Modules (UCM).
The unit size, type (CV or VAV), heating functions, peripheral devices, options, exhaust
capabilities, etc. determine the number and type of modules that a particular rooftop
unit may employ.
The UCM receives analog and binary inputs, then processes this information and
supplies outputs in the form of modulating voltages, contact closures, etc. to control
damper actuators, fan motors, compressors, valves, electric heating coils and other
electrical devices in the unit to maintain set comfort levels.
The UCM provides some equipment protection functions both directly and indirectly,
such as duct pressure limits and compressor lockouts.
Listed below are the various modules that may be employed in a UCM control system.

assemblies to measure fresh air flow entering the unit. These measurements are
converted to CFM and added to give total fresh air flow. This value can be used for
monitoring purposes, to maintain flow to a minimum fresh air flow SETPOINT, or to
maintain appropriate CO2levels in the controlled space using its space CO2sensor
input and the DCV feature. Without TRAQ assemblies installed the VCM can use DCV
and the CO2sensor input to control OA Damper minimum position to maintain CO2
levels in the space. A preheat control relay output is also provided on this module to
maintain tempered outdoor air during ventilation using the VCM Auxiliary Temperature
input. The preheat unit is user-supplied.
Multi Purpose Module (1U9 IntelliPak II) (1U105 IntelliPak I) (Optional - used
with Return Fan Control)
The MPM supports the function of return plenum pressure control by providing inputs
for measuring return plenum pressure, calibrating that reading, and providing an

Factory Presets
The UCM controlled unit has many operating functions which are preset at the factory,
but may be modified to meet the unique requirements of each job. The following list
identifies each of the unit’s adjustable functions and the value assigned to it. If these
factory presets match the application’s requirements, simply press the AUTO key at the
Human Interface module to begin unit operation (after completing the Pre-Start and
Start-Up procedures in the Installation, Operation, and Maintenance manual). If the
application requires different settings, turn to the listed page beside the function, press
the designated function menu key, then press and hold the NEXT or PREVIOUS key
until its screen appears on the LCD. Once the proper screen appears, simply follow the
programming instructions given below the applicable screen in this manual.
Note: Record any changes made to the factory-preset values in the corresponding
space provided.
