114 is a communication error in the air handler. It can be the afc board, the blower motor or both. Cycle power to the AHU by the breaker. Leave off for about 10 seconds. If error comes back you will likely, at least need an afc board.

I am experiencing the same error code on my American Standard AC and according to Public. #18-HD32D2-8, error code 126 is in the Equipment Change Alert Group and the description says "Equipment does not match value stored at startup." Then, in a footnote, it says "A device has changed since Auto Discovery (See Installer Guide *S& 0706 to reset)."

This is all Greek to me so I'm calling my AC guy. I can tell you this, however. I bought an American Standard AC brand new just two years ago and one year ago exactly, it blew up. American Standard replaced it. Now, one year later, more problems.

I question the quality of American Standard and would not be inclined to buy this brand again.

Error codes from American Standard Pub 18-HD32D2-8, which is a one-sheet document that came with my American Standard air-conditioner:

29 = not listed

129 = not listed

80 = HPCO Fault - problem is in outdoor unit - Desscription: High Pressure Monitor Fault (hard lock out, cycle power to reset)

91 = Communication Inactive Fault - problem is in air handler - Descriptions - COMM Bit Master Clock Error, COMM Heat/Cool Demand Error, Serial Motor Communication Inactive Error

91 = Communication Fault - problem is in furnace - Descriptions: Blower motor no COMM response, Inducer motor no COMM response, Loss of heat/cool demand, Loss of clock signal

91 = Communication Fault - problem is in outdoor unit - Descriptions: Loss of Heat/Cool Demand Message (COMM), Loss of Bit Master (Clock Signal)

91 = Communication Fault - Description: Comm line is dead and no bits have been received.

By the way, I do not recommend American Standard. I've had mine 14 months and it just blew up - the entire control panel blew. My advice to you - think about a different brand.

Look for the error code on the right hand side of the display above the zone section and below the actual temp displayed.... refer to:

The two wires are the control circuit from the heater your running. They go to the thermostat and close when it get below the thermo. setting and start the heater.

This is one where you will need a good control man or woman. The American Standard ASYST system is not intended for the homeowner to change out. It has a room sensor wire that others do not account for.
