For a ZS CO2 sensor tomaintain accuracy, it must be installed only in a zone that is unoccupied for at least 4 hours a day with enough airmovement during the unoccupied period to return CO2 to background levels.A ZS sensor with CO2 uses Automatic Background Calibration which waits for the lowest value in a 24-hour periodthat deviates no more than 40PPM for at least 15 minutes, and assigns that value to the 400PPM baseline. Thisdaily 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 installationThe 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:• In a location that has a direct line of sight through an open door to a hallway where the sensor could detectmovement of people in the hallway.• Near air ducts. Rapidly changing air currents from the air ducts could lead to false sensor readings.
