AURORA UPC ZS ZONE SENSORS INSTALLATION GUIDE
CO2 sensor installation
IMPORTANT
Do not install ZS CO
2
sensors in continuous occupancy applications. For a ZS CO
2
sensor to
maintain accuracy, it must be installed only in a zone that is unoccupied for at least 4 hours a day with enough air
movement during the unoccupied period to return CO
2
to background levels.
A ZS sensor with CO
2
uses Automatic Background Calibration which waits for the lowest value in a 24-hour period
that deviates no more than 40PPM for at least 15 minutes, and assigns that value to the 400PPM baseline. This
daily Automatic Background Calibration may take up to 21 days to fully calibrate the sensor.
NOTE
Dropping a sensor can upset the calibration, and it may require 21 days to return to our stated accuracy.
Motion sensor installation
The motion sensor on a ZS Pro needs to have a direct line of sight to the occupants in the room.
If the size of the room exceeds the maximum detector range, use multiple sensors to adequately monitor the area.
Avoid placing the sensor:
x
In a location that has a direct line of sight through an open door to a hallway where the sensor could detect
movement of people in the hallway.
x
Near air ducts. Rapidly changing air currents from the air ducts could lead to false sensor readings.
To address a ZS zone sensor
Each ZS Sensor on an Rnet must have a unique address, but addresses do not have to be sequential.
Use the DIP switches on the back of the ZS zone sensor to set an address from 0 to 14. (0 is factory default.) Each
DIP switch has the value shown in the figure below. Turn on as many DIP switches as you need so that their total
value equals the address.

EXAMPLE
DIP switches 1 and 4 above
are on. Their values (1 + 8) total 9, so
the sensor's address is 9.
