One thermostat is a device created to control the temperature of an environment, working in a very simple but very effective way. In short, it will compare the temperature of your local with the temperature you defined as ideal. 

If the temperature is below or above the desired temperature, the thermostat comes into action to correct this, activating or deactivating the heating or cooling system. Thermostats have a temperature sensor responsible for detecting thermal changes in the environment. 

They also have a control circuit that interprets sensor information and makes decisions based on this data. If the temperature is low, for example, a thermostat will turn on the heating to warm you up.

Mechanical and electronic thermostats – how they work

There is a difference between mechanical thermostats It is electronics. Mechanics use physical components, such as a bimetallic spiral that expands or contracts with temperature. 

The electronics work with thermistors or other more modern sensors, which measure the temperature more precisely and send information to a digital circuit that controls the heating or cooling of the environment.

Additionally, the 1°C accuracy that many thermostats offer is important because it allows keep the ambient temperature very close to that that is most comfortable for you, without large variations that could be annoying or waste energy. 

Types of thermostats

On the market, you can find a huge variety of models. There are the thermostats mechanics traditional ones, which are often adjusted manually, and the digital thermostats, which display the temperature on an LCD display, allowing for more precise adjustment. 

There are also programmable, where you can set a temperature for different times of the day or week, ideal for starting the day in an already heated or refrigerated home.

You zone thermostats allow you to control several areas of the house independently, while the limit thermostats activate the heating or cooling system only if the temperature is above or below the established limit. 

In addition to these, there are immersion thermostats, used in water heating systems, and chronothermostats, which are programmable and can turn the heating system on or off according to the times you define.

How does a Wi-Fi thermostat work?

Wi-Fi thermostats are an evolution of programmable thermostats and bring a whole new layer of connectivity and control that did not exist before. This means they can seamlessly integrate with other smart devices in the home, and you can adjust the temperature from anywhere as long as there is an internet connection. 

And if you are a fan of alexa or the Google Home, you'll be happy to know that you can ask them to adjust the temperature for you, thanks to compatibility with virtual assistants. So, if your hands are full or you simply don't want to get up from the couch, a voice command is all you need to make yourself more comfortable.

Differences between smart and programmable thermostat 

The big difference is in the adaptability of smart thermostats. While one programmable thermostat depends on a pre-defined setting that you manually adjust to your desired times and temperatures, a smart thermostat does much more.

The intelligent ones have sensors and algorithms that adapt to ambient temperature in a dynamic way, learning from your habits. 

How can a smart thermostat help you?

A smart thermostat is a great help for your daily life – this type of device goes far beyond simply keeping your home warm or cool. It is capable of providing significant savings on your energy bill by adjusting the heating or cooling system as needed.
