Operation of the Controller
General Information
The primary function of a Jockey Pump Controller is to maintain normal system
pressure which may fluctuate slightly due to small leaks in the system. The use
of this small pump will eliminate frequent starting of the main pump. The
Jockey Pump Controller automatically starts the Jockey Pump Motor when the
system pressure drops below a user configured level.
