[TRNSYS-users] Radiation problem with Type 942

[David BRADLEY]

Jakob,
   Looking at the source code for Type942, it would appear that the sky 
temperature is part of the top loss correlation used by the component. 
Can you please send your project to your distributor so that they can 
have a look and see if they can determine the cause of the problem?
Kind regards,
  David
