## Revisions

- May 12, 2020, by Michael Wetter:
  Changed assignment of `m1_flow_small` and `m2_flow_small` to `final`. These quantities are not used in this model and models that extend from it. Hence there is no need for the user to change the value.
- January 18, 2019, by Jianjun Hu:
  Limited the media choice to moist air only. See #1050.
- August 18, 2014, by Michael Wetter:
  Removed parameter `forceErrorControlOnFlow` as it was not used.
- July 20, 2010 by Michael Wetter:
  Migrated model to Modelica 3.1 and integrated it into the Buildings library.
- January 4, 2006, by Michael Wetter:
  Implemented first version.
