Setting the Temperature
Set the required (maximum) domestic hot water temperature on the controller under "Para".
To ensure that scalding cannot occur at the water valve, the maximum hot water temperature must not
exceed 60 °C.
Primary side
The temperature required in the buffer tank on the primary side depends on the desired hot water tempera-
ture and the required dispensing quantity. The temperature in the buffer tank must be at least 5 K above the
required hot water temperature.
Secondary side
The possible dispensing medium flow rate [l/min] on the water valve depends on the hot water temperature
that is set in the controller and the temperature that is available in the storage tank.
The recommended maximum domestic water medium flow rate through the fresh water module is 25 l/min.
The following table shows the relationship between the storage tank temperature and the maximum dis-
pensing medium flow rate that is connected when the temperature on the valve is 45°C (e.g. single-lever
mixer). If the hot water temperature that is set on the Controller is higher than 45 °C, the dispensing medium
flow rate consists of a mixture of hot and cold water.
The transmission capacity that is specified for this is required to warm the water quantity of the dispensing
medium flow rate [l/min] from 10 °C to 45 °C.
