The following points should be noted:
The Busy signal on the Hydro-Control V has been renamed to Admix. The functionality is the
same as the Hydro-Control V apart from the addition of ‘Admix Enable %’.
Recipe gain for AUTO Mode is no longer supported. The PID parameters should be set
conservatively to compensate for smaller batches where moisture will rise faster. A separate
recipe with local PID parameters can also be used if faster batch times are required.
There is no longer a calibration mode as the calibration can be more simply performed using a
recent batch in the Mix Log as a “template” to set up the calibration points and the target for the
recipe.
The AUTO Mode water control loop parameters will need to be commissioned. This is because
the setup of the AUTO Mode control loop has been simplified making it much easier to tune
correctly to achieve more efficient performance. For a starting point when upgrading a system,
divide the Proportional Gain parameter used in the Hydro-Control V by 10 and set the Integral
and Derivative Gain parameters to zero.
