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:<br>
<br>
okChiller = AND(GT(TIME,3000),LT(TIME,5000))<br>
<br>
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.<br>
