The new COMFORT AUTOADAPT circulation pump, designed for the circulation of hot water in households, achieves minimal energy consumption thanks to its unique intelligent AUTOADAPT function, and the pump does not need to be set in any way, everything happens automatically. How COMFORT UP AUTOADAPT works: the AUTOADAPT control system records in its calendar the times of hot water draw-off by the consumer (the day is divided into 15-minute intervals, the calendar is continuously updated, records from the last two weeks are used). The pump starts working 15 minutes before a recorded hot water draw-off in the calendar and stops after a period not immediately followed by another record in the calendar.
