Regarding nan value of System Airflow and Exit Air Temp

[Nick dan]

Hi

In my entity manager json file, I have added CFM and Exit Air in  entity
Manager data as:
 {
            "C1": 36,
            "C2": 39,
            "MaxCFM": 71,
            "Name": "System Airflow",
            "TachMaxPercent": 100,
            "TachMinPercent": 20,
            "Tachs": [
                "Fan 1",
                "Fan 2",
                "Fan 3",
                "Fan 4",
                "Fan 5",
                "Fan 6"
            ],
            "Type": "CFMSensor"
        },
        {
            "AlphaF": 4.352,
            "AlphaS": 0.512,
            "Name": "Exit Air Temp",
            "PowerFactorMax": 1.2,
            "PowerFactorMin": 0.9,
            "QMax": 165,
            "QMin": 31,
            "Thresholds": [
                {
                    "Direction": "greater than",
                    "Name": "upper critical",
                    "Severity": 1,
                    "Value": 85
                },
                {
                    "Direction": "greater than",
                    "Name": "upper non critical",
                    "Severity": 0,
                    "Value": 80
                },
                {
                    "Direction": "less than",
                    "Name": "lower non critical",
                    "Severity": 0,
                    "Value": 5
                },
                {
                    "Direction": "less than",
                    "Name": "lower critical",
                    "Severity": 1,
                    "Value": 0
                }
            ],
            "Type": "ExitAirTempSensor"
        },
But in exit air, I am getting value as nan fro System airflow and exit air
Can you help me with debugging this ?
