2. Did it work properly for 4 months after replacing and all of a sudden give this message?

3.What is model on thermostat?

Expert:  airheatman replied 9 months ago.

Ok either the controller has gone out again or your control board is failing.

From Manual:24. During the equipment learning process, “UNIT IS FACTORY PROGRAMMED AND CANNOT BE USED WITH DIFFERENT MODEL FAN COIL” appears on the User Interface screen. What does this mean? This message appears when the blower motor coil cannot communicate with the fan coil control board. Inspect the blower wiring harness for loose or faulty connections. If this does not resolve the problem, the fan coil control board or blower motor module may be defective.
