August 27, 2026 — Air Flow merge Temp Split (rework step 3 of 4)
Path: ?v=19
What changed
- Stepper is Air Flow · Fan Laws. No Temp Split step, no “what to calculate” dropdown.
- RA DB, SA DB, RA WB on the same 2-col grid. ΔT is the shared coil split (not a second ΔT).
- RA + SA fills ΔT (|RA−SA|). RA + ΔT fills expected SA (cooling: SA = RA − ΔT). Heating if SA > RA.
- RA WB + RA DB → RH and dew point in the live status line. Furnace rise note 35–75 °F when heating.
#tempsplit opens Air Flow.- On-page formula/hint footers removed; formulas live in Help only.
- Follow-up the same day (ship): ΔT keeps RA, leftover negative SA ignored, pad C, local preview — live grid log.
