Programming XR-40CX or XR-60CX Dixell Electronic Controller

Reprinted with permission from Dixell.

The Dixell XR-40CX (High Temperature) and XR-60CX (Medium and Low Temperature) are fully configurable electronic refrigeration controllers. These controls are used on PRO3 Side Mount units. All parameter values are reprogrammable and are stored in the non-volatile memory.

The controller uses two levels of programming that can be accessed through the keypad. The first level is the user level. It gives access to six settings — temperature differential, defrost cycle intervals, defrost termination temperature, draining time, defrost fan delay and fan stop temperature.

The second level is the service level. It allows access to all other parameters. It is recommended that changes in this level be made only by a qualified technician.
