 1. The first thing you need to do is to fit the curve (***N*** coefficient). If your home has low heat loss, then start with 0.5. Otherwise start at 0.7. When the temperature inside the house stops changing, increase or decrease the coefficient value in increments of 0.1 to select the optimal curve.<br>
 Please note that passive heating (sun) will affect the house temperature during curve fitting. This process is not fast and will take you 1-2 days.
