Flow & PressureBypassBypass
Provides minimum flow bypass for the
First sequence
flow bypass for the jet pump
Always open to prevent deadheading pump
Always be in this mode to start the jet pumpjet pump

Flow & PressurePre-fill
Second sequence
Pre fill
Provides low pressure pre-fill sequence until qsystem filled
Allows the system to start without water hammerwater hammer effects
