<p>Vajije,</p>
<p>It's a little difficult to understand from your e-mail what you are trying to do with the differential controller. Can you provide a schematic of your system and maybe a diagram of the controls you wish to implement? That will help the users here better answer your question.</p>

<div dir="ltr">Hi all,
<div>I have simulated a solar absorption chiller, I should run it for different thermal storage inlet temperatures for example with inlet temperature of 103 C. then I want the outlet temperature of thermal storage doesn't above the inlet temperature. I have defined a differential controller but it doesn't effect on outlet temperature, I changed upper and lower dead band temperature different times but the outlet temperature didn't change.</div>
<div>if someone can help me please tell me why it doesn't work? </div>
</div>
