Abstract (en)
[origin: EP0194637A2] Circuit for controlling a boiler which charges a water storage heater and which can also be connected to a central heating system containing radiators, the water storage heater having a temperature sensor which has a switching contact, and furthermore a summer/winter switch for the boiler and a temperature regulator for the heating system being provided, in which according to the invention three parallel branches (16, 17, 18) leave an operating voltage source (L), there being arranged in one the switching contact (11) of the temperature sensor (10), in the second (17) a current meter (31) for releasing the temperature regulator (7, 41, 43) for the heating system and in the third a further current meter (25), the latter responding to the switching state of the temperature sensor (11). <IMAGE>
