The summer and winter times have always sucked (I live in Phoenix, AZ) because my bedroom in every house I lived in was always too hot or too cold while the system ran or before it would kick on because the temp was very different from the thermostat location. It was always so extreme, never comfy at the peaks of the seasons.

I installed this sensor in the room but not by the vent so it gets ambient temp, and found there is an average of 2-7 degrees difference from the main unit in the hallway to my room (about 12 feet) and that's with the units off. With them on I'm sure it can go all the way up to 12-15. I knew it was bad but not that bad!

Now the system temp is based off my room and not the hallway and life is beautiful when laying in bed. The temps from main unit to sensor are more even now too. I sleep better and I'm more lazy :D

Lastly, the main Robert Shaw thermostat is highly accurate and my system runs about 1/4 less than before using the +2 degree difference setting so summer and winter bills are lookin good too. Definitely buying one of these for the living room for the other thermostat now!

This remote sensor worked without a single problem. I even installed it using the existing thermostat wire instead of the recommended twisted pair, but it still worked without a problem.

Sensor placed in child's room because location of thermostat is drafty. Provides accurate readings to the main thermostat which controls the temp perfectly.
