RC params for the heating system

[srtenvex]

Not really an "issue" per se - just wanted some clarification based on the tutorials.

In the tutorial docs, it is stated that Ch and Rih is precalculated on the data. How is the calculation done? Based on the data in demo_data.csv how is the time constant for the Ch and Rih calculated?

Not calculating these values, and setting the parameters to vary yields some very skewed results.
