Connecting the thermostat to warm the floor

In underfloor heating systems, the role of management control unit plays a thermostat - a device that processes the information received from the temperature sensor, and in accordance with the specified mode to enable or disable the heating of the floor.

With electric underfloor heating system thermostats set mandatory.Set the thermostat in the system of water underfloor heating is not required.But if the floor heating is optional measure, and wherein the coolant temperature at the entrance to the contour of above 50 degrees, the installation space thermostat solve the problem of overheating.

Types of thermostats

Thermostats for any floor heating system can be:

• programmable operating at a predetermined, including challenging program;
• without software control.

Changes in non-programmable thermostats modes is done manually using the rotary control (manual control) or the buttons (electronic digital).

Programmable thermostats are more expensive and more difficult to manage, but it can significantly save energy by turning off the floor heating or lowering its temperature at night or during the day when it does not need heating.

mechanical non-programmable thermostats are controlled by a simple turn of the handle to the specified mark.Electronic digital - with the buttons, touch panel or remote control.Price non-programmable thermostats lower due to the simple logic part.

By way of installing thermostats are:

• embedded - they are placed in a special recess in the wall;
• overhead - they are fixed to the wall with screws or screws.

Selecting the type of installation - a matter of taste, but it does not affect the functionality.

sensors for measuring

temperature sensor is a thermocouple two wires, modifying circuit resistance when heated.Wires are connected to the appropriate terminals thermostat.Sensors are:

• outrigger;
• built.

Remote divided into a floor sensor or air.The first mounted at the same time laying the heating elements right under the topcoat, the second - in a comfortable air temperature measurement location.Built-in sensors are located directly inside the thermostat.Some thermostats models have both types of sensors.

The bathroom and the kitchen is better to install thermostats floor sensor - the air in these rooms can be heated from the stove or hot water, the floor thus remains cold.

Connecting the thermostat to the electrical warm floors

Electric underfloor heating performed by the heating cable with a high resistance or infrared film.They are placed on a specially prepared surface, then make a floor screed and laid topcoat.

Connectivity technology thermostat:

1. Until floor installation is necessary to determine the place where the thermostat will be located, and plan to connect it to the mains.To connect the thermostat must be 220 V AC, it is possible to connect it to a normal outlet or a separate cable through the circuit breaker.
2. When laying the floor chosen location for the temperature sensor.It should be located far away from the thermostat, on the free floor area of ​​the furniture.

1. infrared floor sensor is placed on the reverse side of the film and is connected to the wire going to the thermostat.
2. For cable underfloor heating, screed concrete is poured, the sensor must be put in a metal corrugated pipe, isolating it from falling concrete.This measure is necessary for easy removal and replacement of the sensor in case of failure.Immured in concrete sensor just will not work to remove.Pipe output to a wall on which the thermostat is set.
3. After laying the floor ready to install the controller.The chosen location is prepared recess in the wall the size of the body concealed thermostat or doing layout for fixing the applicator.Remove the front panel and secure the controller in place.
4. compares permissible power handling capacity of the thermostat contact with the heating cable or infrared floor.If it is less - further establish magnetic contactor coils rated at 220 VAC.In this circuit the heating cable is connected to the power supply 220 through the contacts magnetic starter, a starter coil circuit is connected to the output of the thermostat.
5. If the switching capacity of contacts thermostat enough, the heating cable is connected directly to the output from the thermostat.
6. plug-in sensor circuit to the terminals indicated in the passport or instructions.
7. connect the power 220 to the corresponding terminals: they are usually referred to as L or F - phase and N - zero.Phasing must be observed.Identify it can be the color of the wires: if the cable is laid on the new and the rules, the phase wire has a black, brown or white insulation and zero - blue.If you connect the thermostat to a common outlet, phase voltages are using a pointer or indicator screwdriver.

• Check thermostat operation:
• Serve food 220;
• sets the minimum temperature value at the thermostat;
• Includes floor heating tumbler;
• varying heat mode to maximum by turning the knob or buttons - in this case must be heard click, informing about the closure of the heating circuit.

Connecting thermostat to warm water floors

Temperature regulators for water floor heating systems are a device for servo control, regulates the flow of coolant in the heating circuit.They may be electronically or manually controlled, with such control systems are commonly used temperature measurement sensors, not the floor, due to the great heat inertia.

1. sensor mounted at a height of about 100-120 cm above the floor on the wall, can be next to the thermostat.The wall must be subjected to additional heating from radiators.
2. Mount the thermostat power circuit and sensor circuit.
3. If a thermostat with electrical connection to the servo - Route the cables to the chains of its management.
4. When using the controller with radio tune it.
5. verify the operation control system produced by an external thermometer: set on the regulator desired mode and measure the temperature at the site of the sensor for a few hours.The temperature should not vary significantly.

All work for connecting electrical circuits must be performed when the circuit breaker - is the key to your safety!
