  • Publication number: 20180347856
    Abstract: In a heating heat-source apparatus having input circuits configured to receive pieces of mutually independent heating demand information, an abnormality related to an operation for setting one input circuit among the input circuits to a use state is detected and reported. Input circuits receive heating demand information. An operation part receives an operation for setting one input circuit of the input circuits to a use state. A CPU receives heating demand information transmitted from the input circuit in the use state while receiving specified information for specifying the input circuit in the use state from the operation part. Each piece of heating demand information is voltage information having a predetermined voltage range. The CPU reports an abnormality related to an operation for setting when voltage information transmitted from the input circuit in the use state deviate from a voltage range specified in the specified information.

  • Publication number: 20180314275
    Abstract: The disclosure provides a heating and hot water supply apparatus which includes a heating circulation path configured to circulate a heated heating medium with a heating terminal, and a bypass path branched from the heating circulation path for causing the heating medium to flow therethrough without passing through the heating terminal. A hot water supply heat exchanger is disposed in the bypass path. A division ratio of the heating medium from the heating circulation path to the bypass path is controlled by a distribution valve. The division ratio is increased from a first value to a second value when a reservation preheat control is started during the heating operation according to a start reservation time of hot water supply operation reserved by a timer, and set to a third value greater than the second value during a simultaneous operation of the hot water supply and the heating operation.

  • Patent number: 9204007
    Abstract: An image reading device includes a conveying unit, reading unit, and a control unit. The conveying unit conveys successive two sheets along a conveying path such that a gap is formed between the successive two sheets. The reading unit reads a sheet conveyed at a reading position in the conveying path. The reading unit has a light source and light-receiving unit. The control unit controls the light source to emit light at a first light intensity for a sheet that has reached the reading position. The light-receiving unit receives light reflected by the sheet present at the reading position. The control unit further controls the light source to emit a light at a second light intensity lower than the first light intensity during a period of time from when the reading unit has been read the preceding sheet to when the reading unit begins reading the subsequent sheet.
