9.3 Remote
Controller
Thermistor
Temperature is controlled by both the remote controller thermistor and suction air thermistor for the
indoor unit. (This is however limited to when the field setting for the remote controller thermistor is
set to Use.)
When fresh air intake kit is used, outdoor air is mixed with indoor air, and the room temperature
may not reach the set temperature, since TS and TH1 do not enter the area in which remote
controller thermistor can be used. In such case, install the remote sensor (optional accessory) in
your room, and set the field settings to not use the remote controller thermistor.
∗
FXTQ-TA and CXTQ-TA models do not have this control because they do not have suction air
thermistor. The thermistor is selectable manually when remote sensor (optional accessory) is
installed.
Cooling
If there is a significant difference in the set temperature and the suction temperature, fine
adjustment control is carried out using a suction air thermistor, or using the remote controller
thermistor near the position of the user when the suction temperature is near the set temperature.
Assuming the set temperature in the figure above is 24
°
C (75
°
F), and the suction
temperature has changed from 18
°
C (64
°
F) to 30
°
C (86
°
F) (A
→
F):
(This example also assumes there are several other air conditioners, and the suction temperature
changes even when the thermostat is off.)
Suction air thermistor is used for temperatures from 18°C (64°F) to 23°C (73°F) (A
→
C).
Remote controller thermistor is used for temperatures from 23°C (73°F) to 27°C (81°F) (C
→
E).
Suction air thermistor is used for temperatures from 27°C (81°F) to 30°C (86°F) (E
→
F).
