By entering the correct access code, it’s also possible to access the service level of the controller. In
addition to the numeric display, there are 4 additional LED’s which show the status of Alarm, Defrosting,
Service, and Cooling.
To access the different parameters of the controller for the local display interface, there are three different
access levels.
Each level can be protected with an individual access code, defined by the manufacturer of the cooling
appliance. If a level is protected with an access code, this code must be entered first. If the controller is
accessed via both the CRA 162/172/200 and the Modbus at the same time, the latest modified value for a
setting will be stored as the final.
The access code can be adapted in the Service Mode structure in Tool4Cool
