Re: [TRNSYS-users] about control strategy a pump

[Jeff Thornton <thornton@tess-inc.com>]

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.
