Connecting the thermostat to the boiler

The most common source of heat in a modern private home (if you do not take into account adherents of traditions and romantics who prefer a Russian stove or fireplace) is a heating boiler. Most modern boilers are powered by electricity or use gas fuel; solid fuel and other models are less popular.

Connecting the thermostat to the boiler

An ordinary heating boiler, relatively speaking, in the basic configuration, operates in manual mode. The heating device has a temperature regulator, which remains unchanged until switching. The device itself does not react in any way to changes in room temperature. If during the daytime, being in the house, it does not seem like a big problem to approach and turn the knob is not difficult, then a sudden cold snap at night, as well as a drop in temperature during the owner’s absence, may turn out to be an unpleasant surprise.

A thermostat helps to avoid such troubles. This is a device that is capable of automatically monitoring the room temperature and maintaining it at a given level. The simplest solution is to purchase a thermostat complete with the boiler. Manufacturers often offer such kits; their advantage is the absence of connection difficulties. But what to do if it was decided to connect a new thermostat to an existing boiler?

How to properly connect the thermostat to the boiler

You need to decide on the type of device. It can be mechanical or electronic - usually for gas and electric boilers, respectively.

Connection diagram

1. A mechanical thermostat does not require connection to a power supply - its operating principle is based on connecting and disconnecting electrical circuits. The switching moment determines the selected temperature value. The process is controlled by the movement of a membrane that reacts to heat. The general connection diagram will look like this:

Important! To prevent installation of the device from becoming a fascinating puzzle in a slowly cooling room, you should find instructions for connecting a specific thermostat model - in the instructions for it, on the back of the cover or on thematic resources.

2. An electronic thermostat is more accurate - temperature changes are monitored by a sensor, the accuracy of which is much higher than that of mechanical devices. Moreover, even inexpensive models have an expanded set of functions, for example, linking a specific temperature regime to the time of day. Due to the fact that the device is connected to the general network, a two-wire cable is used. An approximate diagram is as follows:

Important! The correct technical data sheet for a heating boiler usually contains all the necessary information about connecting additional equipment, in the form of step-by-step instructions and visual diagrams. Familiarization can make the task much easier.

Setting up the thermostat after connection

After successful connection, all that remains is to configure the device. On advanced models there is a programmer with which the settings are made. Can be adjusted:

• heating and cooling (air conditioning) temperature;
• delayed response of the sensor to temperature changes (useful for ventilation and frequent drafts);
• sensitivity of the device;
• setting two or more temperature modes.

The ability to fine-tune the values ​​of optimal and economical temperature conditions is not the least important. A device that automatically switches to an economical mode (lowering the temperature to a predetermined possible threshold) saves electricity - in large quantities. Some models have large differences in energy consumption even with a minimal difference in values.

Connecting a thermostat with a thermostat

Many models of modern thermostats are a set of a control unit and a thermostat. Thermostat is a device for remote control of a heating device, located in any convenient place. The temperature selection is transmitted to the control unit connected directly to the boiler. There should be no issues with connecting a simple thermostat; What do you need to know about installing a room thermostat?

The first step is to choose not the device itself, but the location for its installation. It should be located:

• at a sufficient height from the floor - about one and a half meters. The point here is not about convenience, but about physics - the sensors of a low-lying thermostat will capture the heat of the heated floor and set a low temperature;
• at a distance from possible sources of heat, be it sunlight, heaters or stoves. The logic is the same;
• on the inner wall of a room where there is enough open space - and again not for reasons of comfortable control of the device. For correct operation, the device must have access to air flow - circulation makes it possible to evaluate temperature changes and adjust the operation of the boiler.A thermostat covered with a curtain for reasons of aesthetics will not bring the expected result.

The method of connecting the thermostat to the unit can be wired or wireless. The former are distinguished by their affordable price and the absence of signal problems; wireless ones are more expensive, but eliminate the need to lay another cable.

Important! It is worth carefully weighing the decision to purchase a wired device. Connecting a new wire over the repairs made can make you change your mind at the most inopportune moment.

The advantage of a device with a thermostat is its expanded functionality. Installation of modern models in terms of labor costs is quite comparable to a conventional thermostat, but in the end it gives more advantages:

• customizable temperature modes;
• clear interface with date and time display;
• minimum number of boiler starts;
• the most precise calibration of sensor operation;
• high reliability.

The main thing is that the thermostat eliminates the need to manually regulate the operation of the boiler, allows you to configure the device remotely and significantly reduces the amount indicated in the bills for paying for electricity.

The right approach to choosing a thermostat will allow you to completely forget about the problem of heating your home.
