Variable Speed pump control issue
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
