I see you have a solution, but I though I might explain a bit.

When you ask to compare a variable being equal to a constant number you run the risk of the input temperature jumping 2 degrees, which if at the wrong time could complete bypass your if condition. So its always better to use < or <= ( > or >=) for comparison.
