3.4.10. Returning to the factory settings.
If changes are made to the factory settings and the controller is not working properly (at any
stage of its use), first you need to resore the factory settings.
In order to do so: → enter the settings → select PP → confirm → set parameter PP=1 → confirm
→ switch off the controller supply voltage → switch on the controller supply voltage again.
After performing the above-described activities, the controller will return to the factory settings,
therefore any changes made to the settings will be deleted.
After switching on the power again, the PP parameter will automatically re-set to 0.
3.4.11. Scaling the temperature sensor.
If there is a discrepancy in the controller’s temperature meter with the reference meter, you can
adjust the indications.
In order to do so: → enter the settings → select the CU → confirm; the display will show 0.0 →
measure the milk temperature with the reference meter → the difference between the
reference meter and the controller meter should be set with the ▲ and ▼ buttons, paying
attention whether the value should be added or subtracted (minus sign) → confirm the change
by pressing the button S → exit the settings.
ATTENTION
The change of the meter scaling should be done with caution, as in some cases it is enough
to move the measurement sensor to a different location or increase the contact between
the sensor and the measured medium. Particular attention should be paid to all intermediate
measurements, e.g. when measuring milk temperature by measuring the tank wall
temperature.
ATTENTION
The controller is equipped with a function that makes it impossible to change the control
temperature set by the installer. This function is activated by setting parameter LF=1 (default
LF=0).
