The most crucial moment in installing a heated floor is connecting heated floors to the thermostat. This electrical appliance maintains constant comfortable temperature in a residential area, consuming a minimum amount of electricity.
The thermostat is designed to stabilize temperature indicators, auto-connect and disconnect heating devices. The electrical appliance takes readings from the temperature sensor and automatically turns off the electrical power when it reaches required temperature. Even at this time, the appliance is active and continues to automatically regulate the temperature. When the temperature drops, the regulator resumes its activity.
Thermostats of different heating mechanisms have different automatic control mechanisms.
For water floors:
The peculiarity of its operation is the physical limitation of the inlet of boiling water into the heating mechanism. This ensures the required volume of water at the desired temperature.
Types of thermostats:
Depending on the number of control channels, the thermostat is:
By mounting method:
At the moment, many varieties of heated floors with heating elements are produced, the most common among them are:
The thermostat is mounted in the wall near an outlet or switch. A mounting box for the thermostat is installed in the prepared funnel in the wall, to which the electrical wires (zero and phase) of the power supply and temperature sensor are connected. Next, the thermostat is connected.
The thermostat mechanism has side sockets to which the electrical wiring (220 V) is connected, temperature sensor and a heating element.
Knowledge of wire colors is important:
Connection diagram:
Connection diagrams are different and may differ, so manufacturers number all electrical contacts for correct connection.
Instructions for connecting a warm water floor:
In this case, the thermostat controls the temperature of the air, and not the heating of the coating.
Connecting the thermostat to a two-wire cable. The two-core cable system under the protective layer consists of two current-carrying wires. It is easy to install because the connection is made using a single wire, as opposed to a single-core electrical cable.
The connection diagram shows that in a two-core electrical cable 3 electrical wires are in contact: brown and blue are current-carrying, yellow-green is grounding. The phase is connected to connector 3, electrical contact 4 is connected to zero (blue), and contact 5 is grounded (green).
Connecting a single-core cable. The design of a single-core cable consists of one current-carrying electrical wire (white). The second green wire is intended for grounding the PE shield. Wires are connected to the thermostat electrical contacts No. 3 and No. 4 white, and the green one is connected to No. 5.
Connecting warm mats is almost no different from the process for cable heating.
Let's just look at the differences:
To properly connect the thermostat to warm floor do it yourself, you need to strictly follow the recommendations installation work:
After all installation work, it is necessary to test the systems for operation. Areas with uneven heating are disconnected from the network and tested for resistance. Detected problems are eliminated and the functioning of the heated floor system is restored. Right installed system determined when obtaining the required climate at several stages of turning on/off the heating elements.
Controlling and setting the electric floor heating thermostat is as follows:
The most common way to connect a water heating mechanism is using a manifold. The ends of two pipes are connected to the mechanism: one to the supply comb, the second to the return comb. Each circuit receives a coolant of identical temperature. This method not very practical, because you need to determine the air temperature based on your own feelings.
To simplify work, flow meters are installed at the inlet to help straighten temperature norm. In this case, control is also performed manually. Thermostats are designed to automatically control the device, and servos play the role of an executor.
For large plot heating and an extensive heating network, it is better to install thermostats with servo drives. Servo drives are located in each perimeter on the automatic coolant supply comb. The role of the servo drive is to automatically submit an order to reduce and add the volume of coolant. Thermostats are placed in each individual room where this type of heating is available. They are interconnected with servos, which receive special control signals.
The controllers check both the floor temperature and the climate temperature and are also equipped with a programming function. It is necessary to control and regulate the temperature if such a floor is used as the main source of heating. Models are made that track 2 coefficients at a time. In this case, the primary information is data on the state of the airspace, and the floor temperature is represented by a secondary indicator.
The heated floor regulator functions as follows: the desired temperature can be programmed on the mechanism panel. If there is a discrepancy even by 1 degree in any direction, a signal is sent to the servomotors, according to which the flow of coolant increases or decreases. Some time later, the temperature situation returns to a normal state.
Automated control of temperature indicators greatly simplifies the control of water structures. Adjust the comb and mechanical valves manually to in this case there is no need.
Installation of a warm water floor temperature sensor. Electrical sensors are mainly located inside the thermostat.
