---

- Practical demonstrations with supervisor observation and sign-off on each key task

- Successful completion of commissioning checklists with zero critical deficiencies

- Written exam on troubleshooting methodology and control sequences (80% passing score)

- Calibration verification by comparing results against known standards

- Customer satisfaction scores (minimum 4.5/5.0 on service calls)

- Peer review from senior technicians and Project Managers

- Portfolio of commissioned systems and resolved service issues

-------------------------------------------------------------------------

**Key Tasks for Qualification**

- 1. **Installation & Termination:** Accurately pull and terminate control wiring (including shielded twisted pair) for at least 10 field devices (sensors, valves, dampers), maintaining compliance with local codes.

- 2. **Installation & Termination:** Mount and wire DDC (Direct Digital Control) controllers within a control panel, ensuring correct power supply and grounding procedures.

- 3. **Commissioning & Calibration:** Execute the full commissioning checklist for an AHU (Air Handling Unit) or Boiler plant, proving that all physical inputs/outputs are correct.

- 4. **Commissioning & Calibration:** Calibrate at least three different types of sensors (e.g., temperature, humidity, static pressure) to within 1% accuracy using a calibrated standard meter.

- 5. **Troubleshooting & Service:** Diagnose and repair a low-voltage electrical fault (e.g., short circuit, broken wire, faulty relay) without causing system damage.

- 6. **Troubleshooting & Service:** Utilize a multimeter and other diagnostic tools to prove out the mechanical operation of a modulating valve or damper actuator.

- 7. **Documentation:** Complete daily field reports (DFRs) detailing work performed, materials used, and safety concerns.
