Help?

Check the setting of 0-19, the factory default is '0' which only allows
control from the keypad or the comm port, try setting 0-19 to '1' which
should give control from the keypad or external terminals such as FWD.

That was it! Thank you. I think I'm going to get a better switch though,
I want something I can lock-out if needs be. 3 works as well as 1. I
just have to remember on 1 that I don't want to put it in keypad mode and
then press run if I want it to run from the pressure switch. PU light off
and it works exactly as I was hoping to. Turn the switch on an it starts.
Leave it on and when the contacts open at 120psi, it shuts off. Drop it
to 90psi and it starts up. Turn the switch off and it stays off. However
it looks like I might want to see if I can set it up with a larger range.
I'm only supposed to let it start 6 times an hour and while my draw might
be high, it is intermittent. And it looks like my unloaders are starter
types, not continuous run types. At least they didn't kick in before
190psi when I let it run up high.

Thanks again! That really helped!
