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 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
remote controller 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, and the suction
temperature has changed from 18°C to 30°C (A
→
F):
(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).
Remote controller thermostat sensor is used for temperatures from 23°C to 27°C (C

E).
