Thermostat for infrared heating: connection diagram, see vibir
One of the advantages of scorching systems, which victorious electric energy, is the ability to control their robot both in manual and in automatic mode. Infrared heating systems did not become a culprit, because, due to their inertia, they require efficient and high-current devices to regulate the temperature and heat in the premises.
Vikoristannya in the design of thermostats in modern technology allows only aaaaaaan to achieve the necessary accuracy, and the speed of energy generation. Before that, innovative devices can be connected to the “smart house” system, relying more on automatic optimization of robots and infrared heaters.
See thermostats
Depending on the design features of the thermostat for infrared heating, it can be divided into two types: electromechanical and electronic.
Electromechanical thermostats
A mechanical thermostat can be the simplest attachment - a toggle switch on and a temperature control button
Lance switching in an electromechanical thermostat is driven by a special bimetal plate, cut off by the method of combining two smugs from metals with different thermal expansion coefficients. When heated, one smuga will move more strongly for another, so the plate bends, roaring the electric lance. When the supply voltage is applied, the heating is turned on, and the temperature changes again. Cooling down, the bimetal element rotates at the outer position, the contacts of the heater increase, flickering. The process is repeatedly repeated, and the temperature is set to be repeated at its own pace.
On the case of electromechanical thermostats there can be a control knob, a scale, additional functional buttons and indication elements.
Electronic devices
Modern temperature controllers are not required, the principle of any kind is grounded on the mechanical contact. The design of the electronic thermostat consists of several elements:
- temperature sensor, which changes its parameters
heating stage;
Electronic regulators can be equipped with microprocessor control systems, which allow you to program the appli- cation of the singing algorithm in a fallow time, tomorrow morning. Such attachments can be integrated into the “smart booth” system to control the operation of the scorching device.
Temperature sensors
Regardless of whether the temperature sensor is used or is used for a wine installation, you can use either a thermistor or a thermocouple. The first element at coliving temperatures changes the internal opir. The other is to revenge the soldering of two metals with different potentials. It vibrates the electric stream, the value of which is directly proportional to the heating force. Knowing the staleness of changing the parameters of the temperature sensor, it is not easy to put together the algorithm of the microprocessor robot.
Sensors of another type (thermocouple) are superior and provide accurate readings at the boundaries of 0.1-0.5ºС.
The remaining rocks of the great breadth were filled with thermal sensors, which transmit their parameters through a radio channel. The advantage is the possibility of installation in any place without the need to lay darts, which is especially important, as it is necessary to switch the stele heater. To live like this, attach it to batteries, like, protecting the minimum strum of life in the barn mode, change it no more often than 1-2 times per river.
Pіdbіr thermostat
When choosing a thermostat for infrared heating, it is necessary to focus on the functionality and efficiency of heating. But the main parameter, which is the designation of the building, the installation of the installation, is the first step of the project.
When the parameter is moved, the switching element of any thermostat (chi electromechanical or solid-state relay) will inevitably go out of tune.
Razrahuvati strum navantazhennya is awkward. We need to calculate the amount of fire protection before us. For which it is sufficient to divide the indication of the attachment W (watt) to the connection voltage V (volt). Shukana value will be represented by A (amps).
For example, for an infra-heater with a heat output of 2.2 kW, the storage space is 10 A (2.2 kW = 2200W, and 2200 W / 220 V = 10 A). Having added 15 - 20% to the reserve to this parameter, it is necessary to take a stream of thermostatic pressure, which will increase 12 A. The value itself needs to be oriented when adding control.
Quite often, in the technical passport for the selection of pickers, they indicate the maximum tension that should be communicated. Tse i є the value of that desire, as it is possible to connect to the thermostat without a fight.
As a rule, it is attached, recognized for work in combination with infrared heaters, covered for connection to a number of outbuildings, however, if the sum of the connection intensity is more than 3 - 3.5 kW, it is not recommended. If necessary, commutation of the voltage is greater than the qiu value of the connection circuit is responsible for the additional contactor or the magnetic starter.
Features of connection and installation
Stellas or wall-mounted infrared heaters with a thermostat, obviously, can work normally, however, if the thermostats are not very corrosive - their sensors do not work on the actual temperature in the application, but on the stage of heating the body of the scorching tool. The axis of this is the correct installation scheme for transferring the wine to the distribution of control elements.
In this case, the installation of the thermostat is obov'yazkovo guilty of zoning the robotic infrared heater, otherwise the robot will be built incorrectly. When the temperature controller is installed, follow simple rules:
- as well as installing a stellar heater, the thermostat is more likely to be roztashovuvati on the outer wall. Really vikonannya ІCh-opalyuvacha vmagaє placement of the regulator on the same surface, with the necessary remoteness;
- the optimal height for the logs is about 1.5 meters;
- installation without intermediary laying in the type of fastening - in the case of a wall, it will be required to install wall grommets, and accessories for surface mounting will require the installation of mounting boxes for the cable and the wire of the thermal sensor;
- as the scheme of installation of transferring the attachment to the outer wall of the booth, thermal insulation is installed under the first building. Tse dopomozhe niknuti pomilkovykh spratsovuvan relay;
- The selected place for the installation of the temperature controller can be found on the windows, doors and scorching accessories.
The scheme for connecting the IF-heating through the temperature controller does not allow for a suitable underwater stone, so the installation is the same as installing an electric socket. The natural advantage is the resistance of the cutting of the mounting rods to the tension of the heating.
The temperature regulator can be two pairs of terminals, which are connected to the automatic switchboard from one side and to the ІЧ-heating from the other side. As a scheme for transferring the connection of a number of scorching accessories, the stench is due to be switched on in parallel. If possible, two options for inclusion:
I guessed, in another way the cable can be stretched more.
During installation, it is important not to confuse the inclusion of zero and phase conductors, the shards of other models of electronic regulators are sensitive to this kind of "reverse polarity".
Scheme for switching on the push-pull switch on the transfer of the installation of a magnetic starter and contactor. At this time, the temperature controller's terminals are connected to the power relay, and the heaters are connected through the starter's operating contacts.
With the connection of infrared possession, the next step is to add respect to the ground. The yogo circuit is to blame for the overhead, and the grounding busbars may be a low internal support. When working with hard troubles, we will not take over and install an outbuilding of a sluice switch.
Nasamkinets varto indicate that you can choose the required thermostat on the basis of theoretical indicators, looking around that port. And then I installed that connection to an infra-red heating vimagatime for you, not theory, but proof of that practical experience. For the least sumnivіv go to a professional electrician. Remember - with electricity, it’s better not to get scorched by electricity!
As an addendum, we recommend that you familiarize yourself with the amateur video instructions for laying infrared wiring, including the installation of a thermostat and a temperature sensor in detail:
