The present invention relates to a method for controlling a steam generating system (10) for a domestic steam cooking oven (40). A steam generator (26) and an inlet valve (16) are controlled by a regulating thermal switch (30) and a limiting thermal switch (32). The regulating thermal switch (30) and the limiting thermal switch (32) respond to a temperature within and/or at the steam generator (26). A threshold value of the limiting thermal switch (32) is higher than a threshold value (Ts) of the regulating thermal switch (30). The steam generator (26) is deactivated and the inlet valve (16) is activated by the regulating thermal switch (30), if the temperature (T) of the steam generator (26) exceeds the threshold value (Ts) of the regulating thermal switch (30).

A hydronic system having a set of inputs, a plurality of boilers, and a controller. Each input representing sensor for a respective heat emitter of a set of heat emitters. Each boiler of the plurality of boilers is configured to receive signals from a portion of the set of inputs. The controller is configured to a status and assignment of the set of inputs from the plurality of boilers and control the plurality of boilers to provide heat to the set of heat emitters.

It is provided a method for level regulation of feed water in a chamber of a steam sterilizer or in a steam generator with a chamber of a steam sterilizer connected therewith wherein the feed water is heated by means of a heating element and steam thereby is generated for the chamber. A temperature change rate of the heating element is determined and refeeding with feed water is effected in dependence on the determined temperature change rate of the heating element.
