Allow an external controller to start
or stop the system, or to perform
an emergency stop.
* If an emergency stop is performed
from an external controller, all refriger-
ant systems will be disabled.
* If forced stop is set, indoor unit stops
by the input to the external input
terminals, and Start/Stop by a remote
controller is restricted.
Change the target for reporting errors.
Errors can either be reported in all lo-
cations, or only on the central remote
controller.
When set to 01, the fan stops
when the thermostat is OFF in
cooling operation. Connection of
the wired remote controller (2-wire
type) and switching its thermistor
are necessary.
• Set this function when connecting
the VRF system to a ventilator,
economizer, humidifi er, or other
external device.
• The connection terminal functions
can be changed depending on
the type of external device. For
details of the connection terminal
functions, see the Design & Tech-
nical Manual.
Sets the control method for the
external heater being used. For
details of the control method, see
the Design & Technical Manual.
• Sets the temperature conditions
when the external heater is ON.
• For the temperature conditions,
see "Temperature conditions
when the external heater is ON".
For a more detailed explana-
tion, see the Design & Technical
Manual.

*1: Auto restart is an emergency function such as for power failure etc.
Do not start and stop the indoor unit by this function in normal operation.
Be sure to operate by the control unit, converter or external input device.
*2: Inappropriate setting may cause an external device malfunction. Confirm whether all
the settings have been performed appropriately according to the installing condition.
*3: When using function number 75, inappropriate heater selection may cause cold air in
defrosting.
