Frequently Asked Questions
Q: My Hydro-Control VI needs to be sent for repair. If I get a service replacement how do I transfer
all the parameters from the old to the new unit?
A: All System, Recipe and Mix Log data can be downloaded from one Hydro-Control VI onto a
USB Memory Stick and then uploaded to another unit. Therefore assuming that the damaged
unit still switches on and has a functioning RS232 or USB port, then all the data can be
transferred.

Q: How do I calibrate my controller to display real moisture?
A: To display real moisture, when calibrating a recipe enter the true moisture for the final target.
The true moisture can either be determined from a sample of the concrete at the end of the mix,
or by calculating the amount of water in the mixer using the mix design parameters. It is
important to ensure that the correct dry weight is entered into the recipe for the calibration.

Q: Does the Hydro-Control VI display water/cement ratio?
A: The final water cement ratio is displayed in the mix log. This value will only be true if the cement
weight is entered into the recipe and the recipe has been calibrated to display true moisture.
