Se nedan för beskrivning av PID:en;
P value is multiplied with the error.
Loop Action = Reverse (Heating)
Error = (Setpoint=21°) – (Temp=20°) = 1°
P=10
Output = 10(PC) * 1(Error) = 10%
I is repeats pr. minute.
So if you I=1 the output will be increased to 20% (1 repeat) over a minute if the error is the same.
On a heating system I would normally start P = 1 and I = 0,75 and see how it goes. Better a bit slow than to fast.
Pressure needs to be more fast and depending on you CV values 300pa or maybe 70pa the P value needs to be low to start with maybe P = 0,2 and I = 5.
