7.5 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 max-
imum 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 dispensing 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.
