[TRNSYS-users] Equation

Dear Daniel,  if you are using TRNSYS 15, the problem may be in the 
placement of the equation. In TRNSYS 16 you can place equations wherever 
you want to in the input file but in TRNSYS 15 and before, you have to make 
sure that your equation only refers to variables that have already been 
defined. In TRNSYS 15 you cannot have a pair of equations such as:

AVariable = MyVariable + 400.
MyVariable = 15.

you must have them in the order:

MyVariable = 15.
AVariable = MyVariable + 400.

If you are using TRNSYS 16, it is a little harder to guess why you are 
getting the error and I would suggest contacting your distributor with the 
specifics of your input file.
Kind regards,
