[TRNSYS-users] Type 56 - Chiller only in summer

[David Bradley]

Gizmoog,
   I would recommend using either a Type14 forcing function in combination 
with a controller component (Type2 for example) to turn on and off the 
chiller. Type2 would operate the chiller based only on Type56 zone 
temperatures regardless of the time of year. Type14 would be set up to 
disable the controller during the winter months so that the chiller remains 
off. To do this, your Type14 forcing function might have a value of 1 
during the summer and 0 during the winter and you might multiply the value 
of the forcing function by the control signal coming from Type2. If you 
have access to the TESS Applications Library, there is a heating and 
cooling season component that will do the same basic thing in a bit more 
comprehensible way.
Kind regards,
  David
