What It Means
Variable-Speed Pump Not Communicating
Likely Causes
- Low-speed bus/RS-485 wiring incorrect
- Pump address/configuration not learned
- Automation controlling relay power instead of data
- Damaged communication board
Next Checks
- Verify pump has constant line power and is controlled by communication, not relay cycling
- Check data-wire polarity and connection at Omni/ProLogic low-speed bus
- Re-discover pump in configuration after wiring changes
- Cycle power to pump and automation after correcting wiring
