Scaling PID - Fahrenheit to Celsius

[Charlie H]

Hi All,

On the HM config page is says "Changing units does not scale the PID parameters, which should be adjusted manually."

Im assuming all the settings posted on the forum are Fahrenheit based and im in the UK so use Celsius. Is there any easy way to scale the PID settings to take this into account?

Thanks

Yup the PIDs are multiplied times the temperature so all you'd need to do to scale them is multiply them by 9 / 5 = 1.8 to get them in Celsius.
