How use Tutorial on Time Series Forecasting (for beginners)

I am following Tensorflow’s tutorial on time series forecasting I created and saved the model like in this tutorial. There are many examples in the manual for learning, but few use of it.

My question is how to use the saved model in another script? How to predict temperature e.g. “01.01.2017 00:10:00”? How to get temperature value in normal format?
Example code from tutorial: Google Colab
