It looks like Type 4 expects fewer parameters than what you are 
specifying, which probably also explains why the setpoint and/or boiling 
point are not what you think they are.
If you are not using IISiBat, please check your component configuration 
very carefully, you probably have a typo in your parameters.
If you are using IISiBat, please send your project file to your 
distributor so they can identify the cause of the problem.

No, there is no maximum number of Type 4 units in a simulation.

Kind regards,
