Control Mode Options

OFF – The OFF control mode will stroke the pump at a user defined rate.
From 0-125 strokes per minute or per hour. Click here for programming
pH Control – The pH control mode will allow the pump to stroke proportionately
based on high and low pH set points. This will allow the pump to stroke faster
as the pH reading moves away from the desired control level and slower as it
gets closer to it. Click here for programming
pH/Flow – The pH/Flow control mode uses a multiply/divide feature as a part of
the programming that allows for an incoming dry contact pulse (such as from a
water meter) to dictate how many times the pump will actually stroke.
For example, setting the "Multiply" to 5 means that a single incoming pulse
from the water meter indicates to the pump that it needs to multiply that
by 5, which would cause the pump to stroke 5 times per dry contact pulse that it
receives.
If the pump is was set in "Divide" that signal by 5, then it would require receiving 5
dry contact pulses from the water meter before the pump would stroke once.
