4.2.2 Remote Control Thermistor Function
The temperature can be controlled by the built-in thermistor of the remote control switch (remote control
thermistor) instead of the thermistor for the suction air of the indoor unit.
NOTES:
1. Even in case of controlling temperature by the remote control thermistor, the detected temperature by
the thermistor for the suction air of the indoor unit is applied for the activation of the protective devices in
relation with the thermostat for the suction air of the indoor unit.
2. In temperature control by the remote control thermistor, when 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.
3. In case of using this remote control thermistor function, select the location for installing the remote
control thermistor as follows;
* where the average temperature of the room can be detected.
* where the thermistor is not exposed to the sunlight directly.
* where the heat source is not near the thermistor.
* where the outdoor air do not affect the room temperature by opening and closing the door, etc.
4. In case of using two remote control switches (Main and Sub), this remote control thermistor function is
available only for the main remote control switch.
