C7110A1010 ROOM AIR QUALITY SENSOR
The sensor cannot distinguish pleasant from unpleasant
smells. The final determination of whether air quality is
satisfactory or not must be made by the persons living or
working in the room. Moreover, various air compositions are
occurring in different rooms.
Thus, the default (factory) setting of the setpoint is
provisional, only. The setpoint must be optimized to
correspond to the subjective feelings of the room occupants.
Adjustment Procedure:
1. Connect sensor and switch operating voltage on.
2. Ensure good air conditions close to the sensor (by
means of ventilation, etc.).
3. After approx. 30 minutes of operation, verify the output
signal. The voltage level should lie in the range
1...3 V. Correct an excessively high or excessively low
voltage level using the trimming potentiometer: The
trimming potentiometer should be turned clockwise
(CW) until the yellow status LED is almost
extinguished. The output signal will then amount to
approx. 1.5 V (max. brightness is reached at 9 V).
NOTE: When first operating the device or after the device
has been powered down for more than 4 weeks
(e.g., during storage), the output signal may vary
during the first 48 hours of operation. In this case,
you should verify the output signal after 48 hours of
operation.

EXAMPLE OF DYNAMIC BEHAVIOR
Fig. 6 shows the dynamic characteristics of the C7110A1010,
monitored during test measurements in a sample room. This
voltage diagram as a function of different occupancy
conditions is only an example and must be proven for other
ambient conditions.
