Thermostat Control
9.4.1 Without Optional Infrared Presence/Floor Sensor
Whether the thermostat is turned on or off is determined by the difference between the remote
controller set temperature and the actual detected room temperature (
∗
1).
Normal operation
· Cooling operation
· Heating operation
Dry operation
· When Tro < 24.5°C (76.1°F)
· When Tro
≥
24.5°C (76.1°F)
FXTQ-TA only
If the field setting 14(24)-5 is set to
02
, Tro will be the same as the cooling set temperature at the
time of starting dry operation.
∗
1: The thermistor for room temperature detection depends on the field setting 10(20)-2.
