Outline of Control (Indoor Unit)
Thermostat Sensor in Remote Controller
Temperature is controlled by both the thermostat sensor in remote controller and air suction thermostat in the
indoor unit. (This is however limited to when the field setting for the thermostat sensor in remote controller is set
When OA (outdoor air) is introduced to the airconditioner with mixed into indoor air, the room temperature may
fail to be preset temperature, since TS and TH1 do not enter the area of "use range of remote control
thermostat." In such a case, put the remote sensor (optional accessory) in your room, and use it with setting "do
not use remote control thermostat."
If there is a significant difference in the preset temperature and the suction temperature, fine adjustment control
is carried out using a body thermostat sensor, or using the sensor in the remote controller near the position of the
user when the suction temperature is near the preset temperature.
Ex: When cooling
Assuming the preset temperature in the figure above is 75°F, and the suction temperature has changed
from 64°F to 86°F (A → F):
This example also assumes there are several other air conditioners, the VRV system is off, and that temperature
changes even when the thermostat sensor is off.
Body thermostat sensor is used for temperatures from 64°F to 73°F (A → C).
Remote controller thermostat sensor is used for temperatures from 73°F to 81°F (C → E).
Body thermostat sensor is used for temperatures from 81°F to 86°F (E → F).
And, assuming suction temperature has changed from 86°F to 64°F (F → A):
Body thermostat sensor is used for temperatures from 86°F to 77°F (F → D).
Remote controller thermostat sensor is used for temperatures from 77°F to 70°F (D → B).
Body thermostat sensor is used for temperatures from 70°F to 64°F (B → A).
