped with standard and universal thermostat interfaces, and most of the current temperature controllers on the market are designed for this type of interface. Therefore, there is nothing special about a certain brand of boilers (especially those recommended by the boiler installation company, the so-called dedicated thermostats are not manufactured by the boiler manufacturers themselves or specially produced for the branded boilers, and they are all dedicated thermostats. The universal thermostat manufactured by the manufacturer can be said to be universal.
