LM und Daikin RTD-W - Modbus

[mkoermer]

I changed the Datatype to 9 for holding registers 1 and 2, but what I transfer to Modbus with KNX is not changed when I run the RTU read test - it remains at 32767.

Code:

{
  "product_code": "RT",
  "manufacturer": "Realtime",
  "name": "RTD-W Control",
  "product_range": "Realtime Modbus",
  "description": "Realtime Modbus RT ",
  "mapping": [
    {
      "name": "Sollwert Wasservorlauf Heizen",
      "address": 1,
      "bus_datatype": 9,
      "datatype": "int16",
      "type": "register",
      "units": "Grad",
      "value_multiplier": "0.01"
    },
    {
      "name": "Sollwert Wasservorlauf Kuehlen",
      "address": 2,
      "bus_datatype": 9,
      "datatype": "int16",
      "type": "register",
      "units": "Grad",
      "value_multiplier": "0.01"
    },
    {
      "name": "Sensoreingang Heizen ein",
      "address": 10001,
      "bus_datatype": 7,
      "datatype": "int16",
      "type": "register",
      "units": "ein/aus"
     }
  ]
}

I send z. B. 2150 and 32767 remains.

Any idea why that is? or am I wrong here?
