5 Optional functions
Optional functions through Remote control
E9 – Intermittent fan operation in heating stop
In case that the indoor unit is stopped (in SW OFF), under certain conditions the fan operation at Slo speed is performed
for 3 minutes after 30 minutes of stoppage. Not available for models RPF(I)FSN2E.
EA – Not used
Eb – Fan operation control at cooling Thermo-OFF
This function reduces the unit fan speed to reduce the spreading of smells and humidity.
EC – Forced Thermo-ON stoppage at cooling operation
This function is used to force Thermo-ON during 6 minutes when stopping in cooling operation. It is effective for avoiding
unpleasant smells, as the heat exchanger remains clean, e.g. it is rinsed with drainage water.
Ed – Not used
EE – Automatic fan speed control
This function limits indoor fan speed when room temperature is close to setting temperature.
• When EE: Automatic indoor fan speed mode is set to "01: Enabled" in the function selection of the remote control,
operation is carried out in automatic indoor fan speed mode.
• When setting fan speed is set as to "Auto" with the remote control, operation is carried out in automatic indoor fan
speed mode with "High wind" as setting fan speed.
• Cooling
Indoor control temperature (Ti2) - Setting temperature 2 (Ts2) ≥ 2ºC: Setting fan speed
-
Indoor control temperature (Ti2) - Setting temperature 2 (Ts2) ≥ 1ºC: Medium (Low when setting fan speed is Low)
-
Indoor control temperature (Ti2) - Setting temperature 2 (Ts2) < 1ºC: Low
-
Setting fan speed
• Heating
- Setting temperature 2 (Ts2) - Indoor control temperature (Ti2) ≥ 2ºC: Setting fan speed
Setting temperature 2 (Ts2) - Indoor control temperature (Ti2) ≥ 1ºC: Medium (Low when setting fan speed is Low)
-
Setting temperature 2 (Ts2) - Indoor control temperature (Ti2) < 1ºC: Low
-
• Maintenance of fan speed for 3 minutes
- In switch ON with the remote control, fan speed is set to the setting fan speed, and then it enters in automatic
mode after 3 minutes have passed. The switching of fan speed depending on temperature differential is
performed when entering in the automatic mode, regardless of being in Thermo-ON or Thermo-OFF.
- Once that fan speed is switched after Thermo-ON, the fan speed after the change is maintained for 3 minutes. (*)
The aforementioned switching of fan speed depending on temperature differential is performed after 3 minutes
have passed. Setting Temperature is the Temperature used for Thermo-OFF.
When switching fan speed due to a function of the motion sensor, it is switched immediately even during the
-
3 minutes of maintenance of fan speed.
