One of the service techs found this Easter egg in the intake pipe for the furnace. Being it was a 98% efficient furnace with an S30 thermostat we could remote in to the thermostat from the shop and see that the error code was 228 which is a soft lockout and a failed pressure switch calibration which usually leads to a plugged intake or exhaust. This saved time for us and money for the customer when the service tech knew where to start. Win win situation.
