<p>You'll need to use a forcing function and set the non-summer months to a value of 1 and the summer months to a value of 0. Then simply use an equation and multiply the control signals together:</p>
<p>On_Off_Pump = NotSummer * Type2ControlSignal</p>
<p> </p>
<p>where NotSummer is an equation connected to the Type 14 forcing function and Type2ControlSignal is an equation connected to the output of the Type 2 differential controller. Then simply connect the On_Off_Pump equation to the input control signal for the pump.</p>
