Field Exercises
Work the scenario.
Lessons teach you how things work. Exercises put you in front of the problem. Troubleshoot faults, commission controllers, and build real sequences on a live wiresheet.
Troubleshooting Scenarios
Something's wrong. Figure out what.
Power Check
Free PreviewController at RTU-3 is unresponsive. Track down the fault using a multimeter.
Sensor Check
A sensor is reporting a bad value. Open circuit, short, drift, or config mismatch?
Actuator Check
A damper actuator isn't moving. Is it the signal, the power, or the actuator itself?
BACnet Check
A controller dropped off the MS/TP network. Find the communication fault.
AHU Not Economizing
Conditions look right but the outside air damper won't open.
Zone Temperature Off Setpoint
A zone is consistently too hot or too cold. Work through setpoint, sensor, airflow, and sequence.
Point-to-Point Checkout
Commission a controller. Verify every point. Test every safety.
Basic AHU
A controller wired per submittal. Verify every input, override every output, and test the safeties.
Programming Exercises
Wire blocks together. Run the logic. Watch values propagate.
Programming Sandbox
Open wiresheet with a live sim engine. Add blocks, wire them up, hit Run.
Rooftop Unit Control with Economizer
Build the fan, economizer, cooling, and heating sequence. Test against a simulated day.
