Good Day, I'm using the ATR244-23BC-T model, and I need the "if" function.
I have got 2 storage tanks for Hot water, inbetween them 2 pumps(for the stable Flow) and 2 temperature sensors PT100. The END result should be like - if A1>A2 = pumps on
If A1<A2 = pumps off.
What parameteres fits this?

Hi,
you can use the parameter number 36.[cPr1]="diff" and 55.[cPr2]="diff" using the setpoint1 and setpoint2 value equal to 0. If the process value <0 --> AI2>AI1, if the process value >0 --> AI1>AI2

Best Regards.
