Regarding control target temperature
When using the infrared presence/floor sensor, the temperature around people will be treated
as the control target temperature for operation.
What is the temperature around people?
The temperature around people refers to the temperature of the living space, obtained from the
temperature around the ceiling and the temperature underfoot. The temperature is calculated
using the detected values of the suction air thermistor and the infrared presence/floor sensor.
It is difficult to use only suction air temperature control for underfoot air conditioning.
8.2 Thermostat Control
8.2.1 Without Optional Infrared Presence/Floor Sensor
The thermostat ON/OFF condition is determined by the difference between the remote
controller set temperature and the actual detected room temperature (
1).

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
