Indoor motor warning (BP AC,
DP OF K SERIES)
HSU-18H03/R2(DB) Fault display code
The indoor motor finds no motor signal in a 10-sencond period after increasing the voltage. Running for 30 senconds
after cutting off the output voltage for the indoor motor, AC gives no motor signal but warning under new voltage for the
motor. Both he power light and running light blink twice at 1 Hz/s and then the power light, timing light and running light
blink once. The sames cycle goes on.
