Out of Range Error
Accompanies most of other errors.
Can also indicate overload or failures
of sensors and inputs.
Resets automatically after source of
error disappearance.
Try sensor in fresh air.
Check connections of temperature and
relative humidity probe.

Warm Up state
Is always set after power up or power
failure. Resets after restart sequence
If it doesn’t disappear in half a minute,
check power stability.

Error codes
Note 1. Any probe is out of range. Occurs, for instance, during over exposure of CO
2
sensor, in which
case the error code will automatically reset when the measurement values return to normal. Could
also indicate the need of zero point calibration. A background calibration using push button function
”bCAL” will cure this error (a more exact zero calibration using ”CAL” may be performed later, if
required). If the CO
2
readings are normal, and still the error code remains, the temperature or relative
humidity sensor can be defect or the connections to these are broken.
Please remark: If several errors are detected at the same time the different error code numbers
will be added together into one single error code!
