k8 – Control for the prevention of condensation in the louvers
In that units that are equipped with louvers, condensation may occur around the air outlet during operation in cooling or
dry modes, when horizontal air ow or downward air ow are sustained for long periods.
This function is used to prevent condensation by setting the louver swing angle to the third step automatically for 30
minutes every 1 hour.
(In RPK units, this function is activated by means of DSW2-4 instead of the K8 optional function)

L3 – Operation of the louvers in energy-saving Thermo-OFF (Cooling / Dry mode)
Power save must be ON in order to use this function (L5 must be set to 01). This function is used to establish louvre
swinging operation ranging from continuous swing to static operation.
• Low: Continuous louvre swing
• Medium: Louvre swing with intermittent stops for 20/40 seconds
• High: Louvre stopped at full opening position, according to the setting of CF.
L4 – Fan acceleration in energy-saving Thermo-OFF (Cooling mode)
This function increases fan speed by one step to prevent the loss of comfort due to the forced Thermo-OFF for energy
saving during cooling operation.
L5 – Louver swing operation during energy-saving forced Thermo-OFF
This function is used to enabled the setting of function L3.

P1 – Setting temperature in 0.5 ºC steps
This function is used to dene whether setting temperature is adjusted in 0.5 ºC steps (when set to “00”) or in 1 ºC steps
(when set to “01”).
This setting also determines whether the resolution of temperature di󰀨erential of the thermistor is 0.5 ºC (when set to
“00”) or 1 ºC (when set to “01”) enabling more precise setting control.
