Whether the thermostat is turned on or off is determined by the difference between the remote
controller set temperature and the detected temperature around people.

T = Room temperature or temperature around people – Remote controller set temperature
Tro: Room temperature or temperature around people at the start of dry operation
Tr: Room temperature or temperature around people
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 temperature (R1T), R1T will be treated as
the control target temperature for operation.
When the temperature around people is 15°C (59°F) or lower, R1T will be treated as the control
temperature for operation.
Heating operation
When the floor temperature is higher than suction air temperature (R1T), R1T will be treated as
the control target temperature in operation.
When the temperature around people is 33°C (91.4°F) or higher, R1T will be treated as the
control temperature for operation.
