b5 Fixing of Operation Mode
This function is used when operation mode changes are not required.
When this function is valid, the operation mode which has been set cannot be changed by the remote control switch.
b6 Fixing of Setting Temperature
This function is used when setting temperature changes are not required. When this function is valid, the setting tempera-
ture which has been set cannot be changed by the remote control switch.
b7 Fixing of Operation as Exclusive Cooling Unit
This function is used when exclusive cooling operation is required. This function invalidates the heating operation and the
automatic COOL/HEAT operation, as the operation of exclusive cooling unit.
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.
b9 Fixing of Fan Speed
This function is used to fix the fan speed. When this function is valid, the fan speed is not changed by the remote control
switch.
bA Not Prepared
bb Cooling Setting Temperature Compensation
This function is used to provide the longer cooling operation time. When this function is valid, Thermo-ON/OFF is con-
trolled under the lower temperature conditions than the setting temperature (indicated value) of the remote control switch.

C4 Drain pump in heating mode
This function is used to activate the drain pump in heating mode (when the humidifier is installed).
C5 Static pressure selection (RPI) / Increasing fan speed (RCD, RCI, RCIM)
For RPI units, this function is used to change the static pressure.
For RCD, RCI and RCIM units, this function is used to increased the fan speed on the indoor units installed in high ceilings.
C6 Hi Speed at Heating Thermo-OFF
This function is used to increase the fan speed when thermo-OFF in heating operation with the function (C5). (The fan
speed is not increased when thermo-OFF in heating operation at the function (C5) setting.)
