Since the set temperature is shifted by 2°C higher for 40 minutes, compressor speed
becomes low and can realize energy saving operation. But as thermostat is prone to be off
by the fact that the set temperature has been shifted, the thermostat-off action is prohibited
in 40 minutes so as to prevent this phenomena.
After this 40 minutes, the prohibition of the thermostat-off is cancelled and it can realize the
conditions to conduct thermostat-off depending on the room temperature. In or after this forty
minutes, if the sensor detects human motion detection signal, it let the set temperature and
the fan speed return to the original set point, keeping a normal operation.
The dry operation can't command the setting temperature with a remote controller, but
internally the set temperature is shifted by 1°C.
