3.2.2 With Optional Infrared Presence/Floor Sensor
The thermostat ON/OFF condition is determined by the difference between the remote
controller set temperature and the detected temperature around people.
Normal operation
Cooling operation
Dry operation
When Tro ≤ 24.5°C
When Tro > 24.5°C
ΔT = Detected room temperature – Remote controller set temperature
Tro: Detected room temperature at the start of dry operation
Tr: Determined by the room temperature detected by the thermistor
Control range of temperature around people
When the floor temperature is very low, operation using the temperature around people may
cause the suction air temperature to operate outside of use range.
To avoid the above condition, a limit based on the suction air temperature is set for the use
range of the temperature around people.
Cooling operation
When the floor temperature is lower than suction air thermistor detection temperature
(R1T), R1T will be treated as the control target temperature for operation.
When the temperature around people is 15°C or lower, R1T will be treated as the control
temperature for operation.
3.3 Automatic Airflow Rate Control
The automatic airflow rate control (Five steps from H to L) is based on the difference between
control target temperature and set temperature.
