● Keeping the louvers horizontal during heating (Only heat pump type)
While HOT KEEP is displayed (during hot start operation or when the thermostat has turned off during heating operation),
the louvers stay in the horizontal position to prevent cold drafts, independent of the setting of the AUTO SWING key (auto swing
or stop). The louver position display of LCD displays continuously the original position before this control operation.
When the HOT KEEP display goes out, both the louvers and the LCD display return to their previous position.
(However, after the power supply to the unit is switched on, the louvers swing two times as a check of the power source
frequency, regardless of the settings of the ON / OFF or AUTO SWING keys).

Auxiliary Electric Heater (Only FDF model)
(1) This control is enabled when an auxiliary heater is used. As shown in the drawing below, since the ON/OFF control is
performed by the temperature of the thermostat and the air heat exchanger (both of them conduct electricity during electrical
conditions), control with high responsiveness to the load is performed.
Note that there is no conductivity when the fan for the indoor unit is stopped (including hot start), when the compressor is
stopped and when the defroster is operating.
(2) When the heater changes from conducting to not conducting, even when the indoor fan (FMI) has been stopped (operation
stop by the operating switch or abnormal stop) the indoor fan will operate at low speed for 40 seconds before shutting off to
remove surplus heat from the heater.
