Integrates Hargassner boiler control via Modbus TCP
Overview
This ModbusCloud template integrates Hargassner biomass boiler controllers over Modbus TCP. It reads outside temperature, boiler temperatures, flow temperatures for heating circuits HK1, HK2, and HKA, buffer tank temperatures at top, middle, and bottom, system status for boiler, buffer, and heating circuits, boiler output and fuel consumption. Writes include target temperature for boiler, target flow temperatures for the three heating circuits, and buffer tank target temperature.
Key readings
- Outside Temperature
- Boiler Temperatures
- Actual Flow Temperatures HK1/HK2/HKA
- Buffer Temperatures Top/Middle/Bottom
- Status Boiler/Buffer/HK1/HK2/HKA
