C8 – Thermistor of Remote Control Switch and Remote sensor
This function is useful when the unit is to be controlled by the thermistor included in the Remote Control or by Remote
Sensor instead of by the suction air thermistor. It determines the thermistor to control the air temperature.
? NOTE
When the function is set to “01” or “02”, if the temperature detected by the remote control thermistor is abnormal due to a fault in the remote
control thermistor or another fault, the Air Inlet Thermistor on the indoor unit is used automatically.
Cg – Not available
CA – Not available
Cb – Selection of forced stoppage logic
This function determines the operating logic for the forced stoppage contacts.
The setting conditions and contact logic are shown in the following table:
Setting condition
Setting Contact Contact logic
Activation contact
Open Closed
00 Contact A Normally open Normal Forced stoppage
01 Contact B Normally closed Forced stoppage Normal
CC – Not used
Cd – Stop of indoor unit fan during cooling Thermo-OFF conditions
Fan stop operation in thermo-o conditions when using the additional remote temperature sensor THM-R2AE (connected
to THM4) or PC-ARFP1E temperature sensor
This optional function keeps the fan stopped when the indoor unit is in Thermo-OFF conditions, even upon start-up.
“Cd=01”: Fan stop operation in thermo-o conditions when using the additional remote temperature sensor THM-R2AE
(connected to THM4) or PC-ARFP1E temperature sensor (“C8=01” must be set in this case).

? NOTE
It is advised to pay attention to the following points:
• Do not set this function if no remote control sensor (in PC-ARFP1E) or remote sensor (THM-R2AE) are installed; otherwise, comfort
conditions may never be reached
• Do not set “Cd” function when indoor unit temperature control is based on:
- “C8=00” : Temperature control with the air inlet sensor of the indoor unit
- “C8=02” : Temperature control with the average value of the remote control sensor and the air inlet sensor of the indoor unit. In
these cases, comfort conditions may never be reached
• In case that Automatic louver is set, the louver will keep operating in both Thermo-ON and Thermo-OFF conditions.
