If the installation location of the outdoor unit is
exposed to direct sunlight, the outdoor air
temperature sensor will be unable to measure the
actual outdoor ambient temperature correctly.
In this case, optional outdoor temperature sensor
can be fixed at a suitable location to more
accurately measure ambient temperature.
