II.3 Positioning
The system must be suspended above or supported on a sufficiently rigid surface (use a vibration damping mounts if
necessary). For ductwork connections, select duct sections to suit the dimensions of the flexible hoses, which should be
properly tensioned. The ducts should be insulated and the first accessories should be installed at a distance of 2.5 times
the duct diameter from the unit (T junction, etc.). Install the unit in such a way that internal components cannot be
damaged by bad weather or ambient temperature either during the installation or subsequent use of the unit.
Install a siphon on each condensate drain pipe. A siphon must not be used for more than one
condensate drain pipe. Caution: the siphons must be connected in the correct manner in order to
ensure that the condensate can drain freely.
The value H must correspond (in mm) to at least the maximum internal negative pressure of the
system x 1.
Example: Dp = 500 Pa = 50 mm CE
_H > 50 mm 2H > 100 mm
Installation of systems in ceilings: units can be suspended on threaded rods. They can also be supported on a frames
attached to the structure of the building, provided that the frames have sufficient load capacity (frames to supplied by the
installer).

IV.5. Electrical connection and operation of the plate heat exchanger
IV.5.a. VO T N G EC version
The heat exchanger bypass is connected in the factory (see diagram in section IV.2)
The automatic operation of the bypass is controlled by two thermostats:
In winter: If the outside temperature is below 18°C (adjustable), the bypass is closed to recover the maximum amount of
heat.
In summer:
COL RECOVERY : If the outside temperature is greater than 24°C (adjustable) the bypass is closed to recover the
maximum amount of heat.
FREE COOLING: If the temperature is between 24° and 18° (adjustable), the bypass is opened to allow outside air to flow
in directly
IV.5.b. FI ST P EMIUM INFINITE AND SMA T version
The heat exchanger bypass is connected in the factory
Its operation is automatically controlled by the CORRIGO controller and the temperature sensors installed as standard in
our VORT NRG EC systems
In winter: When there is a request for a temperature increase, the bypass closes gradually until fully closed to recover the
maximum amount of heat. In cases where this is not sufficient to reach the set temperature, the heater battery will come
into operation.
In summer:
COL RECOVERY: If the outside temperature is greater than the inside temperature and there is a request to reduce the
temperature, the bypass closes gradually until fully closed to recover the maximum amount of heat.
In cases where this is not sufficient to reach the set temperature, the cooling coil will come into operation.
FREE COOLING : If the outside temperature is below the inside temperature and there is a request to reduce the
temperature, the bypass opens by a suitable amount (until fully open) so as to allow fresh outside air to enter the building.
In cases where this is not sufficient to reach the set temperature, the cooling coil will come into operation.

IV.6. Auto defrost
IV.6.a. VO T N G EC version
efrosting is achieved by opening the bypass the moment the defrost temperature (S G) falls below 5° C (thermostat
installed on exhaust duct). The moment the temperature exceeds the threshold value of +5° C, the bypass re-closes.
IV.6.b. FI ST P EMIUM INFINITE and VO T N G EC EH version
This non-modifiable function is automatically controlled by the CORRIGO controller program and by the sensors fitted as
standard in all our dual flow systems. efrosting is achieved by opening the bypass the moment the defrost temperature
(S G) falls below 5° C (sensor installed on exhaust duct). If opening the bypass is not sufficient to defrost the heat
exchanger (if the outside temperature is below -10° C), the flow rate of the fresh air fan will be modulated to maintain the
temperature at the defrost sensor at 5° C.
For INFINITE BE and INFINITE BC versions: the defrost heater battery is installed next to the fresh air intake, upstream
of the plate heat exchanger. This maintains the temperature at the heat exchanger at –5°C, thereby reducing the risk of
frost forming while keeping the bypass as closed as possible. This ensures that the system operates at maximum
efficiency. If the action of the defrost heater battery is not in itself sufficient to defrost the heat exchanger, first bypass
modulation and then fan modulation will be implemented, as described above.
IV.7. Connection of the filter pressure switches
The fresh air filter pressure switch is installed and wired in the factory.
IV.8. Connection of the fan pressure switches
The fan pressure switches are wired and aeraulically connected in the factory

IV.12. Night Cooling
This function is used in summer to cool building interiors at night using outside air. This helps reduce the quantity of cold
air required during the daytime. The Night Cooling function only operates from 00:00 to 07:00. uring Night Cooling, the
hot and cold outputs are locked to 0 V. The heat exchanger delivers exclusively fresh air. On termination of the Night
Cooling stage, the heating is locked to 0V for 60 minutes.
Conditions of operation: definable parameters in section V.5.b.2
• The external temperature exceeds 22° C during daytime
• The timers are set to PV and for shutdown between 00:00 and 07:00.
•The external temperature is below 18° C during Night Cooling operation
• The external temperature exceeds 10° C during Night Cooling operation
• The ambient room temperature exceeds 18° C
uring Night Cooling, the fans run at 85% of full speed. This speed is settable (see section V.5.b.2).
For LOBBY versions, a 24 V output (to be connected by relay) is available across terminals 22 and O7 to force opening
of the area dampers during Night Cooling.
