.Procon.Base Modbus Register 40: Name Temperature setpoint zone 1

Technical Definition

The register name Temperature setpoint zone 1 at address 40 is used to monitor name Temperature setpoint zone 1 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 temperature_setpoint_zone_1 (Address: 40)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=40, 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 temperature_setpoint_zone_1"
  address: 40
  value_type: S_WORD
  unit_of_measurement: "°C"

💡 Engineer's Insight

Analysis: Desired Temperature for heating zone 1 (e.g., in °C or °F). The target Temperature for the first controlled area.

Troubleshooting: 0 might mean heating is off or disabled. Verify zone 1 active status, heating demand, and potential frost protection settings.
