 "summary": "The YMAE is the YORK by Johnson Controls modular air-to-water heat pump with inverter compressors; the four-pipe version heats and cools at the same time. Its BAS points list gives BACnet objects next to N2 and Modbus addresses: on/off and mode commands, entering and leaving water setpoints for cooling and heating, chiller-level status and temperatures, and module-level circuit values and bit-coded fault words. Module data is read one module at a time through AV 8.",

  "Writable setpoint ranges (IP units) are in the descriptions; SI ranges are in the sheet.",
  "All MV enums are printed in the points table and the sheet has no add-1 note. Multistate states with their own enum in the points table are shown as printed, from 0. BACnet multistate values start at 1, so the device may report the printed number + 1; confirm by discovery (read the state text).",
