Thermostat Sensor in Wired Remote Controller

Outline
Temperature is controlled by both the thermostat sensor in wired remote controller and air
suction thermostat in the indoor unit. This is however limited to when the field setting for the
thermostat sensor in wired remote controller is set to Use.
Cooling
If there is a significant difference in the set temperature and the suction temperature, fine
adjustment control is carried out using a body thermostat sensor, or using the sensor in the
wired remote controller near the position of the user when the suction temperature is near the
set temperature.
Set temperature
(Ts)
 Assuming the set temperature in the figure above is 24°C, and the suction
(This example also assumes there are several other air conditioners, and the suction
temperature changes even when the thermostat sensor is off.)
Body thermostat sensor is used for temperatures from 18°C to 23°C (A → C).
Wired remote controller thermostat sensor is used for temperatures from 23°C to 27°C (C → E).
Body thermostat sensor is used for temperatures from 27°C to 30°C (E → F).
 Assuming suction temperature has changed from 30°C to 18°C (F → A):
Body thermostat sensor is used for temperatures from 30°C to 25°C (F → D).
Wired remote controller thermostat sensor is used for temperatures from 25°C to 21°C (D → B).
Body thermostat sensor is used for temperatures from 21°C to 18°C (B → A).
