Notes (1) When the indoor unit heat exchanger temperature is in the range of B~C ºC, the speed is reduced by 8 rps at each 20 seconds. When the temperature is C
ºC or over for 1 minute continuously, the inverter is stopped.
(2) When the indoor unit heat exchanger temperature is in the range of A~B ºC, if the inverter command speed is been maintained and the operation has
continued for more than 20 seconds at the same speed, it returns to the normal heating operation.
(3) Indoor blower retains the fan tap when it enters in the high pressure control. Outdoor blower is operated in accordance with the speed.

(a)
Operating conditions:
When the outdoor air temperature sensor (Th5) is -10ºC or lower continues for 5 minutes while
the outdoor speed is other than 0 rps.
