Description
The TU-9240 HVAC Electrical Control training unit gives students the opportunity to learn the basics of electricity, and then proceed on to learn how to set up a control circuit. It is designed for courses teaching the apprentice or vocational student early in their training. Built on a rolling frame with 36 modular panels, the instructor can position 12 panels on the front display for the lessons of the day. All refrigeration controls used are all designed for the HVAC industry. The student can learn from connecting the controls using two different methods, depending on the panel:
Plug and play type: plug the wiring into the jacks and build the circuit from that point.
Direct wiring: using terminal strips, by cutting and running the wire, and then terminating at the control, as they would in the field.
The instructor can teach the principals of circuitry, all with this low voltage system (24-volt) to ensure beginner safety. Students can experience taking voltage, amperage and resistance readings to build their basic understanding of an electrical system. Lessons off this unit will also teach them basic knowledge of series (as seen in pressure controls) and parallel circuitry (as seen in relays).
