[PID - Heater and PWM output - Doesn't stabilize the temperature after autotune.]

Hi,

I implemented default PID. After 3 cycles of autotune the PID can't control the temperature.

I followed help:

And Video:

Function that I am using.

Setup:

[How to force analog I/O (input) in Unitronics?]

I have Unitronics HMI and I/O modules at home but not the actual machine (it wouldn't fit in my kitchen).I would still like to edit and test the software.  I can't force the analog I/O and test the software. I can tell that the alarms for pressures and levels are working :).
How can one force the analog I/O?
