For a unit equipped with 3-speed fans, referring to the second image of the auto ext. signal parameter, after fixing
the SP.1,2% and SP.2,3% values (the nominal values at which speed changes from 1 to 2 and from 2 to 3), the
appropriate value to be assigned to the parameter can be obtained as follows:
AutoMax%
This parameter is only available if the auto parameter is set on ext. signal or UR sensor. It can take values between
0 and 99% (1% steps) with the following limit: AutoMin%<AutoMax%
For a unit equipped with variable speed fans:

corresponds to the input signal percentage value for which fans turn at the maximum speed; above
this value, fans remain set at the maximum speed. For instance, the value AutoMin% 080 corres-
ponds to an 8V (80% of 10V) input signal.
For a unit equipped with 3-speed fans, referring to the second image of the auto ext. signal parame-
ter, after fixing the SP.1,2% and SP.2,3% values (the nominal values at which speed changes from 1
to 2 and from 2 to 3), the correct value to be assigned to the parameter can be obtained as follows:
This parameter is only available if the auto parameter is set on CO
0 ppm and 1980 ppm (20ppm steps) with the following limit: AutoMin ppm<AutoMax ppm
For a unit equipped with variable speed fans, it corresponds to the CO
expressed in ppm, for which fans turn at the minimum speed; below this value, fans remain set at
the minimum speed.
For a unit equipped with 3-speed fans, referring to the second image of the auto CO
ter, after fixing the SP.1,2% and SP.2,3% values (the nominal values at which speed changes from 1
to 2 and from 2 to 3), the correct value to be assigned to the parameter can be obtained as follows:
This parameter is only available if the auto parameter is set on CO
20 ppm and 2000 ppm (20ppm steps) with the following limit: AutoMin ppm<AutoMax ppm
For a unit equipped with variable speed fans, it corresponds to the CO
expressed in ppm, for which fans turn at the maximum speed; below this value, fans remain set at
the maximum speed.
For a unit equipped with 3-speed fans, referring to the second image of the auto CO
ter, after fixing the SP.1,2% and SP.2,3% values (the nominal values at which speed changes from 1
to 2 and from 2 to 3), the correct value to be assigned to the parameter can be obtained as follows:
AutoMax ppm=(8×SP.2,3%-3×SP.1,2%)/5
(Default value) It does not affect the system operation.
Its value is expressed in minutes and represents the interval lapsed from the time when the signal of
the extern device for the auto mode has achieved or exceeded the AutoMax%, or Auto Max ppm
value, without dropping below this value, beyond which an anomaly to the external device (CO
HR probe or external signal) is notified.
for values of the 0-10V external signal expressed as a percentage) lower than the set value, the
digital output changes its status.
(or for values of the 0-10V external signal expressed as a percentage) higher than the set value, the
digital output returns to its standard status.
Default value 0500, it is expressed in ppm; for ppm values as read by the CO
set value, the digital output changes its status.
