Customer reply replied 2 years ago
the head was programmed by total line and it did run for four months
HVAC Technician: airheatman, HVAC Technician replied 2 years 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.
