CONFIGURATION PARAMETERS
6
The parameters are set by default in ºC and the relative values and limits are shown in the table in this unit of
measurement. In order for the controller to display the values in ºF, set P2 to 1 and after the change, disconnect the
power from the device and then reconnect it. Any previously stored blast chilling and blast freezing programs will
return to the default value each time that P2 is reset.
N.B.
-
Because some functions are managed according to the value set for some parameters, ensure these are
set correctly and consistently.
-
It is not possible to set any value beyond the minimum and maximum limits indicated in the table.
-
fter changing the parameters, it is advisable to disconnect the power from the device and then reconnect
it.
The following table gives the meaning of the configuration parameters.
