PID setup

[fluidmechanics]

Hello, I am building a controller with a MYPIN TA4. I am having trouble with the initial setup so that it reads accurately. It is erratic at one moment and steady but high the next moment. The poorly translated instructions are no help. What are your hy1, hy2, pvf, p, I, d, oud, hys, ctl values. Thanks.

Correction, when all 3 outputs are on, the latent heat is causing the PV to go up. When alarms (other outputs) are off the PV goes down to 3 deg F above actual temp. Any ideas?

Did you ever get your settings right? I'm curious to see what you came up with.

Cheers!

I just figured out how to correct for the 3 degrees. Then I turn the other outputs off.
