Comfort Alert™
Comfort Alert diagnostics is a breakthrough innovation to help contractors troubleshoot heat pump and air-conditioning system failures. This diagnostic module monitors and analyzes data from the Copeland Scroll™ compressor so you’re able to more accurately and quickly pinpoint the root cause of the problem.

Copeland PerformanceAlert™
Copeland PerformanceAlert refrigeration diagnostics monitor compressor operation and provide advanced protection and diagnostics, making it easier to accurately diagnose and prevent refrigeration system failures.

Copeland Scroll Digital™ Compressor Controller
The Copeland Scroll Digital compressor controller is the electronics interface between the Copeland Scroll Digital compressor or the Copeland Discus Digital compressor and the system controller. This controller not only modulates Digital compressors, but it also detects common system problems and flashes an “Alert” LED to direct repair technicians to the root cause.

CoreSense™ technology
Emerson’s CoreSense technology unlocks advanced diagnostics, protection and communication in Copeland compressors. By using the compressor as a sensor, CoreSense technology gives technicians insight into the system through the compressor, providing valuable information to help diagnose problems quickly and accurately, reducing costly callbacks.

KMC FlexStat™ Controller
Emerson Climate Technologies has approved the use of the KMC FlexStat controller with Copeland Scroll Digital compressors. The FlexStat controller, compatible with 3-15 ton Copeland Scroll Digital compressors, is a networkable thermostat and controller that enables variable capacity modulation, dehumidification, and improved system performance.

The SecureStart module uses state of the art technology to provide a safe and consistent start-up for the compressor. By limiting the starting current by up to 75 percent, the SecureStart module delivers a new level of protection and start-up consistency, providing reliable system performance and longevity, while reducing nuisances caused by current variations.
Smart Contactors

Smart Contactors
Emerson SureSwitch™ relay and CoreSense™ Protection module provide critical compressor protection by guarding against the most common sources of mechanical contactor failures – such as arcing, foreign objects, pests and brown-outs.
