Start-Up and Operation
Apply power to the controller. A steady green light indicates that the
SubDrive300 has power but the pump is not running. The green
light will fl ash continuously when the pump is running.
Leaky Systems
Leaky water systems might keep the controller running due to the accurate
pressure sensing capability of the pressure sensor. Continuous running
or starts and stops do not hurt the controller, pump or motor. However,
to reduce the on-time of the controller/pump/motor, a “Bump-Mode”
procedure is installed. During low fl ow (or leaky) conditions this feature
periodically increases the speed of the pump several PSI above the set
point and shuts off the pump. This adds some time to bleed off before the
system starts up again.
NOTE: Conventional private water systems intermittently fi ll a pressure
tank as commanded by a standard pressure switch (e.g. 30 - 50 psi). The
SubDrive300 maintains a constant pressure at the pressure sensor up to the
maximum capability of the motor and pump.
Although the pressure is constant at the pressure sensor, pressure drops
may be noticeable in other areas of the home when additional taps are
opened. This is due to restrictions in the plumbing and will be more
pronounced the farther the taps are from the pressure sensor. This would
be true of any system, and if observed, should not be interpreted as a
failure in the performance of the SubDrive300.
