KNV is an Austrian heat-pump brand, historically partnered with Nibe, and sells KNV-branded Greenline units as well as rebadged Nibe F-Series and S-Series heat pumps for residential and light-commercial heating. The 3 KNV Modbus templates in our library cover the KNV Greenline heat pump, the Nibe (KNV) F-Series, and the Nibe (KNV) S-Series, spanning both Modbus RTU and Modbus TCP connectivity.
With ModbusCloud and these KNV Modbus templates you read supply/return temperatures, operating hours, heat quantities, flow rates, compressor state, alarm codes, thermal and electrical energy totals, and operation modes. Writable registers control room temperature setpoints, hot water setpoints, heating curve, DHW demand, supply-flow setpoints and operation mode. Curve offsets and S-Series energy totals make the templates suitable for energy-audit and commissioning work.
All 3 KNV templates are free to browse. Import one into your ModbusCloud portal to supervise KNV-branded heat pumps alongside other heating equipment for multi-site service and single-dwelling installations.
