There are 4 temp displays, built in and A, B, C. When all are next to one another, sitting under a ceiling fan, they do not agree! A is always 1 degree low. Using a more accurate thermometer, they all seem to vary +- .5 degree.
This is good enough for most applications.
i have a few of these installed in my house and some with the aculink internet units too in friends homes. they work great. i even have one in my freezer and it connects to the display on kitchen table.
Overall the remote sensors seem to be accurate, however the base station temp sensor reads about 4*-5* higher than my analog test thermometer which has always proved to be accurate.
These thermometers were easy just to stick around the house, left one inside and another in the garage and outside. So far so good
