  "A raw value of 0xFFFF means 'not available'. Many registers apply only to particular booster types or need a sensor; see the support columns in the manual.",
  "Pump blocks repeat every 10 registers: pump 1 at 00401, pump 2 at 00411 ... pump 6 at 00451. Pump power is in 10 W steps. Pilot and backup pump blocks (00461, 00471) and Pump-x energy for pilot/backup were left out.",
  "Left out: tank-filling limits (00111-00114, 00215-00219), DDD remote-sensor setpoints and fieldbus sensor block (00119-00128, 00146-00156), manual pump speeds (00136-00143), PI tuning registers 00144/00145 and 00231/00232 (offset/scaling not clear enough), FeedbackSensorMin/Max (00221/00222, no scaling given), analog input values/units (00224-00230, 00376-00382, scaling depends on an enum), flow measurements 1-3 and remote/differential pressures not listed above, and the DDD logged sensor data. Alarm simulation registers were also omitted.",
  "AlarmCode 00205 lists booster-system codes; when the alarm comes from an individual pump the pump's own Grundfos code is reported (see the E-pump code list)."
