I'm after some help/advice.
I've installed my Aquamist 1s but I don't want to use the pressure switch, I'd prefer to control it via the MS, so to that end, I have built the output circuit for output 1 as per the manual.
![](http://www.msextra.com/manuals/MS_Extra_Hardware_Manual_files/RelayOutput.JPG)
So instead of using the supplied boot pressure switch, I intend to hook the ouptput signal from the above circuit to the ouptut from the boost switch?
What I don't understand is how the boost switch turns the pump on and off. I can't post a picture of the Aquamist 1s install diagram, but the pdf is here http://www.aquamist.co.uk/cp/system1s.zip
As I read the diagram the switch comes after the relay, and the relay is primed from switched power (as I understand it) so the boost switch is always live, but from the way it's wired it also looks like the pump is permanently powered too circumventing the boost switch??
As I'm not using the switch, can I just pull the wiring out of the connector, dump the switched live connection and plumb the output from the MS to where the switched live was on the relay? or does something have to be done with the '3rd' wire?
Also does anyone know what the outputs 'output'? is it 12v? I've not had a chance to test it as my DVM died on me. :(

I still don't get how the Boost switch works though, according to the Aquamist wiring the pump gets 12V all the time the way I read it?
