ON-DEMAND Understanding CO₂ Controls
When a CO₂ Alarm Appears, Do You Know What the Controller Is Telling You?
Learn how experienced CO₂ professionals use controller data, alarm history, trends, and system logic to diagnose problems more effectively.
Three expert-led sessions covering Danfoss controls, Micro Thermo rack controllers, and Copeland E3 programming.

An Alarm Tells You Where to Look, Not What Part to Replace.
A compressor alarm does not automatically mean the compressor has failed.
An unstable pressure does not always mean the pressure control needs adjustment.
A sensor fault could be the sensor, its wiring, its configuration, or a problem elsewhere in the system.
CO₂ controllers collect a lot of information, but the data only helps if you understand how the controller and refrigeration system work together.
This training helps you read alarms, verify controller data, and investigate the system before changing settings or replacing components.
What You Will Learn
Use Controller Data to Make Better Diagnostic
Read Alarm Information
Understand what controller alarms are reporting and where to begin your investigation.
Navigate Controller Data
Find the inputs, outputs, settings, logs, and system information needed during diagnosis.
Understand System Logic
See how the controller uses sensors, setpoints, and programmed sequences to operate the rack.
Verify Before Making Changes
Compare controller information with actual system conditions before adjusting settings or replacing parts.
SESSION 1
Danfoss Controls and Alarm Diagnostics
With Chris Brown of Danfoss
A controller alarm is only one part of the diagnosis. You still need to understand what triggered it and how that condition affects the rest of the rack.
This session covers:
- Understanding the Danfoss pack controller
- Using Danfoss Service Tool
- Accessing controller data and alarm logs
- Identifying pressure and temperature inputs
- Understanding compressor safety alarms
- Checking controller configuration and wiring
- Connecting alarms to actual system conditions
- Diagnosing the rack as one connected system
SESSION 2
Micro Thermo CO₂ Rack Controllers
With Adam Hughes of Parker Sporlan
Controller screens contain valuable information, but technicians need to know where that information is located and how to use it during troubleshooting.
This session focuses on:
- Navigating the Micro Thermo controller
- Understanding rack-control information
- Reviewing controller inputs and outputs
- Reading operating conditions and setpoints
- Using controller data during diagnosis
- Connecting controller information to system operation
- Finding useful information without changing the wrong settings
- Building a more organized troubleshooting process
SESSION 3
Copeland E3 Rack Programming
With Mike Hill of Copeland
The Copeland E3 controls multiple parts of the refrigeration system. Understanding its structure and programming helps technicians diagnose problems without making unnecessary changes.
This session focuses on:
- Navigating the Copeland E3 interface
- Understanding rack-programming structure
- Reviewing inputs, outputs, and control points
- Finding setpoints and system information
- Understanding how programmed logic controls equipment
- Using controller information during troubleshooting
- Identifying configuration and communication problems
- Making informed changes instead of guessing
Who This Is For
Built for Technicians Ready to Go Deeper Into CO₂ Controls
Refrigeration technicians currently working around CO₂ equipment
Technicians moving into controller-based diagnostics
Service managers training their teams
Technicians working with Danfoss, Micro Thermo, or Copeland E3 controls
Anyone who wants to better understand alarms, system logic, and controller data
This is not a basic introduction to CO₂ refrigeration. It is best for technicians who already understand the fundamentals and want to improve their controls knowledge.

FAQ
frequently asked questions
Is this course suitable for someone completely new to CO₂?
This course is best for technicians who already understand the basic operation of a CO₂ system and are ready to learn more about controllers, alarms, programming, and system logic.
Is the training live or on demand?
The three sessions are on demand. You can watch them through Kajabi at your own pace.
Which controller platforms are covered?
The training covers Danfoss controls, Micro Thermo CO₂ rack controllers, and Copeland E3 programming.
Will this make me a controller programmer?
No single course can replace field experience or platform-specific practice. This training will help you better understand controller navigation, alarm diagnosis, system logic, and programming concepts.
Do I need access to these controllers to take the course?
No. You can follow the training without having a controller in front of you. Access to the equipment may help you apply what you learn afterward.
Is a certificate included?
Yes. You will receive a Certificate of Completion after meeting the course requirements.
Does my purchase include the RM Hub?
Yes. Your purchase includes access to the RM Hub community, where you can connect with other refrigeration professionals and access additional resources.
