Summary​

Carrier L/min from VFD-102 cubic curve (default) or FT-102 pulse (CFG_CARRIER_FLOW_USE_FT102). Active recipe mL/gal × carrier GPM → CMD_MP101/102/103_STROKE_WORD (0–1000 ↔ 0.0–100.0 % DDC stroke). Barista ppm deltas offset per-pump rates. When RCP_DELTA_CYCLES_REMAINING = 0, STAT_DOSE_TRIM_SCALE nudges ±5 % from CT-103 vs multiplexed target. CALC_TDSDEV_ABS feeds alarms.st.

Open items​

  • Wire CMD_MP*_STROKE_WORD to Grundfos external AO / pulse module at commissioning
  • Bench-tune SP_FT102_PULSES_PER_L and VFD-102 cubic coefficients
  • Multiplex RCP_*_TDS_TOL in alarms.st (dosing already multiplexes target)
