 "summary": "With PRO functionality, CoolAutomation gateways publish service data from Fujitsu AJ*NLAH outdoor units over BACnet: type, capacity, operation, mode, defrost and oil recovery, compressor, valve, heater and fan states, thermistor temperatures, high and low pressure, compressor drive frequency, inverter temperature, DC voltage and current, fan frequency and EEV positions, plus a second (constant speed) compressor, low-noise, forced-off and capacity-save states (46 objects).

  "Object names are the guide's short names; descriptions are the guide's object descriptions with the bracketed unit moved to units.",
  "Table printed on page 314 of the guide (section 3.2.9.2).",
  "Md (Mode) states are from the guide's Fujitsu PRO Enumerated Parameters table.",
  "The guide lists no error-code object for Fujitsu outdoor units.",
  "The guide prints this exact table twice (pages 313 and 314) under two model headings; both are merged here.",
  "Those headings also name AJYuLALH, AJHuLALH, AJHuLATH, AJYuLATH, AJQLALH, AJYLALH, AJHLALH, AJHLATH and AJYLATH. The page-314 heading repeats the page-313 model list in the same order without the 'u', so the 'u' codes are taken as the same models; the guide lists those models under other tables as well (one is a 45-object version without Cmp2C, which moves every instance from 298 up by one). They are left out of applies_to; check the instances with a discovery if you have one of them."
