∗
4. The control of auxiliary electric heater connected to FXTQ-TA models differ from this flowchart.
For details, refer to Heater Control (FXTQ-TA Models) on page 79.
∗
5. If the evaporator inlet temperature is kept at not more than –5°C (23°F) for a period of
cumulative 10 min. or not more than –1°C (30.2°F) for a cumulative period of 40 min., freeze-
up prevention operation will be conducted. If the evaporator inlet temperature is kept at not
less than 7°C (44.6°F) for a consecutive period of 10 min., the freeze-up prevention operation
will be reset.
∗
6. Thermostat status
∗
7. The FXFQ series have the drain pump as standard equipment.
∗
8. Program dry display
No set temperature and airflow rate of the remote controller are displayed.
∗
9. Thermostat status
Set temperature when operating the program dry mechanism.
∗
10. Fan operation
By setting the remote controller to Fan, the fan will operate with thermostat OFF in set
temperature control operation mode.
∗
11. Set wind direction
According to wind direction instruction from the remote controller, the wind direction is set to
100% horizontal while in heating operation.
∗
12. Fan
According to fan speed instruction from the remote controller, the fan is put into operation in LL
mode while in heating operation.
∗
13. Wind direction
When the heating thermostat turns OFF, the wind direction will be set to 100% horizontal.
∗
14. Hot start
If the condenser inlet temperature exceeds 34°C (93.2°F) at the time of starting operation or
after the completion of defrost operation, or until 3 minutes pass or Tc is above 52°C
(125.6°F), hot starting will be conducted.
∗
15. Thermostat status
∗
16. Outlet air temperature drop protection
When the set temperature is below 24°C (75.2°F) or the electronic expansion valve opening is
small, the protection will be activated.
