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
2) After 24 h from the last By-Pass valve opening
This is a normal system procedure and should not be perceived as a malfunction.
NOTES
- Every time, during By-Pass opening and closing (max 180 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 with remote control display" section.
"Post-ventilation" Function
This kind of function is automatically activate after:
- every time Pre-Heater is turned off (if Pre-Heater installed)
- every time you turn the Appliance off
This is a normal system procedure and should not be perceived as a malfunction
"Program" Function
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. When the
function is active, the message "Progr." Appears on the display: see "Home Page" in the
remote control
display" section. However, the speeds can be manually changed even at specified intervals:
in this case the word "Prg" will flash for 30 minutes and after it will go back to the setted speed of the weekly
time band. If in this 30 min any other function will change the speed, this 30 min timer will go back to 0.
For more details on setting the time slots and dates, see "PRG Crono" in the
display" section. For details on how to activate / deactivate the function, see "Activating / deactivating

both motors will reduce speed to allow repositioning of the by-pass

- if the valve is opened, force the opening;
- if the valve is closed, force the closing.
