[TRNSYS-users] Control problem

[David BRADLEY]

Atli,
   You'll need to implement an equation that combines the results of 
your three different control signals into one. For example, if you want 
the diverter to do something if any of your three cases are true then 
you could write the equation:

yDiv = OR(OR(condition1,condition2),condition3)

yDiv would have a value of 1 if condition1, condition2, or condition3 
have a value of 1. Alternately if you want the diverter to do something 
only if all three of your conditions are true then you could write:

yDiv = AND(AND(condition1,condition2),condition3)

There are also greater than, less than, etc. functions available for 
making comparisons between cases.
Regards,
  David
