[TRNSYS-users] Help with type 15

[David BRADLEY]

Daniela,
  I am not sure I understand what you are trying to do but on a very 
general level, the two instances of Type15 will each produce outputs 
from their respective weather files throughout the entire simulation. If 
you want a component to receive data from one instance of Type15 at the 
start of the simulation and then to change so that it receives data from 
the other instance of Type15 at a later point in the simulation then you 
will need to use some equations that make the switch. For example, if 
you write the two equations:

switchTime = GT(TIME,5088)
T_ambient = T_ambient_1*(1-switchTime) + T_ambient_2*(switchTime)

the value of T_ambient will be equal to T_ambient_1 from hour 0 to hour 
5088 and then will be equal to the value of T_ambient_2 until the end of 
the simulation.

I hope this helps.
kind regards,
  David
