Setting up weighed water
In order to use the weighed water functionality an Expansion Board must be fitted to the Hydro-
Control. If this is not available then the parameters will be greyed out.
The weighed water system is set up from the I/O setup and status page 2. Follow the next
instructions to perform the initial setup and calibrate the input from the weigh scale.
Figure 27: The weighed water setup page
With the water tank empty, copy the ‘Weigh Scale Input’ shown on the status page (in Figure
27) into the field ‘Analogue Value When Empty’.
Now set the Hydro-Control to use weighed water. To do this, go to the first System Parameters
page (shown in section 5) and set the system water mode to Weighed. Once you have done
this, the Hydro-Control will activate the ‘Water Tank Fill’ output to open the valve to fill the water
tank to the high level.
When the tank has reached the high level this is signalled back to the Hydro-Control with the
‘Water Tank Full’ input signal. Go back to the status page (in Figure 27) and copy the number
from the ‘Weigh Scale Input’ into the field ‘Analogue Value When Full’.
Now enter the ‘Weight When Full’ figure for the water tank and press the ‘Save Changes’ button.
