"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 e xtracts the Exter nal air (hot) without heat e
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 e xtracts the Exter nal air (cold) without heat e
environmental conditions, a "free cooling" is provided.
