5 Optional functions
Optional functions through Remote control
K5 – Detection level of the motion sensor kit
This function is used to determine the amount of human activity depending on the reaction rate.
When "High" is set, the detection level becomes more sensitive. When "Low" is set the sensor becomes lower.
Human activity
Large
Small
Not available
K6 – Selection of allowed operation modes
This function is used to select the operation modes in which the setting of C8 (use of remote control switch sensor or
remote sensor on THM4 to control the indoor unit) is enabled.
K7 – Not used
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 flow or downward air flow 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)
K9 – Not used
KA – Not used
L1 – Not used
L2 – Not used
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.
L6 – Not used
L7 – Not available
L8 – Not used
L9 – Not used
LA – Not used
Lb – Not used
