In fact, the electricity costs of operating in AUTOADAPT mode requires a mere 1-2 $ per year. Compared to conventional pumps that run continuously, this equals a cost reduction of up to 96%. Moreover, heat energy savings amount to as much as 48%. The AUTOADAPT principle The principle of the AUTOADAPT function is really very simple.
