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.

Reheating is not considered if the cold water tem-

perature is 10 °C

* maximum medium flow rate: 25 l/min, pressure

loss of the fresh water station is 1000 mbar in this

case (higher values are possible in a limited way

hydraulically).
