The critical part was getting the correct power wires wired to the 120 and COM and C. That is the important part. If done incorrectly, it can cause a spark and a circuit breaker popping, or worse. So be proud that you did that correctly!



With a relay output to the heater (or outlet strip), you either connect the black wire to the N.O. or N.C. contact. You have a 50/50 chance of being right depending on the mode of the controller. If one doesn't work, try the other. There is no danger if you choose the wrong one.
