Enter the runtime for the mixer valve in seconds according to the manufacturer in “manufacturer mixer valve runtime [s]”. If the value you entered was correct, then you must now click on the button “execute reference run”. Please note that you must have previously correctly set the inputs and outputs.
The field “overrun time” lets you how much longer in percent the mixer output remains switched on when completely open or closed. This guarantees that the mixer is subsequently really completely open or closed.
Since a mixer valve normally requires longer to close than to open, you can use the “multiplier mixer closed” to define how much longer the valve needs to close than open.
