The automatic refill unit from the brand Flamco consists of an automatic assembly (Autofill) and a smart sensor with remote communication (Flexcon PA). It is an efficient solution for both households and service companies. When the system pressure drops, the unit automatically refills the system with heating medium. Since most fault reports and heating system shutdowns are caused by a lack of medium in the system and low pressure, automatic refilling eliminates trivial and often chargeable service company call-outs.

Flexcon PA is a smart unit communicating via Bluetooth with a mobile phone app. It provides timely alerts on pressure drops, the need to refill the system, reports any faults in the system, or the need for maintenance of other parts of the system. In combination with the Autofill automation, the system is automatically refilled when the pressure drops, and Flexcon PA simply sends an informative message to the app.

A major advantage of the unit is dual remote communication - both with the user's app and the service company. Since the unit sends data and reports to the service company as well, it is possible to assist the user remotely without the company needing to make a visit.
