The two graphs illustrate an exemplary heating process with a setpoint of 27 degrees Celsius.
The upper graph describes the outdoor and indoor temperature of the model building and compares them to the setpoint.
Initially, the temperature inside the house was cooled down, resulting in the outdoor temperature (light blue curve) being higher than the indoor temperature (orange curve).
It is evident that when increasing the setpoint, the indoor temperature rises faster than the outdoor temperature.
Additionally, it can be observed that the slope of the curve decreases as the setpoint is approached to prevent exceeding the desired temperature.
The process was interrupted by opening the window, which lowered the setpoint to 24 degrees Celsius in this example.
Since the outdoor thermometer is mounted very close to the model building on the assembly plate due to limited space, the values for indoor and outdoor temperature are similar.
The outdoor temperature also increases as the setpoint is raised.
