General Information
Space Temperature Averaging with Multiple Sensors Unit Control Modules
(UCM)
Unit control modules are microelectronic circuit boards designed to perform specific unit
functions. These modules through Proportional/Integral control algorithms provide the best
possible comfort level for the customer. They are mounted in the control panel and are factory
wired to their respective internal components. They receive and interpret information from other
unit modules, sensors, remote panels, and customer binary contacts to satisfy the applicable
request for economizing, mechanical cooling, heating, and ventilation. Figure 9 below illustrates
the typical location of each “1U” designated module.
