UCM Control System

The IntelliPak™self-contained units are controlled by a
microelectronic control system that consists of a network
of modules and are referred to as Unit Control Modules
(UCM).
The unit size, type, heating functions, peripheral devices,
options, exhaust capabilities, etc. determine the number

and type of modules that a particular rooftop unit may
employ.
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.
By processing analog and binary inputs, each module
supplies outputs in the form of modulating voltages (from
