Pulse

Like the M.O. Flo and Wave features, the Pulse feature is designed for water features requiring flow rates of
varying intensity. As with the Wave feature, the Pulse feature setting includes parameters for minimum and
maximum pump speeds, and period, however these pararmeters function differently than in the Wave feature.
The Pulse feature randomly selects a pump speed between the minimum and maximum values you specify,
and directs IntelliFlo to run at that speed for the span of time you enter for the "Period" parameter. At the
end of that time period, the Pulse feature randomly selects another pump speed between the maximum and
minimum values you specified and directs IntelliFlo to run at the new speed for the span of time entered in
the "Period" parameter. Like the Wave feature, the Pulse feature must be linked to any of Features 1-9, and
operates only in conjunction with those features.
Example: You have decided to use the Pulse feature to operate the laminar jets described in the Wave
feature example above. In the Wave setting, you enter a maximum pump speed of 2400
Rotations Per Minute (RPM), a minimum pump speed of 1000 RPM, and a period of three
seconds (:03), and you link the Wave Feature to Feature 3. IntelliFlo will randomly select a
pump speed between 2400 RPM and 1000 RPM, and run the pump at that speed for three
seconds. At the end of the three-second period, IntelliFlo will randomly select another pump
speed between the mimimum and maximum speed of 2400 RPM and 1000 RPM, and run the
pump at this new speed for three seconds. IntelliFlo will select new random pump speeds and
run the pump at the new speed every three seconds for the duration of Feature 3.
