ITC-1000 Wiring Question

OK- complete noob question. I wired up my ITC-1000 (Farenheit version of STC-1000 temp controller) and it seems to work fine, but when I plug my circuit tester into the heating side, I get a “Hot/Neutral Reversed” light. Does this mean that I simply reversed the hot and neutral wires from the power cord? TIA.

Got it fingered out. Had the hot and nuetral wires swapped, as suspected. D’oh! :oops:
