Lowering the buffer temperature could help with overshooting. However, this can only be found out by experimenting in the end. As long as you don’t know the cause....
The buffer circuit has a mixer before the fresh water. I would now suspect that or the loading pump.
The domestic hot water actually does not pass through a mixer. At most, that is the return flow of the circulation, which hopefully feeds back into the cold water line before the plate heat exchanger via a check valve. By the way, that would also be another idea, maybe the check valve is not tight and you are getting cold water into the hot water line through the circulation.
What kind of fresh water system is that actually (manufacturer, type)?
