How to Write Your First Program in Johnson Controls CCT | VAV Controller Tutorial
If you’ve ever wanted to learn how to program a Johnson Controls VAV controller using CCT (Controller Configuration Tool), this guide is for you. Whether you’re just getting started in building automation systems (BAS) or want to strengthen your Johnson Controls programming skills, this step-by-step tutorial walks you through the essentials of writing, configuring, and downloading your first control program.
🔧 What You’ll Learn
In this tutorial, you’ll discover how to create a working VAV (Variable Air Volume) control application using Johnson Controls CCT software.
Here’s what we’ll cover:
- How to set up a new CCT project and select your VAV controller model
- How to configure input and output points
- Building control logic using CCT’s graphical programming tools
- Downloading and testing your program on a Metasys CVM03050 controller
This walkthrough is perfect for technicians, engineers, and students who want to understand how CCT programming works in real-world BAS applications.
💡 Why CCT Matters in Building Automation
Johnson Controls’ Controller Configuration Tool (CCT) is one of the most widely used software platforms in the BAS industry. It allows engineers and technicians to create and deploy control strategies for managing airflow, temperature, and energy efficiency across entire buildings.
Mastering CCT programming gives you a competitive edge in the HVAC and automation fields. By learning how to program your first VAV controller, you build a strong foundation that leads to more advanced projects — like programming air handling units (AHUs), fan coil units, or lab air valves.
⚙️ Tools and Equipment Used
To follow along with this tutorial, you’ll need:
- Johnson Controls CCT Software
- Metasys CVM03050 Controller
- USB Programming Cable
- 24V Power Supply
- Basic Sensors (optional for testing)
These are standard tools used by BAS professionals for configuring and testing control systems in the field.
🚀 Take Your BAS Skills to the Next Level
Once you’ve completed your first CCT program, continue experimenting! Try adding custom control logic, tuning PID loops, or integrating your controller into a Metasys supervisory system.
As you practice, you’ll gain the confidence to design, deploy, and troubleshoot control systems that improve building performance and energy efficiency.
