Joey Henderson, Program Director for HVAC at Midlands Technical College and iConnect Training, uses the TU-302 Electric Board Trainer for educating students on electric heat.
What Is the TU-302 Control Board, Electric Heat Trainer?
It is a true, live 220-volt electric heat system made for HVAC educational purposes. This training unit is perfect for teaching the basics of electric heat controls systems to future technicians in a safe environment.
What Are the Components of the TU-302?
All the controls are surface mounted and include:
- Step up transformer that goes from 115 volts to 220 volts
- Sequence heater
- Fan relay
- Active, 24 VAC heating thermostat
- Fusible link
- Limit control
- Lights to simulate the 3 heating elements
This unit can also be customized with a plexiglass guard shown in this video here.
While this is a training unit, instructors and students should still exercise caution as electric shock can occur. Do not stick fingers near wiring connections.
What Lessons Can You Teach with This HVAC Trainer?
Here are a few lesson ideas for instructors to teach their HVAC students:
#1: Review electrical safety
#2: Go over the operating sequence
Point out all of the components and how each of them work.
#3: Demonstrate startup and shut down operations for the heating and cooling modes
#4: Check live voltage
Show students how to take actual voltage measurements and use the correct range on the voltmeter.
#5: Simulate blown fuses and troubleshoot
#6: 220 Volts down to 24 Volts for troubleshooting
#7: Make a call for heat to see the electrical sequencers warm up
Explain how this process works to the class as it is demonstrated.
#8: Swap out fusible links or limit controls for defective ones, and let students troubleshoot the system
This is highly recommended by Joey!
Remember, the only limitation is your imagination!
