The student will be able to:

1. Explain the operation of an electronic control system
2. List the advantages semiconductors have over vacuum tubes
3. Describe the function and operation of common types of diodes
4. Describe the function and operation of common types of transistors
5. Describe the function and operation of common types of thyristors
6. Describe the function and operation of integrated circuits
7. Identify common considerations for troubleshooting semiconductor devices
8. List common applications of electronic control systems

1. Explain the operation of an electronic control system
   1. Describe that an electronic control system is a control system in which the power supply is 24 VDC or less
2. List the advantages semiconductors have over vacuum tubes
   1. Describe how a vacuum tube is a device that switches or amplifies electronic signals and that vacuum tubes perform these functions by allowing electrons to flow to plates that are located inside a glass tube
3. Describe the function and operation of common types of diodes
   1. Explain how a diode is a semiconductor device that allows current to flow in one direction only
4. Describe the function and operation of common types of transistors
   1. Show how a transistor is a three-terminal semiconductor device that controls current according to the amount of voltage applied to the base
5. Describe the function and operation of common types of thyristors
   1. Explain how a thyristor is a solid-state switching device that switches current ON by a quick pulse of control current
6. Describe the function and operation of integrated circuits
   1. Describe how an integrated circuit is an electronic device in which all components (transistors, diodes, and resistors) are contained in a single package or chip
7. Identify common considerations for troubleshooting semiconductor devices
   1. Explain how the most common electronic circuit troubleshooting situation is to find the correct printed circuit (PC) board, determine if the board has a problem, and replace the board if necessary
8. List common applications of electronic control systems
   1. Describe how electronic control system components include sensors and electronic thermostats that are used in applications such as multi-zone unit control, boiler control, and chiller control

Students will build an operational electronic control panel.
