(17) Remote Control Thermistor
This function is utilized to control the unit by the built-in thermistor of the remote control switch
(remote control thermistor) instead of the thermistor for suction air.
Set this function at "01" or "02" when utilizing this function.
However, even when this function is set at "01" or "02", the detecting temperature is abnormal due to
the failure of the remote control thermistor, etc., the thermistor to be used is changed to the
thermistor for suction air of the indoor unit automatically.
