SYSPHS12 — The water temperature from TemperatureIncreaseConstraint and HeatingCalculationConstraint starts at 0 °C

The water temperature from TemperatureIncreaseConstraint and HeatingCalculationConstraint starts at 0 °C (it should probably start at the environment temperature 20 °C).

{increase=energy/(specificHeat*waterVolume)}

{tOut=max(min(100,x),0)}
{der(x)=tInc/c1}

HeatingCalculationConstraint needs an additional parameter as integration constant with a realistic initial value set via an additional value property binding in HeatingCalculation.
