Controller for circulation pump using statistical techniques, has computer that switches pump on before statistically usual tapping times to make hot water available before tap is operated

摘要

The device has a sensor (3) for detecting hot water tapping (flow monitor, temperature sensor, tap switch contacts, motion sensor on was basins, etc.) connected to a computer (7) that notes tapping events in a memory with the associated times and uses statistical methods to draw conclusions regarding consumption habits. The computer switches the pump (2) on before the usual tapping times to make hot water available before the tap is operated.
