FAUN is a top-of-the-range heat meter calculator designed for professional applications in heating, cooling and combined heating and cooling systems. The device works with both ultrasonic and mechanical flow transducers, as well as paired temperature sensors, which are separate components of split heat meters – including those from other manufacturers.
Extensive configuration, communication and data archiving capabilities make FAUN ideal for use in heat distribution centres, residential and commercial buildings, and industrial facilities. Parameters can be configured either via the device’s buttons or using dedicated service software. By using the FAUN converter, you gain:

Can operate as a heat meter, a cooling meter, or a combined heat and cooling meter in a single circuit

Wide compatibility thanks to cooperation with ultrasonic and mechanical flow transducers and paired temperature sensors (including those from other manufacturers)

Clear and easy-to-read data display thanks to a large, 8-digit LCD display with intuitive symbols and units

Simple operation and configuration of the device via buttons or the dedicated FAUN Serwis software

Extensive data archiving capabilities across more than 5,000 configurable logs (minute, hourly, daily, monthly, annual, tariff, event and error logs)

Two independent tariff registers, enabling flexible energy billing

The ability to monitor leaks in the system thanks to cooperation with two flow transducers

Flexible power supply options, including several battery-powered variants and the option of an external power supply (24 VAC/DC or 230 VAC)

Extensive communication options thanks to the ability to perform two independent installation processes for communication modules without affecting the device’s verification status

Alerts for instances where measurement parameters exceed their thresholds, and the logging of events and errors

Support for multiple external devices via 4 standard pulse inputs (e.g. water meters, electricity or gas meters)
