Installation instructions
In these extreme conditions, the automatic mode sets the
fan at minimum speed, in order to isolate as much as
possible the internal environment from the external one and
at the same time preserve the ambient comfort.
Low humidity emergency speed can be modified by in-staller
by the mean of "ErHs", included into "Par" menu.
Wet climate ventilation mode is effective in case a cool-ing
system with dehumidification is in place. In this case it is
advisable to enable the function by operating on variable HrHis.

If "PARTY" mode is enabled, fan speed is increased
respect to the nominal speed.
"PARTY" mode is a timed function (default 3 hours).
The speed percentage of the "PARTY" mode is set as
a parameter by the installer according to the
customisation requested by the user, starting from the
standard value of 130% compared to the nominal speed.
The duration of the "PARTY" mode can be changed by
100%
accessing the TECHNICAL Menu and Par sub menu via
the "Tbst" parameter.
