To set up a CO
2
sensor:
1.
In the Sensor Options section, next to SpaceCO2 sensor type, select the Function option
that is most appropriate for your needs.
Function
Select this option if:
None
The CO
2
sensor on the eZNS network sensor is
not used.
DemandControlVentilation
Demand controlled ventilation system is used
with the CO2 sensors.
MonitoringOnly
The input object AI1004 created but its value will
not be used by the internal algorithm for space
CO2 control.
2.
If you selected DemandControlVentilation, click the “+” sign at the end of the row.
In the CO2DemandVentSetpoint field, enter the CO2 demand ventilation setpoint value.
To set up an occupancy sensor:
1.
In the Sensor Options section, next to OccMotion sensor type, select the Function option
that is most appropriate for your needs.
Function
Select this option if:
None
The occupancy sensor on the eZNS network
sensor is not used.
OccupancyDetection
The motion sensor on the eZNS network sensor
is used to detect occupancy.
MonitoringOnly
Input object BI1005 created but its value will not
be used by the internal algorithm.
2.
If you selected OccupancyDetection, click the “+” sign at the end of the row.
a.
In the MotionOvrdTime field, enter how long the occupancy override should last.
This setting allows the use of momentary contact style occupancy signals.
If you are using maintained-contact occupancy devices, enter zero in this field. In
this case, occupancy statue is only based on contact position.
