Possible Causes
Incorrect communication wiring, Wrong pump address, Disabled external control mode, Faulty automation relay or port
How to Fix / Troubleshooting
Safety: Turn off power to automation and pump before working on low-voltage wiring.
- Verify control mode: On the Zodiac pump interface, ensure it is set to accept external or RS-485 control as required by your automation system.
- Check wiring: Confirm that communication wires are connected to the correct terminals and polarity at both pump and automation panel.
- Address settings: Make sure the pump's address/ID matches the configuration in the automation software.
- Test relay output: If using relay control, verify that the automation relay closes and supplies power to the pump when commanded.
If the pump still ignores automation, a technician may need to test or replace the automation or pump control boards.
