[TRNSYS-users] Type 99 / 109 and units

[David BRADLEY]

Be very careful!!! You cannot change units using the pulldown menu in 
/any/ component's inputs tab!!! A component's output values are passed 
directly to the appropriate component input values without any 
modification regardless of what units you have selected in the inputs or 
outputs tab. Those pulldown menus are only at the interface level; when 
the Studio writes the deck file, it writes everything in the base units 
of the proforma. Note that it is safe to change the units of parameters 
(and unconnected inputs) again because they will be converted to base 
units when the Studio writes the deck.

We do not recommend using Type109. Type109's functionality was moved to 
Type99 (for the "user-defined" data file mode) and to Type15 (for the 
standard TRY file format). If you find references to Type109 in the 
documentation, please let us know so that we can refer to the proper 
component instead!
Regards,
  David
