ConfusedThermostat

Do you think that the HVAC Guy knew that this was not the optimal location for this thermostat? If we could only get everyone in our industries to do the right thing! Right Lee?

It is a return and yes, I too believe that the problem is the cold air in the wall cavity that the T-stat is mounted to. This is a kneewall. I've heard some say that a T-stat in proximity to a return = bad. Seems to me that as you pointed out, the problem is with outdoor air migration into any cavity on which the stat may be mounted.

Help us understand a little more about what's implied by this photo.

Are we looking at a supply grill with cold air coming up the plenum behind the tstat, or are we looking at a return with some sort of cold air leakage into the return?  Judging by the warm grille surface, I'm assuming it's a return.  If so, isn't the problem more about the entry of cold air into the wall cavity (and influencing the tstat) than it is about the tstat location per se?

Either way, tstat surface seems to be at a similar temp as the rest of the room surfaces, but of course quite cold on/in the wall it's mounted to.  What's do we know about the resulting temperature where its sensor is?
