Hi all, I wonder if someone can help me with my new Inkbird ITC-100VH temperature controller, which I am using to control the temperature in a small toaster oven. This seems to be a PI controller, as there I can't see a "D" setting in the instruction manual. There is a setting for "hysteresis...

If you have time, would you be able to check if your Sestos is able to do a control period less than 8? (Especially less than 3).

Yes, the red 'Out' light on the front of the Sestos came on and stayed on for quite a few seconds while the temperature soared about 30ºC above the setpoint. This was way longer than the control period. When I checked the PID settings, I had been auto tuned to 9999! This is clearly a nonsense...

Hi aquenne, Thanks for the reply. I'm familiar with PID controllers (I'm a robotic engineer and have created many PID controllers myself). I know what the Sestos is supposed to do. My problem is that it doesn't seem to be doing what I expect, and the terrible manual doesn't help. Have you...

oops, there was a typo in the previous post. Those numbers should have been Ctl Period 40 = 40s 20 = 20s 10 = 10s 8 = 8s 6 = 8s 4 = 8s 3 = 8s 2 = 70s 1 = 70s 0 = 70s

After a bit more experimentation, I am pretty sure there is a bug in the Sestos for low control periods. I tried several Ctl values, and recorded the following periods: Ctl Period 40 = 40s 20 = 20s 10 = 10s 8 = 8s 6 = 6s 4 = 4s 3 = 3s 2 = 2s 1 = 1s 0 = 0s Has anyone else had any...

I recently bought a Sestos D1S PID temperature controller, but I am finding it very difficult to get it to work as expected. I have poured over the manual, and even read the Auber manual to no avail. I think my main problem is that the Control period seems to be much longer than I expect...
