calc[244] and calc[252] are configuration setpoints (max supply / max hot-gas temp), not sensors #269
Description
On firmware V3.90.4 (WZSV 92K3M, brine/water inverter), two still-Unknown_Calculation indices are easily mis-decoded as sensors — they are actually static configuration setpoints, verified against the web UI (Instellingen → Temperaturen):
| index | meaning | scaling | web-UI label | example |
|---|---|---|---|---|
| 244 | max supply (flow) temperature setpoint | raw ÷ 10 → °C | "Aanvoer max." | 660 → 66.0 °C |
| 252 | max hot-gas (discharge) cut-off setpoint | raw ÷ 10 → °C | "T-HG max." | 1150 → 115.0 °C |
252 especially: it is a constant 115 °C setpoint — not a condensing pressure or live sensor, which the value/scaling can be mistaken for.
These are firmware-extended calculations (present on recent firmware, ≥~3.88); meanings may differ on other firmware generations.
Decoded while working on a Domoticz plugin for these pumps: https://github.com/Rouzax/luxtronik-domoticz-plugin-v2

For calculation 252, also note #180 and #262
