[TRNSYS-users] Type 108

[David BRADLEY]

Safwan,
  You will need to define an equation that has a value of 1 during the 
time of year when it is okay for the chiller to run and a 0 at other 
times. The equation might be:

okChiller = AND(GT(TIME,3000),LT(TIME,5000))

   The result of the equation is a 1 whenever the hour of the year is 
between 3000 and 5000. You will obviously have to adjust the times to 
your cooling season. You then multiply the Type108 output by the result 
of the equation before passing it to the chiller.
regards,
  David
