The study analyzed the heating system and hot water supply with  using renewable energy sources. To design an automatic control system for heating and hot water supply, which includes a solar collector, a heat pump and a centralized heating source, the following tasks were set: - study of scientific literature on the operation of renewable energy sources; - design of a structural diagram of the automation section; - design of an algorithm for controlling the heating system and hot water supply. The relevance of designing a control system for an object with a variable structure is shown. As an automation object, the system of heat supply and hot water supply with the use of renewable energy sources is considered. The possibility of sharing a heat pump, solar collectors and a centralized source of thermal energy for heating and hot water supply was explored. The technological scheme, the automation scheme, the control algorithm, the software of the complex are designed. The proposed algorithm for controlling the heating system and hot water supply realizes the cascading operation of equipment with the priority of switching on renewable sources of thermal energy to solve the problem of reducing energy consumption. The software of the developed control system and simulation of the heating and hot water supply system was implemented in the programming environment of the controller ОВЕН ПЛК160. For technical implementation, modern automatic control system devices and renewable sources of thermal energy have been selected. The management of automation tools, data collection and visualization is carried out with the help of SCADA-system WebHMI, operating in the real-time operating system. The obtained results of simulation are confirmed by the introduction and successful operation of the designed automatic control system at the municipal enterprise of the town of Yuzhniy. The joint work of renewable sources of thermal energy and boiler equipment under the management of the developed management system has proved its energy efficiency both during and outside the heating season, and it makes it possible to achieve 30% savings on heating and hot water.
