Use
Appliance is automatically managed by an electronic control system. Appliance can automatically choose the most
suitable operating mode, depending on the outside temperature.
When the appliance is switched, both motors will stop to allow repositioning of the by-pass valve. After, motors will start
up again. OTE: this is a normal system procedure and should not be perceived as a malfunction.
“Heat recovery” Function
ig. 3
This kind of function is normally actived, except when:
- automatic functions: “No- rost”, “By-Pass” and “Post-ventilation” are active;
- the manual function: “By-Pass MAN” is active.
Stale air (B) is expelled outside by means of an outside duct (D) while, at the same time, renewed air (A) is also extracted
from the outside. This renewed air is heated by the combined action of the air/air heat exchange. The renewed air enters
into the room by the Cleaned air duct (C).
“ o-Frost” Function
The function is activable if 30 minutes are left after Appliance turning On.
“No- rost” function is automatically active when the Appliance check a too low External air temperature, for a certain
time. When the function is active:
- the message "No- rost" appears on the display;
- User can not change ventilation Speeds;
- “Program” function is NOT enabled.
The main scope of the “No- rost” function is to avoid appliance damaging, because of too low temperatures.
When the message "Alarm!" and “Lock!” appears on the display: it rapresent a “no-frost timeout”.
This means that “No- rost” procedure has proved insufficient and the appliance goes into protected mode for one hour,
with the motors off, following which it will restart automatically.
OTE: Restarting is automatic and don’ t need User presence.
“By-Pass” Function
ig. 3
This type of operation is automatically set and it is usefull to ventilate the apartment without heat transfer. With the bypass
valve open, air can be introduced directly from outside, without passing through the heat exchanger. The flow of air vented
from inside continues to pass through the heat exchanger.
“By-Pass air Temperature” rapresent the “Desidered air temperature”: according to this, the Appliance
activates/deactivates the bypass valve. User can select the “By-Pass air Temperature” into a range of temperatures:
from 15°C to 30°C. The preset “By-Pass air Temperature” value is 18°C (default).
OTE: The “By-Pass” automatic function is deactivated when:
- External air temperature is less than 15°C;
- “No- rost” function is active.
Exa ple: Autu n case (sunny afternoon)
External air Te perature = 23°C;
Indoor air Te perature = 20°C;
Bypass air Te perature = 24°C.
Appliance extracts the External air (hot) without heat exchanging with the Indoor air (cold). In this way, thanks to
environ ental conditions, a “free heating” is provided.
Exa ple: Spring case ( orning)
External air Te perature = 16°C;
Indoor air Te perature = 20°C;
Bypass air Te perature = 18°C.
Appliance extracts the External air (cold) without heat exchanging with the Indoor air (hot). In this way, thanks to
environ ental conditions, a “free cooling” is provided.
“By-Pass” Valve check
A Valve check is performed:
1) When the appliance is switched both motors will stop to allow repositioning of the by-pass valve.
After, motors will start up again.
E GLISH

