b) Once the fan motor is changed from OFF to ON during the thermostat ON, the indoor fan motor is not turned
OFF even if the heat exchanger thermistor detects lower than °C.
Note () When the defrost control signal is received, it complies with the fan control during defrosting.
c) Once the hot start is completed, it will not restart even if the temperature on the heat exchanger thermistor drops.
2)
During the hot start, the louver horizontal control signal is transmitted.
3)
When the fan motor is turned OFF for  minutes continuously after defrosting, the fan motor is turned ON regardless
of the temperatures detected with the indoor heat exchanger thermistors (ThI-R, R).
(iii) Ending condition
1) If one of following conditions is met during the hot start control, this control is terminated, and the fan is operated with
the set airflow volume.
a) Heat exchanger thermistor (ThI-R or R, whichever higher) detects °C or higher.
b) It has elapsed  minutes after starting the hot start control.
(g) Hot keep
Hot keep control is performed at the start of the defrost control.
1) Control
a) When the indoor heat exchanger temperature (detected with ThI-R1 or R2) drops to 35°C or lower, the speed of
indoor fan is changed to the lower tap at each setting.
b) During the hot keep, the louver horizontal control signal is transmitted.
2) Ending condition
When the indoor fan is at the lower tap at each setting, it returns to the set airflow volume as the indoor heat exchanger
temperature rises to 45°C or higher.
(h) Thermostat operation
(i) Cooling
1)
Thermostat is operated with the room temperature control.
2) Thermostat is turned ON or OFF relative to the set room temperature as shown below.
Thermostat OFF
3)
Thermostat is turned ON when the room temperature is in the range of - < Set point < + at the start of cooling opera-
tion (including from heating to cooling).
(ii) Heating
1)
Thermostat is operated with the room temperature control.
2)
Thermostat is turned ON or OFF relative to the set room temperature as shown below.
Heater ON
-1
3) Thermostat is turned ON when the room temperature is in the range of - < Set point < + at the start of cooling opera-
tion (including from cooling to heating).
(iii) Fan control during heating thermostat OFF
1)
Following fan controls during the heating thermostat OFF can be selected with the indoor function setting of the wired
remote controller.
① Low fan speed (Factory default), ② Set fan speed, ③ Intermittence, ④ Fan OFF
