A6
Applicable
Models
FTQ-TA
Outline
Error is issued if the indoor unit determines that the indoor fan motor cannot rotate.
Error Decision
Conditions
Determining successive abnormalities
Checks the rotation speed at 5-second intervals using the feedback of the fan motor.
If that figure falls below 50 rpm 5 times successively, it is deemed abnormal operation.
If, during operation, the rotation command is stopped, the 5-second interval check is halted and
the counted number will be cleared.
Determining long-term abnormalities
Checks the rotation speed at 5-second intervals using the feedback of the fan motor.
Performs rotation sampling 720 times (takes approx. one hour), and if the rotation speed falls
below 50 rpm over 100 times, it is deemed abnormal operation.
When the sampling reaches 720 times, the counted number will be cleared and the 720 times
sampling restarts.
If, during this, the rotation command is stopped, the 5-second interval check is halted, but the
counted number will be kept.
When the rotation command is restarted, the checks will resume.
