Description of the device:
3 control buttons: set, +, - .
set - selects the installation mode and parameter settings
+ and - change the value of the setting and parameters

In C (cooling) mode, it works as follows: while the temperature is below the setpoint, the relay contacts are open, when the set temperature is reached, the relay contacts close and remain in this position until the temperature drops by the value of the set hysteresis (by default, 2ºС).
In H (heating) mode, it works the other way around

If you press the "SET" button, then using the "+" and "-" buttons you can set the temperature for switching on the relay (if the current temperature is LOWER than this value, then the contacts of the power terminals are closed.)
The thermostat must be paired with a heater or cooler.

To set the control temperature, press the SET button, then use the "+" or "-" buttons to set a new temperature, and press the SET button again.

To enter the programming mode, hold down the SET button for 5 seconds, then use the "+" or "-" buttons to select a menu item from the list below. To save the settings, press and hold the SET button, or do not press any buttons for 10 seconds. To return to the default settings, press and hold the "+" button.
