When more than one indoor unit (Max. 16 indoor units) are connected in one wired remote controller system:
(1) With the factory default, external input to CnT-6 is effective for only the unit
⓪ .
(2) When setting “For all unit” (Local setting), all units in one remote controller system can be controlled by external
input to CnT-6 on the indoor unit ⓪ .
(3) External input to CnT-6 on the other indoor unit than the unit ⓪ is not effective.
(w) Fan control at heating startup (Applicable model: FDTC and FDUM)
1) Start conditions
At the start of heating operation, if the difference of setting temperature and return air temperature is 5°C or higher after
the end of hot start control, this control is performed.
2) Contents of control
a) Sampling is made at each minute and, when the indoor unit heat exchanger temperature (detected with ThI-R) is
37°C or higher, present number of revolutions of indoor unit fan speed is increased by 10min -1 .
b) If the indoor unit heat exchanger temperature drops below 37°C at next sampling, present number of revolutions of
indoor unit fan speed is reduced by 10min -1 .
3) End conditions
Indoor fan speed is reduced to the setting airflow volume when the compressor OFF is established and at 30 minutes after
the start of heating operation.
(x) Room temperature detection temperature compensation during heating
With the standard specification, the compressor is turned ON/OFF with the thermostat setting temperature. When the thermostat
is likely to turn OFF earlier because the unit is installed at the ceiling where warm air tends to accumulate, the setting can be
changed with the wired remote controller indoor unit function “
”. The compressor and the heater are turned ON/OFF
at one of the setting tempe3, +2 or +1°C in order to improve the feeling of heating. The setting temperature, however,
has the upper limit of 30°C.

(y) Return air temperature compensation
This is the function to compensate the deviation between the detection temperature by the return air temperature thermistor and
the measured temperature after installing the unit.
1) It is adjustable in the unit of 0.5°C with the wired remote controller indoor unit function “RETURN AIR TEMP”.
• +1.0°C, +1.5°C, +2.0°C • -1.0°C, -1.5°C, -2.0°C
2) Compensated temperature is transmitted to the remote controller and the compressor to control them.
Note (1) The detection temperature compensation is effective on the indoor unit thermistor only.
