Anyone have a Johnson A350aa-1 controller or A350A/B contorller?

I wired my up according to the specs and it's not working. I have double checked that all the wiring in the plug and socket are right, when not attached to the controller it's fine.

It could be bad unit but I'm not sure what it meant in the diagram that in the example it's wired to an External 10 VA Transformer. Does that mean I shouldn't wire it direly with a plug, ie a need a 10 volt transformer?

Thanks!

According to the product manual, that single stage controller runs on 24VAC, and switches a single relay. While the relay can switch 110VAC for use with a heating or cooling unit, the controller logic will likely be well toasted if run on 110VAC...
