Possible Causes

Incorrect wiring to automation relay or RS‑485, Wrong control mode selected on pump, Automation system not configured for Waterway protocol

How to Fix / Troubleshooting

Safety: Turn off power to both pump and automation before changing wiring.

  • Verify control mode: In the Waterway pump menu, ensure it is set to external control or relay mode as required by your automation system.
  • Check wiring: Confirm that control wires from the automation panel are connected to the correct terminals on the pump (relay inputs or RS‑485).
  • Test manual override: Bypass the automation by setting the pump to standalone mode. If it works, the issue is likely in the automation wiring or programming.
  • Consult manuals: Match the communication protocol and address settings between the Waterway pump and the automation controller.
