IV.6. Auto defrost
IV.6.a. VORT NRG EC (BASIC VERSION)
Defrosting is achieved by opening the bypass the moment the defrost temperature (SDG) 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. FIRST PREMIUM INFINITE and VORT NRG 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. 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.
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
