Abstract (en)
[origin: EP0351716A2] Control of a circulation water heater, with a heat exchanger which is fed from a burner, of a branch having radiators and of a branch having a domestic water conditioner, which can both be connected to the heat exchanger via a priority reversing valve, the priority reversing valve having a rest position defined by means of a restoring force and being provided with temperature set-value indicators for the setting of a heating and domestic water temperature. The rest position of the priority reversing valve (10) is variable and is switched according to whether reheating of the domestic water conditioner (24) is necessary or not, and, as temperature set value for the heating water, either the set value (HZ/39) alone or the higher of the two set values (HZ/39) and (WST/40) is selected according to the rest position of the priority reversing valve. <IMAGE>
