Warm water temperature fluctuations protecting component for warm water preparation system, has valve attached to sensor to achieve temperature outside increased legionella growth region and to heat water circuit to kill legionella
The component has a motor regulating valve (1) with an emergency regulating function for controlling a differential pressure-overflow controller (2). The valve is attached to a differential pressure sensor (3) for hot water sided regulating of drinking warm water temperature such that a circulation temperature outside the region of the increased legionella growth and heating a warm water circuit to 70 degrees for killing the legionella, are achieved by parallel switching of a solenoid valve (5) and a thermostat valve (4) under all loading conditions.
