.Procon.Base Modbus Register 44: Name flow Temperature setpoint zone 1

Technical Definition

The register name flow Temperature setpoint zone 1 at address 44 is used to monitor name flow 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 flow_temperature_setpoint_zone_1 (Address: 44)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=44, 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 flow_temperature_setpoint_zone_1"
  address: 44
  value_type: S_WORD
  unit_of_measurement: "°C"

💡 Engineer's Insight

Analysis: Desired supply Temperature for zone 1's heating circuit (e.g., in °C or °F). Target Temperature for fluid circulating in zone 1.

Troubleshooting: 0 indicates no heating demand or circulation for zone 1. Check zone 1 setpoint, system load, and pump operation.
