Vortice VORT HRI PHANTOM BP Manual De Instrucciones página 34

ENGLISH
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 on, both motors will run at a really slow speed for 3 minutes to allow repositioning of the
by-pass valve. After, motors will start up again. NOTE: this is a normal system procedure and should not be perceived as
a malfunction.
The appliance is wired to a special dedicated control panel, the functions of which are described further on.
This model can be used in combination with a Vortice preheater, which must be fitted and set up by the installer.
The minimum distance of the preheater from the appliance is 500 mm.
"Heat recovery" Function
Fig. 3
This kind of function is normally actived, except when:
- automatic functions: "No-Frost", "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).
"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
Fig. 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 extracted directly from inside (B), without passing through the heat exchanger. The flow of the
introduced (C) air vented continues to pass through the heat exchanger which will no longer be effective.
"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.
