Variable Speed pump control issue

Turbo DaveTurbo Dave Posts: 40Member
Hi all, I have been having great difficulty controlling a Grundfos 32-100 w/ Geni Module with a Resol DeltaSol BX Plus solar controller. This is my first use of both products and also my first experience with 0-10VDC. My goal is to control the pump start/stop and speed via the solar controller. I have contacted both vendor technical support departments, but received inadequate response. I have just sent another email to both they will be receiving Monday morning, but I am leaving the state where this job is located in 48 hours and MUST have this operating as designed by EOD Monday. Rather than describe the wiring I have done, I'd like to start clean. I have attached the I & O instructions for both. Thanks very much, Dave

    Geni

    The manual attached is for a relay module. Do you have a manual for the Geni?

    0-10 VDC is usually just 2 wires or 2 wire and a ground. The voltage varies from 2-10 volts DC. The solar controller would be putting out the signal and the Geni module would receive it and ramp the circ up and down accordingly.

    We would need the manual to be more helpful.

    The solar company has just provided detailed wiring instructions. I am all set. Thanks.
