[TRNSYS-users] Temperature and %RH setpoint TRNBUILD

[David BRADLEY]

Gary,
   Defining your setpoint as a SCHEDULE in TRNBuild simply allows you to 
set a value that depends upon the time of day. Defining your setpoint 
using an INPUT allows you a good bit more flexibility. You could define 
your equation as follows:

Tset_heat = 24*occ + 12*(1-occ)

occ would have to be defined in another equation or perhaps a Type14 
forcing function to have a value of 1 when the building is occupied and 
a 0 when it is not occupied.

Best,
  David
