IV.5. Electrical connection and operation of the plate heat exchanger

IV.5.a. VORT NRG 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 :
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. VORT NRG EC EH / FIRST / PREMIUM / INFINITE 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.
