The shift from one operating mode to the other is
achieved by pressing the MODE button for at least 0.5

Disabling certain commands (by the Installer)
To satisfy the requirements of some specific application
certain functions accessible through the remote control
may be disabled by the installer. In this case the
appliance will operate in AUTO mode only: the user
can only set the TIMER function and change the time or
day of the week using the SET button to set the TIMER
and display:
the actual temperature of the stail air, before the heat
exchanger;
the relative humidity percentage of the stail air, before
the heat exchanger;
the CO 2 concentration of the stail air, before the heat
exchanger;
the TIMER setting.
Pressing the other buttons, will be considered an
accidental event and will cause any action.
Prevention of changes to V min and V max speed
The installer can prevent others from making changes to
the maximum and minimum speed settings once he has

Warning/error signals
• Exceeding the CO 2 threshold generates an alarm
condition, which results in the flashing of the CO 2
value on the remote control display. The appliance
starts running at Max speed until CO 2 level has
dropped.
• Low battery is indicated on the remote control by a
flashing of the relative icon
(a sequence of double BEEPs).
batteries have been replaced, the acoustic warning
will stop and the icon will go off.
• The dirty filter condition is indicated by an acoustic
signal (a sequence of triple BEEP's) and the flashing of
the relative icon
the filter maintenance or cleaning procedure is being
carried out.
• The saturated filter condition is indicated with an
acoustic signal (a continuous sound) and the
permanent display of the relative icon
event, the appliance automatically stops the motors
and opens the by-pass valve to ensure that there is
however at least some air circulation. This signal is
interrupted when the filter maintenance or cleaning
procedure is being carried out.
Error warnings are indicated
relative codes (ER01, ER02, etc...) and an acoustic
warning signal (a sequence of double BEEPs). These
warnings will remain in effect until the regular operating
conditions of the appliance have been restored, or the
appliance has been turned off. The malfunctions will be
indicated as:
ER01 : by-pass / de-frosting valve blocked;
ER02 : blockage of the fan motor intaking fresh air from
outside;
ER03 : blockage of the motor discharging the stale air to
outside;
ER04 : the remote control does not receive signals from
the appliance
ER05 : the remote control is not transmitting signals to
the appliance.
ER06 : the temperature sensor in the external fresh air
intake duct upsteam of the exchanger is not active;
ER07 : the temperature sensor in the external fresh air
intake duct downsteam of the exchanger is not active;
ER08 : the temperature sensor in the stale air outlet
delivery duct from the house downstream of the
exchanger is not active;
ER09 : the Relative Humidity sensor in the stale air
outlet delivery duct from the house upstream of the
exchanger is not active;
ER10 : the CO 2 sensor in the stale air outlet delivery
duct from the house upstream of the exchanger is not
active;
ER11 : the outside temperature is lower than the limit
value;
