  "Every YorkTalk 3 E-Link sheet uses the same slot skeleton (P03 = AV 1 and so on); only the slots this chiller populates are listed, and slots marked not available on every program version are left out.",
  "Object names are the E-Link names printed on the sheet; the sheet also gives LON, N2 and Modbus addresses, not reproduced here.",
  "Access follows the sheet's Modbus function note: the remote slots AV 1-4 and BV 1-4 accept writes; the rest are read-only.",
  "Multistate states are shown as printed (from 0); this sheet does not say whether the BACnet value adds 1, so confirm by discovery (read the state text).",
  "The four tabs share the slot map; solid-state starter objects only apply to SSS units, and a few slots are used only on one model."
