[. . . ] According to its intended use · in good condition · With due regard to safety and risk of danger. [. . . ] A) As a mixing valve for hot water supply systems and heating systems: The highly sensitive thermal element located in the outlet of the valve controls a plug which regulates the flow proportions of cold and hot water in relation to the mixed hot water setting selected. Soft seatings are fitted to both hot and cold water inlets. they provide: · A positive hot inlet shutoff if the cold water supply is interrupted, provided that the hot water inlet temperature is at least 10 K higher than that of the mixed water setting. ⷠThe cold water supply is cut off if the hot water supply is interrupted. B) As a diverter valve on central heating systems: For this application flow through the valve is in the reverse direction compared with its use as a hot water mixing valve. The inlet water passes around the sensing element and regulates the control piston so that for temperatures above the set value the water is returned to the heating circuit and for temperatures lower than the set value the water is diverted to the boiler. A protective cap is supplied with the valve to lock the mixed temperature setting. 0 bar pressure diffe-27 l/min rential across valve approximately Control accuracy <±4K Fit a return flow-retarder unit where the hot water supply system includes a circulation circuit · Observe the flow direction arrow when fitting a KB191 return flow-retarder unit · To prevent the growth of legionella, DVGW-W551 and W552 specify that the water volume in the pipework between the mixer valve and the furthest takeoff point should not exceed 3 litres.
