according to the application code and its needs: this function is
named board to point. After Unit and control type setup, kVent
recognize the mandatory, suggested and optional I/O. Not

configuration mask. Here below the error code meaning and the
possible solutions:

device cannot be enabled with reversible device.

10 Missing c.pCOe I/O error: c.pCOe configured in I/O, but not in unit
setup.
11 Sensors mismatch I/O error: analog input configured as not available
type in that channel.
12 Double DO config. I/O error: same digital output is used for more
functions.
