How to recall a value in an iterative definition with anemone?

Hi everybody!
I tried to use anemone for calculating the internal temperature of the building. I need to start the iteration with a preset value and for the next steps, I have to recall the previous value. For example, for timestep “t” I have to recall the value I calculated in timestep “t-1”.

That’s why you have the left side on the loop start:
