8.2. The function of registering the minimum and maximum temperatures.
The SMT regulator has the function of recording in its internal memory the values
of maximum and minimum temperatures that occur throughout the regulator's
operating cycle. This function makes it possible to check whether the milk is stored under
the correct temperature conditions.
When the device is switched on, after the end of the programmed delay (parameter
AA
–
see
9. TABLE OF SETTINGS
), the temperature values are recorded to the regulator's
memory. The programmable delay time of enabling this function allows for pre-cooling
of the milk after the start of cooling and thus not taking into account the maximum
temperature when the device is started. This time should be selected by the user for the
type of tank and the actual operating conditions of the device.
At any time, the user can read the maximum
and minimum temperaturę
values presently
available. The following figure illustrates reading:
ATTENTION
1. In the absence of entries of maximum and minimum temperatures in the regulator's
memory, the symbol --- is displayed.
2. Power supply loss causes the regulator's memory to be cleared.
At any time, you can manually delete the current maximum and minimum values.
