3.1.1 Aerator Control
The CR10X-TD automatically controls each aerator. If the dissolved oxygen
in the pond is below a user-determined value, then the aerator is switched on.
If the dissolved oxygen raises to a high set point, the aerator is switched off.
Double-click on the pond label (example Pond 1). This will pull up a slider
switch that is used to set the low and high points for each aerator in Pond 1.
The set point can be changed in two ways. To use the slider bar, point the
mouse arrow to the colored bar on the slider. While holding the left button on
the mouse slide the bar up to the value desired.
Use the edit box by highlighting the value to be changed and enter the new
value. This value will not be sent to the CR10X-TD until the ENTER key on
the PC keypad is pushed.
The aerator will switch on when the DO value is less than the value selected
with the DO ON slider. The aerator will switch off when the DO value is equal
to or greater than the value selected with the DO OFF slider. When changing

point the value has been sent to the CR10X-TD and the slider box can be
closed (select the X in the upper right corner).
