Module 1
What Is a BMS?
What a Building Management System is, what it monitors and controls, and how it relates to the mechanical and electrical services in a building.
You will be able to
- Explain what a Building Management System is
- Identify the main building services typically connected to a BMS
- Distinguish monitoring from control
- Understand the relationship between the BMS and mechanical and electrical services
- Explain why pre-commissioning matters
Lesson notes in the online area →Module 2
BMS Architecture
How supervisors, networks, control panels, controllers, I/O modules, field devices and plant fit together, and how information and commands move through the system.
You will be able to
- Identify the main components that make up a BMS
- Explain the basic function of each component
- Follow information and control commands through the BMS
- Tell hardwired devices from networked devices
- Understand where the pre-commissioning engineer's work sits
Lesson notes in the online area →Module 3
Understanding BMS I/O
Digital and analogue inputs and outputs, universal I/O, common signal types, command versus status, and the physical device behind every BMS point.
You will be able to
- Identify DI, DO, AI, AO and UI/UIO points
- Recognise thermistor, 0–10 V and 4–20 mA signals
- Distinguish command from status
- Relate each BMS point to the physical device it represents
- Recognise common point-to-point issues
Lesson notes in the online area →Module 4
Inside a BMS Panel
Controllers, I/O modules, power supplies, terminals, relays, contactors, protection, Hand/Off/Auto, HMIs and wiring, and how each I/O type is routed through the panel.
You will be able to
- Identify the main components inside a BMS control panel
- Understand panel supplies, terminals and relay contacts (NO/NC/COM)
- Tell internal wiring from field wiring
- Follow DI, DO, AI and AO circuits through the panel
- Recognise common panel and termination issues
Lesson notes in the online area →Module 5
Reading BMS Drawings
Using real control-panel drawing sets as a practical tool: legends, the panel/field demarcation line, terminal and relay references, cross-references and revisions.
You will be able to
- Navigate a BMS panel drawing set and its legend
- Recognise the panel/field demarcation line
- Follow terminal, relay-pole and page cross-references
- Trace inputs from the field into the BMS and outputs back out
- Compare the drawing against the physical installation
Lesson notes in the online area →Module 6
BMS Electrical Principles
The electrical knowledge needed to prove BMS circuits: safety and safe isolation, AC/DC, voltage, continuity, contacts, 24 V supplies, commons and references, 0–10 V, 4–20 mA and thermistors.
You will be able to
- Apply electrical safety and safe-isolation principles
- Measure voltage between the right two points
- Understand commons, references and floating 24 V supplies
- Measure 0–10 V, 4–20 mA and thermistor circuits correctly
- Use a structured, measurement-led fault-finding approach
