Max Value

Hello,

Have a temp sensor for a buffer tank that stores water and is heated with solar.
I want to know the max value of the day and that it reset on 00:00.
What i did was T059 is the weekly timer that gives pulse output.
On LWE i do see the values but it doesn't reset the max value.
When i try this in simulation it works but in real time it doesn't.
Can somebody help me?

Thank you!

Hello, I fixed the problem.
My internal clock wasn't setup...
