6.2.2 Description of the optional remote control functions (PC-ARFPE)
b1 – Removal of heating temperature compensation
This function is useful when the thermistor is removed from the suction area of the indoor unit and installed somewhere
else. It is used when the temperature setting displayed on the remote control and the inlet air temperature of the indoor
unit must be the same.
b2 – Circulator function at heating Thermo-OFF
This function is useful when the air in the room is stratied (hot air accumulates at the ceiling). Air stratication may 
occur if LOW has been selected with the heating thermostat off. This function prevents air stratication in the room after 
stopping the air conditioning system.
The circulation pump function maintains the fan speed, whether the thermostat is on or off. Hence, the air movement in
the room is kept at the same level to ensure even air distribution.
? NOTE
• If the indoor unit has an automatic louver, this function also remains active when the heating thermostat is switched off.
• Everyone has a different perception of coolness, heat and air ow and, therefore, this issue should be discussed with the client and
the unit set according to the results of the conversation.
b3 – Forced compressor operation for at least three minutes
This function is used to protect the compressor preventing it from being started or stopped for periods of less than three
minutes. On enabling this function, the mode enabling operations for a minimum of 3 minutes is added.
? NOTE
• In the case of SET-FREE units, this function is standard, even when the setting is not available.
• The compressor stops immediately when the safety device is activated or ON/OFF is pressed.
• To cancel this function, see C7 – Cancellation of the forced compressor operation for at least three minutes.
• When this function is cancelled, the mode enabling operations for a minimum of 3 minutes remains available.
b4 – Pre-determined lter cleaning period change
This function is used to modify the period which the remote control indicates the air lter replacement. The lter cleaning 
period can be changed depending on the condition of the lter.
? NOTE
The remaining number of hours before cleaning the îš¿lter is factory-set for all indoor unit models.
(*)
for RPK units, the factory setting is 200 hours.
b5 – Fixing of operation mode
This function is used when the operating mode does not have to be changed. Once the unit operating mode has been
selected, this function prevents it from being modied from the remote control.
b6 – Fixing of setting temperature
This function is used when the temperature setting does not have to be changed. Once the unit temperature has been
selected, this function prevents it from being modied from the remote control.
b7 – Fixing of cooling operation
This function is available to use refrigeration mode only and to prevent heating mode from being enabled. When this
function is selected, heating operation and the automatic COOL/HEAT operation are cancelled.
b8 – Automatic COOL/HEAT operation
This function allows the automatic change from the cooling to the heating mode for the units with the same refrigerant
cycle.
? NOTE
This function is not valid when the outdoor unit is an exclusive cooling model or when the function to set operations as an exclusive cooling
unit is enabled.
