ThermoRegulators: types, purpose and principle of operation

An electric thermostat is a device that allows you to maintain a certain temperature level in any heating system. It will turn off the heating element when the ambient temperature reaches the set value and will automatically turn on again when it drops below the limit level. Such work does not require the involvement of personnel, therefore it allows you to autonomously maintain the optimal temperature at any facility.

It is practiced to classify regulators simultaneously according to several criteria:

for its intended purpose (temperature regulator for an incubator, for controlling the temperature in a room, heating boiler);
by operating temperature range;
by type of working substance (thermostat with air, liquid, solid temperature sensor);
by functionality (availability of programming, remote control, etc. matters),
according to the principle of operation and design (it can be an electronic, mechanical or electromechanical thermostat).

The price of a thermostat depends on the factors described above, as well as depending on the purpose for which you want to use it.

Operating principle of thermostats

The device is installed in an area that is not exposed to the direct heating effect of devices (in this case, it can be a thermostat with a remote sensor or an element of a built-in structure). In this way, the device can obtain information about the temperature level in the area where the sensor is located and, based on this information, control the operation of heating elements or heating devices.

Main types of thermostats and thermostats

Mechanical devices - uh These are the simplest and most affordable devices, which are especially often used when working in a small room. They are not susceptible to power surges or electronic failures, therefore they are reliable and easy to use. At their price, mechanical thermostats are the most affordable of all.
Electric thermostat - Such devices are often used to complete household electric stoves and electric kettles. Depending on the principle of operation, you can buy devices whose operation is based on the use of a working membrane (bimetallic plate) or a capillary tube.
Electronic thermostat with temperature sensor - Such devices are used most often today: they are accurate, reliable, and convenient. Their work is based on the fact that a temperature sensor, which is installed in an area without intense heating or draft, constantly transmits information about the temperature of the environment to the controller. The latter processes the data and supplies a control signal to the heating devices.

Unfortunately, I got the wrong product. I ordered a less functional device than I wanted. WILLHI WH7016C - this thermostat can only work in one direction - either cooling (when the threshold is exceeded, it turns on the cooler) or heating (when it falls below the threshold, it turns on the heating). For some tasks this is enough. An incubator, for example. But aquarists will probably prefer a different device. More precisely.

First I ordered, and then I found it. But, again, the prices. In our outback, finding something resembling a thermostat is simply unrealistic. There are some electromechanical ones like irons, there are some for refrigerators as a spare part, there are Chinese household ones for heated floors, there are for electric kettles. But in reality, everything is tailored for a specific application. And there is simply no range around room temperature. You can’t put a thermostat from a kettle on an incubator. :)

In principle, everything is quite correct. Industrial design, quite neat. Install on the front panel of anything with a thickness of at least 5 mm. Otherwise, you will have to pile up gaskets or invent your own fasteners. The video shows that it was not possible to press the tip of a thin screwdriver.

The power part is on the horizontal part of the board, the microcontroller is on the vertical part, behind the back of the indicator. What’s funny is that the Chinese even marked the chip as WH7016C. They hid the brand of the microcontroller and averted their eyes with strange markings.

Scattered device.

Inside.

Settings are made according to the manual from the muzzle. Four buttons, an indicator with numbers and two LEDs. Seems simple enough.
There are two modes for thermoinertial applications - setting the temperature hysteresis and setting the time delay for turning on the relay. But here you need to think. Because there is no longer an immediate reaction to installations. In general, using hysteresis, this thing can maintain temperature with a minimum accuracy of ±2 degrees. The accuracy is not enough for an aquarium, KMK. The time delay can be set to zero. If everything is set rigidly, then the relay makes a “clack” immediately. The relay activation indication is displayed on the upper left LED on the device’s face. The bottom LED seems to only serve as a setup mode indicator.

Pros:
Works!
Made neatly, looks good, glows quite brightly.
Remembers settings and resets to default.
Has temperature sensor calibration.
With a manual it can be configured.
Compact.
Easy to install.
Our standard voltage is 220V (there is a constant 12V version).

Minuses:
There is no Russian manual.
Even with the manual, the time delays and hysteresis make me think twice.
Doesn't shine with accuracy in maintaining temperature.
It can only turn on and off one of the options - heating or cooling.

PS
A couple of photos from the review were borrowed from the website of a Russian-language store. I'm sorry.

I'm planning to buy +34 Add to favorites I liked the review +29 +50

People's mood, well-being and performance depend on the air temperature in the surrounding space. Its meaning, comfortable for each person, is very individual. While some people work well at +18°C, others need at least +23°C.

In such cases, it is convenient to install a thermostat in a socket for household heaters to set the desired temperature. The device independently reads the room temperature and controls the operation of the heater.

Agree, this is very convenient - you don’t have to constantly be distracted by turning the heater on and off. All that remains is to select the optimal thermostat and install it. We'll show you how to do it.

To understand the variety of offers, you need to find out the operating features of different thermostats, take into account the parameters that determine the practicality of the device itself and the comfortable operation of the heater. Installing the thermostat is quite simple, the main thing is to adhere to the installation rules indicated in the article.

When you are in the office, you want nothing to distract you, and all thoughts to be focused only on the work process. Optimal temperature conditions in the room help achieve this goal.

It’s good if you don’t need to bring a warm jumper with you in the cold season to warm up slightly, run to the heater or air conditioner, setting and changing the settings. A thermostat will help regulate the temperature in the room.
