.Procon.Climate Modbus Register 26: Operating Mode Raw

Technical Definition

The register Operating Mode Raw at address 26 is used to monitor operating mode raw on the .Procon.Climate.

• Protocol: Modbus RTU
• Data Type: U WORD
• Unit:
• 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 Operating Mode Raw (Address: 26)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=26, 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: "Operating Mode Raw"
  address: 26
  value_type: U_WORD
  unit_of_measurement: ""

💡 Engineer's Insight

Analysis: Raw value representing the current operating mode of the climate control system. Interpretation requires lookup table.

Troubleshooting: Device communication error, internal control failure, or invalid mode selection.
