(c) If the indoor unit fan speed becomes “Me” or “Lo”, Max required frequency goes down
accordingly depending on indoor unit model.
(d) Max. required frequency under high outdoor air temperature in cooling mode
Maximum required frequency is selected according to the outdoor air temperature (Tho-A).

(f) Selection of max. required frequency by heat exchanger temperature
1) Maximum required frequency is selected according to the outdoor unit heat exchanger temperature (Tho-R) during
cooling/dehumidifying or according to the indoor unit heat exchanger temperature (Th
I
-R) during heating mode.
2) When there are 3 indoor unit heat exchanger temperatures (Th
I

(g) When any of the controls from (a) to (f) above may duplicate, whichever the smallest value among duplicated controls is
taken as the maximum required frequency.
(h) During heating, it is operated with the maximum required frequency until the indoor unit heat exchanger temperature
becomes 40°C or higher.
(2)
Compressor start control
(a) Compressor starts upon receipt of the thermostat ON signal from the indoor unit.
(b) However, at initial start after turning the power supply breaker, it may enter the standby state for maximum 30 minutes
(“
PREPARATION” is displayed on the remote controller) in order to prevent the oil loss in the compressor.
If the cooling/dehumidifying/heating operation is selected from the remote controller when the outdoor unit is in the
standby state, “
PREPARATION” is displayed for 3 seconds on the remote controller.
