This allows the boiler to respond correctly to a hot water demand when a conventional thermostat arrangement is being used.\n\nIt provides a practical way to connect compatible external cylinder controls to the boiler while maintaining the appropriate control signal.\n\n\u003ch3\u003eCompatible Viessmann System Boilers\u003c\/h3\u003e\n\nThe Cylinder Demand Box is designed for use with selected Viessmann Vitodens 050-W, 100-W and 200-W system boilers. It can be particularly useful when adapting a system to work with a 230V cylinder thermostat rather than a Viessmann hot water cylinder sensor.\n\nAlways confirm compatibility with the specific boiler model and control arrangement before installation.\n\n\u003ch3\u003eComplete Installation Pack\u003c\/h3\u003e\n\nThe box is supplied with the essential components needed for installation, including a mounting bracket, fixings and installation instructions. This provides installers with a convenient, manufacturer-specific solution for connecting the appropriate cylinder demand controls.\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e \u003cul\u003e \u003cli\u003eViessmann Cylinder Demand Box for system boilers\u003c\/li\u003e \u003cli\u003eViessmann part number: 7574319\u003c\/li\u003e \u003cli\u003eDesigned for use with a 230V cylinder thermostat\u003c\/li\u003e \u003cli\u003eSuitable for compatible hot water controls\u003c\/li\u003e \u003cli\u003eConverts a 230V AC input into a low-voltage boiler demand signal\u003c\/li\u003e \u003cli\u003eDesigned for compatible Viessmann Vitodens system boilers\u003c\/li\u003e \u003cli\u003eSuitable for Vitodens 050-W System Boilers\u003c\/li\u003e \u003cli\u003eSuitable for Vitodens 100-W System Boilers\u003c\/li\u003e \u003cli\u003eSuitable for Vitodens 200-W System Boilers\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eWhat's Included\u003c\/h3\u003e \u003cul\u003e \u003cli\u003e1 x Cylinder Demand Box\u003c\/li\u003e \u003cli\u003e1 x Mounting Bracket\u003c\/li\u003e \u003cli\u003e1 x Fixings Pack\u003c\/li\u003e \u003cli\u003e1 x Installation Instructions\u003c\/li\u003e \u003c\/ul\u003e \u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e \u003ch4\u003eWhat is the Viessmann Cylinder Demand Box used for?\u003c\/h4\u003e\n\nThe Cylinder Demand Box is used with compatible Viessmann system boilers when a 230V cylinder thermostat and hot water controls are being used instead of the Viessmann hot water cylinder sensor.\n\n\u003ch4\u003eWhat does the Viessmann Cylinder Demand Box do?\u003c\/h4\u003e\n\nIt converts the 230V AC input from compatible cylinder controls into the low-voltage demand signal required by the boiler.
