How many times have they told the world that arrogance in the conduct of electrical work may be of no use. And if you decided to connect the thermostat for the "warm floor", look through the "Electrotechnical Handbook" for starters. Boring and incomprehensible? Then immediately find the phone of a specialized company!

Types and ways of mounting the temperature regulators
The main element, without which the "warm floor" is simply unthinkable, is the thermostat. The thermoregulator is an electronic device, thanks to which the temperature regime of the heating system is controlled.
Therefore, the question: "What is a regulator needed for" should not arise. It is the thermostat for electric underfloor heating that allows you to reach a comfortable temperature without participation in the process of human control.
Types of temperature regulators
It is necessary to distinguish the following types of temperature regulators:
• by type of control
• according to the installation method
• by the number of controlled premises.
The control type of the thermostat can be non-programmable and programmable. The non-programmable (analog) thermostat maintains the necessary temperature regime by mechanical rotation of the handle.
The device has a minimum set: indicators of switching on and off of heating elements and a scale on which the system's working capacity is displayed visually. An analogous principle of control is electronic-mechanical thermostats.
Thermoregulator programmable for the warm floor represents a more complex system equipped with:
• Display
• Keyboard
• a time timer.
The owner of the programmable thermostat has the ability to program the system parameters, including the temperature regime, as well as the heating or cooling rate of the system. The programmable thermostat allows you to save energy significantly, especially in the hours when there is no one at home and the system is simply in a "sleeping" mode. For example, the thermoregulator for the warm floor of legrand has numerous options that allow you to set the programming mode for several days, while displaying the process of executing the program on the display.
The maximum accuracy of the programmable adjustment gives the chance of carefree time for the owner of the warm floor with a programmable thermostat.
Ways of installation
The method of mounting the thermostat allows to integrate it into a standard mounting box with the type of clamping of wires under the screw, or to attach the thermostat directly to the surface of the walls. This method is an ideal variant of the connection scheme for a floor heating controller for wooden houses and cottages.
electric underfloor heating
By the number of rooms controlled by the thermoregulator, it is possible to install a single-channel system that monitors the heating of a single room, as well as a multi-channel system capable of monitoring two or three rooms.
For example, the thermostat for the devi electromechanical floor is designed for connection of all types of heating cables: DEVI, Nexans, and heating mats - Millimat, DTIR-150. The thermostat is equipped with a wire temperature sensor and a LED indicator.
system of water "warm floor"
For systems of electric and water "warm floor" the operation of the thermostat differs strikingly. In the system of electric "warm floor" the thermostat acts on the heating system in an active way, regulating the voltage. Thermostats for the water-heated floor system are a kind of a link between the servo in the distribution manifold and the tap, which circulates the heated water.
The thermostat for water-heated floors commands the servo drive responsible for the water circulation in the heating circuit. The thermoregulator mission ends here. Therefore, the reaction to the commands of thermostats in different systems is different. The reaction of the thermostat in the electrical system is instantaneous, as a result - the temperature of the system changes. The reaction of the water thermostat has a time reserve calculated to fill the system with the required volume of the heated coolant.
The design of thermostats for the system of water "warm floor" is similar to the design of electric temperature controllers.
The choice and connection of the thermostat depends on many significant factors and depends on the specific technical solution for the arrangement of warm floors. Therefore, provide the functions of connecting the thermostat to a specialized company.
How to connect a floor heating controller
The connection of the thermostat is carried out at the stage of installation of the system.
Connection to the network can be made directly from the electrical panel and through an ordinary outlet. In case of direct connection, an automatic switch must be provided to protect the thermostat.
When connecting the thermostat via a socket, it is necessary to take into account the load of electrical appliances that are powered from this outlet. The type of wiring for connecting the thermostat is provided open or hidden.
The desire to connect the thermostat and the system is commendable, however it is recommended to entrust this work to specialists. The installation specialists excellently understand the general scheme of connection of the thermostat and will perform installation, installation and connection in the shortest possible time. Recall that the thermostat will monitor the temperature if there is an installed temperature sensor.
The connection diagram of the thermostat from the manufacturer is shown on the housing. Regardless of the type of control, any model has a distribution block for connecting electrical wires. This is a seven-pin connector with the following contact functions:
• 1 pin is for connecting the phase from the socket or the switchboard
• 2 pins connect the zero cable
• 3 contact is for connecting a cable that leads directly to the warm floor
• 4 contact is for connecting the warm floor phase
• 5-contact - backup
• 6 and 7 pins are for trunking the sensor wires.
It does not hurt to remember that the wires for installing the thermostat are different in color: the white, black or brown wire is L (phase), the blue wire is N (zero), the yellow or green wire is ground.
The connection sequence for the thermostat is as follows:
• connection to the sockets 1 and 2 of the mains lead, rated 220 V. To the terminal 1 connect the L phase, to the contact 2 - N zero.
• connection of the heating cable of the floor: N zero is applied to the third contact, the L phase wire is connected to the 4-contact.
• Connection of the built-in temperature sensor of the floor is carried out to 6 and 7 without observing the principle of polarity.
The connection of the heating cable floor and the thermostat is shown here.
