KoolCode – Fast and easy way to look up status

[App] KoolCode

KoolCode  KoolCode offers you a fast and easy way to look up status, alarm, and setting codes for Danfoss electronic refrigeration controls.

KoolCode provides service technicians, refrigeration engineers, in-store technicians, and others with on-the-spot access to alarm, status, and parameter descriptions for a large range of Danfoss refrigeration controllers with a three digit display. You save time and increase productivity with the Danfoss KoolCode App for “on-the-spot” ADAP-KOOL® controller information.

Download this app to get a simple off-line tool to easily look up alarm, error, status, and parameter codes without bringing along the printed manual or laptop.

KoolCode offers three alternative ways to look up display codes:

1. Quick code translation without knowing the exact controller type
2. Hierarchical controller selection among Danfoss refrigeration controllers
3. Automatic controller identification via QR-code scan

Available in: English, French, Spanish, Russian, and German.