Instructions for installing the thermostat:
Temperature meters are mainly external. This electrical mechanism is attached to the edge of a long cable. This electrical appliance must be installed in the floor, the required gap between the wall and the device is at least 50 cm. It is located at the same distance from nearby pipes with coolant. The other end is brought to the regulator and connected to the corresponding electrical terminals.
The installation of the thermal device must be carried out before pouring the screed. For further replacement, it must be placed in a corrugated sleeve. The edge of the corrugated sleeve, which is located in the screed, must be insulated. The other edge fits into the groove on the wall and rests on the thermostat box. This installation is quite labor-intensive, but it allows you to easily replace a faulty sensor.
Among the most popular companies specializing in products of this kind are the following:
Electric installation work must be carried out in accordance with safety regulations. If these rules are neglected, there is a high risk of adverse consequences.

Underfloor heating systems in Lately have become quite common. They not only increase comfort, but also serve as a good addition to the main heating system. For efficient but economical operation of the heated floor, it is necessary to install a thermostat that turns the system on or off. You can see what it looks like in the photo.
Connecting a thermostat to a heated (water) floor is not necessary, although its use contributes to more economical coolant consumption. As for electrical and infrared systems, the installation of a thermostat is essential for their operation.
Before choosing the place where the thermostat will be located. There must be a 220 V electrical network next to it. Between the electrical network and the thermostat, it is necessary to leave space for the location of the circuit breaker.
When creating an electric heated floor, you need to provide space for a temperature sensor. It is usually placed near the thermostat. It is unacceptable to cover it with furniture.
In the case when it is used to heat the floor electrical cable, which is laid in the thickness of the screed, then the temperature sensor is removed from the concrete, placing it together with the inside of the corrugated pipe. As a result, one end of the pipe is located in the thickness of the screed, and the other is brought out to the wall so that, if necessary, the faulty sensor can be removed and replaced without removing the floor covering.
After completing the installation of the electrical system, markings are applied at the place where the thermostat will be installed. The connection diagram for the heated floor controller will help with this. If the device is built-in, then a niche is made at its future location (read also: " "). To install the overhead device, use self-tapping screws and dowels.
Please ensure that the power of the heating element of the underfloor heating system and the thermostat are compatible with each other. The load on the heating element must be less than the maximum power of the thermostat.
When installing a water heated floor, the temperature sensor is fixed at a height of about 100 centimeters; it can be placed next to the thermostat. But we must take into account that there should be no additional heating sources near the sensor.
After the underfloor heating system has been started, you need to place a regular thermometer next to the temperature sensor and set the required heating temperature on the regulator. The underfloor heating system should maintain stable performance for several hours. After testing the heated floor for normal performance, you can use them. The thermostat makes it possible to set the required temperature and thereby save on coolant.
There is nothing complicated about how to connect a floor heating regulator. But you need to follow the instructions exactly and follow the scheme for performing this work. In addition, the connection must be made with the electricity turned off - this is required by safety regulations. As a result of installing a heated floor system, within a few hours you will notice how much more comfortable the house has become.
In underfloor heating control systems, the role of the control unit is played by a thermostat - a device that processes information received from a temperature sensor and, in accordance with a given mode, turns the floor heating on or off.
With an electric floor heating system, thermostats are required to be installed. Installing a thermostat in a water heated floor system is not necessary. But, if the floor is an additional heating measure, and the temperature of the coolant at the entrance to the circuit is above 50 degrees, installing a thermostat will solve the problem of room overheating.
Thermostats for any underfloor heating system can be:
Changing modes on non-programmable thermostats is done manually, using a rotary control (mechanical adjustment) or buttons (electronic digital).
Programmable thermostats are more expensive and more difficult to control, but they can save significant energy resources by turning off floor heating or lowering its temperature at night or during the day when heating is not needed.
Mechanical non-programmable thermostats are controlled by simply turning the knob to the specified level. Electronic digital - using buttons, touch panel or remote control. The price of non-programmable thermostats is lower due to the extremely simple logical part.
According to the installation method, thermostats are:
The choice of installation type is a matter of taste, but it does not affect functionality.
The sensors are a thermocouple made of two wires that changes the resistance of the circuit when heated. The wires are connected to the corresponding terminals of the thermostat. Sensors are:
Remote sensors are divided into floor or air temperature sensors. The first ones are installed simultaneously with the installation of heating elements directly under finishing coat, the second - in a place convenient for measuring air temperature. Built-in sensors are located right inside the thermostat. Some thermostat models have both types of sensors.
