Space Temperature Averaging

Space Temperature Averaging with Multiple Sensors

Space temperature averaging for Constant Volume applica- tions is accomplished by wiring a number of remote sensors in a series/parallel circuit.

The fewest number of sensors required to accomplish space temperature averaging is four. Figure 8 illustrates a single sensor circuit (Single Zone), four sensors wired in a series/parallel circuit (Four Zone), nine sensors wired in a series/parallel circuit (Nine Zone). Any number squared, is the number of remote sensors required.

Wiring termination will depend on the type of remote panel or control configuration for the system. Refer to the wiring diagrams that shipped with the unit.

Unit Control Modules (UCM)Control Module Locations for S_HF 30 Ton Units

Unit control modules are microelectronic circuit boards de- signed 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
