Refer to Figure 29 on page 66 and Table 34 on page 67 for element descriptions.
Flow rate
Flow rate value shown in CFM. A value of 000100 equals .100 CFM. A value of 001000
equals 1.000 CFM.
Calibration value
Calibration value of the sensor. A value of 000100 equals a calibration voltage of 1.00 VDC.
Valid ranges are 0.80 to 1.20 VDC. A reported value outside this range will cause a
calibration alarm to be reported in the status byte.
Air temperature
Air temperature reading from the externally attached environmental probe. A value of
000231 equals 23.1°C.
Relative humidity
Relative humidity reading from the externally attached environmental probe. A value of
000561 equals 56.1% RH.
