Just a little more information. In the 206 series the Anti Ice is normally ON at an OAT of 5 deg C or less in visable moisture (some earlier modles stated 4.4 deg, but I'm not that smart).You will see an increase of aprox 50 deg on the TOT, however should you try to check the function of the anti ice at idle the change is sometimes very minimal and hard to see.
Normally with the Anti Ice on (below 5C) you will not be TOT limited as far as power requirements for a particular operation however, if you are TOT limited then you will be reducing your TOT by 50 deg or, just maybe a power check is in order!
