(2) Touch screen human machine interface (HMI) program
The touch screen replaces some functions of the mouse and keyboard. The input device installed at the front end of the display screen is the medium and dialogue interface for transmitting and exchanging information between people and the control system, including long-distance information transmission and control. It is an important part of the control system. Add the switching value into the PLC control program and associate it with the register of HMI to realize the association between HMI and PLC, as shown in Figure 5.

6 Conclusion
This application realizes the automatic control and monitoring of the hot water system through Delta PLC and its touch screen. The addition of auxiliary heat source solves the disadvantage that a single solar energy is greatly affected by weather conditions (if the auxiliary heat source adopts air source heat pump, the system has significant advantages of low power consumption, safety, comfort,
