(20) Selection of cooling/heating external input function
(a) When “External input 1 setting: Cooling/heating” is set by the indoor unit function from remote control, the cooling or
heating is selected with CnT-6 or CnTA.
(b) When the external input 1 method selection: Level input is set by the indoor unit function:
・
CnT-6 or CnTA: OPEN → Cooling operation mode
・
CnT-6 or CnTA: CLOSE → Heating operation mode
(c) When the external input 1 method selection: Pulse input is set by the indoor unit function:
If the external input is changed OPEN → CLOSE, operation modes are inverted (Cooling → Heating or Heating →
Cooling).

(d) If the cooling/heating selection signal is given by the external input, the operation mode is transmitted to the remote
control.

(21) Room temperature detection temperature compensation during heating
With the standard
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 control indoor unit function “
”. The compressor and the heater are turned ON/OFF at
one of the setting temperature +3, +2 or +1°C in order to improve the feeling of heating. The setting temperature, however, has
the upper limit of 30°C.

(22) 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.
(a) It is adjustable in the unit of 0.5°C with the wired remote control indoor unit function “RETURN AIR TEMP”.
• +1.0°C, +1.5°C, +2.0°C • -1.0°C, -1.5°C, -2.0°C
(b) Compensated temperature is transmitted to the remote control and the compressor to control them.
Note (1) The detection temperature compensation is effective on the indoor unit thermistor only.
(19) Temporary stop input
In case of temporary stop, operation lamp of remote control lights, but indoor/outdoor unit stop the operation.
(a) In case of “level input” setting (Factory default)
Input signal to CnT-6 or CnTA is OFF → ON : Temporary stop
Input signal to CnT-6 or CnTA is OFF → ON : Normal operation
(b) In case of “pulse input” setting (Local setting)
It is effective only when the input signal is changed OFF→ON, and “temporary stop/normal operation” is inverted.
