VI.8 Bypass
This function is automatically controlled using the CORRIGO regulator’s programming and the probes installed as
standard in our VORT NRG EC units.
In winter (FREE HEATING): When heat is required, the bypass closes to recover maximum calories through the plate
exchanger. If this recovery is not adequate to reach the temperature set-point, the water coil valve (if available) will open
or the electric coil (if available) will start.
In summer (FREE COOLING): The bypass closes when the outside temperature is higher than the inside temperature
to prevent the outside heat from entering directly. If the outside temperature is lower than the inside temperature, the
bypass opens to get the cool outside air.
On the VORT NRG 6000-8000 models, the single servomotor is wired in the same manner as the small shutter.
