FIELD: tool-making industry, possible use for controlling heat and thermal protection in electric water-heating boilers.
SUBSTANCE: to achieve the effect, heat is regulated and power is provided to electric resistances. In case of abnormal conditions of operation, thermal protection is realized. The electronic device receives information from one or more temperature sensors, performs disclosed heat regulating and thermal protection procedures and decides whether to continue the heat regulation process or to activate the thermal protection procedure. Logical circuit of hardware performs function of safety system, which controls correctness of operations. Device allows the user to manually return heat regulation procedure to initial stage, if the anomaly exists no more, within limits of maximal number of attempts to return to initial stage.
EFFECT: expanded functional capabilities.
