SYSPHS12 — The water temperature from TemperatureIncreaseConstraint and HeatingCalculationConstraint starts at 0 °C (should probably be the environment temperature 20 °C).

The water temperature from TemperatureIncreaseConstraint and HeatingCalculationConstraint starts by Modelica default at 0 °C (should probably be the environment temperature 20 °C). From HeatingCalculationConstraint:

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

It needs a realistic startup parameter and value.
