    Jandy Aquapure R0452500 Flow Sensor Manual


    I'm on my 3rd Jandy flow sensor in 3 years. This latest model (R0452500) has an interface module that dangles outside the power center. In addition to a Sensor Flow Indicator, there are Program A and Program B indicators. Surprisingly, the installer did not know the function of these program indicators, only suggesting I try Program B if Program A stops working. The interface module says "See manual for details", but I wasn't provided a manual. I also can't seem to find anything but an installation manual on-line (

    Does anyone know if a user manual exists? Or if not, the purpose and function of the Program A and Program B Indicators?

    On the pcb there is a cpu with a number on it. If the number is 02110A10 or 01220A15, you use program A, otherwise you use program B.

    This guide shows another way to determine the software revision.
