The VSD sheet covers remote setpoint, current limit and run/stop, water temperatures and pressures, motor and VSD values, harmonic filter data and the operation, safety, cycling and warning codes.",

 "notes": [
  "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.",
  "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 EM/SSS starter sheet uses some slots for different values (for example AV 34 and AV 35), so it is a separate entry."
