MODULATING VENTILATION
As with step ventilation, the management logic for
modulating ventilation offers two possible operating modes:
• AUTOMATIC operation
• fixed-speed OPERATION
The operating percentage is selected by pressing the UP/
DOWN keys, while automatic ventilation comes on when
ventilation is set below the minimum (20%) or above the
maximum (100%) values.

WATER CONSENT
Regardless of what type of fan is installed (step or
modulating), ventilation depends on the system's water
temperature control. Depending on the work mode, we will
have different consent thresholds for heating and cooling.
COOLING
HEATING
Failure to have this consent, when the thermostat sends
a signal, will be displayed by the flashing symbol of the
mode that is currently in operation Cooling or Heating. This
enabling signal will be ignored if:
• the water probe is not required or it is in alarm conditions
• Cooling with 4-pipe configurations
USER MANUAL

For configurations with 4 speeds, ventilation
for heating is delayed by 0.5°C to allow for an
initial natural convection phase.
