Fundamentals
PID Control Loop Simulator
Tune P, I, and D gains against a live simulated coil and watch stability, overshoot, and hunting respond in real time.
Open lab →Psychrometric Process Calculator
Plot states and processes on the psych chart — mixing, cooling, dehumidification — and sanity-check "impossible" sensor readings.
Open lab →Control Signal Scaling & Fault
Scale 0–10 V / 4–20 mA signals to engineering units, then diagnose injected scaling and wiring faults.
Open lab →Point Types & Priority Array
Command a point at different BACnet priorities and see exactly why an "ignored" output is really an arbitration fight.
Open lab →Troubleshooting Simulator
Probe an AHU loop with a virtual meter and isolate the injected fault using the Errors & Flow decision tree.
Open lab →Reading Mechanical & Control Drawings
Navigate real-style drawing sets — plans, schedules, details, and points lists — and answer field questions from them.
Open lab →Systems & Sequences
AHU Economizer & G36
Operate a G36 economizer through changeover conditions and prove when free cooling should (and shouldn't) engage.
Open lab →Trim-and-Respond Static Pressure
Run the G36 trim-and-respond reset against changing zone requests and watch fan energy fall without starving zones.
Open lab →Central Plant Staging
Stage chillers and pumps against a building load profile; bad staging shows up immediately in energy and stability.
Open lab →Zone Deadband & Optimum Start
Set deadbands and optimum-start parameters, then watch comfort and runtime trade off across a simulated day.
Open lab →Alarm Rationalization
Turn a flooding alarm system into a useful one — priorities, delays, routing — and prove the flood can't recur.
Open lab →Demand-Controlled Ventilation
Drive CO₂-based DCV through occupancy swings and verify ventilation compliance against the sequence.
Open lab →Smoke-Control Sequence
Step a smoke-control sequence through detection, pressurization, and reset — where the SOO is life-safety law.
Open lab →Networks & Cybersecurity
BAS Network Topology
Build and break BACnet/IP and MS/TP topologies — addressing, routing, and termination faults included.
Open lab →OT Cybersecurity Hardening
Segment a flat BAS network, lock down remote access, and respond to a simulated rogue device on the OT VLAN.
Open lab →Programming & Configuration
Controller Configuration
Configure I/O, addressing, and point setup on a simulated field controller — the checklist-driven way.
Open lab →Logic Builder + Live Controller
Build a cooling loop from logic blocks, then download it and get auto-graded. Where the TTS hardware bench is available, your program runs on a real controller over a secure tunnel and is verified over BACnet.
Open lab →Engineering & Capstone
Valve Cv & Authority
Size control valves and see how bad authority wrecks controllability long before the loop tuner is blamed.
Open lab →Damper Sizing & Characteristic
Select damper sizes and blade types against duct conditions and watch the installed characteristic change.
Open lab →Capstone Sequence Builder
Assemble a complete AHU sequence of operations from requirements — graded against G36-informed criteria.
