Niagara AX- Need a Pressure Temperature Conversion block
Does anyone have refrigerant pressure temperature logic blocks or something they can share with me? I need to control exv's from superheat directly in the jace. I was trying to play around with writing something in the program editor but my skill level is not up to par with line by line code.

Can you just use a PID those work well in kit control. Or a reset??
-
Yea I am going to use a pid but I need the chart to know what the superheat is. I would need 50 reset blocks to try to make this so I'd rather write a custom module

Any suction pressure transducers?? Suction line temp?? This could all help. R-22?? 410??

Shoot me an email and I will send it to you. It took me forever to find the right equation for this and then when I did I had trouble getting it in the program object and functioning correctly. I have to give the final credit to Ron aka Codewriter for getting it completed for me. You can set the input to PSIG,PSIA, or KPA.

yes i have suction pressure transducers and suction line temp. This is r134, but i can take the r-22 table and edit all the values to change it to 134.

I would appreciate a copy, thank you.

Me too, I would appreciate a copy of this program object. Thank you!
