I have installed two Noma non-programmable thermostats in my bedroom. On controls the heat and the other controls the AC. My question is, why are the displayed temperatures different on each thermostat? They are literally 2 inches apart and the indicated temp on one is 1.2 degrees higher than on the other one. Is there a calibration that I can do or is this an acceptable difference?

The thermometer on most of those thermostats are very cheaply made and are just a by-metal coil if it is analog and a strip if digital. So I don't think you could complain about that small of a difference. Just learn to live with it.
