  "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.",

  "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.",
  "Status code objects (MV) use the code tables in the sheet; it notes that BACnet multistate values are the printed code + 1. Printed states are shown from 0.",
  "The standard-starter tab is a subset of the SSS tab; objects only on the SSS tab apply to solid-state starters. The VSD tab is a separate entry."
