Both automated methods (by sensors, time, etc.) and manual methods are used to control the processes in the Smart Home, using switches, dimmers, contactless sensors, and a mobile application. Thus, in manual mode, you can control not only the inclusion of lamps, curtains, but also the climate in the house.

Of course, you can set a comfortable temperature in the mobile application. But sometimes it is more convenient and faster to press a key or turn the knob.

It is for such cases that universal thermostats are created - devices, usually wall-mounted, designed to manually adjust the microclimate parameters indoors and with the ability to display on the built-in screen current and set values ​​of these parameters, as well as auxiliary information - mode, time, date and more. Based on the versatility of such thermostats, manufacturers have created many models with appropriate built-in sensors (temperature, humidity, air quality) outputs (relays, 0-10V interface, etc.) and interfaces for data exchange with other devices. Such thermostats are usually full-fledged controllers for climate control and directly control the actuators.

For Smart Home systems based on Atom series controllers, this thermostat functionality is redundant. After all, actuators are connected to the outputs of the controllers. Therefore, in order to manually set or change the desired temperature or humidity, a simple device with controls (keys or rotary knob), display and interface for communication with the controller is enough.

Today, touch screen thermostats (models with temperature, humidity and carbon dioxide sensors) and a rotary regulator (with temperature sensor) are available. The wired RS-485 interface is used to communicate with the controllers.
