SD 240V Controller Pot: 50%=0, too sensitive

Hi,

Necro post on the starting at 40% before anything happens.

I noted that many controllers on sales start at 80V only. So the range is 80 to 220V. 80/220 = 36% (circa the 40% alluded to).

Took me a while to find one that started at 0 to 220V.

Try putting a 500k 1/4w carbon resister in parallel with the pot
The value doesn't have to be exactly 500k just some were in the ball park

Thanks for all the good info Shady.
How should I attach the resistor in the controller? Which terminal to which terminal?

Here you go, sorry for the delay
Loosen the screws and slip the resister leads in with the wires going to the pot.
Try a 470k resister rated at 1watt or more.
