Thermostat for underfloor heating : Step by step instructions on connecting

thermostat function in heated floor systems consists in the switching on and off of the heating circuits and the regulation of the degree of heat.Use thermostats can significantly save on your calculations for heating, to avoid unnecessary costs, including the system only when you need it.

Basics

Heated floors can have a different design.Heat can be transferred by liquid coolant (hot water or antifreeze solution), and extracted directly from the cell system with an electric current through the heating cable or infrared film.In any case, the degree of heating circuits regulated by the temperature regulator.

temperature control heated floor can be mechanical or electronic.In the first case, the heating degree is adjusted manually by turning the rheostat control knob.The second is responsible for the regulation of electronic relay.The electronic temperature controller can also be software components, allowing you to enable or disable the heating circuits at a certain specified time.

thus looks mechanical temperature control:

And here's what a thermostat with an electronic programmable unit:

thermostat can be overlaid installed on the mounting bracket and cover the body with a mechanism:

and embedded, which is recessed in a prepared niche in the wall:

thermostat in the electrical system of the heated floors are usually connected to the power wiring of the room.It is recommended to use a separate circuit breaker for its connection.

In cases where the system heated floors installed in areas with high humidity - the thermostat can be put in another room.

In addition, a separate type thermostats for heated floors are devices controlled by radio.In this case, the thermostat itself and its remote control unit may be in different locations.

Setting the thermostat

Consider installing embedded thermostat for electric underfloor heated with a heating element - the electric cable.

Please note that the supplied heat-insulated floor there are two cables.One of them - it is actually the heating cable, and the second is designed to connect the heating cable to the thermostat of the heated floor.

Supplied thermostat is a temperature sensor, which has a view of the wire with a sensor on the end.

And close-up simple mechanical thermostat:

Here is the junction box located on the back side of the thermostat:

Systemheated floor with an electric cable can be equipped with two-core and single-core cable.Depending on the number of veins on the terminal box thermostat terminal connectors are located.

In any case, the terminal box are connectors for the temperature sensor for the heating of the cable for connecting the power voltage from the mains.

Note the markings liner wiring.The terminals are marked «L» - the respective phase and the designation «N», is zero.

So, electric heated floor, we already laid and the red heating cable is connected to the black cable connector.

Wire connection (connection and sensor) to the appropriate terminalson the thermostat:

turn the thermostat (on his body caught fire warning light (and check the performance of the heated electric floor:

Choice of thermostat

The most important thing in choosing a thermostat - a line of its power and the power of your electric heated floor common household electrical outdoor lighting system have a capacity of about three kilowatts..

Connecting multiple thermostats

Need to connect multiple thermostats can be you, if you want to split the room into zones in which different temperature conditions must be maintained.Also, you have to buy and install multiple thermostats, if stacking is heated by electric floor total capacity will exceed the capacity of the thermostat.

thermostat for the floor with liquid coolant

In some cases, when installing heated floors to the heat transfer fluid does not set any temperature control system.The heating circuits are simply connected to the main system or individual heating through the collector.On some models, the collectors are adjustment screws that can perform thermoregulatory function

Temperature regulators for the heated floor with liquid coolant act indirectly.Based on the temperature measurements they provide servo command that limits or increases the coolant flow.As a result, electric heated floor thermostat regulates on the team almost immediately, and the system with heat transfer fluid - with a noticeable delay, when the coolant reaches and warms the heating ducts.

Temperature Controller types in systems with heat transfer fluid

The simplest kind of thermostats for underfloor heated heat transfer fluid is mechanical, which simply restrict the water flow in the heating circuits.Similar devices are usually mounted on conventional modern radiators.The user sets the desired flow (and hence temperature) manually by turning the head.They are simple and inexpensive, do not require continuous maintenance and have a long service life.

The electronic thermostat for systems with heat transfer fluid has an electronic unit which is connected to a temperature sensor.The sensors can measure both the indoor temperature and coolant temperature directly.They may also have the function of programming and switched on and off for periods of time and at the temperature which is set by the user.

To send a signal from the thermostat to the actuator can be used both wired and wireless links.

You can select a specific type of temperature-control systems, depending on your needs, the design of the heated floor and your budget.
