 Filter clogging prevention (Reverse operation cycle time) (J189)
PID control is canceled and reverse rotation operation is performed with the reverse rotation
operation frequency (J193) in accordance with the reverse operation cycle time (J189). After
reverse rotation operation is continued during the reverse rotation operation time (J194),
normal rotation operation (PID control) is restored. While this function is operating, the
detection processing regarding input selection "J188 =2/3" is disabled. When reverse rotation
operation is being performed with input selection "J188 =2/3" made active, this function is
canceled and disabled until the next cycle time.
