[TRNSYS-users] type 88 independant rooms ?

[David BRADLEY]

Sara,
  There is not a limitation on the number of Type88s that you can have 
in a simulation. I would recommend that if you are trying to maintain a 
particular temperature in the rooms, you use Type108 instead of Type2. 
Type2's controls are based on temperature differences, not on a specific 
temperature set point. While Type2 can be set up in order to maintain a 
specific temperature Type108 is somewhat more intuitive.
Kind regards,
  David
