Set / reset circuit with timer

[tennung]

Hi
Im looking for a simple script.

Input 1 - KNX 0/2/5
Input 2 - KNX 0/2/6
Input 3 - KNX 0/2/7 (same as output)
Output - KNX 0/2/7 (same as input 3)

If input 1 sends 1 to the bus it will set the output to 1 and start a timer for 2 hours. After the timer ends the output is set to 0. A new input will restart the timer.
If input 2 sends 1 to the bus it will stop the timer.
If input 3 sends 0 to the bus it will stop the timer.

Can someone point me in the right direction?
