carbon monoxide (CO). Zero CO will zero the CO sensor readings
that may have drifted. Initiating the Zero CO function will show the
sensor CO reading and the time remaining.

The Zero CO function should be performed in an area where no
combustion is taking place which may affect zeroing of the sensor.
