The indirect heating unit control system monitors the operation data of the primary, secondary side temperature, pressure and electrical equipment, the purpose of controlling the heat change and the secondary cycle is achieved by adjusting the opening of the backwater electric regulating valve and changing the frequency of the circulating pump transducer, realizes the heating demand of high efficiency and high quality. System has the incremental fuzzy PID control, self-learning control function, fault detection and security protection, automatic climate compensation control, time control model...
