® Chapter 8 Constant-volume AHU with warm-up, pre-cool, and communications Figure 182: Indicating mode within nvoUnitStatus Output block, you must select the appropriate element of nvoUnitStatus (Figure 182). Figure 183: Remaining unit status items The remaining elements, with the exception of alarm status, are indicated as a percentage because the type of each element is SNVT_lev_percent. In most cases, simply connect the appropriate variable or output status to the corresponding network variable output. Be sure to select the appropriate element of nvoUnitStatus. For the supply fan status, indicate 0% when the unit is off and 100% when the unit is running. Alarm status, which is a Boolean value, uses the output status of the Alarm Output binary output (Figure 183). All communications requirements of the sequence of operation are now fulfilled. Compile and download the completed program (Figure 184 on page 223) to the controller. 222 CNT-APG001-EN
