## Description

KoolCode is a compact offline tool for technicians and engineers to quickly look up alarm, error, status and parameter codes for Danfoss ADAP-KOOL® refrigeration controllers with three-digit displays. Designed for service technicians, in-store staff, and refrigeration engineers, the extension provides on-the-spot translations and descriptions so you don’t need to carry manuals or a laptop.

KoolCode offers three easy lookup methods — quick code translation without knowing the controller type, hierarchical controller selection, and automatic controller identification via QR-code scan. The app supports English, French, Spanish, and German, speeds up diagnostics, and improves service productivity. For support use the in-app feedback or email coolapp@danfoss.com.
