Function and Control
1.15 Other Functions
1.15.1 Hot-start Function
Heat Pump Only
In order to prevent the cold air blast that normally comes when heating is started, the
temperature of the heat exchanger of the indoor unit is detected, and either the airflow is
stopped or is made very weak thereby carrying out comfortable heating of the room.
*The cold air blast is also prevented using a similar control when the defrosting operation is
started or when the thermostat gets turned ON.
1.15.2 Signal Receiving Sign
When the indoor unit receives a signal from the remote controller, the unit emits a signal
receiving sound.
1.15.3 ON/OFF Button on Indoor Unit
An ON/OFF button is provided on the display of the unit.
Press this button once to start operation. Press once again to stop it.
This button is useful when the remote controller is missing or the battery has run out.
The operation mode refers to the following table.
In the case of multi system operation, there are times when the unit does not activate with
this button.
In case of F(A)TXS20-50G
<Forced operation mode>
Forced operation mode can be started by pressing the ON/OFF button for 5 to 9 seconds while
the unit is not operating.
Refer to "Forced cooling operation mode" on page 251 for detail.
Note:
When the ON/OFF button is pressed for 10 seconds or more, the forced operation is stopped.
1.15.4 Titanium Apatite Photocatalytic Air-Purifying Filter
For F(A)TXS20-50G, ATX20-35G, F(C)(A)TXG25-50E, FVXS25-50F
This filter combines the Air Purifying Filter and Titanium Apatite Photocatalytic Deodorizing
Filter in a single highly effective unit. The filter traps microscopic particles, decompose odors
and even deactivates bacteria and viruses. It lasts for 3 years without replacement if washed
about once every 6 months.
1.15.5 Photocatalytic Deodorizing Filter
For FLK(X)S25-50B
Photocatalytic Deodorizing Filter demonstrates powerful oxidation characteristics when
subjected to harmless ultraviolet light. Photocatalytic deodorizing power is recovered simply by
exposing the filter to the sun for 6 hours once every 6 months.
