Outdoor or indoor thermostat for Baxi gas boiler: what to choose?

A thermostat is a temperature-regulating device that is responsible for control of boiler operation depending on air temperature.

There are thermostats indoor and outdoor (outdoor) Sensors can also be used for the street.

Baxi gas equipment has the ability to connect both indoor and outdoor thermostats and sensors.

Indoor appliances have a greater impact tactfulness (switching on and off) the boiler, and the street ones allow the unit to regulate coolant temperature. The air temperature outside and inside the house is constantly changing, and the thermostat helps increase or decrease gas consumption for heating premises.

Types of thermostats for Baxi gas boilers

Baxi devices are thermostats, compatible with gas boilers of the Italian brand.

In their functions, they do not differ from systems for other gas equipment. Thermostats are usually distinguished by:

• installation location;
• operating principle;
• management method.

According to the place of installation, the devices are divided into indoor and outdoor. Indoor ones are used more often than outdoor or street ones, since they do not require protection from difficult weather conditions.

Outdoor options are used in cases where the owner of the house seeks to make the equipment work as accurately and economically as possible. The combination is especially effective in such cases room thermostat and outdoor sensor, which Baxi units allow.

According to the operating principle, the thermostat can be mechanical or electronic. In the first case It is necessary to set the air temperature manually. In the second — a program is set up according to which the boiler changes the intensity of operation automatically.

The method of controlling a mechanical thermostat is to manually set the mode by turning the knob or pressing buttons. The electronic or programmable version can operate remotely. In this case, the sensor is located in any part of the room, and control is carried out from the remote control, via computer or telephoneIn this case, contact with gas equipment remains wired.

How to choose a Baxi thermostat

Thermostats and sensors for gas boilers Baxi produced by the Italian company itself, so it is best to choose them. If this is not possible, you need to look for a thermostat that fits the parameters that are usually specified in technical data sheets of devices. In such cases, it is appropriate to seek advice from a specialist who is familiar with the Baxi brand.

When choosing a thermostat, it is necessary to consider whether the boiler is used constantly or only from time to time. If the house has an inexpensive model of the unit that works rarely, then it is enough a simple regulator with a minimum of functions.

Conversely, if heating and hot water supply are needed all year round and an expensive model of the unit is used, it is better to install a programmable thermostat.

And if the cottage is used smart home system, then the ability to control the device via the Internet will come in very handy.

This feature is implemented in most advanced models.

The calculation of technical requirements for the thermostat is made based on the requirements for the operation of the boiler. For example, if the owners leave for work in the morning and return only in the evening, it will be suitable thermostat with programmer, which will reduce the heating temperature and fuel consumption while there is no one in the house.

Also, if the house is geographically located in a cold region, it is better to purchase a thermostat with protection against freezing of the system: it automatically turns on the boiler if the air temperature drops up to +3°C. For example, the following have such technical characteristics: Baxi Magictime Plus room thermostat.

Where to place

An important condition for the proper operation of thermostats is the accurate measurement of air temperature. Although all devices have an error up to several degrees, it can be reduced to a minimum.

For this, a room thermostat must be installed away from drafts and at a considerable distance from heating devices.

It is better to install the outdoor sensor so that it is not flooded by rain or covered with snow. These precautions are due to the fact that more precisely, the sensor readings, the more efficient the boiler operation and the lower the fuel consumption.

What materials are needed for connection?

Connection materials are usually supplied with the thermostat. This is, first of all, the device itself, as well as installation cable and fastenersWith their help, the device is connected to the gas boiler and fixed to the wall.

What tools are required for installation?

To connect the thermostat you may need:

• screwdriver;
• drill;
• side cutters;
• thermometer.

With side cutters You can strip the ends of the thermostat wires, but as a rule, they already have terminals that are screwed to the contacts of the gas boiler for the remote thermostat.

A drill is needed for the holes in the wall into which the dowels are installed. They are screwed into screws, on which the device is attached. The need for dowels It is not possible if the wall is wooden.

A thermometer will be needed to check the air temperature after starting the thermostat.

Connection procedure

During the connection period, both devices should not work. To connect the thermostat and the gas boiler, you need to study technical data sheets of both devices and follow the diagrams and instructions for connection. The ends of the cable for the thermostat must be attached to the intended gas boiler contacts.

Then the cable needs to be pulled along the wall to the place where the thermostat is installed. After that, at the selected point (usually it is in the coldest living space), the device is screwed to the wall. Finally, setting up and checking the device.

How to check the operation of the device

To check the device, you need to set the maximum temperature. Then you need to turn on the gas boiler and bring it to maximum efficiency mode (efficiency).

Once a comfortable temperature is reached, it is necessary to measure it accurately near the thermostat and set it as a threshold for switching off.

Then, within an hour, you need to monitor whether the thermostat turns on the heater when the air cools down. within 0.5-2 °CIf this happens, the devices are working properly.

How to make your outdoor or indoor thermostat work efficiently

The main tasks of the thermostat include maintaining a comfortable temperature and saving fuel. This, in turn, allows reduce gas costs and reduce equipment wear and tear.

To achieve maximum effect, experts recommend installing both a room and an outdoor thermostat.

However, it is believed that for the optimal operation of gas equipment it is quite sufficient room thermostat.

Before its installation, as well as before the operation of a gas boiler, the house must be prepared: the cracks must be sealed and the temperature in the rooms must be measured.

These devices will be of some use only when heat loss will be reduced to a minimumTo ensure comfort for the residents of the house, it is recommended to maintain an average air temperature in the living quarters. +20 °C. In this case, it is better to maintain the temperature in the nursery. +22 °C. At night, the optimal temperature range for the thermostat to operate will be from 19 to +20 °C.
