House temp set to 75. House temp actual read is 73., but a/c unit won't turn off. I must set the control to off for unit to turn off. Normal calibration was within 1 degree, before seeing "replace" displayed. I replaced batterries and started having problems.

0 I have the same issue with a different model, the PSP511LA. The a/c continues to run. The temperature is set to 85 but the room is 65 and it won't shut off unless I change the setting from "cool" to "off."
