[TRNSYS-users] Trnsed parameters

[David Bradley]

Kent,
  TRNSYS goes once through your input file to make sure that you have 
all the equations that you reference. It checks for three types of 
keywords, CONSTANTS, EQUATIONS, and the END statement. TRNSYS actually 
only looks at the first three letters of a variable name and if it sees 
a variable that starts with END or CON or EQU, it can't tell whether 
that is a variable or a keyword. When the Studio writes equations, it 
sometimes assigns variables that start with those three letters. The 
best thing to do is to take the TRNSED file and run through it with 
Edit: Replace and change all of the equations that start with END, CON, 
or EQU to something else (EEND, CCON, or EEQU for example).
Best,
 David
