Function and Control 31

Since the set temperature is shifted by

3.6°F(2°C) higher for 40 minutes, the compressor
speed lowers to save energy. The thermostat goes off due to the shifting of temperature so the
thermostat-off action is prohibited for 40 minutes to prevent this phenomena.
After this 40 minutes, the prohibition of the thermostat-off is cancelled and it resumes conditions
to conduct thermostat-off, depending on the room temperature. In or after this 40 minutes, if the
sensor detects the motion detection signal, it allows the set temperature and the fan speed to
return to the original set point, maintaining normal operation.
Others

The dry operation cannot command the setting temperature with a remote controller, but
internally the set temperature is shifted by 1.8°F (1°C).
