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.
