Yeah.. screwed if you don't want to do 220, but why not? You can always get 220, it just a matter of running it to the controller. I suspicion you will be able to use the contacter to switch 110V without a problem, so the device you are controlling could be 110V. Like many of the controllers that are 110 that can use the contacters for 220V. If it's rated at 110 and you use 220 you are in trouble, if it's rated at 220 and you use 110V, you're fine for a contacter. Like a bridge rated at 10 tons, 5 is fine but the reverse isn't OK.
Edit: That's a bunch for a controller. You can get a PID 110V Controller for $37.99
