This compressor controller modulates the compressor based on an input from the OEM's system controller which measures temperature, pressure or humidity to calculate the needed compressor capacity and communicates that capacity to the compressor controller via an analog signal. The controller detects problems by monitoring the compressor, the discharge gas temperature, and power level to the compressor. This increases repair technician accuracy, reduces troubleshooting time, and reduces the frequency of "No Defect" compressor replacements.

- Fast implementation:
- no complicated system controllers are needed to enjoy the benefits of compressor modulation
- can be installed inside the outdoor unit cabinet and easily wired into the system
- easy to retrofit for contractors
- Diagnostic capability reduces downtime:
- modulates Digital compressors
- b. detects common system problems and flashes an "Alert" LED to direct repair technicians to the root cause
- c. increases repair technician accuracy, reduces troubleshooting time, and reduces the frequency of "No Defect" compressor replacements
- Compressor protection capability:
- Once a system fault is detected, the Copeland Scroll Digital compressor controller takes action to prevent compressor damage
