 "summary": "The Multistack web portal is a gateway that talks to a COMPU25 chiller master controller over RS-232 and publishes its data as BACnet IP Analog and Binary Values. The BAS can start and stop the chiller, write the upper/lower chilled water setpoints, VSP and load limit, and read system temperatures, per-compressor status, suction and leaving water temperatures, coded fault values and a 20-entry fault review. This is an older product; the manual dates from 2008.",

  "Legacy product: the manual is dated May 2008. This copy is hosted by a third party (Chipkin), not on a Multistack site.",
  "Points exist for 24 compressors; AV 1 reports how many are actually installed.",
  "Write points (AV 135-143, BV 33) are write-only; read the values back from the matching read points (AV 9-17, BV 1).",
  "The manual's text gives different instance numbers for some points (write setpoints as AV 134-142, flush time/duration as AV 153/154) than its Table 3. Table 3 is self-consistent (AV 134 is FAULT 20 COMP #, AV 153-154 are HRS @ 90-100% and MOST CURRENT FAULT) and the text has other slips, so this list follows Table 3; confirm with a device discovery.",
  "Units are not printed in the table; temperatures follow the manual's degrees F.",
  "Object names are the table's reference names; the short labels (e.g. ENT CHW SYS TEMP) are in the descriptions."
