How Does a Digital Thermostat Work?

However, in general, these devices rely on electrical sensors that control temperature changes: based on these changes and the temperatures that have been programmed, the thermostat turns the heating system on or off.

Where Is It Best to Place the Digital Thermostat?

First of all, it is better to place it away from sunlight, so that this does not affect the temperature reading and, therefore, the operation of the device.

Similarly, it is better to keep it away from appliances that can be a source of heat or that cool the environment. Lastly, it may be better to install it in a room where there is enough activity, and at the height of 1.50 m to 1.80 m.

So, a key aspect to consider of these apps is the ease of their interface, especially if they are to be used by people who are not very practical with new technologies.


Digital thermostats have various additional functions, which go well beyond temperature control: the most common one allows you to program their on and off. Some are security functions to ensure that the system is turned off under certain conditions.

A new function allows you to use the zone heating system: some thermostats also offer a history of data on consumption, temperatures and on and off times. There are also smart features for returning from vacation or that adapt to our daily habits.
