 "summary": "A Hood Controller carries up to four hood temperature probes and one set of optics for smoke (effluent) detection. On BACnet IP each one can appear as its own virtual device behind the Intelli-Hood System Controller, with four temperature values in °F and an optics-tripped flag. Hood Controller devices are off by default and must be enabled in the configuration.",

   "Front ends that send Who-Is without routing only find the System Controller; run a network/router discovery, select the router with the Intelli-Hood DNET, then discover devices again.",
   "The DNET must be unique; another router or BBMD using 654 breaks access to the virtual devices.",
   "Hood Controllers default to 'Active on BACnet' = No, so they are missing from discovery until enabled."
