[TRNSYS-users] Problem with type 14b forcing function

Type 14 is exactly the Type that you want for your simulation.  Two 
separate users replied to your earlier request (I believe it was you and 
apologize if it wasn't) on how to use Type 14 - did you follow their 
suggestions?  I would also suggest that you review the SDHW example 
provided with TRNSYS.  Remember, Type 14 needs to have every point 
specified to make up your forcing function.  For example, if you had a 
daily function where you are drawing 100 kg/h from 7am to 9am and 200 
kg/h 7 pm to 9 pm each day, the parameters would be:

0,0
7,0
7,100
9,100
9,0
19,0
19,200
21,200
21,0
24,0
