4.3.6.3 Remote Control Optional Functions

b1 Removal of Heating Temperature Compensation (due to Uneven Heat Load).
This function is used when the temperature settings of the remote control switch and the suction air temperature of the
indoor unit are required to be equal.
This is useful when the thermistor at the suction side of an indoor unit is removed and installed in another place..

The setting temperature upper limit after compensation is as follows: Inverter Multi Unit: 34 ºC
b8 Automatic COOL/HEAT Operation
This function is used to operate the unit with changing cooling and heating operation automatically (same operation mode
for indoor units in the same refrigerant cycle).This function is invalid when the outdoor unit is cooling only model or the
function of "Fixing of Operation as Exclusive Cooling Unit" is valid.
C5 Hi Speed
This function is used to increase the fan speed for the high ceiling.
C8 Thermistor of Remote Control Switch
This function is used to control the unit by the built-in thermistor of the remote control switch (remote control thermistor)
instead of the thermistor for suction air.
Set this function at "01" or "02" when utilizing this function.
However, even when this function is set at "01" or "02", the detecting temperature is abnormal due to the failure of the
remote control thermistor, etc., the thermistor to be used is changed to the thermistor for suction air of the indoor unit au-
tomatically.
F2 Remote Control Master-Slave Setting
This function is used when two remote control switches are installed in one system.
Set one remote control switch to "Master" 00, another remote control switch to "Slave" 01.
