Product review (5 stars): Review of Acurite 00611
Overall, the unit is great and easy to read and we end up checking it all the time. The daily Hi-Lo feature is also very nice.
The install instructions were not as specific as they should be. Technical support recommends using the B channel and installing the remote batteries first to keep the units in sync and to give a more accurate reading. We have the inside unit mounted to an outside wall, which may be why the inside temp reads a few degrees higher on the warm days. There is no way to calibrate the settings, but give or take a few degrees is not as important as being able to read it from across the room.
