bypass
This function is automatically controlled using the CORRIGO regulator's programming and the probes installed as stan-
dard in our double-flow CARMA
®
units.
In winter: 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 battery valve will open or the electric battery 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.
For the CARMA 9048-9070, the single servomotor is wired in the same manner as the small shutter.
