III.2 OPERATING SEQUENCE

Except VORT ENERGY EC versions

Start-up sequence:

• The recovery fan or VAR pressure monitoring mode starts at the same moment the fresh air damper is operated.

• The blower fan or VAR pressure monitoring mode starts at the same moment the recovery air damper is operated.

• Temperature control starts in accordance with the configured control mode. Electrical heating (if configured) starts on
the flow controller only (flow reversal). Pumps that have not yet been activated will start up.

• The alarm management function is activated after the pre-set time period. At this point the system is operating in
normal mode.

Conditions for startup:
The system starts up when one of the following conditions is met:

• The programmed schedule (timer) for normal speed or low speed operation is on “Run”.

• The system is started manually from the CORRIGO controller.

• One of the digital inputs for forced run is activated.

54

ENGLISH

!

Shutdown sequence:
The system shutdown procedure is as follows:

• Deactivation of the alarm management function.

• Deactivation of electrical heating (if configured).
After a certain time interval (individually pre-set for each fan), the fans are switched off.

•

• The fresh air and return air dampers are closed.

• The signals sent to the actuators are re-set to zero and the pumps are stopped.

Conditions for shutdown:
The system shuts down when one of the following conditions is met:

• The programmed schedule (timer) for normal speed or low speed operation is on “Stop” and the forced run signal is
also on “Stop”.

• Activation of the external shutdown command.

• The system is shut down manually from the CORRIGO controller.

• Intervention of an alarm configured with the supplementary shutdown function. The system will restart automatically
once the alarm has been reset.

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:
COLD  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. FIRST PREMIUM INFINITE AND SMART 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:
COLD 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

V.6.a. VORT NRG EC version

I

Defrosting is achieved by opening the bypass the moment the defrost temperature (SDG) falls below 5° C  (thermostat

nstalled on exhaust duct). The moment the temperature exceeds the threshold value of +5° C, the bypass re-closes.

i

IV.6.b. FIRST PREMIUM INFINITE and VORT NRG EC EH version

his non-modifiable function is automatically controlled by the CORRIGO controller program and by the sensors fitted as

T
standard in all our dual flow systems. Defrosting is achieved by opening the bypass the moment the defrost temperature
(SDG)  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.

The fresh air filter pressure switch is installed and wired 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

ir required during the daytime. The Night Cooling function only operates from 00:00 to 07:00. During Night Cooling, the

a
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

During 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 DO7 to force opening

of the area dampers during Night Cooling.

IV.13. Changeover coil

Be careful not to impede opening of the access doors (with pipes, cables, etc.)
The coil is already installed in the system, the antifreeze thermostat is connected. The 3-way valve must be connected

electrically. If a cooling or changeover battery is used in the duct, move the supply sensor downstream of the coil.
