Kit sets of thermostats are semi-finished modular electronic components from a circuit board and built-in electronic elements such as resistors, capacitors, relays, some with LED display, which are already configured. Their main job is to measure informational temperature amplitudes or by means of an electrical signal to control the switching on and off of various electronic devices. They can be designed as stand-alone electronic devices or be part of automated electrical circuits such as an electrical switch and start and stop various electrical devices depending on set parameters for the ambient temperature.
