Re: [TRNSYS-users] Controller 2d

[David BRADLEY <d.bradley@tess-inc.com>]

Juliane,
  Type2 is designed to be a "heating" controller, meaning that it turns on when the control value drops below a certain setpoint. In your case, you want the opposite so you can either use one of the controllers that is designed for a "cooling" application (Type108 would work) or you can make an equation that inverts the result of your Type2's output

output = 1-Type2Result

Best,
 David

Hello,

I would like to build my project the night air, which is a function of the horizontal radiation.
Here is my approach:
First In trnbuild I made at an input ventilation (I: 1 * Nachtl)
Second In studio I use the controller 2d, the controller when the radiation is 0 to go to on and if more than 0 to 0.

Have already tried all the options and do not get it back, he does it the other way.

What values ​​ should I enter into the input fields 1-6.

Thank you very much
