Modified hot water supply for hot water system, comprises a pressure difference measuring- and regulating unit which consists of a pressure switch, and has adjustable timer after the circulation pump

摘要

The hot water supply comprises a pressure difference measuring- and regulating unit (3) which consists of a pressure switch (4). An adjustable timer (5) is connected to the cross-section narrowing (8), and is arranged after the circulation pump (6) in the flow. Tapping points (9-11) are distributed after the pressure difference measuring- and regulating unit. The furthest tapping point (11) has a display and a light emitting diode(LED)/heat sensor combination (12), which is in functional working connection with the circulation pump. The electromechanical pressure difference measuring- and regulating unit may be replaced with an electronic component, and the LED/heat sensor combination may be connected to the switch relay.
