Thats the remote sensor mounted at the filter rack in front of the MAKE-UP AIR damper.

I string temp stats all the time in returns but prefer to drop it lower. Today found one dead smack against the evap coil.

See the remote sensor ? Stats downstairs taking the temp input of the sensor thats hung in front of the make up air damper.

Fan starts, make up air damper opens mixing 90 degree air with return air and the unit never shuts off. Stat reads in the mid 80s with space temp around 69.

Thazs what I was getting at.

If the stat is mounted down stairs then I don't know why they would mount the remote sensor there! That doesn't make sense. Usually see a Accu-stat mounted inside the unit.

There is a pretty specific description of "what Im getting at" above the pic in the first post.

Assumed that was enough information for a HVAC forum. My bad.

Some commercial buildings especially restaurants will use remote sensors so all of the thermostats can be mounted in one place. Usually in the managers office.

This is the bathroom RTU for an upscale restaurant in Houston,

They should be located in the space but the installers got lazy and a little stupid in their placement. I don't have a problem with installing them in the return plenum but well enough away from the make-up air inlet to prevent this exact scenario.

Looks more like "shoved in there" than mounted.......
