  • Page 36: Temperature-Controlled Domestic Water Heating

    5.2 Temperature-controlled domestic water heating Task: The domestic water temperature must be maintained at a minimum of 50 °C using a heating element. The water temperature is measured using a remote sensor (e.g. order no. 9070321). The sensor is connected to a TA 4 S input and the temperature value is sent to the bus. Channel C1 receives the domestic water temperature via a threshold object and switches the heating element to relay output.

  • Page 41: Conversion Of Percentages To Hexadecimal And Decimal Values

    6.1.3 Teach-in scenes without telegrams Instead of defining scenes individually by telegram, this can be done in advance in the ETS. This merely requires setting the All channel scene statuses parameter (Scenes parameter page) to overwrite at download. Accordingly, the required status can be selected for each of the 8 possible scene numbers in a channel (= Status after download parameter).
