Application
701, 702, Identifies the DPM on the Siemens Building Technologies FLN
703, 704, 790 trunk. Valid entries: 0-31, 99.
701, 702, Identification number of the program operating in the DPM.
703, 704, 790 Valid entries: 701, 702, 703, 704, 790.
702, 704 High limit boundary for DIFF PRES2 (Point 31). When the
selected mode of pressurization is negative, DIFF PRES2 must
remain below this limit to prevent an alarm.
Valid entry range: -0.001 to -0.200 inches of H
(-0.249 to -49.8 Pascals).
702, 704 Low limit boundary for DIFF PRES2 (Point 31). When the
selected mode of pressurization is positive, DIFF PRES2 must
remain above this limit to prevent an alarm.
Valid entry range: +0.001 to +0.200 inches of H
(0.249 to 49.8 Pascals).
701, 702, Determines the operating mode for pressurization. ACTIVE mode
703, 704 is either positive or negative pressure [POS, NEG]. NTRAL mode
is neutral pressure.
701, 702, High limit boundary for DIFF PRES1 (Point 30). When the
703, 704 selected mode of pressurization is negative, DIFF PRES1 must
remain below this limit to prevent an alarm.
Valid entry range: -0.001 to -0.200 inches of H
(-0.249 to -49.8 Pascals).
701, 702, Low limit boundary for DIFF PRES1 (Point 30). When the
703, 704 selected mode of pressurization is positive, DIFF PRES1 must
remain above this limit to prevent an alarm.
Valid entry range: +0.001 to +0.200 inches of H
(0.249 to 49.8 Pascals).
701, 702, Indicates that a low pressure alarm is active.
