AutoOff ppm
0000
->
2000
This parameter is only available if the auto parameter is set on CO
2
VOC and the digital output is configured as
auto cmp (Factory menu). Default value 0500, it is expressed in ppm; for higher values of ppm as read by the CO
2
probe than the set one, the digital output dedicated returns to its standard status.
Bypass Tmin
12->18
This parameter is on if the by-pass is configured as Universal (Factory menu). Default value 15, it is expressed in
degrees centigrade. It is the minimum temperature value (T min) if By-pass automat. is set in Parameters menu. In
summer season is the minimum return temperature below which the system will close the bypass.
Bypass Tmax
20->30
This parameter is on if the by-pass is configured as Universal (Factory menu).Default value 22, it is expressed in
degrees centigrade. It is the maximum temperature value (T max) if By-pass automat. is set in Parameters menu.
In winter season is the maximum return temperature above which the system will close the bypass.
Filter hours
00000->99999
This parameter is on when the clogged filters alarm is based on the hours of operation of the unit (Factory menu).
Default value 02000, it is expressed in hours. It represents the number of operation hours of the unit after which the
clogged filters alarm is triggered. In order to reset the alarm, the installer will have to set the new limit at which the
alarm must be signaled (check the current operation hours in the parameters status menu Fan hours):
Filters hours = Fan hours + hours for a new alarm
Press. Max
This parameter is only available for units with constant pressure (Factory menu) 1000Pa
Dpexhau.
=XXX%
Dpsupply
067%->150%
This parameter is only available for constant pressure units with control on both flows (Factory menu). Default value
100%, expresses, as a percentage, the desired ratio between the exhaust fan pressure and the supply fan pressure,
which creates an imbalance between the pressures of both flows.
Max speed
055%->100%
UserPassword
This parameter is available if the control is set to run variable speed fans (Factory menu). Default value 100%, it is
the maximum fan speed expressed as a percentage of the nominal value (reduction of the maximum speed). The
maximum speed that can be set in the main window will always be 100% also for Vel.max values lower than 100%;
what changes is the minimum speed value that can be set by the final user:
With this parameter it is possible to enable a password for modifying the set-points, value is 1234.
Yes/No
Setting the parameter to yes you must enter the code in the installer menu access screen to make changes to the
sets. The time available for modifies is 5 minutes, elapsed this password must be entered again.

150%
This parameter is only available for units with constant pressure controlled on both flows. Default value 100%,
expresses, as a percentage, the desired ratio between the exhaust and the supply fan flow, which creates an
imbalance between the flows of both flows.
Max Flow
