Duco Modbus templates
All 3 available Duco templates for ModbusCloud.
Monitor DucoBox demand-controlled ventilation, energy, focus and silent variants, via Modbus.
Duco is a Belgian manufacturer of demand-controlled ventilation and indoor-air-quality systems for residential and commercial buildings. The 3 Duco Modbus templates in our library cover the DucoBox Energy, DucoBox Focus, and DucoBox Silent Connect, each a heat-recovery ventilation unit with multi-zone control via valves and room sensors.
With ModbusCloud and these Duco Modbus templates you read ventilation status, airflow rates, CO2 and relative humidity levels, temperatures, remaining time, and valve positions across multiple nodes. Writable registers control ventilation positions per zone (whole-box or per individual valve), target temperatures, and ventilation-mode timing. The Silent Connect template exposes the ventilation-position setpoint for residential installations; Energy and Focus add multi-node valve control for larger commercial buildings.
All 3 Duco templates are free to browse. Import one into your ModbusCloud portal to orchestrate whole-house or whole-building demand-controlled ventilation with automated setpoint management.
