Servo for underfloor heating manifold

Among the numerous equipment involved in the operation of such a heating system as a “warm floor”, you can find a small device that plays an important role in controlling and adjusting the entire circuit. This device is a servo for the collector of warm water floor - a mechanical device, without which it is impossible to automatically adjust the temperature for a water floor heating. How to choose such a detail - we will consider in this article.

Types and classification of devices

Currently, manufacturers offer these types of devices:

• Mechanical. Of the main advantages, high strength and affordable cost of the product can be noted. Absolutely no skills in using such a servo drive are needed - this is a simple device that provides temperature control by turning the wheel. Also, there is no need for constant monitoring of the mechanism - all work takes place offline. However, there is a drawback, namely the impossibility of programming the most optimal temperature. Here you need manual tuning, which can be quite time consuming.
• Electronic. This is equipment that has advanced functionality. The electronic display of the device will show the operation of the system, the correctness of all running processes, the absence or presence of malfunctions. Convenience of temperature control, ease of control, the ability to automatically adjust - all these are the advantages of such a device. Minus - a fairly high cost.
• Remote. Equipment that makes it possible to make all the settings without even touching the collector itself, and indeed, being at a distance from it. For the sensor, all processes of the system are monitored qualitatively, operate in 9 different modes, and can function in the absence of a person in the room for a long time.

Important! There are installation requirements: the servo must be from the same manufacturer as the underfloor heating system itself.

Servo drives are also divided into:

• Normally open - in the absence of voltage it is in the “open” position.
• Normally closed - in the absence of voltage or coolant supply, it is in the “closed” position.

Important! Today, universal devices have begun to appear on the market in which the “normal” position is set, depending on the requirements of the system, and makes it possible to change from “open” to “closed” state.

What affects the choice of equipment?

Choosing a servo for a warm floor system, you need to determine what condition this equipment will be in most of the time, and with other nuances:

• If it is necessary that the coolant circulates constantly, then it is better to pay attention to the normally open view of the device.

Important! In regions where severe frosts occur, normally open servo drives are installed. The advantage of such equipment also lies in the fact that during power outages, breakdowns of the servo drive, the system will still be supplied with coolant and the floor will be warm until the water in the collector is heated.

• Normally closed types of equipment are preferably used in regions with a warmer climate, where in the event of a breakdown of the mechanism or power outages, disconnecting the system from the heat supply is not so tragic.
• It is useful to know that among the existing models of servo drives there are devices with smooth tuning. Additional supply of electronic type regulator allows you to achieve the desired voltage. It is worth using such equipment in cases where it is necessary to supply a metered flow movement.

Important! When buying a servo, you must always take into account the installation requirements of the electronic controller. If the device is needed, it means that you are dealing with a thermionic drive, the use of which in a warm water floor system is impractical.

• The right choice of heating servo depends not only on the appearance, its type, but also on compatibility with the thermostat. By choosing a universal device, the user will receive convenient control of the servo drive, regardless of the open or closed type. Installation of such a device is quite simple and should not cause any questions.
• As for the assortment, it is better to give preference to brands of world-wide stable manufacturers, which have proven themselves in quality and ease of use. For example, this is an Emmeti floor-mounted servo-drive - a manufacturer from Italy brought his equipment as close as possible to the realities of our lives, which ensures excellent operation of the water heating system. In addition, such servo models for water floor heating manifolds have a lot of functions and affordable cost.

Important! When arranging such a heating system, it is necessary not only to correctly select high-quality components, but also to assemble them. About suitable pipes, laying schemes and installation principles read in our article "How to make a warm floor?".

Connection Features

Improper installation of equipment can lead to the fact that the system stops heating the floor and simply crashes. Therefore, before installing the servo, it is worth considering some points:

• Place of installation - manifold valves. There is no specific place or scheme, it all depends on the model and type of thermostat.

Important! Choosing a device for controlling one circuit, the work can be carried out directly. If you have to control several circuits, it is better to lead the wires into the intended terminals.

• Popular types of devices are equipped with two wires: the first is phase, the second is zero. The absence of a phase conductor indicates that the function of this servo is the same - the device either only heats the valve or only closes it.

Important! Do not forget that not every coating can be laid when installing a warm floor. About what options are available and what is better to choose, see the information in the publication “Which flooring is better for a warm floor?”.
