[Hai-users] question about flush mount remote temp sensor

[Brad]

The following is very important with any thermostat sensor, but this becomes
vital with the flush mount type....and that is there should be absolutely no
way for un-conditioned air to get into the wall cavity behind said sensor. 
IE:Cold air in the wall cavity would have major impact on the sensor.
It's best if the wall cavity...besides no air infiltration...is also full of
insulation.

thanks Dan...I did notice that there is a small ridge just under the disc
and after looking at the drawing that came with the sensor, it appears that
the sensor needs to be installed up to the ridge with the disc slightly off
of the wall, which jives with your experience.
