The UI says setting Ti to zero will disable it but it doesn’t. It works with Td.
Thanks for reporting.
Looks like setting Ti to zero prevents the integral from accumulating, but did not reset it.
Already pushed a bug fix, will include it in the next release.
You can manually reset the integral or set it to any desired value by clicking ‘I’.
Edit: tried it. Actually you can only do that when Ti is not zero, to prevent divide by zero here:
Awesome thanks for the quick response.
