Runnable simulator field guide
PLC simulator for HVAC: test checklist
Direct answer
The learner can run an HVAC sequence, diagnose a failed boundary and explain transfer limits to a real BAS or PLC project.
Written for building automation and controls learners practicing fans, pumps, dampers, valves, temperatures, pressures and safeties.
Scenario setup
Served zone, equipment, modes, occupancy, sensors, actuators, safeties, setpoints, proof, alarms and reset policy.
I/O and state map
Mode demand through permissives, fan or pump command, damper and valve position, feedback and environmental response.
Normal run
Occupied startup, stable control, mode change and controlled shutdown from declared conditions.
Boundary run
Freeze, smoke interface, lost airflow, failed damper, sensor fault, utility loss, simultaneous demand and restart.
Injected fault
A mode, permissive, command, actuator, feedback, loop, instrument or process-response mismatch.
Target check
The sequence reviewed against approved design documents and commissioned on the actual building system.
