Good Day, 

I recently discovered that two ACRD units with two different PID settings, first unit P - 7.64, I - 2.81 & D - 0.

The second unit has P- 4.17, I - 2.3 & D - 1.62.

Both units has the latest firmware APP - 3.7.4 & AOS 3.9.0, 

Can anyone explain why and which should the units be using? both units were purchased at the same time.

Hello. The PID's should be set to the settings below. Set the first unit to the correct settings. They should not be changed from the factory settings.

Thank you

P = 4.17

I = 2.3

D = 1.62

So that different PID setting is incorrect? Would the unit modify the PID settings to match the environment it is operating in? Because as far I can tell those settings where never touched since it was bought

Hello Terrence. The PID settings will not auto change. The only way to change them is though the front screen or webcard.

Thank you
