The GRN/BLK on the heater share a 4 wire run with 2 wires (RED/WHT) used for a valve actuator. The GRN/YELLOW wires on the pump comm share a 4 wire run with a WHITE/RED for the water temp sensor.

Because the equipment is too far from the ET panel to use the included wires, you will see some 4 and 5 wire bundles carrying multiple items, but the wires end up in the rights places. Unfortunately, the pool electrician who hooked everything up did a patchwork job and I am trying to sort it now. Again, I have tried a direct connection (without multiplexer) into J20 of both sets of wires at the same time with the same result. The first Blk/Grn/Yellow/Red wires in the center go to J20 on the ET board and next Blk/Grn/Yellow/Red wires to its right go to the SL Antenna. In my photos, the GRN/YELLOW wires on the left are the COMM for the Intelliflo VS. The ONLY items plugged into the multiplexer and then going into J20 are the Green/Yellow PUMP comm wires and the Blk/Grn/Yellow/Red wires for the SL Antenna. With all of the troubleshooting I did, I cannot imagine it is a bad board or bad wires. I am not sure if I need to wire this up differently or if anyone has a suggestion. I have even swapped out the black connectors to the boards in case it could be that, but no dice. Best I get is about 30 seconds of responsiveness from SL app and then it stops communicating. Again, as long as the pump is disconnected from comm, SL works without a hitch. I have tried different J ports on the multiplexer and checked the wires and see no crimps or cuts. Immediately, as I pull out the pump Green/Yellow connector, Screenlogic immediately responds to commands. Again, pump has good comm and Screenlogic nothing.

I also have the multiplexer as well (520789), so I hooked the pump up to one of the Green/Yellow connectors and Screenlogic Antenna to one of the Green/Yellow/Black/Red connectors and connected the multiplexer to J20. I am using the intellibrite on/off command (Aux 1 and Aux 2) to troubleshoot responsiveness between Screenlogic app and the ET board. When I remove the Green/Yellow wires for the pump, the pump, of course, goes into NO COMM under status, but Screenlogic commands are received from the app without delay. Whenever the Green/Yellow comm cables from the Intelliflo VS are plugged into J20 at the same time as the Green/Yellow comm cables (plus Black/Red) from the Screenlogic antenna, Screenlogic will not respond to commands, but pump shows good connection to the system. I have the pool and spa and spillway working just fine, but a problem has arisen. I have recently taken my system back to the beginning and erased the EEPROM and started reconnecting everything from scratch. I have the ET8 system (pool/spa combo) with the Intelliflo VS and Screenlogic2. I have been reviewing the forum and cannot find a solution to my problem in other threads.
