Setpoints

The LC6000 setpoints will determine the cooling and
heating setpoints when communicating with the wall-
mount units. The unit cooling and heating setpoints
will determine the cooling and heating setpoints when
in orphan mode. It is important to note that once the
wall-mount unit establishes communication with the
LC6000, the setpoints from the LC will override the
wall-mount unit setpoints. If a unit returns to orphan
mode after communicating with LC, it will operate with
last communicated setpoints from the LC.
If at any time the unit(s) loses communication with
the LC6000 controller, the unit(s) will go into orphan
mode.