In the bathroom and kitchen it is better to install thermostats with a floor temperature sensor - the air in these rooms can be heated by the stove or hot water, the floor will remain cold.
Electric heated floors are made using a high-resistance heating cable or infrared film. They are laid on a specially prepared base, after which the floor is screeded and the finishing coating is laid.
Thermostat connection technology:
Thermostats for water floor heating systems are a device for controlling a servo drive that regulates the flow of coolant into the heating circuit. They can be either electronically or manually controlled, while such control systems usually use sensors for measuring air temperature rather than floor temperature, due to the high inertia of heating.
All work on connecting electrical circuits must be carried out when the circuit breaker– this is the key to your safety!
Today, “warm” floors are becoming increasingly widespread as an alternative to traditional convection additional heating of rooms. And if in country houses the most popular cable systems, then the owners of city apartments prefer to use film, infrared coatings.
However, to automate and increase energy efficiency of work, operation of any electrical systems warm floor is impractical. Available today various systems control the temperature regime of the heated floor, which you can simply connect yourself.
To connect, you will need a minimum of tools that are usually used when performing electrical work:
The sequence of installation and connection of the thermostatic device is as follows:
The advantage and comfort of using heated floors is unlikely to be fully experienced if the installation and connection of the temperature control device is carried out incorrectly or with defects. In this case, trial activation and verification are a very important step.
They are carried out under the control of the home owner, who must be sure that the electric floor heating system can subsequently be left unattended.
The check and test run sequence is as follows:
Device and connection diagram When using a thermostat to control a heated floor system, it controls the temperature and acts as a switch for the servo that controls the hot water supply. General scheme Installation of the thermostat is similar to the sequence of installing a thermostat for an electric heated floor. However, there are certain nuances here.
The sequence of installation operations for a water heating system is as follows:
In conclusion, it should be noted that the majority modern models thermostats are universal devices. They can be successfully used not only for heated floors, but also for automating the operation of electric boilers.
If there is an infrared heater, the thermostat performs the functions of monitoring the set temperature parameters for a certain time. With its help, you can schedule preheating of the room, minimize the likelihood of a fire and create a comfortable and cozy atmosphere in the house. To do this, it is enough to know how to connect a thermostat to an infrared heater.
The functioning of the thermostat is based on a cyclic process of closing and opening electrical circuit. Microclimate regulation according to this parameter is based on signals sent by the temperature sensor. Let's look at this process in more detail:
This cycle continues for a specified time and allows us to talk about automatic installation temperature regime in a room equipped with an infrared heater. Its advantage is that it heats surrounding objects, and the thermostat makes it easier to control this process.
Despite the universal nature of the operating principle of the thermostat, there are several classifications for these auxiliary devices that determine the algorithm for their connection, control and configuration. Thus, according to the mechanism of action, thermostats can be divided into two large types:
Mechanical thermostats are simple and reliable
Reliable and easy to manage mechanical thermostats remind by appearance a plastic box with a lever that controls the temperature parameters. Adding convenience to operation is the presence of a scale, the divisions of which are marked in increments of 1 degree. Inside the device there is a sensitive membrane, the heating or cooling of which forms the basis of climate control. The popularity of these models has its own reasons:
Electronic thermostats are more modern, but require a special approach
Key Features electronic thermostats are as follows:
To increase service life electronic device Avoid direct contact with it sun rays, and also take care of the absence of drafts in the room.
Before you start connecting the thermostat, you need to make sure that conditions are favorable for its operation:
The standard thermostat connection diagram fits into the following algorithm:
If it is necessary to equip two adjacent heating devices with a thermostat, then use a parallel connection option, in which two wires also come from the panel to the thermostat, and at the output a wiring is formed to each of the heaters.
To connect two heating devices the diagram will look like this
The heater model will determine the specifics of connecting the thermostat.
Ballu is one of the most famous manufacturers thermostats
Thus, the instructions from the manufacturer Ballu contain the following important additions:
For infrared heaters of the “warm floor” system, thermostats with a remote sensor are used, which imposes its own characteristics during installation and subsequent connection:
While studying self-installation thermostat, care should be taken to comply with basic safety rules:
Thus, infrared heater, equipped with a thermostat, allows you to save energy, warm up the room in advance and facilitate the climate control process. It is important to connect the thermostat correctly to heating device. Strict compliance with the instructions guarantees safe and long-term operation of the device.
