Abstract: Today, the issue of the economical use of energy sources is actual in the world, because of their significant price increase. Users should choose the heating method and system that is most effective in terms of safety, components costs, installation and commissioning, ergonomics, etc. Electric heating systems meet all these requirements. Despite the wide selection of modern heating elements, working with them is impossible without using a heating control system. All heating element systems are controlled by measuring the temperature of the coolant or the surface of the heating element. The high thermal inertia of the heating element makes it difficult to maintain the thermal regime. Knowing the main shortcomings of heating element control systems, it is proposed to create a virtual microcontroller system for the relay power supply of the heating element. This can be achieved by using a microcontroller for control, which will be able to evaluate the information and generate control pulses to turn on the DC source. This method of controlling the heating element will be carried out programmatically, without human intervention. For the development of a virtual microcontroller relay power system, theoretical foundations have been developed that take into account the capabilities of the experimental setup. To check the adequacy of the modeling, a comparison of the processes of heating (cooling) the heating element and charging (discharging) the capacitor was performed. A block diagram of the simulation program of two complete heating and cooling circulations has been developed. To check the operation of the virtual microcontroller system of the relay power supply of the heating element, the following was performed: simulation of two circulations of complete heating and cooling on an experimental installation; simulation of a gradual decrease in the temperature of the heater with three control pulses. Ways of further research are planned.
