1) The external device can be operated in accordance with the
outdoor temperature in cooling operations. Energy saving
operations can be realized even if a cooling load exists in
the winter, by combining a device that uses the outdoor
temperature.
2) This function is valid by setting the CODE No. (DN) [1C8]
from the wired remote controller, and when the outdoor
temperature satisfies certain conditions, the output for the
CN32 connector on the indoor P.C. board will turn ON.
* Use processed air when taking in fresh air.
Watch for condensation of devices when taking in fresh air
at low temperatures.
3) The temperature condition can be set with the following
CODE No. (DN).
4) The output for CN32 will turn OFF if there is a trouble in
the TO sensor.
5) The output state can be checked from “Monitor function” on
the wired remote controller.
* Refer to page 82 or or the manual for the remote controller for
