#2 for my controller is neutral (so that my digital display lights work). The jumper between 3 and 4 just gives available power to 4 so that when the controller closes the 4-5 circuit it will send the 110 to the contactor. There is no need to send a second 110 leg to my controller because it works off of 110 and sends 110. Make sure that your controller sends 110 instead of 220. If it does send 220 then that could be the reason that you popped your 110v coiled contactor, and you'll need one that has a 220v coil.

Edit: Now that I've reread your first post (220 volt controller) this is the case. Sorry if I mislead you.

Edit again: After thinking about it, I don't see why you can't just use one of the 110 outputs from your controller to trigger the contactor. Maybe someone else will chime in. I think Banditperformance knows a bit about electricity.
