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: 

On_Off_Pump = NotSummer * Type2ControlSignal 

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.
