An external control unit to be connected between a power source and an electrically driven pump to act as a smart switch to convert a 'dumb' pump into a smart pump. The control system of this invention comprises a microcontroller-operated switch, located between the power source and the pump, or other fluid flow control device to be operated by electricity, and which can be programmed to record usage data of, e.g., hot water, by the household; it sets up the operating times in accordance with such usage. A temperature sensor is connected to the microcontroller to sense a temperature change, in a hot water system is turned on, by measuring an increase in temperature to indicate flow through the hot water pipe, and to record such data. This will determine, in the context of a hot water system, when the pump should be activated to bring up hot water.
