This was one of our scenarios.
I suggested faulty measuring device, but faulty measurement or location suffice.
Here's what I would ask next.
Is the switch we are relocating high or low pressure (temp)?
If I have my time line correct, unit was installed in Feb. but only recently began to malfunction. That jives with a high pressure sensor (with higher EAT) but not necessarily a low pressure monitor (otherwise I would expect trouble right out of the box).
