What the agent does
- Identify model and revision from the serial; retrieve the E-417 diagnostic tree for that revision
- Read the photo: connector corrosion on proportional valve Y3
- Order checks: safety isolation first, then alarm history, then Y3 connector and coil resistance per manual §7.4
- Propose likely parts from the catalogue with supersession check
What you get back
Ordered checklist with manual page per step, safety steps first, parts candidates with current part numbers, and a work-order summary draft.
