BACnet Configuration
BACnet Objects Descriptions
Depending on the model, the IAQPoint can be configured with only one
measurement type (CO2) or with three measurement types (CO2,
temperature and humidity). Each measurement type has both Analog
Input (AI) and Analog Value (AV) objects. The table below explains each
object and provides its default setting:
CO2 Measurement:
AI CO2 Conc.
AV CO2 SP
AV Alr A
AV Hyst A
AV Alr B
AV Hyst B
Temperature Measurement: (only with temperature and humidity option)
AI Temp.
AV Temp. SP
Humidity Measurement: (only with temperature and humidity option)
AI RH
AV RH SP
* Setpoints are used when the IAQPoint is connected to an external
system that can manage and maintain desired levels.
All object points are READ ONLY
42
The CO2 gas reading
Default setpoint 850 ppm. The ideal level of CO2 that
should be maintained*
Default value 850 ppm. The level at which Alarm A will
be triggered
Default value -50. Alarm A hysterysis offset (Alr A +
Hyst A = level at which alarm will be deactivated)
Default value 1200 ppm. The level at which Alarm B will
be triggered
Default value -50. Alarm B hysterysis offset (Alr B +
Hyst B = level at which alarm will be deactivated
The temperature reading
Default setpoint 22º: The ideal temperature to be
maintained*
The humidity reading
Default setpoint 50%: The ideal humidity level to be
maintained*
