SAFETY AND USE
- Educational reference only. AI can make mistakes. Follow site procedures, safety requirements and manufacturer instructions.
- Lock out and tag out before opening a panel or touching rotating parts. Never bypass a smoke,
  freeze or high-static safety. Live voltage measurements only by trained, qualified personnel with
  proper PPE (NFPA 70E). Typical values vary: the nameplate and manufacturer data govern.
- Part numbers are never printed; each map says "site to fill in".
- Virtual Operator (VO) is read-only: it reads your system and never changes a setpoint or command on its own.
- Please call your preferred electrical or mechanical contractor if needed.

FREE DIGITAL UPDATES
This is a digital product, not a printed book, so you get every correction and new revision free.
When a map is corrected or revised, the updated files replace these on your order: re-download them
from the link in your receipt e-mail, or sign in at app.lemonsqueezy.com/my-orders with the e-mail
you bought with. We e-mail buyers when an update is ready. Each page shows its revision and date
("Rev. 1.0 (2026-10-19)") in the footer; the library version is at the bottom of this file. New
maps added to this edition are included too.
