In the Intellicenter Quick Reference Guide, it states the following:
IntelliFlo VS Settings: Pump Type, Name, Address (1-16), Min. Speed (450 RPM), Max. Speed (3450 RPM), Step Size (10-250 RPM), Prime Time (0-5 min.), and Prime Speed (450-3450 RPM). Speed Circuits: Assign the speeds to the circuits you wish to use. Tap Speed Circuits and tap Add Circuits to assign a new AUX circuit. To change the pump speed of a listed circuits, tap the AUX name to change the assigned RPM setting. Tap Return to save the setting and return to the previous screen. Affiliated Circuit Settings: Circuit: The assign circuit to control the pump speed. Speed (RPM): Assign pump speed from 450 to 3450 for the selected circuit. Pump Status: Shows the current power usage in Watts, speed, in revolutions per minute (RPM) while the pump is operating. Tap Return to return to the previous screen. Also see: Tap Status on the Home screen to display the current pump status and error condition.
IntelliFlo VSF Settings: Pump Type, Name, Address (1-16), Min. Speed (450 RPM), Max. Speed (3450 RPM), Min. Flow (20 GPM), Max. Flow (140 GPM), Step Size (10-250 RPM), and Step Size (1-10 GPM). Speed Circuits: Assign the speeds to the circuits you wish to use. Tap Speed Circuits and tap Add Circuits to assign a new AUX circuit. To change the pump speed, tap the AUX name to change the assigned RPM setting. Tap Return to save the setting and return to the previous screen. Affiliated Circuit Settings: Circuit: The assign circuit to control the pump speed. Flow (GPM): Assign pump flow rate from 20-140 for the selected circuit. Speed (RPM): Assign pump speed from 450 to 3450 for the selected circuit. Pump Status: Shows the current power usage in Watts, flow rate in gallons per minute (GPM) or revolutions per minute (RPM) while the pump is operating. Tap Return to return to the previous screen.
IntelliFlo VF Settings: Pump Type, Pump Name, Pump Address (1-16), Min. Flow (15 GPM), Max. Flow (134 GPM), and Step Size (1-10 GPM). Speed Circuits: Assign the speeds to the circuits you wish to use. Tap Speed Circuits and tap Add Circuits to assign a new AUX circuit. To change the pump speed of a listed circuits, tap the AUX name to change the assigned RPM setting. Tap Return to save the setting and return to the previous screen
So it looks like the prime time feature is only available on the VS pump configuration. Which is why I've never seen this. I have the VSF pump. I could change the configuration to VS, which is how my PB actually had it set up, but not sure what that might do. I don't use any flow settings so I wouldn't necessarily lose any functionality.
