[TRNSYS-users] Type 94, maximum power

[David BRADLEY]

David,

   I am not sure which version of Trnsys you are using. However, Type94 
was found to have some problems like the one you describe that were 
addressed with the release of Trnsys18 and Type103 (a replacement for 
Type94).

kind regards,

  David
