(When the unit is not running, the display changes
between indoor temperature and no display.)Indoor
temperature is the temperature of the suction air
measured by the room thermistor, and outdoor
temperature is that measured by the outdoor
temperature thermistor. When indoor temperature
is displayed, the indoor LED on the main unit is lit,
and when outdoor temperature is displayed, the
outdoor LED is lit. For 90 seconds after the
operation starts, - - is displayed instead of the
actual outdoor temperature since it is still being
measured.Because of the effect of the exchanger,
the unit cannot confirm the exact indoor
temperature right after the operation is terminated.
Therefore, for one hour since the operation is
stopped, the indoor temperature immediately before
the operation is stopped is displayed. After over
one hour since it is stopped, the unit displays the
actual room temperature at that point.
