.Procon.Base Modbus Register 48: Name legionella Temperature setpoint

Technical Definition

The register name legionella Temperature setpoint at address 48 is used to monitor name legionella Temperature setpoint on the .Procon.Base.

• Protocol: Modbus RTU
• Data Type: S WORD
• Unit: °C
• Access: Read Only

How to Read (Python pymodbus)

Use this code snippet to read this specific value via RS485:

from pymodbus.client.sync import ModbusSerialClient

client = ModbusSerialClient(method='rtu', port='/dev/ttyUSB0', baudrate=9600)
client.connect()

# Read name legionella_temperature_setpoint (Address: 48)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=48, count=2, unit=1)

if not result.isError():
    print(f"Raw Value: {result.registers}")
else:
    print("Error reading register")

client.close()

Integration (Home Assistant)

Paste this into your configuration.yaml:

- platform: modbus_controller
  name: "name legionella_temperature_setpoint"
  address: 48
  value_type: S_WORD
  unit_of_measurement: "°C"

💡 Engineer's Insight

Analysis: Setpoint Temperature for Legionella disinfection cycle (e.g., in °C or °F). Target Temperature for periodic high-Temperature flush.

Troubleshooting: 0 means Legionella cycle disabled or not active. Verify scheduling, system readiness, and if the cycle is enabled in configuration.
