Controller · R38 open assembly
R38 controller cabinet study shown as integration context for Core, not a released Core enclosure. The board and screen sit inside the service door. The backplate is unpopulated; wiring, power equipment, sealing and electrical qualification remain open.
Prior component/integration study. This image is not the released retrofit design, a pump model or proof of host-tank fit. Read the source revision’s specific limits.

Exterior supervision, local service and upstream power isolation for the retrofit.
Provide exterior supervision, authorized local service, installation records and upstream isolation. The protected Tank Hub owns the selected individually controlled load branches. Website or subscription availability must not disable essential local operation.
Design priorities.
- Local installation record and revision identity
- USB-C/Wi-Fi service direction
- Upstream isolation and clear loss-of-link indication
- No assumed reserve for tank pumping
Where it belongs
Building-exterior qualified enclosure, within the approved routed connection envelope.
Research is not a released product.
Earlier component and tank studies remain available with their original context. No image transfers treatment, fit or manufacturing qualification to this retrofit.

02 / Compatibility
Match the role.
Not just the connector.
Selection is checked against the actual installed configuration, not inferred from an illustration or a catalog family name.
- 01
Installed role and electrical class
Confirm against the released documentation and approved installation record before use.
- 02
Supported hardware, firmware and load combination
Confirm against the released documentation and approved installation record before use.
- 03
Independent safeguards and power/network-loss behavior
Confirm against the released documentation and approved installation record before use.
Adding this family to an inquiry does not establish compatibility.
03 / Service approach
Plan the next service call.
Isolate, identify and verify the replacement against the actual configuration. Discovery is not approval to operate; restore required protection and record recommissioning.
Replace deliberately
Follow the qualified isolation, access, containment and replacement procedure for the actual assembly.
Verify the result
Reconcile identity and calibration, restore safeguards and record the required commissioning checks.
04 / Before you order
A few useful answers.
The final selection needs qualified specifications, configuration-specific instructions and the approved site design.
Can I order this product today?
Not yet. The retrofit and component families are in development. Released configurations, prices, inventory, fulfillment and checkout are not connected. An inquiry is not a purchase or reservation.
How is compatibility confirmed?
The actual host tank, product revision, electrical or hydraulic class, installed role and qualified configuration must be reviewed. A familiar name or matching connector does not establish compatibility.
Who installs and services it?
The intended model uses qualified Subfield-approved installers and maintainers with applicable site permissions. No-entry service is a design goal, not authorization for unreviewed structural or electrical work.
Are ratings, manuals and warranty terms final?
No. Qualified procedures, exact ratings, required care and reviewed commercial terms follow product release. Development objectives are not shipping specifications.
Related functions—not a verified bundle or permission to substitute parts.
