For this example, to access and activate Distribution circuit 2, you first need to enter the access code as described in the Commissioning
Guide. Then navigate to "Mix valves" in Settings and press the text "Distribution circuit 2".
On page 1, set the values for minimum/maximum supply line temperature. On page 2, you can adjust the heat curve for Distribution
circuit 2. Notice that, depending on if the distribution circuit is set as a radiator or floor heating system, the "Factory reset" button will set
different values. After all the adjustments are made, go back to page 1 and press the switch at the top of the page to activate the func-
tion and also make it visible and accessible in the menu for the end user.
