Narrative:

During climb out on our way to ZZZ; the captain performed the first flight of the day ice protection test (pneumatic). Engine #2 failed the test. We contacted maintenance control. They and the captain determined it was ok to continue to ZZZ. When we arrived in ZZZ; contract maintenance was there. I did a postflt inspection of the aircraft. By this time the maintenance guy was on top of the #2 engine pylon. I completed all duties I could for the next flight and went to the terminal. When I came back; the maintenance guy was in my seat doing an engine run. After this; he signed off the logbook and we began to prepare for the flight back. During the flight back; the captain and I began to discuss what we saw on the anti-ice; and it just didn't seem right. We felt we should see an 'open' description on the anti-ice panel for engine #2. We made the decision to not enter any ice conditions in case this was not done correctly. During the descent; we got a message of 'high stage valve failed.' this message came and went a couple of times. We saw it on the panel on the descent and then a couple of times on final approach to dfw. When we arrived in dfw; we contacted maintenance and told them what we saw. They later said it looked like the maintenance guy in ZZZ wired the wrong valve; which confirmed to us that we had no anti-icing capabilities.
