  "Access: 'C' marks objects the list shows as writeable; others are read-only. The doc says room operating mode and the room setpoint are normally commanded at priority 15, and a value held at priority 5 means equipment protection is active.",
  "A proprietary network-port object (type 264) in the device section is left out.",
  "The temperature control section lists PrSpC twice (AV 36 and AV 45), one per cooling control variant (room temperature control or cascade control).",
  "The doc lists two product types (DXR1.E10PL-112/US and -113/US) and two object sets (HvacFnct31 and HvacFnct33) but does not say which product or box type uses which set."
