Thermostat sensor like a A19 mounted so the supply air effects its operation.
I have come across this a few times and I don't like it. For a while I thought someone did not know the direction of air flow in a reach-in but in a walk in there is no way.
Is there any reason to do this?
My thinking is you want the air in the box to be in the safe zone so control that the air entering the evaporator or if you want the coil temp directly
what do you think
