Use

When switched on led 4 will flash to indicate the correct power supply of the product, during the first 3 minutes of operation,
the appliance re-positions the bypass valve.
The engines then restart at the previously set speed.
Note: this system behaviour is normal and should not be considered a fault.
The product provides for continuous type operation.
"Heat recovery" Function
This kind of function is normally actived, except when:
- automatic functions: "No-Frost", "By-Pass" and "Post-ventilation" are active;
Stale air (B) is expelled outside by means of an outside duct (D) while, at the same time, renewed air (C) 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 (A).
"No-Frost" Function
The function is activable if 2 minutes are left after Appliance turning On.
"No-Frost" 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-Frost" appears on the display;
- User can not change ventilation Speeds;
- "Program" function is NOT enabled.
The main scope of the "No-Frost" 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-Frost" procedure has proved insufficient and the appliance goes into protected mode for one hour,
with the motors off, following which it will restart automatically.
NOTE: Restarting is automatic and don' t need User presence
"By-Pass" Function
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 extracted directly from inside (B), without passing through the heat exchanger. The flow of air vented
to the inside (A) continues to pass through the heat exchanger, that will not be effective anymore.
"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).
NOTE: The "By-Pass" automatic function is deactivated when:
- External air temperature is less than 15°C;
- "No-Frost" function is active.
Example: Autumn case (sunny afternoon)
External air Temperature = 23°C;
Indoor air Temperature = 20°C;
Bypass air Temperature = 24°C.
Appliance extracts the External air (hot) without heat exchanging with the Indoor air (cold). In this way, thanks to
environmental conditions, a "free heating" is provided.
Example: Spring case (morning)
External air Temperature = 16°C;
Indoor air Temperature = 20°C;
Bypass air Temperature = 18°C.
Appliance extracts the External air (cold) without heat exchanging with the Indoor air (hot). In this way, thanks to
environmental conditions, a "free cooling" is provided.
"By-Pass" Valve check
A Valve check is performed:
1) When the appliance is switched on both motors will reduce speed to allow repositioning of the by-pass valve.
After, motors will start up again.
