Phase Monitor

Unit is equipped with phase monitor in control box.
The phase monitor will protect against phase loss,
imbalance and reversal of line voltage. If a fault occurs,
the red LED will energize. While the fault condition is
present, the phase monitor interrupts the 115V control
circuit. If no faults are observed, a green LED will be
energized.

Unit Control Components

The self-contained unit is controlled by a
microelectronic control system that consists of a
network of modules. These modules are referred to as
unit control modules (UCM). In this manual, the
acronym UCM refers to the entire control system
network.
These modules perform specific unit functions using
proportional/integral control algorithms. They are
mounted in the unit control panel and are factory wired
to their respective internal components. Each module
receives and interprets information from other unit
modules, sensors, remote panels, and customer binary
contacts to satisfy the applicable request; i.e.,
economizing, mechanical cooling, heating, ventilation.
Following is a detailed description of each module's
function.
