Compressor electronics (CoreSense) are nothing new to the industry and Copeland has been adding them to compressors for over 20 years. Over the last decade, the advancement has been amazing from diagnostics and protection to remote communication.

As a technician, there are a few things that you need to understand when you see them in the field.

How do they work?