9
2) After 24 h from the last By-Pass valve opening Appliance forces a By-pass activating to check the effective
position of the valve:
- if the valve is opened, force the opening;
- if the valve is closed, force the closing.
This is a normal system procedure and should not be perceived as a malfunction.
OTES
- Every time, during By-Pass opening and closing (max 120 sec), Appliance automatically reduces fan-ventilators speeds
to the 20%, in order to help the By-Pass valve movement.
- In case of Temperature sensors anomalies, By-Pass valve will stay preventively closed.
When the function is active, the message "By-Pass" appears on the display: see "Home Page" in the "Operation" and
use ".
“Post-ventilation” Function
This kind of function is automatically activate after:
- every time Pre-Heater is turned off (if Pre-Heater installed) both motor-fans active (about 3 minutes) to avoid
overheating;
- every time you turn the Appliance off indoor air is extracted at the max speed (about 3
minutes) to avoid condensate presence on the heat
exchanger.
This is a normal system procedure and should not be perceived as a malfunction.
“Program” Function (only OT UK Markets)
Special mode of operation: manually enabled and allows the user to program weekly air speeds. In fact, it allows you to
assign up to 6 time bands with different speeds, including stopping the equipment. At unspecified intervals the equipment
will operate at the speed set off the Program. When the function is active, the message "Progr." Appears on the display:
see "Home Page" in the "Operation and Use" section. However, the speeds can be manually changed even at specified
intervals: in this case the message “Man.” appears on the display.
or more details on setting the time slots and dates, see "PRG Crono" in the "Operation and Use" section. or details
on how to activate / deactivate the function, see "Activating / deactivating Program" in the "Operation and Use" section.
"Holiday" Function
Special mode of operation: manually enabled and useful if the user leaves the room for a longer period of time.
Operation includes:
- fixed "Minimum ” speed (no other speeds, no O equipment);
- environment sensors not enabled (remote inputs not actived);
- bypass always closed.
When the mode is active, the message "Holiday" appears on the display: see "Home Page" in the "Operation and Use"
section.
OTE: Activating the Mode “Holiday” will be deactivate other product functionings/selections.
To re-activate other product functionings/selections, need to deactivate the Mode “Holiday” before.
or more details on how to activate / deactivate the function, see "Activating / deactivating Holiday" in the "Operation and
Use".
“By-Pass MA ” Function
Special mode of operation: manually enabled and useful if you want to force air replacement without heat recovery.
The operating principle is the same as: "By-Pass" function.
OTE: If manually enabled, the “By-Pass MAN” function will remain active for 12 h. After this period, the “By-Pass MAN”
function will come back to: Not enabled.
OTE: (In case of “By-Pass MAN” Enabled) However you can manually deactivate the function, setting “NO” on “By-Pass
MAN Menu”. After Deactivating, the operating principle will be come back the same of “By-Pass” function.
OTE: In case of “No- rost” function active, you can not manually activate the “By-Pass MAN” function.
When the function is active, the message "By-Pass" flashing appears on the display: see "Home Page" in the "Operation"

enabled:
- Un-Balan: when the air external temperature is too cold, if the function is Enabled, motor-fans automatically
start to run, following pre-set ventilation programs. Appliance will try to use different ventilation
procedures that take advantage of extracted air (warm) to self-heating.
ATTE TIO : The appliance is default setted with “Un-Balan”: Enabled (factory production).
To Activating/deactivating the function, see: “Activating/deactivating the function Un-Balan”.
- Heater: (only in case of installing the Pre-Heater optional)
when the air external temperature is too cold, if the function is Enabled, the Pre-Heater starts to
run, for a certain time. Appliance will try to heat using the electric heater installed on the resh air
duct (See Fig. 3, Letter (A)).
ATTE TIO : The appliance is default setted with “Heater”: NOT Enabled (factory production).
So, in case of Installing Pre-Heater, the Installer have to manually activate the function.
To Activating/deactivating the function, see: “Activating/deactivating the function Heater”.
ATTE TIO : In case of “Heater” function NOT Enabled, the Pre-Heater will not works, also if
correctly wired.
ATTE TIO : In case of NOT Installed Pre-Heater, keeping “Heater” Enabled, will
produce abnormalities on “No rost” function.
- Heat Forc: (only in case of installing the Pre-Heater optional)
when installing the Pre-Heater, a “working test” is possible forcing Pre-Hater activation.
In case of “Heat Forc” Enabled, the Pre-Heater will run for 15 seconds;
So after that, the function “Heat Forc” will come back “N T Enabled”.

Maintenance and cleaning
ig. 35-36
Ordinary maintenance - Filters
Recommended maintenance intervals: because levels of air pollution depend typically on geographical location and are
variable, the life of the filters will be similarly variable. With this general consideration in mind, check following alarms for
filter maintenance:
• Pre-alarm: actives the notice about filters checking and cleaning (See:Operation and Use: Pre-alarm:“Checking filters”)
• Alarm: actives the notice about clogged filters (See: Operation and Use: Alarm:“ ilters replacing”)
Resetting filters timer (See: Operation and Use: “User operation menu”, “Resetting filters timer”) is resetted also the
counter.
OTE ailure to clean or replace filters can seriously affect system efficiency, causing:
- increased pressure losses in the air circulation system and reduced airflow;
- drop in system performance and comfort levels caused by pressure losses.
In case of filters cleaning or filters replacing
ig. 35 - ilters removing
