Room Temperature Thermistor in Remote Controller

Temperature is controlled by both the room temperature thermistor in remote controller and
suction air thermistor () in the indoor unit. (This is however limited to when the field setting for
the room temperature thermistor in remote controller is set to "Use.")
Note: When outdoor air is introduced to the air conditioner with mixed into indoor air, the room
temperature may fail to be set temperature, since TS and TH1 do not enter the area of "use
range of remote control thermistor." In such a case, put the remote sensor (optional accessory)
in your room, and use it with setting "do not use remote control thermostat."
 For FTQ: Remote sensor (Optional accessory)
Cooling
If there is a significant difference in the set temperature and the suction air temperature, fine
adjustment control is carried out using suction air thermistor () in the indoor unit, or using the
room temperature thermistor in the remote controller near the position of the user when the
suction air temperature is near the set temperature.

 Ex: When cooling
Assuming the set temperature in the figure above is 75°F, and the suction air
temperature has changed from 64°F to 86°F (A  F):
(This example also assumes there are several other air conditioners, the system is OFF, and
that temperature changes even when the thermostat is OFF.)
Suction air thermistor () is used for temperatures from 64°F to 73°F (A  C).
Room temperature thermistor in remote controller is used for temperatures from 73°F to 81°F
(C  E).
Suction air thermistor () is used for temperatures from 81°F to 86°F (E  F).
And, assuming suction air temperature has changed from 86°F to 64°F (F  A):
Suction air thermistor () is used for temperatures from 86°F to 77°F (F  D).
Room temperature thermistor in remote controller is used for temperatures from 77°F to 70°F
(D  B).
Suction air thermistor () is used for temperatures from 70°F to 64°F (B  A).
