Dealer territories shape who can program and service the system; confirm local dealer coverage and tool access.
Career relevance: Dealer-side programming, startup and service.
Official platform referenceTypes of building automation controls
Most commercial systems now speak BACnet, but "open" has degrees. An open protocol lets devices share data; open programming means any qualified contractor can buy the tools and licenses to change logic. Ask who can program, service and expand the system before choosing it.
Field devices
Sensors (temperature, humidity, pressure, CO2, flow), actuators, control valves, dampers, relays and current switches. They measure conditions and move equipment; everything above them depends on their accuracy.
Unitary and terminal controllers
Controllers dedicated to one piece of equipment such as a VAV box, fan coil, heat pump or rooftop unit. Often factory-mounted by the equipment manufacturer.
Programmable plant and AHU controllers
Fully programmable DDC controllers for chiller plants, boiler plants and air handlers, where custom sequences, staging and safeties live.
Supervisory controllers and network routers
Building-level devices that coordinate controllers, share schedules and setpoints, store trends and route between BACnet MS/TP, BACnet/IP and other networks.
Operator front end (BMS/BAS software)
The server and browser interface operators use for graphics, alarms, schedules, trends and reports across one building or a portfolio.
Integration frameworks
Open platforms such as Niagara that connect equipment and controllers from different manufacturers using BACnet, Modbus, LonWorks, MQTT and other drivers.
Equipment-integrated controls
Manufacturer systems built around their own chillers, rooftop units and VRF, such as Trane Tracer or Carrier i-Vu. Strong on their own equipment, with open protocols for the rest.
Analytics and fault detection
Software layers that run fault detection and diagnostics (FDD), energy dashboards and measurement and verification on BAS data, often cloud-hosted.
Related building systems
Lighting controls, metering, access control and fire alarm interfaces that a BAS may monitor or share data with. Life-safety systems keep their own listed controls.
