OK now I'm really confused. This is a quote from jcdillin on the BrewTroller forum in response to a question I posted about wiring the 16 port relay board.
"For your 12v solenoid it's even easier.
Your going to just take 12v and hook it to one terminal of the P/V1 relay. Then your going to connect one wire of your solenoid to that. Then your going to take your other wire for your solenoid and connect it to ground. That way when the relay is activated then the solenoid is ON. Now if you want to manually override that relay then you are going to want to use a wire like this.
http://www.oscsys.com/3-Pin-Connector-with-Leads.html and connect it to the JP1 terminal on your relay board. That terminal is designed to be attached to a 3 position switch. So meaning that when the switch is in the center then the output will be forced off. Then if you switch it one direction then the BrewTroller will have control and if you switch it the other way then the valve will be ON until you turn it off. All 16 outputs can be controlled that way. You just keep adding wires down the row."
So which is it??? The way I read this is when the relay is activated it allows 12V to run to the valve via the wire connected to the relay and it runs to ground from the wire on the valve running to ground turning the solenoid on.
