Indoor fan motor protection
When the air-conditioner is operating and the indoor fan motor is turned ON, if the indoor fan motor has operated at 300 rpm or
under for more than 30 seconds, the unit enters first in the stop mode and then stops the entire system.
Timer light illuminates simultaneously and the run light flashing 6 times at each 8-second.
(4)
Three-minute forced operation
When the compressor begins operating the thermal operation is not effective for 3 minutes, so operation continues as is in the
operation mode. (After 3 minutes has passed the thermal operation is effective.)
However, stopping the compressor via a stop signal or protection control has priority.
(5)
Abnormality of outdoor unit
When the indoor heat exchanger temperature does not fall to 25
°
C or below for 40 minutes after 5 minutes have elapsed since the
compressor operation start, the abnormality stop occurs. (The timer light flashes 2 times.)
(6)
Compressor overheat protection
If the discharge pipe temperature (sensed by Th6) exceeds 115
°
C, the compressor stops. If the temperature is 95ºC or lower after a 3-
minute delay, it starts again, but if this function is reactivated again within 60 minutes, it results in an abnormal stop.
(Run light : ON, Timer light : 5 time flash)
