Install the controller configuration tool (cct) by running setup, choosing customer install with sql express, then update sql server and activate the license using a machine tag.

Request and activate a CCT license from Johnson Controls, install field controller packages, and manage release and operation modes from 10.2 to 10.7 for Metasys, Facility Explorer, and BC Pro.

Use the software manager to view and activate CCT licenses. Request licenses from Johnson Controls with your system ID and machine tag, then activate online with a product key.

Learn the three pillars of the controller configuration tool—configure, simulate, and commission—using CCT, build applications by creating points and logic, and validate through simulation and commissioning.

Create a custom CCT project in the controller configuration tool, configure system settings, test logic in the configure and simulate modes, and save with Ctrl+S or save as.

Define hardware in CCT by selecting the appropriate controller and field device, then add expansion modules and configure network settings to enable IP-based or backnet communication.

Configure network settings for BACnet and IP-based controllers by assigning physical and application addresses, dip switch settings, instance numbers, SABUS addressing, and expansion module addresses.

Define input and output points for a bms program, create exhaust fan and damper points, set statuses, commands, and network inputs to build hvac logic.

Assign input and output points to the PCA 4911 controller via define hardware, managing unassigned points with drag‑and‑drop or auto assignment.

Master the fundamentals of digital design for BMS and HVAC control. Differentiate digital and analog signals, and explore logic gates, boolean expressions, truth tables, multiplexers, and demultiplexers.

Analyze the logical modules and blocks that compose a building management system and their role in HVAC control.

Link your BMS logic by connecting network and physical controller input/output points with consistent naming, then expose ports to activate the logic and run the HVAC control.

Learn how to transfer a CAF file to a BMS controller using direct Ethernet for IP-based devices or map tool and BTCVT for backnet or supervisory configurations.

Learn to design a sequence of operation in a BMS for a chiller, isolation valve, and chilled water pump using operator inputs, ddc control, and timers.

Learn to commission Johnson Controls devices over a local area network using direct Ethernet, IP addressing, and commissioning mode to test live values and simulate commands.

Commission devices through supervisory or map tool by configuring the device, setting its BACnet network number, connecting the loop cable, and completing BACnet commissioning via the selected IP and interface.

Learn how to commission Johnson Controls devices through the BTCVT tool, including setup, adding devices, pairing with a pair code, and viewing live values in the CCT.

Install and terminate field devices for BMS by wiring sensors (temperature, humidity, pressure, air quality), actuators, valves, dampers, and smoke detectors, and calibrate mounting and termination procedures.

Demonstrates wiring and termination of a DDC panel with 220 to 24 volt transformer, main and expansion controllers, IO modules, relays, and a terminal block for field connections.

Explore input output points in a building management system, detailing binary and universal inputs, analog sensors, and digital and analog outputs such as 0-10 vdc and 4-20 ma for hvac.

Explore show-up drawings to identify BMS equipment layout, VAVs, UPS, DDCs, supervisory panels, and TCP/IP network routing, enabling efficient installation, troubleshooting, and commissioning of the BMS.

Learn how riser diagrams map the bms and hvac controller layout by floor, showing supervisory panels, BACnet and Modbus connections, and the number of devices.

Explore the sequence of operation for a constant volume dx air handling unit, detailing startup, shutdown, airflow control, temperature management, filter monitoring, and bacnet mstp-based ddc communication with the bms.

Explore BMS layouts for HVAC systems, identifying digital input and output points, pressure sensors, dampers, control panels, and integration with fire alarm and smoke evacuation systems.

Explore Johnson Controls field controllers and expansion modules across FX series, F4, and metaseries, with BACnet MSTP and IP communications, programmable PC series, and expansion options.

Learn to assign unique device addresses for mstp and bacnet networks, using dip switches for expansion modules and rotary switches for main controllers, while observing master ranges 4 to 127.

Compare SC bus and FC bus rules, including RS-485 topology, baud rates, and shield grounding. Explain SA bus connections, device limits, DIP switch addressing, repeaters, and maximum cable distances.

Explore BTCVD bluetooth wireless commissioning converter for BACnet MSTP controllers and the MAP tool gateway, now replaced by CWCVT for wireless MSTP commissioning.

Explore simulation of a caf file within a bms hvac project, testing duty and standby logic, pid control, and valve actuators before deployment.
