This paper presents a novel HVAC automated control system built on a programmable logic controller. The system was designed using one of the IEC 61131 programming languages being used for programming PLCs. It means a significantly wider range of control options compared to conventional systems. Also we propose an upgrade option for an air supply unit with water heating, the key idea of which is implementing qualitative control instead of quantitative one. The mixing part including a three-way valve and recirculating pump provides control of heater water temperature lowering possibility of occurring frost under low temperatures.
