a second side configured to face an enclosure interior;
a flange that surrounds the system and is configured for attachment to an opening of the enclosure;
a thermostat;
one or more fans;
one or more compressors; and
a controller panel comprising a digital controller, a user interface, and a voltage divider; the digital controller being configured to:
utilize two or more set points and input from the thermostat to variably control one or more of the one or more fans and one or more compressors using a constant input of 48 volts that is converted to differing amounts of variable direct current (VDC) outputs;
the voltage divider being configured to separate a line voltage from the user interface of the controller panel, lowering the line voltage provided to the user interface.
