1. Room Temperature Control

1. Room Temperature Control

The body sensor or remote controller sensor detects temperature in the room. The detected temperature is
called the room temperature. The body sensor is the one contained in the indoor unit.
Set temp.
Detected temp. by
sensor
Room temp.
The thermostat is turned ON or OFF according to the following T.
T (Cooling)
2
T (Heating)
Correction temperature (only during heating)
If the indoor unit is installed on the ceiling, temperature near the ceiling is higher than near the floor. When
the body sensor is enabled, lower temperature near the floor must be considered. To correct this difference in
temperature, the correction temperature is used.
The factory setting for the correction temperature is different depending on the model. See "14. Parameter".
Example: Cooling temperature correction
