Part 4 Functions and Control
Note(s)
Suction air thermistor (
∗
1) is used for temperatures from 23°C (73°F) to 18°C (64°F) (B
→
A).
∗
1. For FTQ: Remote sensor (Optional accessory)
6.2 Thermostat
Control
6.2.1 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)
• FTQ-TA only
If the field setting 14(24)-5 is set to
02
, Tro will be the same as the cooling set temperature.
∗
1: The thermistor for room temperature detection depends on the field setting 10 (20)-2.

T = 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
