+      Der ASKOHEAT+ muss über Modbus TCP erreichbar sein (Port 502).
+      Über das Webinterface sicherstellen, dass "Load Setpoint" im Input Setting aktiviert ist.
+
+      **Wichtig:** Im Loadpoint `mincurrent` und `maxcurrent` passend zum Gerät setzen,
+      sowie `phases: 1` für einphasigen Betrieb konfigurieren.
+      Beispiel AHIR-BI-plus-1.75: `mincurrent: 1.1`, `maxcurrent: 7.6` (bei 230V, 1 Phase).

+      The ASKOHEAT+ must be reachable via Modbus TCP (port 502).
+      Ensure "Load Setpoint" is enabled in Input Settings via the web interface.
+
+      **Important:** In the loadpoint configuration, set `mincurrent` and `maxcurrent` to match
+      your device, and configure `phases: 1` for single-phase operation.
+      Example AHIR-BI-plus-1.75: `mincurrent: 1.1`, `maxcurrent: 7.6` (at 230V, 1 phase).
