This can cause the fan to ramp up and down and may not be required in some
applications (it can actually cause noise discomfort). The product is factory set on a
jumper switch combination where the constant flow mode is not activated.
When the external switch is turned on, the fan is boosted. After the external switch is
turned off, the fan continues to run at boost speed for a settable period of time, then it
returns to selected trickle speed. The over-run timer function is activated only if the
external switch has been on for at least 60 seconds.
