Allows IntelliFlo Variable Speed Pump to automatically detect if pump if is primed for startup.

The pump will speed up to 1800 RPM and pause for three (3) seconds - if there is enough
water in the basket, the pump will go out of priming mode and run the commanded speed.
The priming speed can be set between 3450 RPM and 2350 RPM. If the pump is on an
equipment pad that is close to the water level, it will not need to run at 3450 RPM to successfully
prime. The setting can be lowered to prevent running at a higher speed than necessary.
Day to day factors (i.e. local ambient pressure, water/air temperatures, amount of water
retained from last system run) can effect priming performance. Because of the frequently
changing nature of these factors the priming speed should be set high enough to accommodate
environmental and mechanical changes to ensure that the pump can successfully prime.
and evaluation of priming performance.
The maximum priming time can be set from 1 - 30 minutes. This setting is the amount of time
with water and restart the pump.
Priming range can be set from 1-10. The smaller the range, the more water the pump has
to be moving to detect that it is primed. At larger ranges, the pump will detect that it is fully
primed while moving less water. If the range is set too high, then the pump may exit Priming
mode before it has fully primed. The range will automatically adjust with the priming set
Priming delay can be set from 1 second to 10 minutes.
If the pump does not have enough water after the automatic priming mode, the pump will
increase to the Maximum Speed (under "Pump Settings" on page 8) and run for 20 seconds
(or for the time set).
You may need to increase the priming delay to allow the system to stabilize before the pump
starts running speeds. If pump continues to show a priming error, increasing the priming delay
time might correct this issue.
