Description of the freshwater system
Systems can be extended by added functions to a freshwater
system. You will find examples of possible freshwater systems
in the connection diagrams.

Thermal disinfection to prevent legionella and daily heating up of the
DHW cylinder/s
• The entire volume of hot water is heated up on a weekly basis for half
an hour to at least the temperature that has been set for thermal
disinfection.
• The entire volume of hot water is heated up on a daily basis to the
temperature that has been set for daily heat-up. This function is not

executed if the domestic hot water has already reached the
temperature within the last 12 hours as a result of the solar
contribution.
In the solar system configuration, the illustration does not show that this
function was added. "K" is added to the designation of the solar system.
Selecting the heat meter enables the yield calculation to be activated.
• Based on the measured temperatures and the flow rate, the heat
usage is calculated taking account of the glycol content in the solar
circuit.
In the solar system configuration, the illustration does not show that this
function was added. "L" is added to the designation of the solar system.

Notice: The yield calculation only provides correct values if the flow rate
measuring unit (accessory) operates at 1 pulse/litre.
Freshwater system for DHW heating ( Fig. 20, page 202)
• The freshwater station heats the potable water in combination with a
buffer cylinder according to the instantaneous water heating
principle.
• Cascading with up to four freshwater stations is possible (set via
coding switch,  chapter "Setting the coding switch")
