Refill Band Control

Configure Refill Band Control in HPzenAi Smart. Uses separate start and stop points to reduce pump toggling.

What it does

Start low, stop high, and avoid frequent pump toggles.

Uses separate start and stop points to reduce pump toggling. Use this automation when the selected field devices should work together without repeated manual setup.

Automation Details

Recommended use

Tanks where frequent starts and stops shorten pump life.

Device Inputs

Level Sensors, Motor Controllers, Gateways

Output Behavior

Run filling until the upper stop point is reached.

Safety Note

Keep a wide enough band between start and stop levels to avoid rapid cycling.

Test Method

Commissioning Checks

• Confirm the pump starts and stops at the expected tank levels.
• Verify the pump starts only at the low point and stays on until the high point.
• Confirm the saved card shows the correct workflow, devices, schedule, and enabled state.
• Review the event history after testing so the action is recorded as expected.
• Keep safety-critical workflows active all day unless the site needs a specific time window.

Troubleshooting

• If the Save button is disabled, complete every required trigger, condition, action, and timing field.
• If the workflow does not run, confirm the devices are online and the active time allows it to run now.
• If the action does not complete, check whether the target device is already in that state or cannot accept commands.
• If notification behavior is missing, confirm phone notification permission and recent device data.
