Set up a Chart’nX water dashboard: name, presence and total meter

In the Chart’nX water generator, fill in the dashboard name, the presence source overlaid on consumption and the Total meter, measured over KNX or Modbus. Meters per zone or per use are then set up in the water groups.

Intended for administrators and installers.

Before you start

• The water dashboard is open from Chart’nX, then Configure, as described in the Emergy’nX entry point. Its name and the project have been checked.
• New dashboard creates an energy dashboard. If no water dashboard is available, or if you need to create one without a corresponding command, contact support.
• The units and the KNX addresses or Modbus configurations of your meters are known.

The water form includes the General, Overlays, Main meters, Sub-meters with the groups, Weather, Basins and Display order sections.

Name the dashboard and declare presence

1. In General, fill in Dashboard name. This name is required. Fictitious example: “Water — workshop building”.
2. To overlay presence, click + Add source in Overlays, then choose Presence / absence. It serves the whole dashboard. If you don’t use an overlay, leave the section empty.
3. In its card, choose the Protocol. For KNX, fill in the signal’s Group address in three-level format, for example 1/2/3 as a fictitious value: first level from 0 to 31, second from 0 to 7, third from 0 to 255. For Modbus, select its Modbus Configuration.
4. Check High / low state: on the ▲ row, labeled Present, choose 1 or 0 according to the value that actually means “presence” for this signal. The value offered initially is 1; the other value corresponds to Absent.

An address outside this format makes the source incomplete: correct the entry. On an existing dashboard, a presence address already configured appears as a Presence / absence source. The temperature sources and how the chips work are detailed in Overlay temperature or presence.

Set up the total meter

1. In Main meters, locate Total meter. Turn on its switch if you have a total measurement; otherwise, turn it off and set up the water groups. Disabling keeps the fields for a reactivation and has no effect on the physical meter.
2. In the active card, fill in Meter name and choose Protocol: KNX or Modbus.
3. Choose Index for a cumulative reading, or Not indexed if the value already represents the period or the instant.
4. For KNX, fill in Group address or select the correct suggestion. For Modbus, select Modbus Configuration; if the entry is missing, see the Modbus catalog.
5. In Meter unit of measurement, choose the unit of the value received: Liter (L), Kiloliter (kL) or Cubic meter (m³).
6. Check Custom Factor, a non-zero number initially set to 1. It corrects the metering ratio, for example 10 units per pulse; unit conversion goes through Meter unit of measurement. Set them according to the measurement provided, not to get a visually plausible curve.
7. To show presence on this meter, click + Add overlay in its Overlays section, then choose Presence / absence under Band. The cross on the chip removes this overlay.

Keep an old address

Under a KNX address, + Add historical address adds a Historical row for an old address of this same measurement, with its own unit and factor. Each added row must be filled in; its cross removes it from the form. For carrying history over between meters or for overlapping data, have the rules clarified by support before confirming.

Check the result

Save the dashboard. If a KNX monitoring window is offered, handle the necessary assignments. Then open the dashboard over a period in which you expect data: check the total meter curve and any presence band.

Troubleshooting

• An overlay chip shows a warning, with the Source incomplete tooltip: complete the address or the labels of the source in Overlays.
• For a blocking field or a missing measurement, follow the water dashboard troubleshooting.

If the problem persists, contact support@can-nx.com, specifying Chart’nX, the dashboard and your water monitoring need.
