  • Page 18 Hot water set temperature (T -HW set) This parameter can be used for adjusting the T -HW set temperature which is to be reached at the HW fl ow sensor S2. The controller then determines the pump speed of the primary pump such that the tem- perature at the HW fl ow sensor on the secondary side continuously keeps the required set tempera- ture T-HW set.
  • Page 19 Maximum limitation for exceedance of the hot water set temperature (T -HW set) This function can be used for preventing draw-off water temperatures that massively exceed the hot water set temperature ( scald protection). Note: The switch-on condition for the maximum limitation will only become valid if the hot water fl ow temperature is >= 60°C.

    3.3.3 Afterheating The Afterheating function can be used to reheat the upper store zone through a heat source, if necessary. It works independently from the hot water heating and can be activated by the user. When the function has been activated, the corre- sponding relay and the afterheating sensor have to be allocated.

  • Page 25: Disinfection

    3.3.4 Disinfection This function helps to prevent the spread of Legionella in DHW and circulation pipes on the secondary side of the heat exchanger. When the thermal disinfection function is active, the speed of the primary pump is controlled such that the adjustable temperature T -disinf set is reached.
